Observation of the analgesic effect of superficial or deep anterior serratus plane block on patients undergoing thoracoscopic lobectomy

The effectiveness of anterior serratus plane block in postoperative analgesia of thoracic surgery is beginning to emerge. Currently, there are 2 methods of anterior serratus plane block: deep serratus plane block (DSPB) and superficial serratus plane block (SSPB). In clinical practice, there is no an unified view regarding the advantages and disadvantages between 2 methods. This study aimed to observe and compare the analgesic effects of 2 methods on patients undergoing thoracoscopic lobectomy, in order to provide some suggestions for anesthesiologists when they choose anterior serratus plane block to perform postoperative analgesia for patients.Patients were randomly divided into 3 groups (21 patients/group):

• 1.general anesthesia group (P group);
• 2.combined general anesthesia and SSPB group (S group), and
• 3.combined general anesthesia and DSPB group (D group).

The patients in groups S and D received 0.4 ml/kg of 0.375% ropivacaine for ultrasound-guided block after surgery. Postoperatively, flurbiprofen was used for rescue analgesia.Visual analog scale (VAS) pain scores were recorded at 6 hours, 12 hours, and 24 hours after surgery, and rescue analgesia, post-operative nausea, and vomiting were reported within 24 hours after surgery. At 6 hours, 12 hours, and 24 hours, the VAS scores and the rescue analgesia rates in groups S and D were significantly lower than those in group P (all P < .001). With prolonging time, the VAS in group D was significantly increased by 0.11 per hour as compared with that of group P (P < .0001); VAS in group D was significantly increased by 0.12 per hour as compared with that of group S (P < .0001).Ultrasound-guided anterior serratus plane block can provide adequate analgesia for patients undergoing thoracoscopy lobectomy. SSPB can significantly improve VAS scores as compared to DSPB at 24 hours.     

The effects of target-controlled infusion of lidocaine undergoing vocal cord polypectomy: A randomized controlled trial (CONSORT compliant)

Background:The present study aimed to assess the efficacy and safety of general anesthesia-assisted target-controlled plasma infusion of lidocaine in patients with vocal cord polypectomy using a supporting laryngoscope.Methods:In total, 80 patients undergoing vocal cord polypectomy using a supporting laryngoscope were randomly divided into an intervention group and a control group; each group contained 40 subjects: both groups received general anesthesia; subjects in the intervention also received an additional 3 mg/L of lidocaine by target-controlled plasma infusion during induction and maintenance of anesthesia; heart rate (HR) mean arterial pressure (MAP), propofol and urapidil consumption (Uradil, which is a blood pressure drug that blocks alpha-1, is called Urapidi Hydrochloride Injection. It is produced by Germany, the enterprise name is Nycomed Deutschland GmbH, the import drug registration number is H20090715, and it is widely used in China), recovery time, and cough score (measured by Minogue et al''s 5-grade scoring method) during extubation, and throat pain score (measured by visual analogue scale,[VAS]) after extubation and adverse events were recorded.Results:Significant differences were observed in HR (P < .05) and MAP (P < .05) immediately after intubation (T2), immediately after the operation starting to support laryngoscope exposure (T3), immediately after operation field adrenergic tampon hemostasis (T4), and 5 minutes after hemostasis (T5) between the 2 groups, and significant differences were also observed in HR (P < .05) before intubation (T1). Moreover, significant differences were observed in propofol consumption (P < .05), urapidil consumption (P < .05), cough score during extubation (P < .05), and throat pain score after extubation (P < .05). However, no significant difference was observed in the recovery time (P > .05). Furthermore, no adverse events were detected in either group.Conclusion:The results of this study showed that target-controlled plasma infusion of lidocaine can reduce propofol consumption in patients undergoing vocal cord polypectomy by supporting laryngoscopy, and the hemodynamics are more stable and reduce the coughing reaction in the wake period and throat pain after extubation without adverse events.     

Single-stage intraoperative ERCP combined with laparoscopic cholecystectomy versus preoperative ERCP Followed by laparoscopic cholecystectomy in the management of cholecystocholedocholithiasis: A meta-analysis of randomized trials

ObjectivesThe optimal treatment strategy for cholecystocholedocholithiasis is still controversial. We conducted an up-to-date meta-analysis to compare the efficacy and safety of the intra- endoscopic retrograde cholangiopancreatography (ERCP) + LC procedure with the traditional pre-ERCP +  laparoscopic cholecystectomy (LC) procedure in the management of cholecystocholedocholithiasis.MethodsWe searched the PubMed, Embase, Cochrane Library, and Web of Science databases up to September 2020. Published randomized controlled trials comparing intra-ERCP + LC and pre-ERCP + LC were considered. This meta-analysis was performed by Review Manager Version 5.3, and outcomes were documented by pooled risk ratio (RR) and mean difference (MD) with 95% confidence intervals.ResultsEight studies with a total of 977 patients were included in this meta-analysis. There was no significant difference between the two groups regarding CBD stone clearance (RR = 1.03, P = .27), postoperative papilla bleeding (RR = 0.41, P = .13), postoperative cholangitis (RR = 0.87, P = .79), and operation conversion rate (RR = 0.71, P = .26). The length of hospital stay was shorter in the intra-ERCP + LC group (MD = −2.75, P < .05), and intra-ERCP + LC was associated with lower overall morbidity (RR = 0.54, P < .05), postoperative pancreatitis (RR = 0.29, P < .05) and cannulation failure rate (RR = 0.22, P < .05).ConclusionsIntra-ERCP + LC was a safer approach for patients with cholecystocholedocholithiasis. It could facilitate intubation, shorten hospital stay, and lower postoperative complications, especially postoperative pancreatitis, and reduce stone residue and reduce the possibility of reoperation for stone removal.     

Outcomes of and factors influencing the arthroscopic treatment of rotator cuff injury with the patient in the lateral-lying and beach chair positions

To compare the postoperative effects of arthroscopy for rotator cuff injury with patients in the lateral-lying position (LLP) and beach chair position (BCP), and to identify factors influencing these effects.Data from patients with rotator cuff injuries who underwent shoulder arthroscopy in the LLP (n = 115, 53.24%) or BCP (n = 101, 46.76%) between January 2013 and 2016 and were followed for >3 years were analyzed. The American Shoulder and Elbow Surgeons shoulder score, University of California at Los Angeles shoulder score (UCLASS), and visual analog scale (VAS) score were used to evaluate patients’ shoulder function and pain preoperatively and at the last follow-up examination. The abduction and lateral rotation angles were measured. The influences of patient characteristics were compared between the LLP and BCP subgroups defined by UCLASSs (excellent, good, acceptable, poor).Postoperative injury characteristics, UCLASSs, and VAS scores were better in the LLP group than in the BCP group (all P < .05). Among patients with good UCLASSs, preoperative pain duration was longer in the LLP group than in the BCP group (P < .05); among those with acceptable UCLASSs, this duration was longer in the BCP group than in the LLP group (P < .05). The preoperative flexion angle differed between groups (P < .05). Among patients with excellent and good UCLASSs, the postoperative external rotation angle was greater in the LLP group than in the BCP group (P < .05). The LLP group contained more excellent UCLASSs than did the BCP group (P < .05). It also contained more small, medium, and large tear cases than did the BCP group (all P < .05).The effect of arthroscopy for rotator cuff injury was better when the operation was performed with the patient in the LLP. Either position is suitable for the arthroscopic treatment of partial rotator cuff tears. The LLP is more suitable in cases of small and medium-sized tears and those with large preoperative lateral rotation angles. The BCP should be used for patients with large preoperative flexion angles.     

Analysis of the curative effect of percutaneous kyphoplasty in the treatment of osteoporotic vertebral compression fracture with intravertebral clefts

Kummell''s disease is a delayed vertebral collapse fracture caused by posttraumatic osteonecrosis. It is a special type of osteoporotic vertebral fracture in the elderly. This study compares and analyzes the difference in the curative effect of 2 kinds of osteoporotic vertebral compression fracture (OVCF) in the presence of fracture or not in the vertebral body, and provides a clinical reference for the application of percutaneous kyphoplasty (PKP).This research is a kind of retrospective analysis from January 2012 to January 2015, PKP was used to treat 165 patients with osteoporotic vertebral compression fracture. The patients were divided into 2 groups: Intravertebral clefts group (group A) and none-intravertebral clefts group in vertebral body (group B). Bone mineral density (BMD), bone cement injection (BCI), Visual analogue scale (VAS) score before and after surgery, anterior, central and posterior height of vertebral body (before and after surgery) and Cobb angle of injured vertebra (before and after surgery) were compared between the 2 groups.Surgeries for 165 patients in the 2 groups were successfully completed, and 226 fractured vertebrae were performed through bilateral puncture approach to strengthen the vertebral body. Intraoperative injection of bone cement (ml) was 4.25 + 1.29 (range: 2.6–7.8). There were statistically significant differences in bone cement injection quantity between the 2 groups (P < .05), and in bone cement leakage (P > .05) as well as the Postoperative VAS score (P < .05). However, There was no statistical difference in VAS score before surgery between the 2 groups (P > .05). The results indicated that the pain relief degree of OVCF patients without intravertebral clefts is better than that in the vertebral body. No statistical difference was found in Cobb Angle before and after surgery (P > .05), as well as the correction rate of the injured vertebrae before and after surgery (P > .05). There was no statistical difference in the degree of recovery of the anterior, middle and posterior margins of the injured vertebrae after surgery (P > .05).PKP treatment led to better degree of pain relief in OVCF patients without intravertebral clefts, and less bone cement was injected into the surgery.     

Clinical efficacy of zoledronic acid combined with percutaneous kyphoplasty in the prevention and treatment of osteoporotic vertebral compression fracture: A systematic review and meta-analysis

Objective:The aim of this study is to investigate the clinical efficacy of zoledronic acid (ZOL) in the treatment and prevention of osteoporotic vertebral compression fractures (OVCF) after percutaneous kyphoplasty (PKP) for elderly patients.Methods:The PubMed, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang, VIP, and Embase were investigated through June 2020. All randomized controlled trials (RCT) involving ZOL injections for OVCF were enrolled. Outcome indicators included the bone mineral density (BMD), Visual Analog Scale (VAS), recompression vertebral fracture (RVF), Oswestry Disability Index (ODI), and bone metabolism (Procollagen type I N-terminal propeptide [PINP] and βcross-linked C-telopeptide of type I collagen [β-CTX]), bone cement leakage. Review Manager 5.3 was used to analyze these indicators.Results:In this study,

• (1)Eight studies had met the eligibility criteria, a total of 578 participants were involved (285 and 293 in the experimental (ZOL) group and control [no ZOL] group, respectively).
• (2)The BMD scores of patients with OVCF in the experimental group were significantly higher than that in the control group (P < .05).

The VAS scores were significantly different between the 2 groups at the 6, 12 months follow-up (P < .05). After PKP operation, ZOL injections reduced the rate of RVF (P < .05). In the comparison of ODI scores, the experimental group improved compared with the control group (P < .05). Respectively, the bone metabolism of patients with OVCF after ZOL was better than that of patients in control group (P < .05).Conclusion:Zoledronic acid had a significant effect on the treatment and prevention of OVCF in elderly osteoporotic patients after PKP. Due to the limited quality and data, more high-quality studies are needed to confirm the results of this meta-analysis.     

Effect of ketorolac tromethamine combined with dezocine prior administration on hemodynamics and postoperative analgesia in patients undergoing laparoscopic hernia repair

Objective:To observe the effect of Ketorolac tromethamine combined with dezocine prior administration on hemodynamics and postoperative sedation in patients undergoing laparoscopic hernia repair.Methods:100 male patients aged 60 to 80 years old, a line to elective laparoscopic inguinal hernia repair, were randomly divided into four groups: control group (Group A) and dezocine group (Group B), ketorolac tromethamine group (Group C), ketorolac tromethamine combined with dezocine group (Group D). Patients were administrated with 0.1 mg/kg dezocine in Group B, 0.5 mg/kg ketorolac in Group C, 0.1 mg/kg dezocine, and 0.5 mg/kg ketorolac in Group D, and with an equal dose of normal saline in group A. The heart rate (HR) and mean arterial pressure (MAP) of patients in 4 groups were recorded at each time point as follows, T0 (enter the operating room), T1 (before skin resection), 10 min after pneumoperitoneum (T2), mesh placement (T3), and laryngeal mask extraction (T4). Operation time, awakening time (time from drug withdrawal to consciousness recovery), the dosage of propofol, sufentanil, remifentanil, and intraoperative vasoactive drug dosage were recorded to compare. Visual analog scale score and sedation Ramsay score were evaluated 1, 6, 12, and 24 hours after extubation.Results:There was no significant difference in operation time, anesthesia recovery time, sufentanil dosage, and vasoactive drugs among all groups. The amount of propofol in Group B and D was less than that in Group A and C (P < .05), and there was no difference between Group B and D, A and C (P > .05). The amount of remifentanil in Group B, C, and D was less than that in Group A (P < .05), and Group D was less than B and C (P < .05). After extubation, HR and MAP were significantly higher than before (P < .05). Compared with T0, HR and MAP increased in each group at T4, but MAP and HR in Group D increased the least (P < .05). There were significant differences between Group B, C, D, and A, MAP and HR fluctuated little during extubation (P < .05), but there was a significant difference between Group D and B, C (P < .05). Visual analog scale scores of Group B, C, and D were lower than those of A at 1, 6, and 12 hours after surgery (P < .05), and there was a significant difference between Group D, and B, C (P < .05). Ramsay scores in Group B and D were higher than those in A and C at 1 and 6 hours after the operation (P < .05). There was no difference in the incidence of adverse reactions among groups.Conclusion:The prophylactic use of ketorolac tromethamine and dezocine before laparoscopic inguinal hernia repair can reduce hemodynamic disorder during anesthesia recovery, increase postoperative sedative and analgesic effects.     

Effectiveness of nursing Intervention on anxiety,psychology and self-efficacy among elderly patients with acute coronary syndrome after percutaneous coronary intervention: An observational cohort study

The aim of the present study is to investigate effect nursing intervention on anxiety, psychology and self-efficacy among elderly patients with acute coronary syndrome after percutaneous coronary intervention, and the correlation between patients’ anxiety, psychology and self-efficacy and nursing intervention.One hundred thirty six patients with acute coronary intervention were randomly divided into the experimental group (n = 68) and the control group (n = 68). The experimental group received nursing intervention measures, and control group received routine nursing. We measured the depression, anxiety score of the 2 groups before and after nursing and multiple regressions was to analysis the correlation between patients’ anxiety, psychology and self-efficacy and nursing intervention.The nursing intervention effect of the 2 groups after intervention were improved before intervention (P < .05), and the Hospital Anxiety and depression scale (HADS) in the was decreased than that of the control group after psychological intervention. The general self-efficacy scale scores of experimental group were obviously improved after receiving the intervention, and the scores in the experimental group were much higher than the control group after receiving the intervention, namely (P < .05). Furthermore, Single regression analysis showed that single (Marital status) (r = 0.367, P < .001), divorced or separated (Marital status) (r = 0.338, P < .001), Widowed (Marital status) (r = 0.458, P < .001), nursing intervention (r = 0.431, P < .001) and Length of hospital stay (r = 0.276, P = .003) showed a significant correlation with patients’ anxiety, psychology and self-efficacy. Multiple regression analysis showed that Length of hospital stay (P = .001) and nursing intervention (P < .001) were significantly correlated with patients’ anxiety, psychology and self-efficacy.Nursing intervention maybe significantly improve patients’ anxiety, psychology and self-efficacy, and nursing intervention was significantly correlated with patients’ anxiety, psychology and self-efficacy. Considering the limited number of studies analyzed, large sample-size clinical trials are necessary to verify the effect nursing intervention on anxiety, psychology and self-efficacy among elderly patients with acute coronary syndrome after percutaneous coronary intervention.     

The 95% effective dose of nalbuphine in patient-controlled intravenous analgesia for patients undergoing laparoscopic total hysterectomy compared to equivalent sufentanil: Retraction

Purpose:To evaluate the 95% effective dose of nalbuphine in patient-controlled intravenous analgesia (PCIA) by the sequential method and compare the analgesia efficacy with the equivalent dose of sufentanil on patients undergoing laparoscopic total hysterectomy.Methods:In the first part, we defined a successful analgesia as the highest VAS ≤3 in 24 hours postoperatively. On the contrary, a failed analgesia was the highest VAS>3. According to the last patient''s outcome, the next patients would be given an increase or decreased dose grade. This process ended up with 9 cross-over points. In the second part, 60 patients undergoing laparoscopic total hysterectomy were selected. They were randomly divided into 2 groups (n = 30 each group): receiving sufentanil 1.78 μg/kg (group S) and nalbuphine 1.78 mg/kg (group N). PCIA pump was given at the end of the operation with 5 mL bonus loading. The total amount of PCIA was 100 mL and programmed to deliver 0.5 mL each time with a lockout interval of 15 minutes and the background infusion amount of 2 mL/h. The VAS score and Ramsay score of were collected after the operation, the number of effective pressing times of PCIA were also recorded. Adverse reactions were documented in detail.Results:The 95% effective dose of nalbuphine in PCIA on patients undergoing laparoscopic total hysterectomy was 1.78 mg/kg. There was no significant difference in VAS between the sufentanil group and the nalbuphine groups (P > .05), but the number of the use of PCIA in the group S was more than that in the group N obviously (P <.05). The group S has a lower ramsay sedation score than group N at every time point. (P <.05). The incidence of nausea and vomiting was not statistically significant differences between two groups in the first 24 hours after colonoscopy (P >  q .05).Conclusion:Nalbuphine 1.78 mg/kg in PCIA is recommended for the patients undergoing laparoscopic total hysterectomy. And nalbuphine is a reasonable alternative to sufentanil when used in PCIA.     

Comparison of epidural,spinal, and saddle block for holmium laser enucleation of prostate (HoLEP): A prospective randomized,comparative study

Background:Holmium laser enucleation of the prostate (HoLEP) has become an important treatment modality for benign prostate hypertrophy. The aim of the present study was to compare regional anesthesia methods for HoLEP operation and to determine the optimal technique.Methods:Sixty patients with American Society of Anesthesiologists scores of I-III were randomly allocated into 3 groups. Patients in group E received an epidural block with 75 mg of bupivacaine plus 50 μg of fentanyl. In group S, 15 mg of bupivacaine and 50 μg fentanyl were used for spinal anesthesia. In group SA, patients received saddle block with 15 mg of bupivacaine and 50 μg of fentanyl.Results:Time to T10 dermatome block and to maximal level block were longest in group E (P < .05), and maximal sensorial block level was higher in group E than group SA (P < .05). There was a significant difference in postoperative motor block, but no difference in systolic blood pressure and heart rate.Conclusion:Among 3 techniques, saddle block might be preferable in HoLEP because an adequate sensorial level was achieved with lower motor block and stable hemodynamics.     

Comparison of lidocaine and ropivacaine stellate ganglion blockade in treating upper limb postherpetic neuralgia

To provide a basis for treating postherpetic neuralgia (PHN), we compared the efficacy of lidocaine and ropivacaine stellate ganglion block (SGB) in PHN treatment in the upper limbs.Data from 252 patients with upper-limb PHN were retrospectively analyzed. The lidocaine group (n = 118) was treated with oral pregabalin capsules 75 mg twice a day, tramadol hydrochloride sustained release tablets 100 mg twice a day, and amitriptyline 25 mg once at night combined with ultrasound-guided lidocaine SGB; the ropivacaine group (n = 134) was orally administered the same medicines combined with ultrasound-guided ropivacaine SGB. The visual analog scale (VAS), self-rating anxiety scale (SAS), and adverse reactions were compared between the groups before treatment and at 1 week, 1 month, and 3 months after treatment.There were no significant differences between the lidocaine and ropivacaine groups in terms of sex, age, height, weight, and pain duration (P > .05). There was no significant difference between the groups in VAS and SAS scores before treatment (P > .05). At 1 week, 1 month, and 3 months after ultrasound-guided SGB treatment, the VAS and SAS scores were significantly lower in the ropivacaine group than in the lidocaine group (P < .05). There were no significant differences between the groups in terms of adverse reactions (P > .05).For ultrasound-guided SGB treatment of upper limb PHN, ropivacaine is superior to lidocaine. Ultrasound-guided ropivacaine SGB is safe and effective for the treatment of upper limb PHN.     

Comparison of 2940 nm Er: YAG laser treatment in the microlaser peel,fractional ablative laser,or combined modes for the treatment of concave acne scars

Objective:To compare and analyze the effects of Er:YAG laser treatment in the microlaser peeling, fractional ablative laser, or combined modes for the treatment of concave acne scars.Method:Ninety patients of concavity acne scar were randomly assigned to three different groups:microlaserpeeling mode group (MM group), fractional ablative mode group (FM group) and combined mode group (CM group). MM group received microlaserpeeling mode with depth of 60 μm and a repetition rate of 20%, FM group received fractional ablative mode with depth of 300 μm and a fractional density of 8%, and CM group received a fractional depth of 200 μm, density of 8%, and a peeling depth of 30 μm, repetition rate of 20%. All patients were evaluated for their treatment effects and side effects 30 days after treatment, including the treatment satisfaction, the ECCA grading scale, pain score and pigmentation level.Results:According to the effect satisfaction of patients’ self-assessment, the difference among the three groups was statistically significant (P < .05), the CM group was better than the other two groups, but there was no significant difference between the FM group and the MM group (P > .05). About the ECCA grading scale 30 days after treatment, the statistical result among the three groups was significant (P < .05), the CM group is much lower than the FM group which is approximately equal to the MM group. There was statistical difference in pain score among the three groups and every two groups (P < .05), the CM group had the highest pain score, while FM group had the lowest. About the pigmentation level, there was statistical difference among the three groups (P < .05), FM group had the lightest pigmentation, while the CM group had the heaviest.Conclusions:Three treatment modes are all effective in treating the concavity acne scar. Among the three modes, CM group is best effective, also accompanied with the most severe side effect; FM group achieves the best balance between treatment effect and side effect. The treatment practices indicate that when the Er:YAG laser with a wavelength of 2940 nm is used to treat concavity acne scars, the right treatment mode should be subject to the severity of the scar.     

Intraoperative periarticular injection can alleviate the inflammatory response and enhance joint function recovery after hip arthroplasty in elderly patients with osteoporotic femoral neck fractures

Purpose:This study aimed to investigate the potential beneficial effects of periarticular injection (PAI) of multimodal drugs on the inflammatory response and joint function after hip arthroplasty in elderly patients with osteoporotic femoral neck fractures.Methods:Fifty six elderly patients with unilateral osteoporotic femoral neck fractures were randomly allocated to 2 groups: the PAI group, which received the multimodal drug PAI intraoperatively before incision closure, and the control group, which received an injection of saline at the same time as placebo. The C-reactive protein (CRP), interleukin-1β (IL-1β), and IL-6 levels as well as the erythrocyte sedimentation rate (ESR) in peripheral venous blood samples were measured, along with the Visual Analogue Scale (VAS) score with activity and Harris hip score preoperation at 1, 2, 4, 7, and 14 days as well as 1 and 3 months post-operation.Results:The 2 groups were comparable in sex and age, and no significant differences were observed in the preoperative CRP, IL-1β, and IL-6 levels, ESR, VAS score, or Harris hip score between the 2 groups (all P > .05). However, during the postoperative period, the PAI group exhibited significantly lower levels of CRP, IL-1β, and IL-6 as well as a lower ERS and VAS score compared with the control group (P < .05), while the Harris hip score was significantly higher postoperatively in the PAI group (P < .05).Conclusion:Multimodal drug PAI can alleviate the inflammatory response and enhance hip function recovery after hip arthroplasty in elderly patients with osteoporotic femoral neck fractures.     

Is intraoperative corticosteroid a good choice for postoperative pain relief in total joint arthroplasty? A meta-analysis of 11 randomized controlled trials

Background:Effective postoperative analgesia is of great significance for postoperative rehabilitation. This meta-analysis aimed to investigate the efficacy of corticosteroid on pain following total joint arthroplasty.Method:PubMed (1996–December 2020), Embase (1996–December 2020), and the Cochrane Library (CENTRAL, December 2020) were searched and a total of 11 randomized controlled trials met our inclusion criteria.Results:Eleven randomized controlled trials met the inclusion criteria. Pooled data indicated the corticosteroid group was effective compared to the control group in terms of the visual analogue scale at rest (P < .05) and movement (P < .05), the total morphine equivalent consumption (P < .05), and the length of stay (P < .05), without increasing the risk of periprosthetic joint infection (P = .74) and the length of stay (P = .32).Conclusions:Compared to the control group, intraoperative corticosteroid was benefit to the pain management in total joint arthroplasty.     

Displaced proximal humerus fractures treated with ORIF via the deltoid interfascicular approach vs the deltopectoral approach: A prospective case-control study

Background:The purpose of this study was to evaluate the clinical outcomes and complications of displaced proximal humeral fractures treated with proximal humeral internal locking system (PHILOS) plate fixation via a deltoid interfascicular (DI) vs a deltopectoral (DP) approach.Methods:This prospective case-control study was conducted with patients admitted to our hospital from May 2015 to June 2018 who suffered from unilateral displaced proximal humerus fractures. Patients were treated with PHILOS plate fixation via a DI (DI group) or DP approach (DP group). The clinical outcomes and complication data were collected for comparison between the 2 groups. The patients were followed up at 3, 6, and 12 months; and every 6 months thereafter. The patients’ functional recoveries were evaluated according to the normalized Constant-Murley score, range of motion of the shoulder (flexion, abduction, external/internal rotation) and disabilities of the arm, shoulder and hand score.Results:A total of 77 patients, followed for an average of 15 ± 2.2months (range, 12–21), were enrolled (36 in DI group and 41 in DP group) for final analysis. No significant differences in age, sex, affected side, fracture type, injury mechanism or time from injury to operation were found between the 2 groups (all P > .05). The incision length, intra-operative blood loss, and duration of operation in the DI group were significantly less than those in the DP group, respectively (all P < .05). The functional outcomes assessed by the normalized Constant-Murley score and range of motion of flexion and internal rotation in the DI group were superior to those in the DP group at 3 and 6months after the operation (P < .05); however, no significant differences were observed at the 12-month and subsequent follow-ups (all P > .05). There was no significant difference in the range of shoulder external rotation and abduction during the postoperative follow-ups (P > .05). At the last follow-up, the mean disabilities of the arm, shoulder, and hand score was 14.0 (6.6) points in the DI group and 14.4 (6.9) points in the DP group (P = .793). Complications occurred in 1 patient in the DI group and 8 patients in the DP group (P = .049).Conclusion:The current study demonstrates that DI approach is a safe and effective alternative for the treatment displaced proximal humerus fractures. The DI approach rather than DP approach was recommended when lateral and posterior exposure of the proximal humerus is required, especially when fixed with PHILOS plate.     

Study on the effect of percutaneous intervertebral foraminoscopic discectomy in the treatment of lumbar disc herniation

This study explored the effect of percutaneous intervertebral foraminoscopic discectomy (PIFD) in the treatment of lumbar disc herniation (LDH).This retrospective study collected a total of 88 patient cases for inclusion. Epidemiological and clinical data of patients with LDH at the First Affiliated Hospital of Jiamusi University between May 2017 and January 2020 were retrospectively analyzed. Of those, 44 patients received PIFD and were allocated to an intervention group. The other 44 patients administrated fenestration discectomy (FD), and were assigned to a control group. We compared surgery time (minute), incision length (cm), duration of hospital stay after surgery (day), pain intensity (as checked by Visual Analogue Scale (VAS), health-related quality of life (as examined by Oswestry Disability Index, ODI), and complications between 2 groups.There were not significant differences in surgery time (minute) (P = .56), VAS (P = .33) and ODI (P = .46) after surgery between 2 groups. However, there were significant differences in incision size (cm) (P < .01) and length of hospital stay (day) (P < .01) after surgery between 2 groups. When compared before the surgery, patients in both groups had significant improvements in VAS (P < .01) and ODI (P < .01) after the surgery. Moreover, both groups had similar safety profiles (P > .05).The findings of this study showed that both PIFD and FD benefit patients with LDH. However, PIFD can benefit patients more than FD in the incision size and duration of hospital stay after surgery.     

The clinical efficacy of external application of mirabilite and rhubarb combined with intrathoracic chemotherapy in treating malignant pleural effusion: A prospective,randomized, controlled clinical trial

Background:Malignant pleural effusion (MPE) is one of the commonest causes of an exudative pleural effusion. Breathlessness, dyspnea and other symptoms often seriously distress and affect the quality of life. The external application of mirabilite and rhubarb (EAMR) combined with intrathoracic infusion of cisplatin, as an alternative treatment for MPE, is popular in China. The study aims to assess its effectiveness and safety combined with intrathoracic chemotherapy.Methods:This study is a prospective, randomized controlled clinical trial. Patient visits were performed at baseline and days 14 and 28 after treatment. Clinical outcomes were measured after chest drain placement using the criterion of efficacy refer to WHO standard, and QLQ-C30 questionnaire.Results:Database records of patients treated in our institution for MPE between October, 2016 and March, 2019. The study included 84 eligible patients. They were categorized with a randomization schedule into treatment group (N = 42) and control group (N = 42). There is statistical significance in the comparison of the total effective rate between these 2 groups (66.67% vs 54.76%, P < .05). Furthermore, there is statistical significance in the comparison of items of Physical (1.95 ± 0.50 vs 2.19 ± 0.58%, P < .05), Pain (1.98 ± 0.42 vs 2.07 ± 0.32, P < .05), and Global Health (1.23 ± 0.64 vs 1.13 ± 0.23%, P < .05) between these 2 groups. None of the patients had adverse reactions such as skin allergy and chest tightness.Conclusions:The total effective rate of treatment group using extra external application of mirabilite rhubarb powder is significantly higher than that of control group. The improvement of patients’ clinical symptoms is greater in treatment group and no adverse reactions is found. Therefore, external application of mirabilite and rhubarb combined with intrathoracic infusion of cisplatin is an effective method for the treatment of MPE, which is worth popularizing.     

Effects of a preoperative forced-air warming system for patients undergoing video-assisted thoracic surgery: A randomized controlled trial

Background:The incidence of intraoperative hypothermia is still high despite the proposal of different preventive measures during thoracoscopic surgery. This randomized control study evaluated the effects of 30-minute prewarming combined with a forced-air warming system during surgery to prevent intraoperative hypothermia in patients undergoing video-assisted thoracic surgery under general anesthesia combined with erector spinae nerve block.Methods:Ninety-eight patients were randomly and equally allocated to prewarming or warming groups (n = 49 each). The primary outcome was the incidence of intraoperative hypothermia. Secondary outcomes were core temperature, irrigation and infused fluid, estimated blood loss, urine output, type of surgery, intraoperative anesthetic dosage, hemodynamics, recovery time, the incidence of postoperative shivering, thermal comfort, postoperative sufentanil consumption and pain intensity, patient satisfaction, and adverse events.Results:The incidence of intraoperative hypothermia was significantly lower in the prewarming group than the warming group (12.24% vs 32.65%, P = .015). Core temperature showed the highest decrease 30 minutes after surgery start in both groups; however, the rate was lower in the prewarming than in the warming group (0.31 ± 0.04°C vs 0.42 ± 0.06°C, P < .05). Compared with the warming group, higher core temperatures were recorded for patients in the prewarming group from T1 to T6 (P < .05). Significantly fewer patients with mild hypothermia were in the prewarming group (5 vs 13, P = .037) and recovery time was significantly reduced in the prewarming group (P < .05). Although the incidence of postoperative shivering was lower in the prewarming group, it was not statistically significant (6.12% vs 18.37%, P = .064). Likewise, the shivering severity was similar for both groups. Thermal comfort was significantly increased in the prewarming group, although patient satisfaction was comparable between the 2 groups (P > .05). No adverse events occurred associated with the forced-air warming system. Both groups shared similar baseline demographics, type of surgery, total irrigation fluid, total infused fluid, estimated blood loss, urine output, intraoperative anesthetic dosage, hemodynamics, duration of anesthesia and operation time, postoperative sufentanil consumption, and pain intensity.Conclusion:In patients undergoing video-assisted thoracic surgery, prewarming for 30 minutes before the induction of anesthesia combined with a forced-air warming system may improve perioperative core temperature and the thermal comfort, although the incidence of postoperative shivering and severity did not improve.     

Preemptive analgesia using selective cyclooxygenase-2 inhibitors alleviates postoperative pain in patients undergoing total knee arthroplasty: A protocol for PRISMA guided meta-analysis of randomized controlled trials

Background:The postoperative pain associated with total knee arthroplasty (TKA) is severe for most patients. The analgesic efficacy and safety of preoperative use of selective cyclooxygenase-2 (COX-2) inhibitors for patients undergoing TKA are unclear.Objectives:We conducted a systematic review and meta-analysis to assess whether the use of selective COX-2 inhibitors before TKA decreases the postoperative pain intensity.Methods:Data sources: The PubMed, Embase, EBSCO, Web of Science, and Cochrane Controlled Register of Trials databases from inception to January 2020.Study eligibility criteria:All randomized controlled trials (RCTs) in which the intervention treatment was preoperative selective COX-2 vs placebo in patients undergoing TKA and that had at least one of the quantitative outcomes mentioned in the following section of this paper were included. Letters, review articles, case reports, editorials, animal experimental studies, and retrospective studies were excluded.Interventions:All RCTs in which the intervention treatment was preoperative selective COX-2 vs placebo in patients undergoing TKA.Study appraisal and synthesis methods:The quality of the RCTs was quantified using the Newcastle–Ottawa quality assessment scale. RevMan 5.3 software was used for the meta-analysis.Results:Six RCTs that had enrolled a total of 574 patients were included in the meta-analysis. The visual analog scale pain score at rest was significantly different between the experimental group and control group at 24 hours (P < .05) and 72 hours (P < .05) postoperatively. The experimental group exhibited a significant visual analog scale pain score during flexion at 24 hours postoperatively (P < .05), and it was not different at 72 hours postoperatively (P = .08). There was a significant difference in opioid consumption (P < .05), but there was no difference in the operation time (P = .24) or postoperative nausea/vomiting (P = .64) between the groups.Conclusion:The efficacy of preoperative administration of selective COX-2 inhibitors to reduce postoperative pain and opioid consumption after TKA is validated.Systematic review registration number:INPLASY202090101     

Effect of Ma Yinglong Shexiang hemorrhoids cream combined with pearl powder on the pain and complications of severe pressure ulcer patients

Objective:The aim of this study was to investigate the effect of Ma Yinglong Shexiang Hemorrhoids Cream combined with pearl powder on pain and complications in patients with severe pressure ulcers.Methods:One hundred seventeen patients with severe pressure ulcers hospitalized and treated in our hospital (January 2019--December 2019) were divided into Ma Yinglong Musk Hemorrhoid Cream Group (MY Group), Pearl Powder Group (PP Group), and combination with Ma Yinglong Musk Hemorrhoid Cream and Pearl Powder Group (MP group), 39 patients in each group. There was no significant difference in the general data of patients in MY group, PP group, and MP group. By analyzing the differences in clinical efficacy, secondary effects, scar incidence, pain, and clinical indicators of patients in the MY group, PP group, and MP group, the effects of Mayinglong Shexiang Hemorrhoid Cream combined with pearl powder in the treatment of pain and complications in patients with severe pressure ulcers were explored.Results:After treatment, compared with the MY group and the PP group, the MP group had a higher clinical efficacy than the MY group and the PP group. Compared with MY group and PP group, the healing time, dressing change times, and dressing change time of MP group were better than MY group (P < .05). After treatment, the VAS score and incidence of secondary effects of the MP group was significantly lower than that of the MY group and PP group (P < .05). The incidence and area of scar formation in the MP group were lower than those in the MY group and the PP group (P < .05).Conclusion:Compared with Ma Yinglong Musk Hemorrhoid Cream or Pearl Powder, combination of Ma Yinglong Musk Hemorrhoid Cream and Pearl Powder are more effective in treating severe pressure ulcer patients, and can significantly reduce the pain in the affected area and reduce the occurrence of complications.
