Preoperative pain catastrophizing affects pain outcome after total knee arthroplasty

BackgroundsPreoperative widespread pain sensitization or pain catastrophizing could be associated with chronic pain after total knee arthroplasty (TKA). The aim of the present study was to examine the association between postoperative pain in patients undergoing TKA and preoperative factors, including patient characteristics and preoperative central sensitization as well as pain catastrophizing.MethodsPreoperative TKA patients were evaluated using the Central Sensitization Inventory (CSI)-9 and Pain Catastrophizing Scale (PCS). Postoperative knee pain was evaluated using a numerical rating scale (NRS) 6 months after TKA. Statistical analyses were performed to assess the relationship between NRS 6 months after TKA and preoperative factors, including patient characteristics, CSI-9, and PCS.ResultsWe enrolled 58 consecutive patients with osteoarthritis who underwent TKA. Using cutoff of 14, postoperative NRS was higher in the patients with ≥14 than the patients with <14 in CSI (p = 0.025). Postoperative NRS was higher in the patients with ≥30 than the patients with <30 in PCS (p = 0.043). Preoperative PCS was a significant risk factor of postoperative pain using a multivariate analysis.ConclusionsSurgeon should recognize preoperative PCS could affect postoperative pain 6 months after TKA.     

Comparison of the postoperative analgesic efficacies of intravenous acetaminophen and fascia iliaca compartment block in hip fracture surgery: A randomised controlled trial

BackgroundManaging pain during movement after hip fracture surgery is important for achieving earlier hip mobilisation and for preventing postoperative complications. In the present study, we tested the hypothesis that the fascia iliaca compartment block (FICB) would improve postoperative pain on movement compared with intravenous acetaminophen.MethodsIn this prospective, randomised, controlled, parallel trial, patients were assigned to either the intravenous acetaminophen or the ultrasound-guided FICB group. Visual analog scale (VAS) pain scores were evaluated at 6, 9, 12, 18, 24 h, 2 days, and 7 days postoperatively. The primary outcome was VAS scores on movement at 24 h after surgery. The secondary outcomes were VAS scores on movement at the other time points, VAS scores at rest, the total number of rescue analgesics required and incidence of delirium during the first 24 h postoperatively, potential drug or block-related complications, and the time to first standing.ResultsVAS scores on movement at 24 h after surgery were significantly lower in the FICB group than in the intravenous acetaminophen group [median (the 25th to 75th percentiles), 20 (10–30) vs 40 (30–53); P < 0.01]. The VAS scores on movement at any other time point and the scores at rest at 12 h after surgery were also significantly lower in the FICB group than in the intravenous acetaminophen group. The two groups did not differ in terms of the total number of rescue analgesics required or the incidence of delirium during the first 24 h postoperatively; complications; or the time to first standing.ConclusionsFICB improved postoperative pain on movement compared with intravenous acetaminophen without increasing the complication rate. However, the total number of rescue analgesics required and the time to first standing were not significantly different between the two groups.     

Postoperative continuous-flow cryocompression therapy in the acute recovery phase of hip fracture surgery—A randomized controlled clinical trial

BackgroundThe acute recovery phase after hip fracture surgery is often complicated by severe pain, postoperative blood loss with subsequent transfusion, and delirium. Prevalent comorbidity in hip fracture patients limit the use of opioid-based analgesic therapies, yielding a high risk for inferior pain treatment. Postoperative cryotherapy is suggested to provide an analgesic effect, and to reduce postoperative blood loss. In this prospective, open-label, parallel, multicentre, randomized controlled, clinical trial, we aimed to determine the efficacy of continuous-flow cryocompression therapy (CFCT) in the acute recovery phase after hip fracture surgery.MethodsPatients with an intra or extracapsular hip fracture scheduled for surgery were included. Subjects were allocated to receive postoperative CFCT or usual care. The primary endpoint was numeric rating scale (NRS) pain the first 72 postoperative hours. Secondly, analgesic use; postoperative haemoglobin change and transfusion incidence; functional outcome; length of stay; delirium incidence; location of rehabilitation; patient-reported health outcome; complications and feasibility were assessed.ResultsSixty-one subjects in the control group, and 64 subjects in the CFCT group were analysed. Within the CFCT group, post treatment NRS pain declined 0.31 (p = 0.07) at 24 h, 0.28 (p = 0.07) at 48 h, and 0.47 (p = 0.002) at 72 h relative to pre treatment NRS pain. Sensitivity analysis at 72 h showed that NRS pain was 0.92 lower in the CFCT group when compared to the control group (1.50 vs. 2.42; p = 0.03). Postoperative analgesic use was comparable between groups. Between postoperative day one and three haemoglobin declined 0.29 mmol/l in the CFCT group and 0.51 mmol/l in controls (p = 0.06), and transfusion incidence was comparable. The timed up and go test and length of stay were also comparable between both groups. Complications, amongst delirium and cryotherapy-related adverse events were not statistically significantly different. Discharge locations did not differ between groups. At outpatient follow-up subjects did not differ in patient-reported health outcome scores. Subjects rated CFCT satisfaction with an average of 7.1 out of 10 points.ConclusionsNo evidence was recorded to suggest that CFCT has an added value in the acute recovery phase after hip fracture surgery. If patients complete the CFCT treatment schedule, a mild analgesic effect is observed at 72 h.     

乳腺癌患者术前超声引导下胸椎旁神经阻滞与术后慢性疼痛的相关性

目的采用倾向性评分匹配法(PSM)评估术前超声引导下胸椎旁神经阻滞(TPVB)与术后1年以上乳腺癌患者术后慢性疼痛(CPSP)的相关性。方法回顾性收集2018年1月至2019年3月全麻下择期乳腺癌手术女性患者的临床资料,ASAⅠ—Ⅲ级。根据是否接受术前超声引导下TPVB将患者分为两组:TPVB联合全麻组(TG组)和单纯全麻组(G组)。采用PSM法对患者资料进行匹配,对患者进行电话随访,评估CPSP的发生情况,并采用ID-Pain量表评估神经病理性疼痛(NP)。结果 PSM匹配后两组各纳入患者148例。TG组CPSP发生率为64例(43.2%),G组CPSP发生率为50例(33.8%),两组差异无统计学意义。TG组中重度疼痛发生率低于G组,NP发生率高于G组,但差异无统计学意义。TG组CPSP的中位NRS评分为2 (1～3)分,G组为2 (1～4)分,两组差异无统计学意义。结论术前超声引导下TPVB与乳腺癌术后1年以上患者CPSP发生率降低无明显相关性。     

Mutaciones y variaciones estructurales en el gen catecol-O-metiltransferasa de los pacientes que exhiben dolor quirúrgico persistente crónico

ObjectivesMutations in the exon 4 of the COMT gene are associated with chronic persistent surgical pain (CPSP). Especially COMT mutated allele G472A (Val158Met) associated with CPSP patients is reported in different ethnic population. The purpose of this study is to evaluate the prevalence of genetic mutations and structural variations in exon 4 of COMT that can be related to the appearance of CPSP in patients under sternotomy.Materials and methodsOne hundred patients with American Society of Anesthesiologists (ASA) physical status grades i, ii and iii, who underwent sternotomy procedures, were selected to assess the development and magnitude of the CPSP evaluated with pain questionaries’ at the end of three months after surgery. This was correlated with COMT allele presence. The exon 4 of COMT gene (that contains the G472A allele) was studied. The polymerase chain reaction (PCR) products were sequenced and mutated sequences were deposited in GenBank®. The structural analysis of COMT was performed using ProCheck® and distortions of three-dimensional tertiary structural orientation was evaluated with root-mean-square deviation (RMSD) score.ResultsGenetic analysis carried out through PCR showed 220 bp amplicons. The 25% of patients with CPSP showed a Numeric Rating Scale (NRS) > 4 pain score. The 20% of these patients have known Val158Met mutation, 5% of patients showed novel mutations c.382C>G, c.383G>C, p.(Arg128Ala). The mutations in COMT gene contributed major structural variations in COMT leading to the formation of inactive COMT that correlates with CPSP.ConclusionThe results of the present study showed that both novel and previously reported mutations in COMT gene has strong association with CPSP.     

Patient-Controlled Analgesia After Cardiac Surgery With Median Sternotomy: No Advantages of Hydromorphone When Compared to Morphine

ObjectivesTo compare the efficacy, safety, and side effects of hydromorphone and morphine administered as patient-controlled analgesia (PCA) for postoperative pain therapy after cardiac surgery with median sternotomy.DesignA retrospective analysis of data from 2 prospective, single-blinded, randomized trials.SettingA single-center intensive care unit at a university hospital.ParticipantsForty-one adult patients undergoing cardiac surgery with median sternotomy.InterventionsPostoperative pain therapy at the intensive care unit was performed by PCA with intravenously administered bolus doses of 0.2 mg of hydromorphone (n = 21) or 2 mg of morphine (n = 20).Measurements and Main ResultsPain at rest and under deep inspiration regularly was assessed using the 11-point numerical rating scale (NRS). Blood pressure, heart rate, cardiac output, oxygen saturation, and respiratory rate were monitored, and adverse events were registered. The median (range) NRS rating at rest was 1.5 (0-5) after hydromorphone and 0.5 (0-5) after morphine, respectively (p = 0.41). The median NRS rating under deep inspiration was 3 (0-6) after hydromorphone and 4 (0-7) after morphine, respectively (p = 0.074). The dose ratio of morphine to hydromorphone during PCA was 5.7 (95% confidence interval: 2.9-7.6). Hemodynamics and respiration were stable and did not differ significantly. Postoperative nausea and vomiting were the most frequent adverse events, which were observed in 29% of the patients after hydromorphone and in 35% after morphine, respectively (p = 0.74).ConclusionsThere were no significant differences in analgesic efficacy and safety between hydromorphone and morphine when used for postoperative pain therapy with PCA after cardiac surgery with median sternotomy.     

The comparison of postoperative analgesic efficacy of three-in-one-block versus fascia-iliaca blocks following femoral fracture orthopedics surgical procedures under spinal anesthesia,Gondar, Ethiopia, 2021: A prospective cohort study

Introduction

Femoral bone fracture is the predominant, lower limb orthopedic surgery that is associated with severe acute and persistent chronic pain that needs better postoperative pain management. Untreated postoperative pain results inability to do physiotherapy resulting in stiffens of joints and immobility. This study aimed to compare the postoperative analgesic efficacy of three-in-one-block versus fascia iliaca block in patients who underwent surgically treated femoral fractured patients under spinal anesthesia.

Methods

A prospective cohort study was conducted on 110 elective surgically treated femoral fractured orthopedic patients from January to October 2021. Data were entered into epi-data 4.4.2 and imported into a statistical package of social science version 22 for analysis. Shapiro–Wilk normality test was used to check the normality of the data and normally distributed data were analyzed using Student’s independent t-test, whereas non-normally distributed variables were analyzed with Mann–Whitney U-test. The comparisons of categorical parameters were analyzed using the chi-square test and Fisher’s exact test. Finally p-value < 0.05 was declared to be statistically significant.

Result

The median and interquartile range of the postoperative numerical rating scale at rest and on movement was significantly less in three-in-one-block (3IN1B) as compared with fascia-iliaca block (FICB). But at 30 min no significantly different between the two pain management modalities. Moreover, the meantime to seek the first request of analgesia was significantly prolonged in 3IN1B compared with FICB. Regarding the total analgesic consumption, the mean total tramadol consumption was 97. 27 ± 53. 07 and 180 ± 72.96 (p < 0.001) and Diclofenac 53.18 ± 29.28 and 72 ± 43.54 (p < 0. 001) in 3IN1 and FICB, respectively.

Conclusion

The present study concludes that three-in-one-block provides more effective analgesia, reduced postoperative analgesic requirements, and prolonged first analgesics requests compared with fascia iliaca block, and Landmark technique fascia-iliaca block (FICB) is an alternative pain management modality in a resource-limited setting.

     

Acute pain after total hip arthroplasty does not predict the development of chronic postsurgical pain 6 months later

Purpose  

Much remains unknown about the relationship between acute postoperative pain and the development of pathologic chronic postsurgical pain (CPSP). The purpose of this project was to identify the extent to which maximum pain scores on movement over the first two days after total hip arthroplasty predicted the presence of chronic pain 6 months later after controlling for potentially important covariates.     

The outcome of conservative treatment of fifth metatarsal diaphyseal fractures

IntroductionThe fifth metatarsal diaphyseal fracture is a common fracture. However, clear consensus about the treatment is lacking. Unlike the avulsion fracture or Jones’ fracture, literature available on the treatment and long-term outcome of the diaphyseal fracture is scarce.The purpose of this study is to demonstrate a substantial number of conservatively treated patients with persistent pain and to evaluate metatarsal shortening and displacement within this group.MethodsIn this retrospective study, 106 patients who had experienced a fifth metatarsal diaphyseal fracture were included and evaluated. The minimum follow-up period was three months. FAAM, AOFAS and NRS scores were used as outcome measurements for function and pain. Length and displacement were analysed on plain X-rays.ResultsAt least 11% of the patients who received conservative treatment for their fifth metatarsal diaphyseal fracture had persistent pain at least 3 months after initiation of conservative treatment. No relationship has been found between the length of the fifth metatarsal and the FAAM (r( Petrisor et al., 2006) 2 = 0,051), AOFAS (r( Petrisor et al., 2006) 2 = 0,009) and NRS (r( Petrisor et al., 2006) 2 = 0,001). Furthermore, there was no association between patients with a shorter fifth metatarsal and FAAM, AOFAS, NRS, displacement and BMI.Discussion and conclusionThe finding of persistent pain in at least 11% of all patients at long-term follow-up confirms our hypothesis on long-term symptoms. However, the results suggest that these persistent symptoms are not related to metatarsal shortening or displacement.     

Serratus anterior plane block reduces the prevalence of chronic postsurgical pain after modified radical mastectomy: A randomized controlled trial

Study objectiveTo determine whether ultrasound-guided serratus anterior plane block (SAPB) is associated with decreased prevalence of chronic postsurgical pain (CPSP) after modified radical mastectomy.DesignRandomized, double-blind, placebo-controlled study.SettingUniversity hospital.PatientsWe enrolled 198 patients aged 18–65 years with American Society of Anesthesiologists physical status I to II, undergoing unilateral modified radical mastectomy.InterventionsPatients were randomly allocated to receive SAPB with 30 ml of 0.5% ropivacaine (SAPB group) or 0.9% normal saline (Control group).MeasurementsThe primary outcome was the prevalence of CPSP three months after surgery. Secondary outcomes were area under the curve of the numeric rating scale pain scores over 24 h, postoperative 24-h morphine consumption, quality of recovery, length of post-anesthesia care unit stay, postoperative nausea and vomiting, dizziness, SAPB-related adverse events, the prevalence of CPSP at six months, and pain-related function at three and six months.Main resultsPreoperative SAPB with 0.5% ropivacaine reduced the prevalence of CPSP at three postoperative months from 46/89 (51.7%) to 22/90 (25.6%), relative risk (95% confidence interval): 0.47 (0.31–0.72), P < 0.001. The prevalence of CPSP was reduced at six months from 37/89 (41.6%) to 17/90 (18.9%), relative risk (95% confidence interval): 0.72 (0.58–0.88), P = 0.001. Moreover, SAPB decreased the area under the curve of the numeric rating scale pain scores over 24 h, shortened the length of post-anesthesia care unit stay, reduced postoperative 24-h morphine consumption and the occurrence of postoperative nausea and vomiting, and improved quality of recovery and patient satisfaction, with P < 0.05 for all. No SAPB-related complications occurred.ConclusionsPreoperative SAPB with ropivacaine improved acute postoperative analgesia and quality of recovery and decreased the prevalence of CPSP at three and six months after modified radical mastectomy.     

Optimizing Rapid Recovery After Anterior Hip Arthroplasty Surgery: A Comparative Study of Fascia Iliaca Compartment Block and Local Infiltration Analgesia

BackgroundMultimodal pain therapy combining analgesics, local infiltration analgesia (LIA) and peripheral nerve blocks, such as fascia iliaca compartment block (FICB), can improve postoperative pain, nausea and vomiting (PONV) and ambulation in patients undergoing total hip arthroplasty (THA). We hypothesized that addition of FICB would decrease opioid requirements and length of stay (LOS) but could create a motor block.MethodsThis is a single center, prospective, blinded randomized controlled study of 152 patients undergoing elective THA via direct anterior approach from October 2019 till August 2021. Three patient groups were defined: patients receiving only spinal anesthesia (control group, n = 53); spinal anesthesia with LIA perioperatively (n = 50); and spinal anesthesia with FICB on the recovery unit (n = 49). Outcome measures consisted of postoperative pain scores, PONV, length of hospital stay, opioid requirements and mobility.ResultsOverall pain scores were low for all patient groups, with a lower pain score for LIA in comparison to the control group until 4 hours postoperatively (P < .05). Length of hospital stay, postoperative pain, nausea and vomiting (PONV) scores and quadriceps muscle strength did not differ significantly between groups. The control group showed higher scores at 12 hours postoperatively in comparison to FICB regarding rehabilitation potential, use of walking aids and activities of daily living (P < .05), but all groups reached the same endpoint 48 hours postoperatively. The LIA and FICB groups required less opioids until 24 hours postoperatively.ConclusionLIA is a beneficial adjuvant therapy to spinal anesthesia in THA patients as it may decrease pain scores and the need for opioid consumption. Adjuvant FICB only provided lower opioid requirements.

结论 肛肠手术CPSP发生率较低,术前疼痛、术前贫血、术后出血、术后睡眠障碍以及术后7 d VAS疼痛评分>3分是发生肛肠手术CPSP的危险因素。     

Patients’ first-year adherence to different anti-osteoporotic therapy after hip fractures

BackgroundOsteoporosis medication treatment is recommended after geriatric fractures. However, the percentage of patients receiving anti-osteoporotic treatment after a hip fracture is extremely low.ObjectivesThe aim of this study was to evaluate the adherence to different anti-osteoporotic medications in elderly patients following hip fracture.MethodsThis retrospective study included 520 patients treated with osteoporotic hip fracture between March 2014 and June 2019. The patients were asked to choose the medication for osteoporosis treatment at discharge. Adherence was monitored by follow-up visits to the outpatient clinic at 1 year following surgery.ResultsOf 520 patients with baseline data, osteoporosis medications were prescribed to 250 (48.1%) patients. Of these patients, 110 (44.0%) took subcutaneous denosumab, 69 (27.6%) took oral selective estrogen receptor modulator, 55 (21.0%) took intravenous bisphosphonate. At 12 months, we followed up 178 (71.2%) patients. Of those prescribed a bone protection medication, only 85 patients (34.0%) reported still taking their medication 1 year later. The rate of adherence to 6-month subcutaneous denosumab injection was significantly higher than that for quarterly intravenous bisphosphonates (p = 0.024) or daily oral tablets (p = 0.028). Conclusions: This study revealed patients' adherence for osteoporosis treatments after hip fracture. 6-month subcutaneous denosumab injection was preferred over 3-month intravenous injection or daily oral tablets in this elderly population and exhibited significant lower discontinuation rates. However, because of the limited power of the study, further research is required to identify the reasons behind non-adherence and to improve adherence to anti-osteoporosis medications.     

High Pre-Operative Expectations Precede Both Unfulfilled Expectations and Clinical Improvement After Total Hip and Total Knee Replacement

BackgroundThis prospective study aimed to examine whether patients’ and physicians’ outcome expectations were related to subjective (ie, fulfillment of expectations) and objective outcomes (ie, change in pain and function) in hip and knee arthroplasty patients up to 6 months post-surgery.MethodsPatients’ (N = 395) and physicians’ outcome expectations were examined 1 week post-consultation. Patients’ post-operative functional status and the extent of fulfillment of expectations were examined 5 weeks, 3 months, and 6 months post-surgery. Patients and physicians completed the Hospital for Special Surgery Hip/Knee Replacement (Fulfillment) Expectations Survey. Patients completed the Hip/Knee injury and Osteoarthritis Outcome Score. Linear regression analyses were performed to examine the relationship between physicians’ expectations and patients’ change in pain and function and extent of fulfillment of expectations, and a possible mediated effect of patients’ pre-operative expectations.ResultsPatients’ high expectations were consistently associated with better objective outcomes (ie, change in pain and function). Yet, high expectations in patients were also negatively related to subjective outcomes (ie, the extent of fulfillment of expectations). Physicians’ expectations were only positively associated with objective improvement in knee patients, and not in hip patients. Additionally, knee patients’ expectations partly mediated the relationship between physicians’ expectations and change in pain and function, 6 months post-surgery.ConclusionAlthough patients’ high expectations were associated with better objective outcomes, improvement was still less than patients expected. Thus, patients often have too high expectations of outcomes of surgery. In addition, physicians were able to influence patients’ expectations and to change experienced knee patients’ outcomes.     

Fascia-iliaca compartment block vs intra-articular hip injection for preoperative pain management in intracapsular hip fractures: A blind,randomized, controlled trial

BackgroundThe aim of this study was to compare the fascia-iliaca compartment block and the intra-articular hip injection in terms of pain management and the need for additional systemic analgesia in the preoperative phase of intracapsular hip fractures.MethodsPatients >65 years old with an intracapsular hip fracture were randomized in this prospective, blind, controlled, parallel trial in a Level-I trauma center. Patients were randomly assigned to receive either the fascia-iliaca compartment block (cohort FICB) or the intra-articular hip injection (cohort IAHI) upon admission to the emergency department. The primary outcome was pain relief at 20 min, 12 h, 24 h and 48 h after the regional anesthesia, both at rest and during internal rotation of the fractured limb. The Numeric Rating Scale was used. Residual pain was managed with the same protocol in all patients. Additional analgesic drug administration during the 48 h from admission was recorded.ResultsA total of 120 patients with comparable baseline characteristics were analyzed in this study: the FICB group consisted of 70 subjects, while the IAHI group consisted of 50 subjects.Pain was significantly lower in the IAHI group during movement of the fractured limb at 20 min (p < 0.05), 12 h (p < 0.05), 24 h (p < 0.05) and 48 h (p < 0.05).In the FICB cohort 72.9% of patients needed to take oxycodone, in contrast to 28.6% of the IAHI cohort (p < 0.05). In the FICB cohort 14.09 ± 11.57 mg of oxycodone was administered, while in the IAHI cohort 4.38 ± 7.63 mg (p < 0.05). No adverse events related to either technique were recorded.ConclusionsIntra-articular hip injection provides better pre-operatory pain management in elder patients with intracapsular hip fractures compared to the fascia-iliaca compartment block. It also reduced the need for supplementary systemic analgesia.Level of EvidenceTherapeutic Level I.     

Do-Not-Resuscitate status is an independent risk factor for medical complications and mortality among geriatric patients sustaining hip fractures

BackgroundThe purpose of this study was to compare outcomes after hip fracture surgery between DNR/DNI and full code cohorts to determine whether DNR/DNI status is an independent predictor of complications and mortality within one year. A significant number of geriatric hip fracture patients carry a code status designation of DNR/DNI (Do-Not-Resuscitate/Do-Not-Intubate). There is limited data addressing how this designation may influence prognosis.MethodsA retrospective chart review of all geriatric hip fractures treated between 2002 and 2017 at a single level-I academic trauma center was performed. 434 patients were eligible for this study with 209 in the DNR/DNI cohort and 225 in the full code cohort. The independent variable was code-status and dependent variables included patient demographics, surgery performed, American Society of Anesthesiologists, score, Charlson Comorbidity Index, significant medical and surgical complications within one year of surgery, duration of follow-up by an orthopaedic surgeon, duration of follow-up by any physician, and mortality within 1 year of surgery. One-year complication rates were compared, and multiple logistic regression analyses were performed to analyze the relationship between independent and dependent variables.ResultsThe DNR/DNI cohort experienced significantly more surgical complications compared to the full code cohort (14.8% vs 7.6%, p = 0.024). There was a significantly higher rate of medical complications and mortality in the DNR/DNI cohort (57.9% vs 36%, p < 0.001 and 19.1% vs 3.1%, p = 0.037, respectively). In the regression analysis, DNR/DNI status was an independent predictor of a medical complication (odds ratio 2.33, p = 0.004) and one-year mortality (odds ratio 9.69, p < 0.001), but was not for a surgical complication (OR 1.95, p = 0.892).ConclusionsIn our analysis, DNR/DNI code status was an independent risk factor for postoperative medical complications and mortality within one year following hip fracture surgery. The results of our study highlight the need to recognize the relationship between DNR/DNI designation and medical frailty when treating hip fractures in the elderly population.     

Fascia iliaca block prophylaxis for hip fracture patients at risk for delirium: a randomized placebo-controlled study

Background  

Recent studies have indicated that unmanaged pain, both acute and chronic, can affect mental status and might precipitate delirium, especially in elderly patients with hip fractures. The aim of this study was to assess the effectiveness of fascia iliaca compartment block (FICB) for prevention of perioperative delirium in hip surgery patients who were at intermediate or high risk for this complication.     

Ultrasound-guided erector spinae plane block for postoperative analgesia in patients undergoing open radical prostatectomy: A randomized,placebo-controlled trial

Study objectiveThe aim of this study was to evaluate the effect of ultrasound-guided erector spinae plane (ESP) block on postoperative pain in radical prostatectomy, which leads to both visceral and somatic pain.DesignProspective, randomized, placebo controlled, double-blinded.SettingUniversity hospital.PatientsA total of ASA I-III, 50 patients aged 18–65 who were scheduled for elective open radical prostatectomy surgery.InterventionsPatients were randomly allocated to receive an ultrasound-guided ESP block, with either local anesthetic (10 mL of 1% lidocaine +10 mL of 0.5% bupivacaine) or placebo bilaterally.MeasurementsThe primary outcome was morphine consumption in the first 24 h after surgery. The secondary outcomes were NRS pain scores at rest and coughing, intraoperative remifentanil consumption and need for rescue analgesic during the first 24 h after surgery.Main resultsBoth NRS scores for post-anesthesia care unit and NRS_rest scores for 1st hours were lower in Group ESPB (p < 0.001 and p = 0.033, respectively). Cumulative morphine consumption at 24 h post-surgery was similar between the groups (p = 0.447). Rescue analgesic requirement was higher in the placebo injection group than in the ESPB group at the 1st postoperative hour (p = 0.002).ConclusionsIn open radical prostatectomies, except for the first hour, ESP block is ineffective for pain scores and on morphine consumption compared to the placebo injection group in the postoperative period.
