Intravenous lidocaine infusion facilitates acute rehabilitation after laparoscopic colectomy

BACKGROUND: Intravenous infusion of lidocaine decreases postoperative pain and speeds the return of bowel function. The authors therefore tested the hypothesis that perioperative lidocaine infusion facilitates acute rehabilitation protocol in patients undergoing laparoscopic colectomy. METHODS: Forty patients scheduled to undergo laparoscopic colectomy were randomly allocated to receive intravenous lidocaine (bolus injection of 1.5 mg/kg lidocaine at induction of anesthesia, then a continuous infusion of 2 mg.kg.h intraoperatively and 1.33 mg.kg.h for 24 h postoperatively) or an equal volume of saline. All patients received similar intensive postoperative rehabilitation. Postoperative pain scores, opioid consumption, and fatigue scores were measured. Times to first flatus, defecation, and hospital discharge were recorded. Postoperative endocrine (cortisol and catecholamines) and metabolic (leukocytes, C-reactive protein, and glucose) responses were measured for 48 h. Data (presented as median [25-75% interquartile range], lidocaine vs. saline groups) were analyzed using Mann-Whitney tests. P<0.05 was considered statistically significant. RESULTS: Patient demographics were similar in the two groups. Times to first flatus (17 [11-24] vs. 28 [25-33] h; P<0.001), defecation (28 [24-37] vs. 51 [41-70] h; P=0.001), and hospital discharge (2 [2-3] vs. 3 [3-4] days; P=0.001) were significantly shorter in patients who received lidocaine. Lidocaine significantly reduced opioid consumption (8 [5-18] vs. 22 [14-36] mg; P=0.005) and postoperative pain and fatigue scores. In contrast, endocrine and metabolic responses were similar in the two groups. CONCLUSIONS: Intravenous lidocaine improves postoperative analgesia, fatigue, and bowel function after laparoscopic colectomy. These benefits are associated with a significant reduction in hospital stay.     

Intravenous Lidocaine Infusion Facilitates Acute Rehabilitation after Laparoscopic Colectomy

Background: Intravenous infusion of lidocaine decreases postoperative pain and speeds the return of bowel function. The authors therefore tested the hypothesis that perioperative lidocaine infusion facilitates acute rehabilitation protocol in patients undergoing laparoscopic colectomy.

Methods: Forty patients scheduled to undergo laparoscopic colectomy were randomly allocated to receive intravenous lidocaine (bolus injection of 1.5 mg/kg lidocaine at induction of anesthesia, then a continuous infusion of 2 mg [middle dot] kg-1 [middle dot] h-1 intraoperatively and 1.33 mg [middle dot] kg-1 [middle dot] h-1 for 24 h postoperatively) or an equal volume of saline. All patients received similar intensive postoperative rehabilitation. Postoperative pain scores, opioid consumption, and fatigue scores were measured. Times to first flatus, defecation, and hospital discharge were recorded. Postoperative endocrine (cortisol and catecholamines) and metabolic (leukocytes, C-reactive protein, and glucose) responses were measured for 48 h. Data (presented as median [25-75% interquartile range], lidocaine vs. saline groups) were analyzed using Mann-Whitney tests. P < 0.05 was considered statistically significant.

Results: Patient demographics were similar in the two groups. Times to first flatus (17 [11-24] vs. 28 [25-33] h; P < 0.001), defecation (28 [24-37] vs. 51 [41-70] h; P = 0.001), and hospital discharge (2 [2-3] vs. 3 [3-4] days; P = 0.001) were significantly shorter in patients who received lidocaine. Lidocaine significantly reduced opioid consumption (8 [5-18] vs. 22 [14-36] mg; P = 0.005) and postoperative pain and fatigue scores. In contrast, endocrine and metabolic responses were similar in the two groups.     

Thoracic epidural analgesia facilitates the restoration of bowel function and dietary intake in patients undergoing laparoscopic colon resection using a traditional, nonaccelerated, perioperative care program

Background This randomized trial compared thoracic epidural analgesia with patient-controlled analgesia (PCA) using morphine for laparoscopic colectomy in a traditional, nonaccelerated, perioperative care program. Methods In the study, 50 patients scheduled for elective laparoscopic colon resection were randomized to either PCA morphine (n = 25) or thoracic epidural analgesia with bupivacaine and fentanyl (n = 25). Both groups received general anesthesia and multimodal pain relief, which included naproxen and acetaminophen for as long as 4 postoperative days. Time until passage of gas and bowel movements, dietary intake, postoperative quality of analgesia, readiness for discharge, and length of hospital stay were recorded. Results Recovery of postoperative ileus occurred sooner in the epidural group (p < 0.005) by an average 1 to 2 days, and resumption of full diet was achieved earlier (p < 0.05). Intensity of pain during the first 2 postoperative days was significantly lower at rest, with coughing, and with walking in the epidural group (p < 0.005). Readiness for discharge and hospital length of stay (5 days) were otherwise similar in the two groups. Conclusions When a traditional perioperative care program is used for laparoscopic colectomy, thoracic epidural analgesia is superior to PCA in accelerating the return of bowel function and dietary intake, while providing better pain relief.     

Use of Epidural Analgesia in Sigmoidectomy: Is There Any Advantage in the Era of Minimally Invasive Surgery?

Background

There is no consensus as to the effects of epidural analgesia on postoperative outcomes after laparoscopy in the context of the Enhanced Recovery Programs. The aim of this study was to evaluate the effects of epidural analgesia on postoperative outcomes after elective laparoscopic sigmoidectomy.

Methods

The use of epidural analgesia was discontinued in elective laparoscopic sigmoidectomy and substituted by the perioperative administration of systemic lidocaine. Data from patients undergoing elective laparoscopic sigmoidectomy between January 2014 and September 2016 was prospectively analysed. Patients with epidural analgesia were compared with patients without, in analgesics administrated postoperatively, length of stay, day of first defecation and mobilisation, and complication and reoperation rates.

Results

A total of 160 patients (male 85; female 75), median age 68 (30–92 years), were included. The groups consisted of 80 patients each. Mean length of stay (5.6 vs. 7.2 days, p?=?0.03) and day of first mobilisation (mean 1.2 vs. 1.6 days, p?=?0.004) were significantly shorter in the group without epidural analgesia. Reoperation rate (7.5 vs. 2.5%) was not statistically different. Complication rate was significantly lower (12.5 vs. 30%, p?=?0.007) in the group without epidural. Day of first defecation was shorter in the epidural group (1.4 vs. 1.7 days, p?=?0.04). Mean amount of analgesics administrated was not statistically different between groups, except for metamizole, that was administrated more in the group without epidural.

Conclusions

Epidural analgesia did not offer benefits on postoperative analgesia or outcomes after elective laparoscopic sigmoidectomy, causing longer length of stay, later mobilisation and higher complication rate.

     

Influence of thoracic epidural analgesia on postoperative pain relief and ileus after laparoscopic colorectal resection

Background  Thoracic epidural analgesia (TEA) provides superior analgesia with a lower incidence of postoperative ileus when compared with systemic opiate analgesia in open colorectal surgery. However, in laparoscopic colorectal surgery the role of TEA is not well defined. This prospective observational study investigates the influence of TEA in laparoscopic colorectal resections. Methods  All patients undergoing colorectal resection between November 2004 and February 2007 were assessed for inclusion into a prospective randomized trial investigating the influence of bisacodyl on postoperative ileus. All patients treated by laparoscopic resection from this collective were eligible for the present study. Primary endpoints were use of analgesics and visual analogue scale (VAS) pain scores. Secondary endpoint concerned full gastrointestinal recovery, defined as the mean time to the occurrence of the following three events (GI-3): first flatus passed, first defecation, and first solid food tolerated. Results  75 patients underwent laparoscopic colorectal resection, 39 in the TEA group and 36 in the non-TEA group. Patients with TEA required significantly less analgesics (metamizol median 3.0 g [0–32 g] versus 13.8 g [0–28 g] (p < 0.001); opioids mean 12 mg [±2.8 mg standard error of mean, SEM] versus 103 mg [±18.2 mg SEM] (p < 0.001). VAS scores were significantly lower in the TEA group (overall mean 1.67 [± 0.2 SEM] versus 2.58 [±0.2 SEM]; p = 0.004). Mean time to gastrointestinal recovery (GI-3) was significantly shorter (2.96 [±0.2 SEM] days versus 3.81 [±0.3 SEM] days; p = 0.025). Analysis of the subgroup of patients with laparoscopically completed resections showed corresponding results. Conclusion  TEA provides a significant benefit in terms of less analgesic consumption, better postoperative pain relief, and faster recovery of gastrointestinal function in patients undergoing laparoscopic colorectal resection.     

Laparoscopy for colectomy accelerates restoration of bowel function when using patient controlled analgesia

PURPOSE: A standardized care plan incorporating patient-controlled analgesia with iv morphine and a non-accelerated feeding schedule following colectomy was used to compare return of bowel function and hospital discharge times following surgery done by laparoscopy or laparotomy METHODS: Thirty-eight patients were assigned to undergo either laparoscopic or laparotomy colon resection. Postoperative analgesia was achieved with patient-controlled analgesia with iv morphine. General anesthesia and perioperative care were standardized, and a traditional surgical and nursing care program was implemented. Gastrointestinal function (time from surgery to return of passage of flatus and presence of bowel movements), pain intensity (visual analogue scale) at rest, on coughing and on mobilization, amount of morphine used, and criteria for discharge and length of hospital stay were recorded. RESULTS: Bowel movements resumed earlier in the laparoscopic group (P < 0.05), but not passage of flatus. No significant relationship was found between the amount of morphine used and return of bowel function. Cumulative morphine consumption during the first two postoperative days was similar in both groups. Where a trend towards lower postoperative visual analogue scale scores was observed in the laparoscopic group, visual analogue scale scores on coughing were lower in the laparoscopic vs laparotomy group only during the first 24 hr (P < 0.05). Length of hospital stay was significantly shorter in the laparoscopic group (P < 0.05), although times to meet discharge criteria were similar in both groups. CONCLUSIONS: When patient-controlled analgesia with morphine and a traditional perioperative program are used, a laparoscopic approach to colon surgery promotes earlier restoration of bowel function and more rapid hospital discharge in comparison to resection by laparotomy.     

Does mechanical massage of the abdominal wall after colectomy reduce postoperative pain and shorten the duration of ileus? Results of a randomized study

The aim of this study was to determine the effectiveness of mechanical abdominal massage on postoperative pain and ileus after colectomy. We hypothesized that parietal abdominal stimulation could counteract induced pain and postoperative ileus, through common spinal-sensitive pathways, with nociceptive visceral messages. After preoperative randomization, 25 patients (age 52 ± 5 years) underwent active mechanical massage by intermittent negative pressure on the abdominal wall resulting in aspiration (Cellu M50 device, LPG, Valence, France), and 25 patients (age 60 ± 6 years) did not receive active mechanical massage (placebo group). Massage sessions began the first day after colectomy and were performed daily until the seventh postoperative day. In the active-massage group, amplitude and frequency were used, which have been shown to be effective in reducing muscular pain, whereas in the placebo group, ineffective parameters were used. Visual analogue scale (VAS) pain scores, doses of analgesics (propacetamol), and delay between surgery and the time to first passage of flatus were assessed. Types and dosages of the anesthetic drugs and the duration of the surgical procedure did not differ between groups. From the second and third postoperative days, respectively, VAS pain scores (P < 0.001) and doses of analgesics (P < 0.05) were significantly lower in patients receiving active massage compared to the placebo group. Time to first passage of flatus was also significantly shorter in the active-massage group (1.8 ± 0.3 days vs. 3.6 ± 0.4 days, P < 0.01). No adverse effects were observed. These results suggest that mechanical massage of the abdominal wall may decrease postoperative pain and ileus after colectomy.

FastTrack approach to major colorectal surgery

Intensive rehabilitation programs after major abdominal, thoracic and vascular surgery have been published over the last few years, showing early recovery, fewer complications and a quicker discharge. The aim of the study was to evaluate the feasibility and efficacy of a multimodal intensive rehabilitation program (FastTrack) after major colorectal surgery, according to the experience of Dr. H. Kehlet of Hvidovre University Hospital, Copenhagen. The study design was of the prospective, randomized, controlled type. Forty patients undergoing elective colonic surgery were randomly selected and assigned to two groups well matched for age, weight, ASA and type of resection. The FastTrack group underwent a multimodal rehabilitation program with epidural analgesia, short laparotomy, early feeding and mobilisation. The control group had the usual postoperative treatment with a pain control program. The FastTrack group exhibited a shorter need for assisted ventilation, a lower sedation level and lower opioid consumption over the first 24 hours. We also observed a statistically significant earlier onset of peristalsis (0.5 vs 2.7 days), gastrointestinal function (defecation) (2.8 vs 5.8 days), regular feeding (3.1 vs 7.2 days) and autonomous ambulation (3.3 vs 6.9). The multimodal rehabilitation approach to colon surgery permits an earlier postoperative recovery, better postoperative performance and quicker functional autonomy. These results may have important implications for the management of patients after major colorectal surgery.     

Addition of transversus abdominis plane block to patient controlled analgesia for laparoscopic high anterior resection improves analgesia,reduces opioid requirement and expedites recovery of bowel function

IntroductionOpioid sparing in postoperative pain management appears key in colorectal enhanced recovery. Transversus abdominis plane (TAP) blocks offer such an effect. This study aimed to quantify this effect on pain, opioid use and recovery of bowel function after laparoscopic high anterior resection.MethodsThis was a retrospective analysis of prospective data on 68 patients. Patients received an epidural (n=24), intravenous morphine patient controlled analgesia (PCA, n=22) or TAP blocks plus PCA (n=22) determined by anaesthetist preference. Outcome measures were numerical pain scores (0–3), cumulative intravenous morphine dose and time to recovery of bowel function (passage of flatus or stool).ResultsThere were no differences in patient characteristics, complications or extraction site. The TAP block group had lower pain scores (0.7 vs 1.36, p<0.001) and morphine requirements (8mg vs 15mg, p=0.01) than the group receiving PCA alone at 12 hours and 24 hours. Earlier passage of flatus (2.0 vs 2.7 vs 3.4 days, p=0.002), stool (3.1 vs 4.1 vs 5.5 days, p=0.04) and earlier discharge (4 vs 5 vs 6 days, p=0.02) were also seen.ConclusionsUse of TAP blocks was found to reduce pain and morphine use compared with PCA, expedite recovery of bowel function compared with PCA and epidural, and expedite hospital discharge compared with epidural.     

Epidural analgesia with bupivacaine reduces postoperative paralytic ileus after hysterectomy

This study was undertaken to compare the effects of postoperative bupivacaine epidural analgesia with those of intermittent injections of ketobemidone (a synthetic opioid) on postoperative bowel motility in patients who had had hysterectomies. The epidural group (N = 20) received continuous epidural anesthesia with bupivacaine postoperatively for 26-30 hours and the control group (N = 20) received intermittent injections of ketobemidone for postoperative pain relief. Postoperative bowel movements and propulsive colonic motility were estimated from the first passage of flatus and feces and by following radiopaque markers by serial abdominal radiographs. In the epidural group, the times for first passing of flatus (31 +/- 22 hours; mean +/- SD) and feces (70 +/- 44 hours) were significantly shorter than in the control group (flatus 58 +/- 14 hours and feces 103 +/- 26 hours). The average position of the markers was significantly more distally in the epidural group immediately after operation and the markers continued to move forward during the first postoperative day. In the control group, the markers did not move during this period. The results demonstrate that postoperative bowel peristalsis returned earlier in the patients given epidural analgesia with bupivacaine for pain relief than in patients given a narcotic.     

Lidocaine vs. magnesium: effect on analgesia after a laparoscopic cholecystectomy

Background: This double‐blinded study aimed at evaluating and comparing the effects of magnesium and lidocaine on pain, analgesic requirements, bowel function, and quality of sleep in patients undergoing a laparoscopic cholecystectomy (LC). Methods: Patients were randomized into three groups (n=40 each). Group M received magnesium sulfate 50 mg/kg intravenously (i.v.), followed by 25 mg/kg/h i.v., group L received lidocaine 2 mg/kg i.v., followed by 2 mg/kg/h i.v., and group P received saline i.v. Bolus doses were given over 15 min before induction of anesthesia, followed by an i.v. infusion through the end of surgery. Intraoperative fentanyl consumption and averaged end‐tidal sevoflurane concentration were recorded. Abdominal and shoulder pain were evaluated up to 24 h using a visual analog scale (VAS). Morphine consumption was recorded at 2 and 24 h, together with quality of sleep and time of first flatus. Results: Lidocaine or magnesium reduced anesthetic requirements (P<0.01), pain scores (P<0.05), and morphine consumption (P<0.001) relative to the control group. Lidocaine resulted in lower morphine consumption at 2 h [4.9 ± 2.3 vs. 6.8 ± 2.8 (P<0.05)] and lower abdominal VAS scores compared with magnesium (1.8 ± 0.8 vs. 3.2 ± 0.9, 2.2 ± 1 vs. 3.6 ± 1.6, and 2.1 ± 1.4 vs. 3.3 ± 1.9) at 2, 6, and 12 h, respectively (P<0.05). Lidocaine was associated with earlier return of bowel function and magnesium was associated with better sleep quality (P<0.05). Conclusion: I.v. lidocaine and magnesium improved post‐operative analgesia and reduced intraoperative and post‐operative opioid requirements in patients undergoing LC. The improvement of quality of recovery might facilitate rapid hospital discharge.     

The effects of intravenous lidocaine on wound pain and gastrointestinal function recovery after laparoscopic colorectal surgery

To evaluate the efficacy of intravenous lidocaine in relieving postoperative pain and promoting rehabilitation in laparoscopic colorectal surgery, we conducted this meta‐analysis. The systematic search strategy was performed on PubMed, EMBASE, Chinese databases, and Cochrane Library before September 2019. As a result, 10 randomised clinical trials were included in this meta‐analysis (n = 527 patients). Intravenous lidocaine significantly reduced pain scores at 2, 4, 12, 24, and 48 hours on movement and 2, 4, and 12 hours on resting‐state and reduced opioid requirement in first 24 hours postoperatively (weighted mean difference [WMD] = −5.02 [−9.34, −0.70]; P = .02). It also decreased the first flatus time (WMD: −10.15 [−11.20, −9.10]; P < .00001), first defecation time (WMD: −10.27 [−17.62, −2.92]; P = .006), length of hospital stay (WMD: −1.05 [−1.89, −0.21]; P = .01), and reduced the incidence of postoperative nausea and vomiting (risk ratio: 0.53 [0.30, 0.93]; P = .03) when compared with control group. However, it had no effect on pain scores at 24 and 48 hours at rest, the normal dietary time, and the level of serum C‐reactive protein. In summary, perioperative intravenous lidocaine could alleviate acute pain, reduce postoperative analgesic requirements, and accelerate recovery of gastrointestinal function in patients undergoing laparoscopic colorectal surgery.     

A comparative study of the efficacy of postoperative analgesia with intraoperative epidural lidocaine with or without morphine

We compared postoperative analgesia in 15 patients (group A) who were given intraoperative epidural morphine 3 mg and lidocaine 150 mg after laminectomy/discectomy with that of 15 patients (group B) who were given only epidural lidocaine 150 mg. Epidural administration was accomplished by direct placement of the epidural catheter into the epidural space under direct vision during surgery. Eight patients (53%) in group A and 15 patients (100%) in group B required supplementary narcotics during the first 24 h postoperatively (P<0.05). The amount of supplementary narcotics given to group A patients was significantly less than that for group B (P<0.05), and the pain scores for group A patients were also significantly lower at 1, 2, and 6 h postoperatively (P<0.05). There was no difference in the observed side effects in the two groups. We conclude that postoperative pain relief following laminectomy/discectomy is superior when epidural morphine is added to lidocaine than when lidocaine is being used alone.

Gum chewing enhances early recovery from postoperative ileus after laparoscopic colectomy

BACKGROUND: Postoperative ileus limits early hospital discharge for patients who have undergone laparoscopic procedures. Sham feeding has been reported to enhance bowel motility. Here, the effect of gum chewing is evaluated as a convenient method to enhance postoperative recovery from ileus after laparoscopic colectomy. STUDY DESIGN: A total of 19 patients who underwent elective laparoscopic colectomy for colorectal cancer participated in the study. Each patient was randomly assigned to one of two groups: a gum-chewing group (n = 10, mean age 58.6 years, range 50 to 71 years) or a control group (n = 9, mean age 60.6 years, range 45 to 80 years). The patients in the gum-chewing group chewed gum three times a day from the first postoperative AM until oral intake. The times of the first passage of flatus and defecation were recorded precisely. RESULTS: The first passage of flatus was seen, on average, on postoperative day 2.1 in the gum-chewing group and on day 3.2 in the control group (p < 0.01). The first defecation was 2.7 days sooner in the gum-chewing group (postoperative day 3.1) than in the control group (5.8 days; p< 0.01). All patients tolerated gum chewing on the first operative AM. The postoperative hospital stays for the gum-chewing and control groups were 13.5+/-3.0 days and 14.5+/-6.1 days, respectively. CONCLUSIONS: Gum chewing aids early recovery from postoperative ileus and is an inexpensive and physiologic method for stimulating bowel motility. Gum chewing should be added as an adjunct treatment in postoperative care because it might contribute to shorter hospital stays.     

Comparación del bloqueo del grupo de nervios pericapsulares (PENG) y la analgesia epidural después de una artroplastia total de cadera: análisis retrospectivo

Introduction and objectivesTotal hip arthroplasty (THA) is an increasingly common orthopedic pro-cedure, with moderate to severe postoperative pain. Pericapsular nerve group (PENG) block is a recent block that seems to provide adequate analgesia without significant motor blockade. The aim of this study is to retrospectively compare the analgesic efficacy and safety of PENG block with those of epidural analgesia, in patients undergoing THA.Material and methodsThis is a retrospective observational study of patients who underwent primary THA, submitted to epidural analgesia or single-shot ultrasound-guided PENG block, during a one-year period. Data regarding demographic characteristics, surgery and anesthesia techniques, pain scores, opioid consumption, complications and time to hospital discharge were retrieved from institutional records and compared between the 2 groups (epidural analgesia vs PENG block).ResultsNo significant difference was found regarding pain scores, opioid consumption, and mean time to hospital discharge between the 2 groups. Pain scores at rest (1.20 epidural vs 1.67 PENG) or with movement (3.95 epidural vs 3.72 PENG) were similar between groups. Total number of complications was higher in the epidural analgesia group (50% epidural vs 5% PENG). Paresthesia was reported in both groups. Motor block, sedation, nausea and catheter-related complications were only found in the epidural analgesia group.ConclusionsPENG block seems to be equivalent to epidural analgesia regarding quality of postop-erative analgesia for patients subject to primary THA, supporting routine use of this block in these patients. The low rate of reported complications limits conclusions on this topic.     

Further reduction of hospital stay for laparoscopic colon resection by modifications of the fast-track care plan

Background

Fast-track surgery has been described as a plan to facilitate early recovery. We present one surgeon's modifications to fast-track surgery for laparoscopic colectomy patients.

Methods

We performed a retrospective review of 48 consecutive patients undergoing elective laparoscopic colectomy treated by a modified fast-track plan between 2004 and 2008. Elements included preoperative education, pre-anesthesia dexamethasone, immediate postoperative general diet, no urinary catheter, no epidural anesthesia, and no flatus or bowel movement as a discharge requirement. Data collected included the following: age, sex, body mass index, resection indications, surgical time, blood loss, pain score, time to ambulation, time to bowel function, length of stay, complications, and mortality.

Results

The mean length of stay was 37 hours (1.5 d), with 29 of 48 patients discharged without passage of flatus or stool. Only 1 patient required readmission.

Conclusions

Our modified fast-track plan achieved significant improvement in length of stay for laparoscopic colectomy compared with previous results.     

Preincisional dextromethorphan combined with thoracic epidural anesthesia and analgesia improves postoperative pain and bowel function in patients undergoing colonic surgery

Colonic surgery is associated with severe postoperative pain and postoperative ileus, which contribute to delayed hospital discharge. In previous studies, we demonstrated that IM dextromethorphan (DM) provided preemptive analgesia and improved postoperative pain. The benefit of thoracic epidural anesthesia (TEA) and postoperative epidural analgesia on postoperative pain was well demonstrated. The goal of this study was to investigate the effect of preincisional IM DM combined with intraoperative TEA and postoperative patient-controlled epidural analgesia (PCEA) on pain and bowel function after colonic surgery. Patients were randomized into 3 equal groups to receive: 1) chlorpheniramine maleate (CPM) 20 mg and general anesthesia (CPM-GA); 2) CPM 20 mg and GA combined with TEA (CPM-TEA); or 3) DM 40 mg (containing 20 mg of CPM) and GA combined with TEA (DM-TEA). The CPM, DM, and TEA with lidocaine were administered after GA induction via an IM injection and 30 min before the skin incision. All patients received postoperative PCEA for pain control. Analgesic effects were evaluated for 72 h after surgery using visual analog scale pain scores at rest and moving, time to first PCEA request for pain relief, total PCEA consumption, and the time to first passage of flatus. Statistically significant improvement of postoperative pain and bowel function was observed in the following order: DM-TEA > CPM-TEA > CPM-GA. Compared with the CPM-TEA group, the DM-TEA group averaged 1.6 points lower on first-hour pain scores, 40 min longer to first PCEA request, 15.8 mL less PCEA drug over 72 h, and 14.7 h earlier bowel function (all P < 0.01). We conclude that the combination of preincisional DM (40 mg IM), intraoperative TEA, and postoperative PCEA enhances analgesia and facilitates recovery of bowel function, suggesting possible synergistic interaction with local anesthetics and opioids.     

Preoperative adjuvant epidural tramadol: the effect of different doses on postoperative analgesia and pain processing

Background: Tramadol is an analgesic with combined opioid agonist and monoamine reuptake blocker properties, which may be useful as a perioperative analgesic and antinociceptive adjuvant.
Methods: The dose-dependent effects of adjuvant preoperative epidural tramadol on postoperative analgesia (pain scores and patient-controlled analgesia (PCA) use) and pain processing (heat pain thresholds) were prospectively studied in a double-blind, randomised, placebo-controlled 5-day trial. Forty patients undergoing knee or hip surgery received anaesthesia with epidural lidocaine and epidural tramadol 20, 50 or 100 mg or placebo as a preoperative adjuvant. Postoperative analgesia was by intravenous PCA tramadol in all patients.
Results: Postoperative pain scores were similar in all groups. The time to first PCA use was shorter, the total dose and duration of PCA use greater, and side-effects more common with 20 mg tramadol than with 100 mg or placebo ( P <0.05). There were no differences in PCA doses required or side-effects between the tramadol 100 mg and placebo treatment groups. Heat pain tolerance thresholds were increased with 100 mg tramadol at 48 h postoperatively compared to baseline and placebo ( P = 0.01).
Conclusions: Preoperative adjuvant epidural tramadol does not improve postoperative analgesia after lidocaine epidural anaesthesia compared to placebo. Tramadol 20 mg results in anti-analgesia and increased side-effects. While tramadol 100 mg depresses postoperative pain-processing, as measured by heat pain tolerance thresholds, this is not reflected in improved clinical pain measures.     

Posterior quadratus lumborum block versus epidural analgesia for postoperative pain management after open radical cystectomy: A randomized clinical trial

Background

In open abdominal surgery, continuous epidural analgesia is commonly used method for postoperative analgesia. However, ultrasound (US)-guided fascial plane blocks may be a reasonable alternative.

Methods

In this randomized controlled trial, we compared posterior quadratus lumborum block (QLB) with epidural analgesia for postoperative pain after open radical cystectomy (ORC). Adult patients aged 18–85 with bladder cancer (BC) scheduled for open RC were randomized in two groups. Exclusion criteria were complicated diabetes mellitus type I, lack of cooperation, and persistent pain for reasons other than BC. In one group, a bilateral US-guided single injection posterior QLB was performed with 3.75 mg/ml ropivacaine 20 ml/side. In the other group, continuous epidural analgesia with ropivacaine was used. Basic analgesia was oral paracetamol 1000 mg three times daily, and long-acting opioid twice daily in both groups. All patients had patient-controlled rescue analgesia with oxycodone. Postoperative cumulative rescue opioid consumption was recorded for the day of surgery, and the following 2 postoperative days (POD 0–2). Secondary outcomes were postoperative pain and nausea and vomiting.

Results

In total, 20 patients (QLB), and 19 patients (epidural analgesia) groups, were included in the analyses. Cumulative rescue opioid consumption on POD 0, being of duration 9–12 h, was 14 mg (7.6–33.3) in the QLB group versus 6.1 mg (2.0–16.1) in the epidural analgesia group, p = 0.089, and as doses, 8 doses (3.6–15.7) versus 4 doses (1.3–8.5), p = .057. On POD 1 consumption was 25.3 mg (11.0–52.9) versus 18.0 mg (14.4–43.7), p = .749, and as doses 12 (5.5–23.0) versus 10 (8–20), p > .9, respectively. On POD 2 consumption was 19.1 mg (7.9–31.0) versus 18.0 mg (5.4–27.6) p = .749, and as doses 8.5 (5.2–14.7) versus 11 (3.0–18.0) p > .9, respectively.

Conclusion

Opioid consumption did not differ significantly between posterior QLB and an epidural infusion with ropivacaine for the first 2 postoperative days following RC. Trial registration: ClinicalTrials.gov identifier NCT03328988.
