Quadratus Lumborum

BackgroundRobotic and hand-assisted laparoscopic nephrectomies are often associated with moderate to severe postoperative pain. The aim of the current study was to investigate the analgesic efficacy of the transmuscular quadratus lumborum (TQL) block for patients undergoing robotic or hand-assisted laparoscopic nephrectomy.MethodsFifty patients were included in this single-center study. All patients were scheduled for elective hand-assisted or robotic laparoscopic nephrectomy under general anesthesia. Preoperatively, patients were randomly allocated to TQL block bilaterally with ropivacaine 60 mL 0.375% or 60 mL saline and all patients received standard multimodal analgesia and intravenous patient-controlled analgesia. Primary outcome was postoperative oral morphine equivalent (OME) consumption 0–12 hours. Secondary outcomes were postoperative OME consumption up to 24 hours, pain scores, time to first opioid, nausea/vomiting, time to first ambulation and hospital length of stay (LOS).ResultsMean (95% CI) OME consumption was significantly lower in the intervention group at 12 hours after surgery 50 (28.5 to 71.5) mg versus control 87.5 (62.7 to 112.3) mg, p=0.02. At 24 hours, 69.4 (43.2 to 95.5) mg versus 127 (96.7 to 158.6) mg, p<0.01. Time to first opioid was significantly prolonged in the intervention group median (IQR) 4.4 (2.8–17.6) hours compared with 0.3 (0.1–1.0) hours in the control group, p<0.001. No significant intergroup differences were recorded for time to first ambulation, pain scores, nausea/vomiting nor for LOS.ConclusionPreoperative bilateral TQL block significantly reduced postoperative opioid consumption by 43% and significantly prolonged time to first opioid.Trial registration numberNCT03571490.

Abstract Abstract: With the implementation of enhanced recovery pathways (ERAS) in kidney surgeries, regional techniques are being considered an important aspect of multimodal analgesia. Abdominal blocks such as quadratus lumborum block (QLB) have been used as an effective analgesic in abdominal surgeries, however their efficacy in kidney surgery remains unknown. To our best knowledge, there are no clinical studies exploring the relationship between QLBs and post-operative opioid consumption in robotic laparoscopic nephrectomy. Study Objectives: Assess analgesic efficacy between QLB and post-operative opioid consumption in robotic laparoscopic nephrectomy. Design and Setting: A retrospective chart review was conducted by querying the electronic medical record system of 2,200 bed tertiary academic hospital center in New York City. Outcomes: The primary measured outcome was postoperative morphine milli equivalent (MME) consumption for the first 24 hours. Secondary outcomes include intra-operative MME, as well as postoperative pain scores measured on a visual analogue scale (VAS) scale at 2, 6, 12, 18, and 24 hours post-operatively. Results: The mean total post-operative MME in the pQLB group was 11 [4, 18] and 15 [5.6, 28] in the control group (p =.001). There was a significant reduction in intra-operative MME in the QLB group in comparison to the control group. This reduction was not seen in post-operative MME. There was no significant difference in pain scores at any of the measured time points up to 24 hours post-operatively. Conclusion: Our study provides compelling support that ultrasound guided QLB significantly decreased intra operative opioid requirements but did not have the same effect on postoperative opioid requirements following robotic kidney surgeries in the context of an ERAS pathway.

BACKGROUND: Patients undergoing bariatric surgery present unique analgesic challenges, including poorly controlled pain, increased prevalence of obstructive sleep apnea, and opioid-induced respiratory depression. The transversus abdominis plane (TAP) has been demonstrated to be a safe and effective component of multimodal analgesia for a variety of abdominal surgeries. OBJECTIVE: To determine the benefits of the TAP block on postoperative analgesia and recovery in patients undergoing bariatric surgery. STUDY DESIGN: Systematic review and meta-analysis of randomized controlled trials (RCTs) and non-randomized studies. METHODS: We conducted a comprehensive search of MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) databases from inception to April 2020 for studies using TAP block in bariatric surgeries and reporting postoperative pain, opioid consumption, and recovery-related outcomes. Primary outcomes included postoperative pain scores, opioid consumption, and recovery-related outcomes (e.g., length of stay, time to ambulation). Outcomes were pooled using random effects model and reported as relative risks (RR) or mean differences (MD) with 95% confidence intervals (CI). RESULTS: Twenty-one studies (15 RCTs [n = 1410] and 6 nonrandomized studies [n = 1959]) were included. Among RCTs, the TAP block group required fewer opioid rescues (RR 0.28; 95% CI 0.18 to 0.42, P < 0.001) (moderate quality); reduced total opioid use over 24 hours (MD –8.33; 95% CI –14.78 to –1.89, P = 0.01); decreased time to ambulation (MD –1.12 hours; 95% CI –1.50 to –0.73, P < 0.001) (high quality); and had significantly lower pain scores at 6 hours (MD –1.52; 95% CI –1.90 to –1.13, P < 0.01) and 12 hours (MD –0.95; 95% CI –1.34 to –0.56, P < 0.001) on a 0-10 pain scale (moderate quality). No difference was observed for nausea and vomiting, or hospital length of stay. Meta-analyzed outcomes from observational studies supported these results, suggesting decreased postoperative pain and opioid consumption. LIMITATIONS: Studies varied with respect to type of surgery and components of comparator multimodal analgesia, likely contributing to heterogeneity. Subgroup analyses by type of comparator group were conducted to address these differences. We were unable to extract data from all trials included due to variability in outcomes reporting, such as non-opioid drugs for postoperative pain management or invalid dosages. Pain-related outcomes may be affected by operative differences leading to variation in visceral pain. Observational studies have their inherent limitations, such as confounding due to lack of participant randomization and intervention blinding, potentially affecting subjective outcomes, such as pain scores, as well as provider-dependent outcomes, such as hospital length of stay. Lastly, there was significant variation of TAP block technique across all studies. CONCLUSION: TAP block is an effective, safe modality that can be performed under anesthesia. It decreases pain, opioid use, and time to ambulation after bariatric surgeries and should be considered in multimodal analgesia for enhanced recovery in this high-risk surgical population.

Introduction. Obesity is a common comorbidity seen in the perioperative setting and is associated with many diseases including cardiovascular disease and obstructive sleep apnea. Laparoscopic Roux-en-Y gastric bypass is the gold standard surgical treatment for patients whose weight is refractory to diet and exercise. Caring for these patients perioperatively presents unique challenges to anesthesiologists and is associated with an increased risk of adverse respiratory events. In our study, we hypothesize that a low-dose perioperative ketamine infusion will reduce opioid consumption and improve analgesia when compared to standard therapy. Methods. This is a single-center, prospective randomized controlled study enrolling 35 patients in total. Patients were randomized equally into the ketamine and control group. Preop, intraop, and postop management regimens were standardized. The ketamine group received a 0.3 mg/kg ideal body weight ketamine bolus after induction followed by a 0.2 mg/kg/hr ketamine infusion continued into the postop setting for up to 24 hours. Data collected included total perioperative opioids used converted to oral morphine equivalents (ME), pain scores, side effects, hospital length of stay, and patient satisfaction captured via postoperative questionnaires. Results. The use of perioperative opioid consumption was significantly lower in the ketamine group when compared with the control group (179.9 ME versus 248.7 ME, P = 0.03 ). There was no statistically significant difference in pain scores or hospital length of stay postoperatively between the two groups. There were also no reported adverse respiratory events, prolonged sedation, agitation, or other side effects reported in either group. The patient satisfaction questionnaires showed a significant difference with the ketamine group reporting lower maximum pain scores, a decrease in how pain limited activities of daily living once discharged, and increased hospital pain management satisfaction scores. Conclusions. Perioperative low-dose ketamine infusions significantly reduced opioid consumption in morbidly obese patients undergoing laparoscopic gastric bypass surgery.

Abstract Background: Epidural (EPI) catheter analgesia is frequently prescribed as a regional analgesic technique to patients with multiple rib fractures (MRF) following surgical stabilization of rib fractures (SSRF). We aimed to study the effect of add-on self-care therapy on recovery and quality of life (QoL) in patients on EPI analgesia after SSRF. Methods: A total of 267 patients with MRF and on EPI catheter analgesia post SSRF were recruited, and assigned to one of two groups in a random fashion: intervention group received education on self-care therapy, while the control group did not. Incentive spirometry (IS) volumes, Pain scores, oxygen saturation (SpO2), respiratory rate, hospital length of stay (LoS) and QoL were evaluated. Results: Compared to control group, the intervention group showed significantly improved pain scores, IS volume, respiratory rate and SpO2. Hospital LoS was shorter for the intervention group than control. Overall QoL assessments in the intervention group were also significantly better than control patients. Conclusion: Education on self-care therapy significantly benefits pain management, recovery and QoL for MRF patients on EPI catheter analgesia after SSRF operation.

Abstract Background Recently, several case reports and limited randomized studies have shown that quadratus lumborum blocks (QLB) are effective in providing pain relief after intra-abdominal and retroperitoneal operations. Additionally, robot-assisted partial nephrectomy (RAPN) has been proposed as a promising operative treatment for renal carcinoma because it enables early recovery and ambulation. Therefore, we aimed to evaluate the analgesic and opioid-sparing effects of a single-injection QLB in patients undergoing RAPN to determine its role in an early recovery program. Methods Fifty-six patients undergoing elective RAPN under general anesthesia were randomized to two equally sized groups. Patients were randomly allocated to receive either a unilateral QLB (n = 28) with 0.375% bupivacaine 0.5 mL/kg (QLB group) or a conventional scheme (n = 28) (control group). The QLB technique, termed QLB2, was performed as first described by Blanco. The primary outcome was visual analog scale (VAS) scores with movement at 6 h postoperatively. The secondary endpoints were morphine consumption at different time periods after surgery, morphine-related side effects, and assessment of postoperative rehabilitation. Results Both the VAS pain scores and cumulative opioid consumption were significantly lower in the QLB group at 6 h after surgery as compared with results in the control group (all P < 0.05). There were significant differences in pain scores at all time points except at 4 h with movement and 48 h at rest. However, at 12–24 h no significant differences between the two groups were observed in cumulative opioid consumption or in the duration of PACU and hospital stays. The patient recovery scores were significantly higher in the QLB group. Conclusions Single-injection pre-emptive QLB applied to RAPN was effective and provided satisfactory analgesia and opioid-sparing effects in combination with typical patient-controlled analgesia. In addition, it may provide an effective technique for early recovery in the perioperative period for RAPN.

Background: The management of post-operative pain and high levels of acute and chronic opioid use following total knee arthroplasty (TKA) and total hip arthroplasty (THA) remain challenges to the perioperative team. We performed a systematic review and meta-analysis to determine the opioid sparing effects, analgesic effects, and safety profile of perioperative gabapentinoid usage in lower limb arthroplasty.Methods: We searched multiple databases from inception until May 2019 and included randomized controlled trials (RCT) on perioperative gabapentinoids in lower limb arthroplasty. The primary outcome was cumulative opioid consumption (oral morphine equivalents) at 24 and 48 hours, and the secondary outcomes were pain scores, time to hospital discharge, and adverse events including nausea, vomiting, pruritus, and sedation. Methodological quality was assessed using the Cochrane tool. The grading of recommendations assessment, development, and evaluation methodology for the certainty of evidence was also used.Results: We included 19 RCT involving 2,455 patients undergoing lower limb arthroplasty. The overall methodological quality of included studies was good. Gabapentinoid use was associated with a significant reduction in opioid consumption at 24 hour (mean difference (MD) 22.81 mg [95 percent Confidence Interval (CI) 13.64-31.98]) and 48 hour (MD 44.03 mg [95 percent CI 16.92-71.14]). We found no meaningful difference in pain scores at rest between gabapentinoid and placebo groups at 24 or 48 hours. Gabapentinoid use reduced the risk of postoperative nausea (risk ratio (RR) 0.69 [95 percent CI 0.57-0.82]), vomiting (RR 0.65 [95 percent CI 0.47-0.91]), and pruritus (RR 0.60 [0.37-0.98]), but not sedation (RR 1.25 [0.76-2.06]). There was no effect on time to discharge from hospital (MD—0.05 days [95 percent CI −0.31 to 0.20].Conclusions: The addition of gabapentinoids to perioperative multimodal analgesia decreases opioid consumption following lower limb arthroplasty, while also lowering rates of nausea, vomiting, and pruritus. Further study is required to evaluate the effect of gabapentinoid use on long-term opioid use and dependence.

Quadratus Lumborum

Background Pain management is important for ensuring early mobilization after hip arthroplasty; however, the optimal components remain controversial. Recently, the quadratus lumborum block has been proposed as an analgesic option. The current study tested the hypothesis that the posterior quadratus lumborum block combined with multimodal analgesia decreases morphine consumption after hip arthroplasty. Methods This study was a prospective, randomized, double-blind, placebo-controlled trial. Before general anesthesia, 100 participating patients scheduled for elective total hip arthroplasty were randomly allocated to receive a 30-ml injection posterior to the quadratus lumborum muscle with either 0.33% ropivacaine (n = 50) or normal saline (n = 50). For all patients, multimodal analgesia included systematic administration of acetaminophen, ketoprofen, and a morphine intravenous patient-controlled analgesia. The primary outcome was total intravenous morphine consumption in the first 24 h. Secondary outcomes recorded intraoperative sufentanil consumption; morphine consumption in the postanesthesia care unit; pain scores at extubation and at 2, 6, 12, and 24 h; motor blockade; time to first standing and ambulation; hospital length of stay; and adverse events. Results There was no significant difference in the 24-h total morphine consumption (ropivacaine group, median [interquartile range], 13 [7 to 21] versus saline group, 16 [9 to 21] mg; median difference, −1.5; 95% CI, −5 to 2; P = 0.337). Pain scores were not different between the groups (β = −0.4; 95% CI, −0.9 to 0.2; P = 0.199). There was no statistical difference between the two groups in intraoperative sufentanil consumption, morphine consumption in the postanesthesia care unit, motor blockade, times to first standing (median difference, 0.83 h; 95% CI, −1.7 to 3.4; P = 0.690) and ambulation (median difference, −1.85 h; 95% CI, −4.5 to 0.8; P = 0.173), hospital length of stay, and adverse events. Conclusions After elective hip arthroplasty, neither morphine consumption nor pain scores were reduced by the addition of a posterior quadratus lumborum block to a multimodal analgesia regimen.

Background and objectivesAt our institution, we developed an individualized discharge opioid prescribing and tapering protocol for joint replacement patients and implemented the same protocol for neurosurgical spine patients. We then tested the hypothesis that this protocol will decrease the oral morphine milligram equivalent (MME) dose of opioid prescribed postdischarge after elective primary spine surgery.MethodsIn this retrospective cohort study, we identified all consecutive elective primary spine surgery cases 1 year before and after introduction of the protocol. This protocol used the patient’s prior 24-hour inpatient opioid consumption to determine discharge opioid pill count and tapering schedule. The primary outcome was total opioid dose prescribed in oral MME from discharge through 6 weeks. Secondary outcomes included in-hospital opioid consumption in MME, hospital length of stay, MME prescribed at discharge, opioid refills, and rates of minor and major adverse events.ResultsEighty-three cases comprised the final sample (45 preintervention and 38 postintervention). There were no differences in baseline characteristics. The total oral MME (median (IQR)) from discharge through 6 weeks postoperatively was 900 (420–1440) preintervention compared with 300 (112–806) postintervention (p<0.01, Mann-Whitney U test), and opioid refill rates were not different between groups. There were no differences in other outcomes.ConclusionsThis patient-specific prescribing and tapering protocol effectively decreases the total opioid dose prescribed for 6 weeks postdischarge after elective primary spine surgery. Our experience also demonstrates the potential generalizability of this protocol, which was originally designed for joint replacement patients, to other surgical populations.

Background: Patients undergoing periacetabular osteotomy (PAO) may experience significant postoperative pain due to the extensive approach and multiple osteotomies. The aim of this study was to assess the efficacy of the transversus abdominis plane (TAP) block on reducing opioid consumption and improving clinical outcome in PAO patients. Patients and Methods: We conducted a two-group randomized-controlled trial in 42 consecutive patients undergoing a PAO for symptomatic developmental dysplasia of the hip (DDH). The study group received an ultrasound-guided TAP block with 20 mL of 0.75% ropivacaine prior to surgery. The control group did not receive a TAP block. All patients received a multimodal analgesia with nonsteroidal anti-inflammatory drugs (NSAID) (etoricoxib and metamizole) and an intravenous patient-controlled analgesia (PCA) with piritramide (1.5 mg bolus, 10 min lockout-time). The primary endpoint was opioid consumption within 48 h after surgery. Secondary endpoints were pain scores, assessment of postoperative nausea and vomiting (PONV), measurement of the quality of recovery using patient-reported outcome measure and length of hospital stay. Forty-one patients (n = 21 TAP block group, n = 20 control group) completed the study, per protocol. One patient was lost to follow-up. Thirty-three were women (88.5%) and eight men (19.5%). The mean age at the time of surgery was 28 years (18–43, SD ± 7.4). All TAP blocks were performed by an experienced senior anaesthesiologist and all operations were performed by a single, high volume surgeon. Results: The opioid consumption in the TAP block group was significantly lower compared to the control group at 6 (3 mg ± 2.8 vs. 10.8 mg ± 5.6, p < 0.0001), 24 (18.4 ± 16.2 vs. 30.8 ± 16.4, p = 0.01) and 48 h (29.1 mg ± 30.7 vs. 54.7 ± 29.6, p = 0.04) after surgery. Pain scores were significantly reduced in the TAP block group at 24 h after surgery. There were no other differences in secondary outcome parameters. No perioperative complication occurred in either group. Conclusion: Ultrasound-guided TAP block significantly reduces the perioperative opioid consumption in patients undergoing PAO.

Abstract Background Postoperative pain and opioid use are associated with postoperative delirium. We designed a single-center, randomized, placebo-controlled, parallel-arm, double-blinded trial to determine whether perioperative administration of gabapentin reduced postoperative delirium after noncardiac surgery. Methods Patients were randomly assigned to receive placebo (N = 347) or gabapentin 900 mg (N = 350) administered preoperatively and for the first 3 postoperative days. The primary outcome was postoperative delirium as measured by the Confusion Assessment Method. Secondary outcomes were postoperative pain, opioid use, and length of hospital stay. Results Data for 697 patients were included, with a mean ± SD age of 72 ± 6 yr. The overall incidence of postoperative delirium in any of the first 3 days was 22.4% (24.0% in the gabapentin and 20.8% in the placebo groups; the difference was 3.20%; 95% CI, 3.22% to 9.72%; P = 0.30). The incidence of delirium did not differ between the two groups when stratified by surgery type, anesthesia type, or preoperative risk status. Gabapentin was shown to be opioid sparing, with lower doses for the intervention group versus the control group. For example, the morphine equivalents for the gabapentin-treated group, median 6.7 mg (25th, 75th quartiles: 1.3, 20.0 mg), versus control group, median 6.7 mg (25th, 75th quartiles: 2.7, 24.8 mg), differed on the first postoperative day (P = 0.04). Conclusions Although postoperative opioid use was reduced, perioperative administration of gabapentin did not result in a reduction of postoperative delirium or hospital length of stay.
