Efficacy of profound versus moderate neuromuscular blockade in enhancing postoperative recovery after laparoscopic donor nephrectomy: A randomised controlled trial.

ABSTRACT: BACKGROUND:Profound neuromuscular blockade (NMB) during anaesthesia has been shown to reduce postoperative pain scores, when compared with a moderate block. We hypothesised that profound NMB during laparoscopic donor nephrectomy (LDN) could also improve the early quality of recovery after surgery. OBJECTIVES:To compare the effectiveness of profound versus moderate NMB during LDN in enhancing postoperative recovery. DESIGN:A phase IV, double-blinded, randomised controlled trial. SETTING:Multicentre trial, from November 2016 to December 2017. PATIENTS:A total of 101 living kidney donors scheduled for LDN were enrolled, and 96 patients were included in the analyses. INTERVENTIONS:Patients were randomised to receive profound (posttetanic count 1 to 3) or moderate (train-of-four count 1 to 3) neuromuscular block. MAIN OUTCOME MEASURES:The primary outcome was the early quality of recovery at postoperative day 1, measured by the Quality of Recovery-40 Questionnaire. Secondary outcomes were adverse events, postoperative pain, analgesic consumption and length-of-stay. RESULTS:The intention-to-treat analysis did not show a difference with regard to the quality of recovery, pain scores, analgesic consumption and length-of-stay. Less intra-operative adverse events occurred in patients allocated to profound NMB (1/48 versus 6/48). Five patients allocated to a profound NMB received a moderate block and in two patients neuromuscular monitoring failed. The as-treated analysis revealed that pain scores were significantly lower at 6, 24 and 48?h after surgery. Moreover, the quality of recovery was significantly better at postoperative day 2 in patients receiving a profound versus moderate block (179.5?±?13.6 versus 172.3?±?19.2). CONCLUSION:Secondary analysis indicates that an adequately maintained profound neuromuscular block improves postoperative pain scores and quality of recovery. As the intention-to-treat analysis did not reveal a difference regarding the primary endpoint, future studies should pursue whether a thoroughly maintained profound NMB during laparoscopy improves relevant patient outcomes.

Project description:BackgroundAnesthesia with deep neuromuscular block for laparoscopic surgery may result in less postoperative pain with lower intra-abdominal pressure. However, the results in the existing literature are controversial. This study aimed to evaluate the effect of deep versus moderate neuromuscular block (NMB) on the postoperative recovery characteristics after laparoscopic sleeve gastrectomy (LSG) for weight loss surgery.MethodsThis is parallel-group, randomized clinical trial. The study was conducted at a tertiary care center. Patients undergoing LSG were included. Patients were randomly assigned to either deep (post-tetanic count 1-2) or moderate (train-of-four 1-2) NMB group. The primary outcomes were numeric rating scale scores of the postoperative pain at rest and postoperative shoulder pain. The secondary outcomes were the length of hospital stay (LOS) and postoperative complications. The statistics were performed using StatsDirect statistical software (Version 2.7.9).ResultsTwo groups were identified: Group D (deep NMB), 29 patients, and Group M (moderate NMB), 28 patients. The BMI mean values for groups D and M were 44 and 45 kg/m2 respectively (P > 0.05). The mean durations of surgery for were 46.7 min and 44.1 min for groups M and D, respectively (P > 0.05). The mean train-of-four (TOF) counts were 0.3 and 0 for groups M and D, respectively (P < 0.05). The mean times from giving reversal agent to tracheal extubation (minutes) were 6.5 and 6.58 min for groups M and D, respectively (P > 0.05). In the recovery room, the means of pain scores were 3 and 4 for groups M and D, respectively (P > 0.05). Upon admission to the surgical ward, the median values of the pain score were non-significant (P > 0.05) (95% CI: 0.4-0.7). The opioid consumption in the recovery room was non-significant between both groups (P > 0.05) (95% CI: 0.3-0.6). Postoperative shoulder pain was non-significant between both groups (P > 0.05) (95% CI: 0.4-0.7). The median values of surgeon opinion of both groups were non-significant (P > 0.05). Regarding the LOS, the mean values of groups D and M were 1.20 and 1.21 days, respectively (P > 0.05).ConclusionsThere was no significant difference between moderate and deep NMB techniques in terms of duration of the surgical procedure, postoperative pain, shoulder pain, and length of hospital stay. Further studies on a larger sample size are required to investigate the long-term recovery characteristics of patients with obesity undergoing LSG.
