Abstract
INTRODUCTION
Many clinical trials have demonstrated the benefits of intraoperative systemic lidocaine administration in major abdominal surgeries. We tested the hypothesis that systemic lidocaine is associated with an enhanced early quality of recovery in patients following laparoscopic colorectal resection.
PATIENTS AND METHODS
We randomly allocated 126 patients scheduled for laparoscopic colorectal surgery in a 1:1 ratio to receive either lidocaine (1.5 mg kg-1 bolus over 10 min, followed by continuous infusion at 2 mg kg-1 h-1 until the end of surgery) or identical volumes and rates of saline. The primary outcome was the Quality of Recovery-15 score assessed 24 h after surgery. Secondary outcomes were areas under the pain numeric rating scale curve over time, 48-h morphine consumption, and adverse events.
RESULTS
Compared with saline, systemic lidocaine improved the Quality of Recovery-15 score 24 h postoperatively, with a median difference of 4 (95% confidence interval: 1-6; p = 0.015). Similarly, the area under the pain numeric rating scale curve over 48 h at rest and on movement was reduced in the lidocaine group (p = 0.004 and p < 0.001, respectively). However, these differences were not clinically meaningful. Lidocaine infusion reduced the intraoperative remifentanil requirements but not postoperative 48-h morphine consumption (p < 0.001 and p = 0.34, respectively). Additionally, patients receiving lidocaine had a quicker and earlier return of bowel function, as indicated by a shorter time to first flatus (log-rank p < 0.001), yet ambulation time was similar between groups (log-rank test, p = 0.11).
CONCLUSIONS
In patients undergoing laparoscopic colorectal surgery, intraoperative systemic lidocaine resulted in statistically but not clinically significant improvements in quality of recovery (see Graphical Abstract).Trial registration: Chinese Clinical Trial Registry; ChiCTR1900027635.
