Randomized Controlled Trial
Effects of deep neuromuscular blockade on the stress response during laparoscopic gastrectomy Randomized controlled trials.
Maintaining deep neuromuscular block during surgery improves surgical space conditions. However, its effects on patient outcomes have not been well documented. We examined whether maintaining deep neuromuscular blockade during surgery could decrease the stress response compared to moderate neuromuscular blockade. ⋯ A total of 96 patients were recruited and 88 (44 in each group) were included in the analyses. The levels of tumor necrosis factor-α and interleukin-1β measured at the end of surgery, interleukin-6 and interleukin-8 measured at 2 h postoperatively, and C-reactive protein measured at 48 h postoperatively were all significantly increased compared to the preoperative values, but there were no differences between the moderate and deep neuromuscular block groups. We found no differences in surgical stress response measured using determining levels of interleukin-6 and other mediators released between the moderate and deep neuromuscular blockade groups in patients undergoing laparoscopic gastrectomy.
