Is Deep Neuromuscular Relaxation Beneficial in Laparoscopic, Abdominal Surgery?

Deep NMB significantly streamlines surgical conditions in laparoscopic surgery, similar to those in non-laparoscopic surgery. The clinical relevance is yet unclear. Deep neuromuscular relaxation just marginally improves space conditions in laparoscopic surgery using low-pressure capnoperitoneum (≤11 mmHg). In laparoscopic surgery, lower intra-abdominal pressure has no outcome-relevant advantage to higher intra-abdominal pressure. However, surgical conditions are impaired during low-pressure capnoperitoneum in comparison to routine-pressure capnoperitoneum (12-15 mmHg). Reduced postoperative pain scores have been observed during low-pressure capnoperitoneum, but the quality of evidence is rather poor.
