Muscle Relax Affects Outcomes of Robotic Surgery

During robotic laparoscopic surgery, a high intraperitoneal pressure may result in high airway pressure and inadequate perfusion of the abdominal organs, and as a result the postoperative outcomes. Degree of neuromuscular blockade (NMB) can affect the intraperitoneal pressure. In this study, the patients undergoing robotic laparoscopic surgery will be assigned to deep NMB group and moderate NMB group. Perioperative outcomes including maximal intraperitoneal pressure, maximal intraoptic pressure, quality of emergence, postoperative pain, and incidence of postoperative respiratory complication will be compared. The results of this study will provide evidence for optimizing NMB protocol of robotic laparoscopic surgery.
