General laryngeal mask airway anesthesia with lumbar plexus and sciatic block provides better outcomes than general anesthesia and endotracheal intubation in elderly patients undergoing hip surgery

Abstract Objective To compare the perioperative outcomes and hemodynamic effects at induction of general laryngeal mask airway (LMA) anesthesia with lumbar plexus-sciatic nerve block (LPSB) and general anesthesia with endotracheal intubation (ET) in elderly patients undergoing hip surgery. Methods A total of 63 patients having open reduction internal fixation of an intertrochanteric fracture were randomly assigned to receive LMA anesthesia with LPSB or general anesthesia with ET. Perioperative and postoperative outcomes were compared between the 2 groups. Results Compared with the LMA/block group, there were significant reductions in systolic blood pressure, diastolic blood pressure, and mean arterial pressure at induction in the general endotracheal group (all, P  Conclusions General LMA anesthesia with LPSB provides better outcomes that general ET anesthesia in elderly patients undergoing hip surgery.
