Randomized Controlled Trial
A double-blinded, prospective randomized controlled trial of intraperitoneal bupivacaine in laparoscopic Roux-en-Y gastric bypass.
Intraperitoneal local anesthetics have been investigated in several laparoscopic procedures that demonstrate improved postoperative pain control and reduced length of hospital stay. No published studies to date address the effectiveness of IP local anesthetics in laparoscopic gastric bypass patients (LRYGB). ⋯ IPB use during LRYGB revealed a statistically significant difference only in postoperative oral narcotic use. Possibly, the IPB can limit or prevent peritoneal irritation and reduce the need for longer narcotic use. Clinical significance was not demonstrated by our outcomes variables.
