Intraperitoneal Ropivacaine Irrigation in Bariatric Surgery

Using a standard irrigation device (no specific device is being used), 300 mg total of ropivacaine in 200ml normal saline will be instilled into the abdomen after surgical dissection, just before abdominal wall closure. Under direct visualization, the solution is delivered over the oesophageal hiatus, over both anastomoses and in both subdiaphragmatic spaces.
