Gall Bladder Bed Infiltration Analgesia

Overview

Early postoperative pain is a common complaint after elective laparoscopic cholecystectomy. Persistent acute postoperative pain is the dominating complaint and the primary reason for a prolonged stay after this procedure. This pain can be superficial incisional wound pain (somatic), deep visceral pain and/or post-laparoscopy shoulder pain (referred somatic), all of which may require systemic analgesia. Hypothesis: Laparoscopic pain can be superficial incisional wound pain (somatic pain), deep visceral pain and/or post-laparoscopy shoulder pain (referred somatic pain), so the block must be periportal for incisional wound pain, intraperitoneal to decrease pain caused by pneumoperitoneum, and of the bladder bed to decrease the deep visceral pain. This combination can give the maximum analgesia after laparoscopic cholecystectomy.

Bladder bed irrigation with Bupivacaine was an effective method for reducing pain during the first postoperative hours after laparoscopic cholecystectomy. The intraperitoneal administration of lidocaine solution (total dose, 3.5 mg/kg) will be done as follows: immediately after creation of the pneumoperitoneum, the surgeon will spray 50-75 ml of the total solution on the upper surface of the liver under the right sub-diaphragmatic space, and another 50-75ml of the total solution under the left sub-diaphragmatic space. In order to allow the sprayed solution to diffuse under the diaphragmatic space, the Trendelenburg position will be maintained for 2 minutes. In the infiltration group will be administrating 5 ml lidocaine at each port site before incision, then the surgeon will spray 50-75 ml of the total solution on the upper surface of the liver under the right sub-diaphragmatic space, and another 50-75ml of the total solution under the left sub-diaphragmatic space then 50 ml will be infiltrated in the bladder bed after clamping of the cystic duct and cystic artery. CO2 will be humidified and wormed.
