| Abstract | ||
| Background: Laparoscopic surgery is gaining popularity so different modalities of pain management should be used as patients experience postoperative pain of different sources especially from the abdomen, back and shoulder region which is severe especially in first postoperative hours. Objective: We aimed to evaluate effect of intraperitoneal instillation of ketamine and normal saline on post- operative pain and analgesic requirements after laparoscopic cholecystectomy. Patients and Methods: Forty patients undergoing laparoscopic cholecystectomy were randomly allocated and divided into two groups, The ketamine intraperitoneal (KIP) group (n=20 patients), in which 0.5 mg/kg ketamine diluted in 30 ml normal saline was instilled intraperitoneally,The saline intraperitoneal (SIP) group (n=20 patients), in which 30 ml of normal saline was instilled intraperitoneally. Patients receive these drugs as follow, 16 ml in gall bladder fossa while other 14 ml under copula of diaphragm on both sides while patients were placed in 15-20-degree trendelenburg position. This was done before patients recovered from anesthesia, then patients extubated and transferred to ward. Patients were evaluated according to VAS, time to first analgesic and total analgesic requirements during 24 hours post-operative. Results: Our results showed that usage of ketamine decreases postoperative pain and analgesic consumption in the first 24 hours after surgery along with longer pain free period compared to patients who were given bupivacaine after laparoscopic cholecystectomy. In our study ketamine 0.5mg/kg was safely used as we did not observe any sign of toxicity. Conclusion: Intraperitoneal instillation of local anesthetic is an easy, cheap and safe method which provides good analgesia in the immediate postoperative period after laparoscopic surgery. Ketamine is highly effective in postoperative pain control in laparoscopic cholecystectomy without any hazards on patients. | ||
