"Pain control during the first 24 hours after laparoscopic surgery is of particular importance. Different methods for this purpose are listed that include the intraperitoneal administration of Morphine, Bupivacaine, Lidocaine, etc. The aim of this study is prevalence of intraperitoneal administration of Lidocaine on pain and shoulder pain in the postoperative, in patients undergoing elective laparoscopic cholecystectomy surgery. This study was a double blind clinical trial on 80 patients that were for elective laparoscopic cholecystectomy surgery. They were divided randomly into two groups of 40 numbers that in the first group after laparoscopy and before leaving the trocar, 100 cc Normal Saline containing 200 mg of Lidocaine in the diaphragm, and peritoneal cavity was sprayed and in the second group only 100 cc of Normal Saline was sprayed into the abdomen. After the surgery abdominal pain and shoulder pain ruler of patients with pain (10.1) hours, 1, 2, 4, 6, 12, 18 and 24 were measured. The mean age in the saline group was 40.92±14.28 and in Lidocaine group was 43.95±17.79 (P=0.404). The mean weight in the saline group was 67.58±12.92 and in Lidocaine group was 68.65±11.7 (P=0.698). Results did not show the difference between the two groups in terms of sex, age and weight. The mean pain in 24 hours in normal saline group was 4.15±1.22 and in Lidocaine group was 1.52±0.63 (P=0.194). Nausea, vomiting, dizziness, Tinnitus and numbness around the mouth in both groups, at different times did not show a statistically significant difference. Tranquilizer intake for 1, 4, 6, 12 and 24 days after surgery in Lidocaine group compared with Normal Saline group was less but the difference was not significant. Intraperitoneal administration 200 mg Lidocaine in patients undergoing surgery elective laparoscopic cholecystectomy is not effective in reducing pain and shoulder after surgery."
