Comparison of effects of the administration of intraperitoneal local anesthetics for postoperative analgesia and prevention of shoulder pain

Abstract

Postoperative abdominal and shoulder pain are common complications after laparoscopy. The aim of this study is to compare the effects of intraperitoneal local anesthetics on postoperative abdominal and shoulder pain after laparoscopy. 55 women, physical status ASA I, who were undergoing diagnostic or minor gynecologic surgery, was enrolled to the study. In Group 1 (Bupivacaine, n: 17) and Group 2 (Ropivacaine, n: 18), 80 ml solution which contains one of the local anesthetics (60 ml saline and 20 ml %0.5 bupivacaine in Group 1, 60 ml saline and 20 ml %0.75 ropivacaine in Group 2), was injected into the right subdiaphragmatic (30 ml) and abdominopelvic space (50 ml) at the beginning of the surgical procedure. Patients in Group 3 (Control, n: 20) didn't received any solution intraperitoneally. Shoulder and abdominal pain was assessed with a visual analogue scale, and any other complications were noted during the first 24 hours after surgery. Shoulder and abdominal pain intensity and frequency were significantly less in the local anesthetic groups than control group, similar between ropivacaine and bupivacaine groups.
