Nowadays, gynecologic surgeries are one of the most common procedures in the outpatient settings and are performed progressively with laparoscopy. However, acute pain is a most important postoperative complication and not only, can lead to patient discomfort and unsatisfying, but also result to delayed discharge, hospital admission and increased costs. Severity of post laparoscopic pain is moderate to severe and about 35% to 65% of patients experienced it as abdominal or shoulder tip pain and up to 80% of patients required analgesia. Lidocaine has antihyperalgic and anti inflammatory effects and use of this drug in the perioperative period can be a useful approach for post laparoscopic pain control.
After given informed consent, all patient's will randomly allocate in one of the lidocaine or placebo groups. With induction of anesthesia, lidocaine group will receive lidocaine infusion in the rate of 2mg/kg/h and placebo group will only receive normal saline in the same infusion rate. After completion of surgery and extubation, pain severity will be evaluate with visual analogue scale (VAS) scoring system in recovery and 2.4,6,12 and 24 hours postoperatively. Postoperative pain with VAS≥4 will be controlled with 0.5/kg intravenous Meperidine. Pain severity, time to first analgesic request, total analgesic consumption doses and any probable postoperative complications will be recorded and statistically analyzed.
