Although laparoscopic surgery is known to cause less postoperative pain when compared to laparotomy, some patients still suffer from excessive pain, especially during the first stages of recovery. The purpose of our study was to assess the effect of intraperitoneal nebulization of lidocaine during gynecological laparoscopic procedures on perioperative pain. The study was a prospective, randomized, double-blinded, placebo-controlled trial (Canadian task force classification I) that included 23 patients who underwent outpatient gynecological laparoscopic procedures. Patients were randomly assigned either to a study group that received 5 mg/kg of lidocaine intraperitonealy during surgery (n=15) or to a control group that received sterile water in the same manner (n=8). The fluid was infuslated along with the CO2 through a Insuflow® device. All patients received the same anesthetic technique. Intraoperative pain as assessed by changes in the vital signs was treated with fentanyl. Postoperative pain was evaluated according to postoperative opioid requirements and by the Visual Analogue Scale (VAS) at 15 min, 1 h and 24 h postoperatively. The VAS score was found to be lower for the study group 1 h after surgery (p=0.023). There was no difference in the VAS scores at 15 min (p=0.9) and 24 h (p=0.11) after surgery. A correlation analysis showed no association between the amount of lidocaine insufflated and the severity of the postoperative pain. There was no difference in terms of fentanyl administration during surgery or opiod consumption following surgery between the groups. We concluded that continuous intraperitoneal insuflation of lidocaine using an Insuflow® device may significantly reduce pain in the initial stage of postoperative recovery.
