Abstract:

Background: Endometriosis is routinely treated with laparoscopy, which despite significant advantages over laparotomy cannot diminish postoperative pain. Insufficient postoperative pain control decreases patient satisfaction.Objectives: This study was designed to evaluate the efficacy of intraperitoneal dexmedetomidine (DEX) combined with bupivacaine on postoperative pain in endometriosis laparoscopic surgery.Methods: Fifty-three patients with endometriosis, scheduled for laparoscopy in Rasoul-e-Akram Hospital, Tehran, from January 2016 to May 2017 who were randomly divided into three groups, including group 1 (G1, n = 21) received 50 mL intraperitoneal saline, group 2 (G2, n = 16) received 50 mL intraperitoneal instillation of bupivacaine 0.25%, and group 3 (G3, n = 16) received 50 mL bupivacaine 0.25% plus dexmedetomidine 1 μg/kg. Each patient with a history of allergy to local anesthetics or dexmedetomidine, cardiac disease, renal or hepatic failure, severe pulmonary disease; in addition, pregnant and comorbid obese patients were excluded from the study. Patients’ postoperative pain was assessed in the recovery room after 2, 6, 12, 24, and 48 hours using visual analogue scale (VAS). Total analgesic consumption was also recorded.Results: The postoperative VAS scores were significantly lower in group 3 than other groups in the recovery room, and 2, 6, 12, 24 and 48 hours after the surgery (P < 0.001). However, there was no significant difference between 1 and 2 groups. Furthermore, total VAS in the first 24 hours in group 3 was significantly lower than the two other groups (P < 0.001).Conclusions: We conclude 1 μg/kg intraperitoneal DEX administration combined with bupivacaine may prolong postoperative analgesia and decrease rescue analgesia requirement compared with bupivacaine alone
