OBJECTIVE: The goal of this study was to compare postoperative surgical site pain in gynecologic cancer patients who underwent elective extended lower midline laparotomy and managed their pain with either the ON-Q pain management system (surgical incision site pain relief system, ON-Q pump) or an intravenous patient-controlled analgesia pump (IV PCA). METHODS: Twenty gynecologic cancer patients who underwent elective extended lower midline laparotomy were divided into two groups. One group received a 72-hour continuous wound perfusion of the local anesthetic ropivacaine (0.5%, study group) into the supraperitoneal layer of the abdominal incision through the ON-Q pump. The other group received intravenous infusion pump of patient-controlled analgesia (fentanyl citrate 20 mg/mL · kg+ondansetron hydrochloride 16 mg/8 mL+normal saline). Postoperative pain was assessed immediately and at 6, 24, 48, 72, and 96 hours after surgery using the visual analogue scale. RESULTS: Postoperative surgical site pain scores at 24, 48, and 72 hours after surgery were lower in the ON-Q group than the IV PCA group. Pain scores at 24 hours and 48 hours after surgery were significantly different between the two groups (P=0.023, P<0.001). Overall painkiller administration was higher in the ON-Q group but this difference was not statistically significant (5.1 vs. 4.3, P=0.481). CONCLUSION: This study revealed that the ON-Q pain management system is a more effective approach than IV PCA for acute postoperative surgical site pain relief after extended lower midline laparotomy in gynecologic cancer patients.
