Details and patient eligibility

About

Objectives: For major laparoscopic surgery, as with open surgery a multimodal analgesia plan can help control postoperative pain. Placing a wound catheter intraoperatively following colon surgery could optimize the control of acute pain with less consumption of opioids and few adverse effects.

Methods: We conducted a prospective, randomized, study of 103 patients scheduled to undergo laparoscopic colon surgery for cancer in Galdakao-Usansolo Hospital.

Patients were recruited and randomly allocated to wound catheter placement plus standard postoperative analgesia or standard postoperative analgesia alone. A physician from the acute pain management unit monitored all patients for at multiple points over the first 48 hours after surgery. The primary outcome variables were verbal numeric pain scale (NRS) scores and amount of intravenous morphine used via patient controlled infusion.
