Local Anesthetic Continuous Preperitoneal Infiltration and Wound Hyperalgesia - Full Text View

Purpose

In this multicenter, randomised, placebo-controlled, double-blind trial, hyperalgesia area around the scarce following colorectal laparoscopic surgery (piece removal) will be assessed in 3 groups of patients : group 1: continuous ropivacaine preperitoneal infusion, group 2 : intravenous lidocaine infusion, or group 3 : control group without local anesthetics. All patients will receive parenteral analgesia combining acetaminophen and morphine.
