… To assess the effect of preoperative local anaesthesia with ropivacaine and find out if
there was a dose-response relationship with postoperative pain after inguinal hernia repair. …
Pain scores after 3 hours were significantly lower in the ropivacaine groups compared with
the saline group for all variables (p < 0.05). At 6 hours … Ropivacaine has a significant,
dose-related pain-reducing effect in the immediate postoperative period but we could find
no support for the theory that preoperative infiltration analgesia reduces long term pain. …

In a randomized, double-blind, placebo-controlled trial, we evaluated the use of
preoperative local anesthesia with regard to postoperative pain. Before surgery in 66
patients scheduled for cholecystectomy, the abdominal wall along the proposed line of
incision was infiltrated with 70 mL of 0.25% ropivacaine, 70 mL of 0.125% ropivacaine, or 70
mL of saline. Wound pain at rest, wound pain during mobilization, and pressure exerted to
reach maximum pain tolerance were assessed after 6, 26, 50, and 74 h and after 7 days …
