Efficacité de l’infiltration cicatricielle subfasciale par la bupivacaïne dans la réduction de la douleur postopératoire des hernies inguinales

Introduction

The reduction of postoperative pain after surgery of inguinal hernia is an objective of lot of studies. The subfasciale infiltration of the wound may be an efficient technique.

Methods

This study was designed as a randomized, double blind, prospective study, comparing two treatment groups: a group infiltrated by bupivacaine (Gr B), and second one infiltrated by a placebo (Gr P). A part of demographic parameters and ASA class, the postoperative pain intensity at rest and at coughing, the morphine consumption and the secondary effects were compared. Patient's satisfaction and postoperative chronic pain at 3 and 6 months were also analyzed.

Results

Concerning demographic parameters, ASA class and secondary effects, we didn’t find any meaningful difference between the two groups. However, there was a significant reduction of postoperative pain in the bupivacaine group as well at rest as coughing. Gr P patients have more morphine consumption and they were unsatisfied and accused more chronic pain.

Discussion

Wound infiltration is still a simple and efficient technique in postoperative pain reduction. With this technique, hernia surgery may become ambulatory.
