Randomized Controlled Trial
Cooling for the reduction of postoperative pain: prospective randomized study.
Hernia surgery has been associated with severe pain within the first 24 h postoperatively. The application of cold or cryotherapy has been in use since at least the time of Hippocrates. The physiological and biological effects from the reduction of temperature in various tissues include local analgesia, inhibited oedema formation and reduced blood circulation. ⋯ Pain levels then gradually decreased for both the trial groups during the first 24 h postoperatively. There were significant differences in the VAS scores between the groups at 2, 6 and 24 h. We conclude that local cooling is a safe and effective technique for providing analgesia following inguinal hernia repair.
