Pulsed electromagnetic fields for post-appendicectomy pain management: a randomized, placebo-controlled trial.

Background: The value of pulsed electromagnetic field (PEMF) in postoperative pain management, due to the inconsistent findings so far, remains unclear. We extended the evaluation of PEMF on postoperative pain and intravenous (IV) analgesic use to a group of post-appendicectomy Asian patients.

Methods: This is a double-blinded, randomized trial.
