Pharmacopuncture with tramadol as preventive postoperative analgesia in inguinal herniorrhaphy

INTRODUCTION: studies have shown that over 40 % of patients suffer from pain in the immediate postoperative period, and three out of every four during the first two days. OBJECTIVE: evaluate the effectiveness of pharmacopuncture with tramadol to prevent postoperative pain in patients undergoing surgery for inguinal hernia. METHODS: a prospective descriptive randomized controlled study was conducted of 60 patients electively operated on for inguinal hernia at Dr. Carlos J. Finlay Central Military Hospital from September 2010 to September 2011. Patients were divided into two equal groups: Group F (study) received pharmacopuncture with tramadol 12.5 mg at stomach meridian acupoints (E36, E44) and regional subarachnoid anaesthesia, and Group C (control) received intramuscular tramadol 100 mg and the same anaesthetic procedure. Postoperative pain was ranked on the visual analog scale based on criteria provided by patients. RESULTS: there was a predominance of the male sex and the over-60 age group. Patients receiving anaesthesia-analgesia and pharmacopuncture showed greater postoperative analgesia, with total absence of pain in 60 %, less postoperative nausea and vomiting, and excellent hemodynamic stability. CONCLUSIONS: pharmacopuncture with tramadol constitutes an analgesic therapeutic method to prevent postoperative pain.
