POST OPERATIVE ANALGESIA AFTER SPINAL ANAESTHESIA WITH MORPHINE AND BUPIVACAINE VERSUS FENTANYL AND BUPIVACAINE FOR UNILATERAL INGUINAL HERNIA REPAIR IN ADULT MALE : A COMPARATIVE STUDY

Abstract

Background: The study is aimed to compare the effects of intrathecal fentanyl and intrathecal morphine combined with 0.5% hyperbaric bupivacaine on the quality of postoperative pain control for unilateral inguinal hernia repair in adult male population. Fifty –ve patients aged 18-60 years with American Society of Anesthesiologists physical status I-IIMaterials and Methods: scheduled for elective inguinal hernia repair surgery were enrolled in this prospective randomized double blinded study. Patients received spinal anesthesia with either 25 mcg fentanyl plus 15 mg heavy bupivacaine intrathecally (group F, n=55) or 0.2 mg morphine plus 15 mg heavy bupivacaine intrathecally (group M, n=55).Hemodynamic parameters, time to rst analgesic requirement, postoperative pain scores, the number of analgesic requirements and side effects over postoperative 24 h were recorded Pain scores were signicantly lower in group MResults: compared with group F in the postoperative 24 h. The time to rst analgesic requirement was higher in group M than group F. Analgesic requirement was higher in group F than group M for the rst 24 hours, postoperative We concluded that the addition of 0.2 mgConclusion: morphine intrathecally to 15 mg heavy bupivacaine provides improved postoperative analgesia than 25 mcg fentanyl for inguinal hernia repair under spinal anesthesia.
