The effect of fentanyl addition to bupivacaine on shivering and vomiting nausea in patients undergoing femoral fracture surgery by spinal anesthesia: A double-blind randomized clinical trial

Abstract

(n = 20). There was no significant difference between fentanyl and bupivacaine in terms of recovery from nausea and postoperative times (p> 0.05) and differences between bupivacaine-fentanyl and bupivacaine in shivering at 6, 12, 18 and 24 hours postoperatively. There was no significant (p> 0.05).
