Analgesic Effect of Nebulized Versus Intravenous Fentanyl for Pain Relief of Limb Fracture: A Double-Blind Clinical Trial

Abstract

Method: The present double-blind clinical trial recruited 213 patients presenting with fractured limbs to emergency departments. The first group of patients received 1 micg/kg of intravenous fentanyl citrate from a solution of 50 micg/ml and 5 ml of normal saline in nebulized form (group A), and the second group intravenously received 5 ml of normal saline and 4 micg/kg of 50 micg/ml solution of fentanyl citrate in nebulized form, whose volume reached 5 ml with the addition of normal saline (group B). Then, pain level was frequently measured and compared in the two groups for 20 minutes.
