Abstract

Objective: This study was performed compare the effectiveness of oxycodone and fentanyl in reducing the incidence and severity of etomidate-induced myoclonus. Methods: In total, 162 patients with an American Society of Anesthesiologists physical status of I or II were assigned at random to three groups. Patients assigned to Group O received 0.1 mg/kg of oxycodone (n = 54), those assigned to Group F were given 1 µg/kg of fentanyl (n = 54), and those assigned to Group S were given an equal volume of saline intravenously 2 minutes prior to administration of 0.3 mg/kg of etomidate (n = 54). The incidence and severity of myoclonus was evaluated 2 minutes after etomidate administration. The patients' vital signs, coughing, nausea, dizziness, and other related adverse reactions were also recorded. Results: The incidence of myoclonus was significantly lower in Group O (0.0%) than in Group F (31.5%) and Group S (72.2%); the intensity was also lowest in Group O. All patients in each group had stable cardiovascular profiles. Conclusions: Intravenous injection of 0.1 mg/kg of oxycodone 2 minutes prior to etomidate is more effective in preventing etomidate-induced myoclonus during general anesthesia than is 1 µg/kg of fentanyl.
