Efektivitas Magnesium Sulfat 30 mg/kgBB Intravena Dibanding dengan Fentanil 2 mcg/kgBB Intravena dalam Menekan Respons Kardiovaskular pada Tindakan Laringoskopi dan Intubasi

Abstract

Laryngoscopy and intubation are routine actions which cause the risk of cardiovascular responses, including increased blood pressure and heart rate, especially in high-risk patients such as patients with heart disorders. The aim of this study was to determine the effectiveness of intravenous MgSO4 30 mg/kgBW compared to that of intravenous fentanyl 2 mcg/kgBW in reducing cardiovascular responses to laryngoscopy and intubation to assess its possibility as an alternative drug. This study was a clinical trial with randomized double-blind controlled to 42 patients with physical status of the American Society of Anesthesiologists (ASA) I–II who underwent tracheal intubation under general anesthesia in Sanglah Denpasar Hospital Bali in the period of August–September 2014. Subjects were divided into two groups, MgSO4 30 mg/kgBW (n=21) and fentanyl 2 mcg/kgBW (n=21) groups. Changes in blood pressure and heart rate that occured before and after the action were recorded as research data. Data were analyzed with repeated ANOVA test, with p<0.05 considered significant. Statistical analysis showed that there was no significant difference between the two treatment groups. it is concluded that the administration of MgSO4 30 mg/kgBW is as effective as fentanyl 2 mcg/kgBW in reducing cardiovascular responses to laryngoscopy and intubation.
