Clinical Efficacy of Intravenous Administration of Amiodarone in the Treatment of Postoperative Heart Failure Combined with Ventricular Tachycardia

OBJECTIVE:To observe the effect of intravenous administration of amiodarone on postoperative heart failure and ventricular arrhythmia.METHODS:A total of 42 postoperative heart failure patients with ventricular tachycardia and multi-source ventricular premature beat were treated with lidocaine,but clinical efficacy was not obtained.Those patients received intravenous administration of diluted amiodarome 150 mg.After 30 minutes the dose of amiodarone was kept at 0.5～1.0 mg·min-1,and the total dosage ranged from 1 000 mg to 1 200 mg within 24 h.Clinical symptoms were recorded in every hour,such as cardiac rhythm,heart rate,blood pressure,heart failure.RESULTS:After 24 h of treatment,17 cases of ventricular arrhythmia had apparent effect(40%),20 cases of partial effect(47%),5 cases of no effect(12%),there were statistical significance in difference before and after treatment(P0.05).The improvement of heart function was significantly different before and after treatment(P0.05).CONCLUSION:Intravenous administration of amiodarone has effect on postoperative heart failure and ventricular arrhythmia,and is beneficial to the improvement of cardiac function.
