ABSTRACT
OBJECTIVES:
To determine the incidence, risk factors and outcome of early postoperative arrhythmias in pediatric patients with congenital heart disease. MATERIAL ANDMETHOD:
A prospective study was conducted in every pediatric patient who consecutively underwent open-heart surgery at Siriraj Hospital from January 1st to December 31st, 2006. The collected data were demographic data, diagnosis, pre-operative arrhythmia, cardiac surgical data and continuous electrocardiographic monitoring data throughout the post operative intensive care period.RESULTS:
A total of 191 pediatric patients underwent cardiac surgery. Forty-five cases (23.5%) developed early post operative cardiac arrhythmias i.e. junctional ectopic tachycardia 18 cases (40%), heart block 7 cases (15.6%), supraventricular tachycardia 2 cases (4.4%). Cardiac arrhythmia occurred mostly within 24 hours after the operation. Patients with single ventricle physiology repaired developed the highest incidence of acute post operative arrhythmia (36.4%). Longer, cardiopulmonary bypass time- and redo-operation were the risk factors. Thirty-nine cases were treated with medications, 7 cases with temporary pacing, and 1 case with electrical cardioversion. Four patients needed long-term anti-arrhythmic agents. Cardiac arrhythmia played role in the causes of death in 2 cases (1.1% of total cases).CONCLUSIONS:
Post operative arrhythmias remained common and important complications of pediatric open-heart surgery. Long cardiopulmonary bypass time and redo-operation were risk factors for early post operative arrhythmia.
