Abstract |
Purpose : Early postoperative arrhythmias are a major cause of mortality and morbidity after open heart surgery in the
pediatric population. We evaluated the incidence and risk factors of early postoperative arrhythmias after surgery of congenital
heart disease.
Methods : From January 2002 to December 2008, we retrospectively reviewed the medical records of the 561 patients who
underwent cardiac surgery in Kyungpook National University Hospital. We analyzed patients' age and weight, occurrence
and type of arrhythmia, cardiopulmonary bypass (CPB) time, aortic cross clamp (ACC) time, and postoperative electrolyte
levels.
Results : Arrhythmias occurred in 42 of 578 (7.3%) cases of the pediatric cardiac surgery. The most common types of
arrhythmia were junctional ectopic tachycardia (JET) and accelerated idioventricular rhythm (AIVR), which occurred in 17
and 13 cases, respectively. The arterial switch operation (ASO) of transposition of the great arteries (TGA) had the highest
incidence of arrhythmia (36.4%). Most cases of cardiac arrhythmia showed good response to management. Patients with
early postoperative arrhythmias had significantly lower body weight, younger age, and prolonged CPB and ACC times (P
<0.05) than patients without arrhythmia. Although the mean duration of ventilator care and intensive care unit stay were
significantly longer (P <0.05), the mortality rate was not significantly different among the 2 groups.
Conclusion : Early postoperative arrhythmias are a major complication after pediatric cardiac surgery; however, aggressive
and immediate management can reduce mortality and morbidity. |
