[Management by hypothermia of junctional ectopic tachycardia appearing after pediatric heart surgery].
Junctional ectopic tachycardia (JET) is a complication of the repair of congenital cardiac malformations that responds poorly to conventional treatment. We report our experience with the use of moderate hypothermia in its management. Twelve infants with postoperative JET treated with hypothermia were reviewed. The mean interval between the diagnosis of JET and initiation of hypothermia was 1.5 0.5 hours. In the first 24 hours of hypothermia, central temperature and heart rate decreased significantly. Arterial pressure and diuresis tended to increase and central venous pressure tended to decrease. No direct adverse events occurred. All the patients but one survived and are alive and free of neurological deficits after 15 12 months.
