[Multifactor analysis of postoperative mechanical ventilation supporting time in infants with congenital heart diseases].

Abstract

OBJECTIVE:

To analyze the multiple factors affecting the postoperative mechanical ventilation supporting time in infants less than 10 kg with simple congenital heart diseases and to seize time by the forelock of extube and improve the outcome of surgical treatment.

METHODS:

Data of 231 infants less than 10 kg with atrial septal defect(ASD),ventricular septal defect, and combining patent ductus arteriosus were retrospectively analyzed. The multivaricate stepwise logistic regression statistics were done for the predisposing factors affecting the ventilative supporting time.

RESULTS:

The ventilative supporting time was 3~375 (average 23.5 h) h. The multivaricate stepwise logistic regression analysis indicated that severe pulmonary hyperpressure, cross-cramp aortic time, cardiopulmonary bypass time, preoperational pulmonary infection, membrane oxygenator, modified ultrafiltration, weight, and postoperative complications were significantly correlated to the ventilative supporting time.

CONCLUSION:

Severe pulmonary hyperpressure, preoperational pulmonary infection, long cross-cramp aortic time, long cardiopulmonary bypass time, postoperative complications all prolong the ventilation supporting time; the use of membrane oxygenator and modified ultrafiltration during the operation and big weight can diminish the pulmonary complications and shorten the ventilation supporting time.
