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.
