Risk factors for prlonged length of stay in intensive care unit after congenital cardiac surgery in children

Objective:The prolonged length of stay in the intensive care unit after congenital heart disease surgery in children is related to considerable burden on the financial resources of hospitals,that the per-operative risk factors for prolonged stay in intensive care unit were discussed in this research.Methods: From May 2007 to March 2012,103 children,whose age less than 10 years old,under went congenital cardiac surgery,were analysed retrospectively.Univariate and multivariate analyses were performed for an intensive care unit stay over two days.Results: The length of intensive care unit stay(ICULOS) was(59.91±59.94)hours with a median of 44.00 hours,and there were four children who died.The risk factors influencing ICULOS with P0.05 in an univariate analysis were body weight,RACHS-1,Aristotle basic complexity score,the total operative time,cardiopulmonary bypass time,anesthesia time,early postoperative complications,and the duration of postoperative mechanical ventilation(P0.05).The independent risk factors identified by multivariate logistic regression analysis were cardiopulmonary bypass time and the duration of postoperative mechanical ventilation(P0.05).Conclusions: The length of intensive care unit stay may be shortend by enhanced maintainance and improvement for postoperative cardiac function,aggressive treatment of the early postoperative complications,and reducing the duration of postoperative mechanical ventilation,will create better early postopertive intensive care quality and better results may be achieved.
