Emergency and sub-emergency cardiac operations on congenital heart defects in children / 重庆医科大学学报

ABSTRACT

Objective:To summarize and evaluate emergency and sub-emergency cardiac operations on congenital heart defects in children.Method:From January 2002 to April 2008,emergency and sub-emergency cardiac operations were performed on 172 children(105 males,67 females) with critical congenital heart defects.The age was 5 days～33 months(mean 10.2 ? 8.7 months),and the weight was 2.7 ~13.6 kg(mean 8.2 ? 4.8 kg).Thepreoperative situation included recurrent respiratory infection or congestive heart failure(113 cases),severe hypoxemia(62 cases) and other critical conditions(5 cases).Corrective operations were performed on 149 cases and palliative operations on 23 cases.Results:The early postoperative mortality was 8.7%(15/172).The duration of intubation was 5 hours～31 days(mean 3.1?4.9 days),and the ICU stay time was 2 ~31 days(mean 5.8 ? 2.5 days).Postoperative low cardiac output syndrome was observed in 19 cases,atelectasis in 12 cases,lung infection in 35 cases,worsened pulmonary hypertension in 5cases,and pleural effusion in 5 cases.There were 2 late deaths during follow-up period of 2~73 months.The postoperative cardiac function of the 155 survivals was restored to grade I~II(NYHA).Conclusion:Emergency and sub-emergency cardiac operations on critical congenital heart defects in children are necessary and feasible.Good results can be achieved with appropriate perioperative management and surgical technique.
