[Techniques and experience which improve the surgical outcomes of critical and complex congenital heart disease in neonates].

Objective: To discuss the experience of early surgical intervention to critical and complex congenital heart diseases (CHD) in neonates. Methods: A retrospective study of clinical records of patients with congenital heart diseases underwent surgical intervention in one single pediatric cardiac center was performed. From January 2009 to December 2017, 841 critical and complex CHD neonates were identified at Department of Cardiovascular Surgery, Children's Hospital of Fudan University, of which 6.5% were premature. There were 557 male and 284 female patients. The age was (11±9) days, ranging from 0 to 28 days, M ( Q(R) ): 8(17) days. The weight was (3.26±0.57) kg, ranging from 1.9 to 5.0 kg, M ( Q(R) ): 3.3(0.7) kg. There were 189 patients associated with other malformation besides CHD. Before surgery, 13.6% (114/841) patients were on ventilation, and severe acidosis was addressed in 136 patients. All patients underwent surgical interventions, including surgical procedures and hybrid procedures. Results: Emergency surgeries were performed in 35 patients. One hundred patients had palliative procedures, other 633 patients had complete repair, while the rest 108 patients underwent hybrid procedures. The in-hospital mortality was 4.0% (34/841). The ventilation time was 1.5 to 1 130.0 hours, M ( Q(R) ): 94 (116) hours, with the rate of reintubation 3.3% (27/807). The ICU stay time was 1 to 195 days, M ( Q(R) ): 14 (15) days. Conclusion: The improvement on early screening and diagnosing, referral system, multidisciplinary cooperation and hybrid invention skills together contributed to better outcomes of critical and complex congenital heart diseases in neonates.
