Abstract
Children who suffer cardiopulmonary arrest (CPA) after cardiac surgery frequently survive with return of spontaneous circulation. However, their neurodevelopmental outcomes and performance are still unclear. The aim of this study is to evaluate the midterm neurodevelopmental outcome and overall performance of children who survived CPA following cardiac surgery.
In this cohort study, we followed-up children who received cardiopulmonary resuscitation (CPR) post cardiac surgery during 2012–2013. We assessed their 5-year survival, functional, and neurodevelopmental outcomes using two performance scales: Pediatric Cerebral Performance Category (PCPC) and Pediatric Overall Performance Category (POPC). Both scales ranged from 1 for normal to 6 for brain death/death. We compared CPR group with a matching group (1:1) that had similar characteristics and conditions but no CPR.
Out of 758 postoperative cardiac children, 15 (2%) children had 19 episodes of CPA. Their median age was 10 months (0.5–168). Survival rates were 12/15 (80%) on hospital discharge and 10/15 (66%) after 5 years. Among 12 survivors, two patients (17%) scored 6, one (8%) scored 4, five (42%) scored 2, and four (33%) scored 1 on both PCPC and POPC. The median PCPC and POPC scores were [2, (interquartile range: 1–6) and 1, (interquartile range: 1–3, p = 0.018] for CPR and matching group, respectively. Regression analysis identifies duration of CPR, number of CPR session, and late-occurring CPA as risk factors for poor outcome.
Two-thirds of children requiring CPR post cardiac surgery survived after 5 years. Their neurodevelopmental and functional evaluation demonstrated worse outcome in comparison with their matching cases. CPR duration, number of CPA events, and late CPA were risk factors for poor outcome. Rehabilitation and special education programs might be needed for these groups of children with special needs.
