Abstract/OtherAbstract:
OBJECTIVE: Deep hypothermic circulatory arrest (DHCA) and antegrade cerebral perfusion (ACP) are 2 cardiopulmonary bypass techniques applied in aortic arch repair. In recent literature, cerebral effects of both techniques have received most attention, whereas the consequences for other organs have not been thoroughly investigated. Therefore, in this study, the impact of duration of DHCA and ACP on postoperative recovery was analyzed in a cohort of neonates undergoing aortic arch reconstruction. METHODS: All consecutive neonates who underwent aortic arch reconstruction from 2004 to 2009 were included in this retrospective study. Length of stay on the intensive care unit (ICU-LOS), duration of mechanical ventilation, inotrope score, and areas under the curve (AUC) for lactate and creatinine were compared with respect to durations of DHCA and ACP, respectively. Correction for confounders was performed using multivariable linear regression. RESULTS: Eighty-three neonates were included, with a 30-day mortality of 4.8%. Longer duration of DHCA was associated with longer ICU-LOS both in univariable and multivariable analyses. Similarly, duration of mechanical ventilation and lactate and creatinine AUCs increased with duration of DHCA. Inotrope score was only associated with DHCA duration in univariable analysis. Duration of ACP did not affect any of the outcome parameters. CONCLUSIONS: Increasing duration of DHCA, but not ACP, during neonatal aortic arch reconstruction prolongs short-term postoperative recovery. This suggests all efforts should be made to reduce the duration of DHCA to the shortest period possible, which may be achieved by exclusive use of ACP or a combination of the 2 perfusion techniques.
