  • Title: Pediatric extracorporeal cardiopulmonary resuscitation during nights and weekends.
    Author: Burke CR, Chan T, Brogan TV, McMullan DM.
    Journal: Resuscitation; 2017 May; 114():47-52. PubMed ID: 28263789.
    Abstract:
    AIM: Extracorporeal cardiopulmonary resuscitation (ECPR) is a lifesaving rescue therapy for patients with refractory cardiac arrest. Previous studies suggest that maintaining a 24/7 in-house surgical team may reduce ECPR initiation time and improve survival in adult patients. However, an association between cardiac arrest occurring during off-hours and ECPR outcome has not been established in children. METHODS: This is a single institution, retrospective review of all pediatric patients who received ECPR from December 2008 to August 2015. RESULTS: During the study period, ECPR was performed 54 times in 53 patients (20 weekday, 34 night/weekend). Interval from ECPR activation to initiation of extracorporeal life support was significantly longer during night/weekends (49min night/weekend vs. 33min weekday, p<0.001) as was the interval from ECPR activation to incision for cannulation (26min night/weekend vs. 14min Weekday, p<0.001). Rate of central nervous system (CNS) injury was higher in the night/weekend group (43% night/weekend vs. 15% weekday, p=0.04), with associated 75% mortality prior to hospital discharge. Time of arrest did not impact survival to hospital discharge (44% night/weekend vs. 55% weekday, p=0.57), one-year survival (33% night/weekend vs. 44% weekday, p=0.44), or neurologic outcome (Pediatric Cerebral Performance Score at 1-year post-ECPR, 1.45 weekday vs. 1.50 night/weekend, p=0.82). CONCLUSIONS: Cardiac arrest occurring at night or during weekend hours is associated with a longer ECPR initiation time and higher rates of CNS injury. However, prolonged pre-ECPR support associated with off-hours cardiac arrest does not appear to impact survival or functional outcome in pediatric patients.
