ABSTRACT
BACKGROUND:
To compare neonatal and pediatric resuscitation approaches to ventilation and chest compression by using either continuous chest compression with asynchronized ventilation (CCaV) or 31 CompressionVentilation ration (31 CV) during infant cardiopulmonary resuscitation. We hypothesized that 31 CV compared to CCaV will reduce time to return of spontaneous circulation (ROSC) in infantile piglets with asphyxia-induced bradycardic cardiac arrest.METHODS:
Twenty infantile piglets (5-10 days old) were anesthetized and asphyxiated by clamping the endotracheal tube. Piglets were randomized to 31 CV or CCaV for resuscitation (n = 10/group). Heart rate, arterial blood pressure, carotid blood flow, cerebral oxygenation, and respiratory parameters were continuously recorded throughout the experiment.RESULTS:
The median time (IQR) to ROSC among survivors was 157 (113-219) vs 421 (118-660) for 31 CV and CCaV, respectively (p = 0.253). The duration of resuscitation with 31 CV compared to CCaV was 206 (119-660) vs 660 (212-660)sec, respectively (p = 0.171). The number of piglets achieving ROSC with 31 CV and CCaV were 7/10 and 6/10, respectively (p = 1.00). There was no difference in hemodynamic and respiratory parameters between groups.CONCLUSIONS:
Time to ROSC and survival was not different between 31 CV and CCaV in infantile piglets. Either approach appears reasonable during infantile cardiopulmonary resuscitation. IMPACT Similar time to return of spontaneous circulation and survival with 31 CV and CCaV in infant piglets equivalent to 28-day-old children. Either approach appears reasonable during infantile cardiopulmonary resuscitation. Lack of scientific data to provide recommendations on when to switch between neonatal to pediatric resuscitation guidelines. No difference in time to return of spontaneous circulation or survival between 31 CV and CCaV in infantile piglets with asphyxia-induced bradycardic cardiac arrest. Both methods are viable options during infant cardiopulmonary resuscitation.
