Abstract
ImportancePatients with underlying cardiac disease form a considerable proportion of pediatric patients who experience in-hospital cardiac arrest. In pediatric patients after cardiac surgery, CPR with abdominal compressions alone (AC-CPR) may provide an alternative to standard chest compression CPR (S-CPR) with additional procedural and physiologic advantages. ObjectiveQuantitatively describe hemodynamics during cardiopulmonary resuscitation (CPR) and outcomes of infants who received only abdominal compressions (AC-CPR). DesignThis is a sub-group analysis of the prospective, observational cohort from the ICU-RESUS trial NCT028374497. Setting & PatientsA single site quaternary care pediatric cardiothoracic intensive care unit enrolled in the ICU-RESUS trial. Patients less than 1 year of age with congenital heart disease who required compressions during cardiac arrest. InterventionsUse of AC-CPR during cardiac arrest resuscitation. Measurements and Main ResultsInvasive arterial line waveforms during CPR were analyzed for 11 patients (10 surgical cardiac and 1 medical cardiac). Median weight was 3.3 kg [IQR 3.0, 4.0]; and median duration of CPR was 5.0 [3.0, 20.0] minutes. Systolic (median 57 [IQR 48, 65] mmHg) and diastolic (median 32 [IQR 24, 43] mmHg) blood pressures were achieved with a median rate of 114 [IQR 100, 124] compressions per minute. Return of spontaneous circulation was obtained in 9 of 11 (82%) patients; 2 patients (18%) were cannulated for extracorporeal cardiopulmonary resuscitation (ECPR) and 6 (55%) survived to hospital discharge with favorable neurologic outcome. ConclusionsAC-CPR may offer an alternative method to maintain perfusion for infants who experience cardiac arrest. This may have particular benefit in pediatric patients after cardiac surgery for whom external chest compressions may be harmful due to anatomic and physiologic considerations.
