Survival after extracorporeal cardiopulmonary resuscitation in infants and children with heart disease.
We investigated survival and predictors of mortality for infants and children with heart disease treated with extracorporeal membrane oxygenation as an aid to cardiopulmonary resuscitation. ⋯ Use of extracorporeal membrane oxygenation as an adjunct to cardiopulmonary resuscitation resulted in hospital survival in 42% of infants and children with heart disease. Underlying cardiac physiology and associated cardiac surgical procedures influenced mortality, as did pre-extracorporeal resuscitation status and extracorporeal membrane oxygenation-associated complications.

Comparative StudyThe influence of seasonal variation on cardiac surgery: a time-related clinical outcome predictor.
The effect of seasonal variation on cardiac surgery outcomes is unknown. We investigated the effect of season on risk-adjusted hospital mortality and length of stay. ⋯ Cardiac surgery outcomes are influenced by the time of year. Hospital mortality and intensive care unit stay after coronary artery bypass grafting were increased during the winter season compared with the rest of the year.

Regional differences in tissue oxygenation during cardiopulmonary bypass for correction of congenital heart disease in neonates and small infants: relevance of near-infrared spectroscopy.
Cardiac surgery with cardiopulmonary bypass for correction of congenital heart disease in neonates and small infants is associated with considerable neurologic sequelae. We assessed the extent to which mixed venous oxygen saturation as a measure for adequacy of perfusion, reflects the oxygenation status of upper and lower body compartments. Moreover, we evaluated potential benefits of near-infrared spectroscopic monitoring of regional tissue oxygenation. ⋯ In neonates and small infants undergoing cardiac surgery with cardiopulmonary bypass, considerable regional differences exist in venous oxygen saturation. Mixed venous oxygen saturation primarily represents lower-torso oxygen status but poorly reflects and systematically overestimates upper-body oxygenation. Near-infrared spectroscopy yields additional information on regional oxygenation and may be valuable in early and sensitive detection of regional malperfusion in critical organs such as the brain.
