Hyperoxia During Cardiopulmonary Bypass Is Associated With Mortality in Infants Undergoing Cardiac Surgery.
Patients undergoing cardiac surgery using cardiopulmonary bypass have variable degrees of blood oxygen tension during surgery. Hyperoxia has been associated with adverse outcomes in critical illness. Data are not available regarding the association of hyperoxia and outcomes in infants undergoing cardiopulmonary bypass. We hypothesize that among infants undergoing cardiac surgery, hyperoxia during cardiopulmonary bypass is associated with greater odds of morbidity and mortality. ⋯ Hyperoxia occurred in a substantial portion of infants undergoing cardiopulmonary bypass for cardiac surgery. Hyperoxia during cardiopulmonary bypass was an independent risk factor for mortality and may be a modifiable risk factor. Furthermore, hyperoxia during cardiopulmonary bypass was associated with four-fold greater odds of mortality within 30 days of surgery. Hyperoxia failed to identify an association with development of acute kidney injury or prolonged postoperative length of stay when controlling for covariables. Validation of our data among other populations is necessary to better understand and elucidate potential mechanisms underlying the association between excess oxygen delivery during cardiopulmonary bypass and outcome.

Observational StudyUltrasound-Guided Postpyloric Feeding Tube Placement in Critically Ill Pediatric Patients.
Various methods to insert postpyloric feeding tubes at the bedside have been reported, but the optimal method remains controversial. The objective of this study was to evaluate the effect of ultrasound-guided postpyloric feeding tube placement in critically ill children. ⋯ In this single-center study, ultrasound-guided postpyloric feeding tube placement was feasible and a significantly high first-pass success rate was observed for critically ill children. Additional investigation with a larger pool of operators and randomized controlled patient assignment is required.
