Cerebral hypoxia-ischemia remains a complication in children with congenital heart disease. Near-infrared spectroscopy can be utilized at the bedside to detect cerebral hypoxia-ischemia. This study aimed to calibrate and validate an advanced technology near-infrared cerebral oximeter for use in children with congenital heart disease. ⋯ This cerebral oximeter accurately measures the absolute value of cerebral saturation in children over a wide range of oxygenation and subject characteristics, offering advantages in assessment of cerebral hypoxia-ischemia in congenital heart disease.

Lower extremity ischemia is an important source of morbidity with femoral venoarterial extracorporeal membrane oxygenation support. We describe our experience with the use of a side-arm graft sewn to the femoral artery that facilitates adequate extracorporeal membrane oxygenation flow while preventing lower extremity ischemia.

As overall mortality rates have fallen in pediatric cardiac surgical procedures, complication monitoring is becoming an increasingly important metric of patient outcome. Currently there is no standardized method available to monitor severity-adjusted complications in congenital cardiac surgical procedures. ⋯ The O:E plot provides a simple and effective system to monitor complication rates over time based on severity-adjusted complication data. Grouping complications into classes allows us to identify specific subsets of complications that can be focused on to improve patient outcomes.

The RIFLE criteria (risk, injury, failure, loss, and end-stage kidney disease) have been used to assess acute kidney injury (AKI) in various populations of critically ill children. There are limited reports of AKI using RIFLE criteria in large pediatric populations undergoing congenital heart disease surgery. ⋯ Incidence of AKI based on RIFLE criteria in patients undergoing congenital heart disease surgery is higher than previously reported. Risk factors include age 1 month or younger and use of cardiopulmonary bypass. Acute kidney injury is associated with longer lengths of stay.

Respiratory support with venovenous extracorporeal membrane oxygenation during stenting of tracheobronchomalacia.
A subset of patients with severe airway disease cannot be adequately supported with conventional mechanical ventilation during complex airway procedures. We report the successful respiratory support of a patient with severe tracheobronchomalacia with venovenous extracorporeal membrane oxygenation during rigid bronchoscopy with stent removal and stent placement.
