Acute neurological injury in pediatric patients with single-ventricle congenital heart disease.

Objective: Single-ventricle congenital heart disease (CHD) in pediatric patients with Glenn and Fontan physiology represents a unique physiology requiring the surgical diversion of the systemic venous return from the superior vena cava (Glenn) and then the inferior vena cava (Fontan) directly to the pulmonary arteries. Because many of these patients are on chronic anticoagulation therapy and may have right-to-left shunts, arrhythmias, or lymphatic disorders that predispose them to bleeding and/or clotting, they are at risk of experiencing neurological injury requiring intubation and positive pressure ventilation, which can significantly hamper pulmonary blood flow and cardiac output. The aim of this study was to describe the complex neurological and cardiopulmonary interactions of these pediatric patients after acute central nervous system (CNS) injury.

Development of Care Curves Following the Stage 1 Palliation: A Comparison of Intensive Care Among 5 Centers.

Background Comparison of care among centers is currently limited to major end points, such as mortality, length of stay, or complication rates. Creating "care curves" and comparing individual elements of care over time may highlight modifiable differences in intensive care among centers. Methods and Results We performed an observational retrospective study at 5 centers in the United States to describe key elements of postoperative care following the stage 1 palliation.

Development of a Respiratory Support Score as a Visualization Tool in Intensive Care.

Background: In the modern era, many devices exist to support patients with respiratory insufficiency. There is currently no way to depict changes in the degree of support a patient is receiving over time.

Methods: We enrolled 4,889 subjects undergoing 5,732 cardiac surgical visits between 2011 and 2017 and extracted data elements related to respiratory support from the electronic medical record.
