Therapeutic hypothermia is recommended for comatose adults after witnessed out-of-hospital cardiac arrest, but data about this intervention in children are limited.We conducted trial of two targeted temperature interventions at 38 children's hospitals involving who remained unconscious arrest. Within 6 hours the return circulation, patients were older than 2 days and younger 18 years age randomly assigned to therapeutic (target temperature, 33.0°C) or normothermia 36.8°C). The primary...

Extracorporeal membrane oxygenation (ECMO) is used for respiratory and cardiac failure in children but complicated by bleeding thrombosis.(1) To measure the incidence of (blood loss requiring transfusion or intracranial hemorrhage) thrombosis during ECMO support; (2) to identify factors associated with these complications; (3) determine impact complications on patient outcome.This was a prospective, observational cohort study pediatric, cardiac, neonatal intensive care units eight hospitals,...

Objective: To investigate significant new morbidities associated with pediatric critical care. Design: Randomly selected, prospective cohort. Setting: PICU patients from eight medical and cardiac PICUs. Patients: This was a randomly cohort of Measurements Main Results: The main outcomes measures were hospital discharge functional status measured by Functional Status Scale scores morbidity defined as an increase in the more than or equal to 3. Of 5,017 patients, there 242 (4.8%), 99 deaths...

Targeted temperature management is recommended for comatose adults and children after out-of-hospital cardiac arrest; however, data on in-hospital arrest are limited.In a trial conducted at 37 children's hospitals, we compared two interventions in who had arrest. Within 6 hours the return of circulation, older than 48 younger 18 years age were randomly assigned to therapeutic hypothermia (target temperature, 33.0°C) or normothermia 36.8°C). The primary efficacy outcome, survival 12 months...

Severity of illness measures have long been used in pediatric critical care. The Pediatric Risk Mortality is a physiologically based score to quantify physiologic status, and when combined with other independent variables, it can compute expected mortality risk morbidity risk. Although the ranges for variables not changed, recent data collection improvements made adapt new practice patterns, minimize bias, reduce potential sources error. These include changing outcome hospital survival/death...

Objective: Changes in technology and increased reports of successful extracorporeal life support use patient populations, such as influenza, cardiac arrest, adults, are leading to expansion support. Major limitations remain bleeding thrombosis. These complications the most frequent causes death morbidity. As a pilot project provide baseline data for detailed evaluation thrombosis current era, patients were analyzed from eight centers Eunice Kennedy Shriver National Institute Child Health...
