OBJECTIVE To determine the eventual outcome of children with heart disease who had cardiopulmonary resuscitation (CPR) in a specialized pediatric cardiac intensive care unit (CICU), and to define the influence of any prearrest variables on the outcome. DESIGN A retrospective review of patients' medical records. SETTING A pediatric CICU of a tertiary(More)
The Pediatric Early Warning System (PEWS) score may be useful for detection of deterioration in clinical condition. In this retrospective study, the cases were patients transferred to the pediatric intensive care unit (PICU), and controls were those not transferred to the PICU. The maximum PEWS score in both groups were analyzed using Mann-Whitney U test(More)
OBJECTIVE To evaluate hemodynamic stability and gas exchange in a neonatal animal model of pumpless arteriovenous extracorporeal membrane oxygenation (AV-ECMO) with extracorporeal shunt flow of up to 15% of cardiac output during variable ventilation and oxygenation. DESIGN Prospective study. SETTING Research laboratory in a hospital. SUBJECTS Seven(More)
PURPOSE To evaluate the dosing and safety of intravenous magnesium sulfate administered via continuous infusion for refractory wheezing. MATERIALS AND METHODS All patients admitted to the pediatric intensive care unit (PICU) between January 1998 and March 2001 who were prescribed magnesium sulfate via continuous infusion were identified via retrospective(More)
STUDY OBJECTIVE To determine the rate, risk factors, and outcome of vancomycin-associated acute kidney injury (AKI) in critically ill children. DESIGN Retrospective cohort study. SETTING Tertiary care children's hospital. PATIENTS We reviewed the charts of children admitted to the pediatric intensive care unit during a 2-year period who were treated(More)
PURPOSE The criteria for starting extracorporeal membrane oxygenation (ECMO) therapy in term newborn patients with hypoxemic respiratory failure consist of an oxygenation index (OI) of 25 or higher and alveolar-arterial oxygen (Aao(2)) gradient of more than 600 at sea level. In such conditions, inhaled nitric oxide (iNO) may improve oxygenation and reduce(More)
BACKGROUND Splanchnic perfusion following hypovolemic shock is an important marker of adequate resuscitation. We tested whether the gap between esophageal partial carbon dioxide tension (PeCO2) and arterial partial carbon dioxide tension (PaCO2) is increased during graded hemorrhagic hypotension and reversed after blood reinfusion, using a fiberoptic carbon(More)
Objective: To test if hypothermia, induced by a sustained pentobarbital anesthesia, in rats can reduce ventilatory demands without compromising pulmonary gas-exchange efficiency. Design: Prospective study. Setting: Research laboratory in a hospital. Subjects: One group of 11 female Sprague Dawley rats. Interventions: The rats were anesthetized with 45 mg/kg(More)
INTRODUCTION Clinical application of arteriovenous (AV) extracorporeal membrane oxygenation (ECMO) requires assessment of cardiovascular ability to respond adequately to the presence of an AV shunt in the face of acute lung injury (ALI). This ability may be age dependent and vary with the experimental model. We studied cardiovascular stability in a lamb(More)
OBJECTIVE North America is home to 2 families of venomous snakes, Crotalinae (pit viper family) and Elapidae (coral snake family). Although there are several published reports describing and reviewing the management of pit viper snakebites in children, there are no recent similar publications detailing the clinical course and management of coral snake(More)
