Mortality risk factors of a pediatric population with fulminant hepatic failure undergoing orthotopic liver transplantation in a pediatric intensive care unit.
To determine risk factors of mortality in the preoperative, perioperative, and immediate postoperative period of a pediatric population that has undergone orthotopic liver transplantation for fulminant hepatic failure in a pediatric intensive care unit. DESIGN: Retrospective review of medical records. SETTING: A pediatric intensive care unit in a children's hospital. PATIENTS: Sixty patients with fulminant hepatic failure who fulfilled King's College criteria for liver transplantation. INTERVENTION: Orthotopic liver transplantation was performed according to standard techniques. Before transplantation, patients were admitted to a pediatric intensive care unit when intensive care was required, and patients were always admitted to a pediatric intensive care unit after the operation. Measurements: A total of 20 variables were studied via univariate and multivariate analysis; statistical significance was accepted when p

Economically disadvantaged children receive less preventive asthma care and more inpatient care. Studies have not evaluated the association of insurance status on children with severe exacerbations. We evaluated differences in severity of illness, resource use, and outcome associated with Medicaid insurance among children receiving intensive care for asthma. DESIGN: Retrospective cohort study. SETTING: Fourteen American pediatric intensive care units participating in the Pediatric Intensive Care Evaluations database. Methods: Patients with a primary diagnosis of asthma treated from May 1995 to February 2000 were identified. Demographic information and clinical data were evaluated to determine whether there was an association between Medicaid insurance, severity of illness, and length of stay. ⋯ Asthmatic children receiving Medicaid had longer pediatric intensive care unit and hospital stays and an increased risk of mechanical ventilation compared with asthmatic children with commercial or health maintenance organization insurance. Further studies are needed to evaluate differences in outcome and resource utilization for economically disadvantaged asthmatic children.

Risk factors prolonging ventilation in young children after cardiac surgery: Impact of noninfectious pulmonary complications.
To determine risk factors for prolonged ventilation after cardiac surgery in young children and assess the impact of noninfectious pulmonary complications on ventilatory duration. DESIGN: Retrospective case series analysis. SETTING: A tertiary pediatric cardiac center. PATIENTS: Clinical records of 222 consecutive children aged

Corticosteroids for the prevention of reintubation and postextubation stridor in pediatric patients: A meta-analysis.
To determine whether corticosteroids are effective in preventing or treating postextubation stridor and in reducing the need for subsequent reintubation of the trachea in critically ill infants and children. DESIGN: Meta-analysis of published randomized controlled trials. DATA SOURCES: References of each trial from a MEDLINE search were reviewed, and experts in the field were contacted. STUDY SELECTION: Any randomized controlled trial comparing the administration of corticosteroids with placebo on the prevalence of reintubation or postextubation stridor in infants or children receiving mechanical ventilation via an endotracheal tube in an intensive care unit. DATA EXTRACTION: Data extraction and methodologic quality assessment were assessed independently by two reviewers. DATA SYNTHESIS: Six controlled clinical trials met the criteria for inclusion; three trials pertain to neonates and three to children. Five trials examined the use of steroids for the prevention of reintubation (four of these evaluated postextubation stridor specifically); one trial examined the use of steroids to treat existing postextubation stridor in children. There was a nonsignificant trend toward a decreased rate of reintubation in all subjects when prophylactic steroids were used (n = 376, relative risk [RR] = 0.34, 95% confidence interval [CI] = 0.05-2.33). Prophylactic use of steroids reduced postextubation stridor in the pooled studies (n = 325, RR = 0.50, 95% CI = 0.28-0.88). In young children, there were significant reductions of postextubation stridor with preventive treatment (n = 216, RR = 0.53, 95% CI = 0.28-0.97), and a trend toward less stridor was observed in neonates (n = 109, RR = 0.42, 95% CI = 0.07-2.32). There was a nonsignificant trend toward a reduced reintubation rate when steroids were used to treat existing upper airway obstruction requiring reintubation (RR = 0.55, 95% CI = 0.17-1.78). Side effects were seldom reported and could not be evaluated. ⋯ Prophylactic administration of dexamethasone before elective extubation reduces the prevalence of postextubation stridor in neonates and children and may reduce the rate of reintubation.

Comparison of end-tidal CO2 and Paco2 in children receiving mechanical ventilation.
To determine whether end-tidal CO(2) (Petco(2)) measurement provides a reliable estimate of ventilation in critically ill children who are mechanically ventilated. DESIGN: Prospective, nonrandomized, consecutive enrollment study. SETTING: A university-affiliated children's hospital pediatric intensive care unit. PATIENTS: All intubated, mechanically ventilated pediatric patients. INTERVENTIONS: All Petco(2)-Paco(2) pairs were from patients ventilated with a Servo 300 Ventilator (Siemens-Elema AB, Stockholm, Sweden). When a blood gas sample was obtained, Petco(2) as measured by a continuous mainstream Petco(2) capnograph was recorded. Measurements: The results of blood gas measurements and corresponding Petco(2) measurements were recorded. Demographic data and primary diagnosis were noted. Petco(2)-Paco(2) pairs obtained from patients with intracardiac shunts or obtained during high-frequency oscillation or extracorporeal membrane oxygenation at the time of measurement were excluded from analysis. Linear regression was used to analyze Petco(2)-Paco(2) pairs. Repeated measure analysis of variance with the mixed-model algorithm in SAS software (SAS Institute, Carey, NC) was used to analyze the trend in the Petco(2) and Paco(2) relationship. Chi-square was used to analyze categorical data. Statistical significance was considered p <.05. ⋯ In most intubated, mechanically ventilated infants and children, Petco(2) reliably estimates ventilation.
