Randomized Controlled Trial Comparative Study Clinical TrialEfficacy of albuterol administered by nebulizer versus spacer device in children with acute asthma.
The aim of this study was to compare the response to inhaled albuterol after administration by nebulizer with the response after administration by a metered-dose inhaler and spacer device (MDI-spacer) to children with acute asthma. In a double-blind fashion, 33 children (6 to 14 years of age) with forced expiratory volume in 1 second (FEV1) between 20% and 70% of predicted values, and who were seen in the emergency department with acute asthma, were studied. They were treated with aerosolized albuterol or placebo by MDI-spacer, followed immediately by albuterol or placebo administered by nebulizer with oxygen. ⋯ Outcome measures included a clinical score, respiratory rate, arterial oxygen saturation, and FEV1, measured before and 10, 20, and 40 minutes after treatment. With the exception of heart rate (which increased in the nebulizer group and decreased in the MDI-spacer group (p < 0.05), no difference in the rate of improvement of clinical score, respiratory rate, arterial oxygen saturation, or FEV1 was noted during the 40-minute study period between children who received albuterol by nebulizer and those who received it by MDI-spacer. We conclude that spacers and nebulizers are equally effective means of delivering beta 2-agonists to children with acute asthma.

Comparative StudyPrevalence of urinary tract infection in febrile infants.
Urinary tract infection (UTI), a relatively common cause of fever in infancy, usually consists of pyelonephritis and may cause permanent renal damage. This study assessed (1) the prevalence of UTI in febrile infants (temperature > or = 38.3 degrees C) with differing demographic and clinical characteristics and (2) the usefulness of urinalysis in diagnosing UTI. We diagnosed UTI in 50 (5.3%) of 945 febrile infants if we found > or = 10,000 colony-forming units of a single pathogen per milliliter in a urine specimen obtained by catheterization. ⋯ Only 1 (1.6%) of 62 subjects with an unequivocal source of fever, such as meningitis, had UTI. As indicators of UTI, pyuria and bacteriuria had sensitivities of 54% and 86% and specificities of 96% and 63%, respectively. In infants with fever, clinicians should consider UTI a potential source and consider a urine culture as part of the diagnostic evaluation.

Clinical responses to prolonged treatment of persistent pulmonary hypertension of the newborn with low doses of inhaled nitric oxide.
We studied the efficacy of low-dose nitric oxide inhalation in nine consecutive patients with severe persistent pulmonary hypertension of the newborn (PPHN) who were candidates for extracorporeal membrane oxygenation (ECMO). All patients had marked hypoxemia despite aggressive ventilator management and echocardiographic evidence of pulmonary hypertension. Associated diagnoses included meconium aspiration syndrome (3 patients), sepsis (3 patients), and congenital diaphragmatic hernia (2 patients). ⋯ One patient with overwhelming sepsis had an initial improvement of oxygenation with nitric oxide but required ECMO for multiorgan and cardiac dysfunction. We conclude that low doses of nitric oxide cause sustained clinical improvement in severe PPHN and may reduce the need for ECMO. However, immediate availability of ECMO is important in selected cases of PPHN complicated by severe systemic hemodynamic collapse.

Comparative StudyPredictors of outcome of severe respiratory syncytial virus-associated respiratory failure treated with extracorporeal membrane oxygenation.
To examine the Extracorporeal Life Support Organization registry data base for all infants and children with respiratory syncytial virus-associated respiratory failure managed with extracorporeal life support, to delineate predictors of outcome. ⋯ Predictors of outcome of severe respiratory failure caused by respiratory syncytial virus infection managed with ECMO exist, and multivariate predictive models with high sensitivity and low false-positive risk are possible. Similar mathematical models may be helpful in establishing criteria for future trials of ECMO versus conventional respiratory support.
