Randomized Controlled Trial Multicenter Study Clinical TrialRandomized, multicenter trial of inhaled nitric oxide and high-frequency oscillatory ventilation in severe, persistent pulmonary hypertension of the newborn.
Although inhaled nitric oxide (iNO) causes selective pulmonary vasodilation and improves oxygenation in newborn infants with persistent pulmonary hypertension, its effects are variable. We hypothesized (1) that the response to iNO therapy is dependent on the primary disease associated with persistent pulmonary hypertension of the newborn (PPHN) and (2) that the combination of high-frequency oscillatory ventilation (HFOV) with iNO would be efficacious in patients for whom either therapy alone had failed. ⋯ We conclude that treatment with HFOV plus iNO is often more successful than treatment with HFOV or iNO alone in severe PPHN. Differences in responses are partly related to the specific disease associated with PPHN.

Multicenter StudyProspective multicenter study of sulfonylurea ingestion in children.
Sixty-eight percent of pediatric sulfonylurea ingestions reported to poison centers do not result in laboratory or behavioral effects. Consequently, if all exposed children are admitted overnight or for 24 hours for these exposures, it will result in 600 to 700 hospital admissions per year of children who will remain free of symptoms. We prospectively studied exposures reported to 10 regional poison centers to determine if it were possible to differentiate those patients who would have symptoms from those who would remain symptom free. ⋯ A lack of onset of hypoglycemia (BG > 60 mg/dl) in the first 8 hours after ingestion is predictive of a benign outcome in accidental pediatric sulfonylurea ingestion. Clinical observation of children for onset of hypoglycemia during oral feeding alone appears safe. Some children with symptoms of hypoglycemia need to receive intravenous dextrose therapy. Time of day of ingestion is not predictive of risk of hypoglycemia. Finally, at this time it appears inappropriate to use a milligram per kilogram body weight dose as a guide for management decisions.
