Randomized Controlled Trial Comparative Study Clinical TrialComparison of morphine and methadone for prevention of postoperative pain in 3- to 7-year-old children.
A randomized, double-blind, prospective study was performed to determine the effects of perioperative administration of morphine or methadone on postoperative analgesic requirements and pain scores in 35 children aged 3 to 7 years undergoing major surgery. After a standardized induction of anesthesia, methadone or morphine, 0.2 mg/kg, was blindly administered, and supplemental doses were titrated to achieve comfort in the recovery room. Pain was assessed during the next 36 hours with a combination of validated behavioral and self-report measures. ⋯ No patient had prolonged emergence from anesthesia, and no patient required naloxone or postoperative ventilatory assistance. No major adverse events occurred. We conclude that perioperative intravenous administration of methadone is an effective, inexpensive, and technologically simple means for providing prolonged analgesia for children after surgery.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialMulticenter controlled trial comparing high-frequency jet ventilation and conventional mechanical ventilation in newborn infants with pulmonary interstitial emphysema.
One hundred forty-four newborn infants with pulmonary interstitial emphysema were stratified by weight and severity of illness, and randomly assigned to receive treatment with high-frequency jet ventilation (HFJV) or rapid-rate conventional mechanical ventilation (CV) with short inspiratory time. If criteria for treatment failure were met, crossover to the alternate ventilatory mode was permitted. Overall, 45 (61%) of 74 infants met treatment success criteria with HFJV compared with 26 (37%) of 70 treated with CV (p less than 0.01). ⋯ When survival resulting from rescue by the alternate therapy in crossover patients was excluded, the survival rate was 64.9% for HFJV, compared with 47.1% for CV (p less than 0.05). The incidence of chronic lung disease, intraventricular hemorrhage, patent ductus arteriosus, airway obstruction, and new air leak was similar in both groups. We conclude that HFJV, as used in this study, is safe and is more effective than rapid-rate CV in the treatment of newborn infants with pulmonary interstitial emphysema.

Comparative StudyIntellectual outcome in children with maple syrup urine disease.
We report a controlled study of intellectual outcome in 16 children with maple syrup urine disease (MSUD) that compares the outcome of MSUD diagnosed after symptoms became apparent with that of MSUD diagnosed prospectively and in unaffected siblings and parents. The mean IQ (+/- SD) score in the children with classic MSUD was 78 +/- 24; however, there were two discrete groups: one with normal IQ (greater than 84) whose MSUD had been diagnosed at a mean age of 3.5 days and a second group, with IQ below normal, whose MSUD was diagnosed at a mean of 10 days of age. Affected children treated presymptomatically had higher IQ scores than their affected siblings treated when their disease was symptomatic. ⋯ The mean IQ scores of children with variant MSUD, 97 +/- 4, was similar to that of their parents, 103 +/- 6. This study was not longitudinal and thus could not identify subtle developmental learning problems. We conclude that early and meticulous treatment of MSUD can result in intellectually normal children.
