Factors associated with brain herniation in the treatment of diabetic ketoacidosis.
To determine factors contributing to life-threatening brain herniation in patients treated for severe diabetic ketoacidosis, we analyzed history, laboratory data, rate and composition of fluid and insulin administration, and time to onset of brain herniation in nine new cases and 33 prior reports. The overall rate of fluid administration was inversely correlated with the time of onset of herniation (r = -0.32, p = 0.04). ⋯ During treatment, "calculated" serum sodium concentrations fell significantly and were less than 130 mEq/L in 33% of cases at the time of herniation. These data indicate that excessive secretion of vasopressin may exacerbate the brain edema, and that limitation of the rate of fluid administration may be prudent.

Randomized Controlled Trial Clinical TrialNeed for endotracheal intubation and suction in meconium-stained neonates.
In a prospective study, we determined whether routine immediate tracheal aspiration at birth is necessary in meconium-stained but otherwise normal infants delivered vaginally and having a 1-minute Apgar score greater than 8. A total of 572 newborn infants who met these criteria were randomly allocated to one of two groups. ⋯ There was no mortality among infants in the study, but morbidity, mainly pulmonary and laryngeal disorders, occurred in six of 308 group I infants and in none of the group II infants (P less than 0.025). Immediate tracheal suction is not a harmless intervention, and should be considered superfluous in a vigorous term neonate born with meconium-stained amniotic fluid.

Axial movement of the right hemidiaphragm during tidal breathing was recorded using real-time ultrasonography in 46 healthy term infants. Displacement was 2.6 +/- 0.1, 3.6 +/- 0.2, and 4.5 +/- 0.2 mm (mean +/- SEM) for the anterior, middle, and posterior thirds, respectively. Diaphragmatic movement was significantly greater in the middle and posterior segments than in the anterior segment (P less than 0.0001). ⋯ Diaphragmatic movement was also assessed in nine infants who required mechanical ventilation and pharmacologic paralysis because of respiratory disease. In these infants, axial movement of the right hemidiaphragm was less in the middle and posterior thirds (P less than 0.05 and P less than 0.01, respectively) than in spontaneously breathing infants, and posterior movement was not predominant. Normative data for axial diaphragmatic movement may be of clinical value in the assessment of defects of the diaphragm, rib cage, or abdomen in newborn infants and may allow further understanding of the direct effects of therapeutic interventions on the respiratory system in infancy.

ReviewAdult respiratory distress syndrome in pediatric patients. II. Management.
Adult respiratory distress syndrome, a clinical syndrome of respiratory failure that follows many kinds of insults, often in patients with no previous pulmonary disease, occurs in pediatric patients. This group of disorders has a typical clinical, pathologic, and pathophysiologic course, the hallmark of which is injury to the alveolar-capillary membrane with increased permeability of the pulmonary vasculature and pulmonary edema. Resolution may occur at any stage, but most patients die and many develop chronic lung disease requiring respiratory support for weeks or months. ⋯ Efforts to treat ARDS after it is clinically apparent have been disappointing. The pathogenic mechanisms that lead to ARDS are probably well advanced by the time the syndrome is diagnosed on the basis of the usual clinical signs. Therefore an emphasis on understanding the mechanisms of lung injury so that specific markers can be used to predict which patients will develop ARDS, allowing intervention in the early stages of the process, may prove rewarding.

Patient, parent, and physician perspectives on pediatric oncology rounds.
To provide data to guide physicians regarding the extent to which pediatric patients and their families should be involved in decision-making discussions by their health care teams, we compared the standard rounding procedure in a pediatric oncology unit (rounds conducted out of earshot) with bedside rounds in which management was discussed in front of patients and parents. Type of rounds was alternated in 2-week blocks for 4 months. The impact of the two types of rounds of 35 parents and children was studied. ⋯ Older children, compared with younger children, more strongly disliked standard rounds; this appeared to be related to feelings of exclusion. The two types of rounds differed in their effectiveness in providing specific types of education to residents. The findings suggest that bedside rounds have a positive impact on parents' attitudes toward physicians, that they do not dilute the child's sense of relationship with the primary attending physician, and that they contribute to certain aspects of resident education.
