Prospective assessment of guidelines for determining appropriate depth of endotracheal tube placement in children.
To determine whether multiplying the internal diameter of the endotracheal tube (ETT) by 3 (3x ETT size) is a reliable method for determining correct depth of oral ETT placement in the pediatric population. ⋯ The commonly used formula of 3x tube size for ETT depth in children results in 15-25% malpositioned tubes. Practitioners can improve the reliability of this formula by utilizing the recommended ETT size as suggested by the Broselow tape. A more reliable method is necessary to avoid ETT malposition.

Frequency of intracranial pressure monitoring in infants and young toddlers with traumatic brain injury.
To examine the use of intracranial pressure monitors and treatments for elevated intracranial pressure in brain-injured children of <2 yrs of age and compare them with the recently published management guidelines. ⋯ Brain injury in young children may lead to many years of lost quality of life. The utility of monitoring intracranial pressure in infants has not been well established, which may be a reason for its low use. As most infants with traumatic brain injury survive, high-quality studies with neurodevelopmental measures as the primary outcome are urgently needed to document best practice in this subpopulation.

Comparative StudyParents' reactions at 24-48 hrs after a preschool child's head injury.
Our objectives were, first, to compare mothers' and fathers' early reactions (stressors, concerns) to the preschool child's head injury, their perceptions of the child's injury severity, and their social support and mental health; second, to compare families with a child in the pediatric intensive care unit (PICU) vs. general care unit (GCU) on these variables; and third, to describe the relationships between parents' early reactions and perceived and objective injury severity, their social support, and mental health. ⋯ Although mother-father couples rated their child's injury severity similarly, mothers experienced more stress than fathers. Social support decreased the stress for mothers but not for fathers. The experience of pediatric head trauma was more stressful for mothers of children in the PICU than mothers of children in the GCU.

Intestinal mucosal ischemia can occur during and after cardiac surgery. Severe decreases in mucosal perfusion may be a causative factor for postoperative mortality or complications such as necrotizing enterocolitis. Mesenteric perfusion is challenged preoperatively due to an imbalance between the systemic and pulmonary circulations and challenged intraoperatively due to hypothermic circulatory arrest. We have investigated gut permeability in seven patients undergoing stage 1 of the Norwood procedure, applying the dual sugar permeability test with L-rhamnose and lactulose. ⋯ Gut permeability as assessed by the dual sugar permeability test is abnormal in patients with hypoplastic left heart syndrome before and after surgery. Lactulose/rhamnose ratios 46 times the normal value reflect a highly permeable small intestine. This may be a sign of a low output state and may help to identify patients at risk of developing necrotizing enterocolitis.

To assess what independent influence, if any, weekend or evening admission to a pediatric intensive care unit (PICU) staffed 24 hrs/day, 7 days/wk by in-house, board-certified pediatric intensivists might have on mortality. ⋯ Using multivariate logistic regression to control for important clinical differences, neither weekend admission, weekend discharge/death, nor evening admission had a significant independent effect on mortality risk in the entire sample or for the emergency patient subset. Our findings are consistent with previous work demonstrating the benefit of intensive care units staffed 24 hrs/day, 7-days/wk by in-house, board-certified intensivists.
