Observational StudyHemodynamic Impact of Oxygen Desaturation During Tracheal Intubation Among Critically Ill Children With Cyanotic and Noncyanotic Heart Disease.
To determine a level of oxygen desaturation from baseline that is associated with increased risk of tracheal intubation associated events in children with cyanotic and noncyanotic heart disease. ⋯ Oxygen desaturation was more commonly observed during tracheal intubation in children with cyanotic versus noncyanotic heart disease. However, hemodynamic tracheal intubation associated event rates were similar. In both groups, oxygen desaturation greater than or equal to 30% was significantly associated with increased occurrence of hemodynamic tracheal intubation associated events.

Accuracy of Reported Tidal Volume During Neonatal Ventilation With Airway Leak: A Lung Model Study.
To determine the accuracy of tidal volume reported by neonatal ventilators, with and without leak compensation, in invasive and noninvasive ventilation modes in the presence of airway leak; and, to determine what factors have a significant effect on the accuracy of tidal volume reported by ventilators with leak compensation in the presence of airway leak. We hypothesized that ventilators with a leak compensation function that includes estimation of tidal volume could accurately report tidal volume in the presence of airway leak, but that the accuracy of reported tidal volume may be affected by variables such as the identity of the ventilator, lung mechanics, leak size, positive end-expiratory pressure level, and body size. ⋯ Reported tidal volume is affected by the presence of airway leak, but in many ventilators a leak compensation algorithm that includes estimation of tidal volume can correct for the discrepancy between actual and reported tidal volume. However, even in ventilators with leak compensation, choice of ventilator and lung mechanics in invasive ventilation modes have a significant effect on error of reported tidal volume.

Early Heart Rate Variability and Electroencephalographic Abnormalities in Acutely Brain-Injured Children Who Progress to Brain Death.
Heart rate variability is controlled by the autonomic nervous system. After brain death, this autonomic control stops, and heart rate variability is significantly decreased. However, it is unknown if early changes in heart rate variability are predictive of progression to brain death. We hypothesized that in brain-injured children, lower heart rate variability is an early indicator of autonomic system failure, and it predicts progression to brain death. We additionally explored the association between heart rate variability and markers of brain dysfunction such as electroencephalogram and neurologic examination between brain-injured children who progressed to brain death and those who survived. ⋯ These results support the concept of autonomic system failure as an early indicator of impending brain death in brain-injured children. Furthermore, decreased heart rate variability is associated with markers of CNS dysfunction such as electroencephalogram abnormalities.

Observational StudyDerivation and Validation of an Objective Effort of Breathing Score in Critically Ill Children.
To derive and validate a score that correlates with an objective measurement of a child's effort of breathing. ⋯ A scoring system was derived and validated, performed acceptably to predict increased effort of breathing or need for advanced respiratory support and may function best when used by a team.

A National Survey on Interhospital Transport of Children in Cardiac Arrest.
To describe the U.S. experience with interhospital transport of children in cardiac arrest undergoing cardiopulmonary resuscitation. ⋯ A minority of U.S. teams perform interhospital transport of children in cardiac arrest undergoing cardiopulmonary resuscitation. Eligibility criteria, transport logistics, and patient outcomes are heterogeneous. Importantly, there is a paucity of established safety protocols for the staff performing cardiopulmonary resuscitation in transport.
