Data regarding pediatric in-hospital cardiopulmonary resuscitation (CPR) have been limited because of retrospective study designs, small sample sizes, and inconsistent definitions of cardiac arrest and CPR. The purpose of this study was to prospectively describe and evaluate pediatric in-hospital CPR with the international consensus-derived epidemiologic definitions from the Utstein guidelines. ⋯ During this study, CPR was uncommon but not rare. Respiratory failure was the most common precipitating cause, followed by shock. Preexisting chronic diseases were prevalent among these children. Asystole was the most common initial cardiac rhythm, and bradycardia with pulses and poor perfusion was the second most common. Ventricular fibrillation was rare, but children with acute cardiac diseases, such as cardiac surgery and acute cardiomyopathies, were not admitted to this children's hospital. CPR was effective: nearly two thirds of these children were initially successfully resuscitated, and one third were alive at 24 hours compared with imminent death without CPR and advanced life support. Nevertheless, survival progressively decreased over time, generally as a result of the underlying disease process. One-year survival was 15%. Importantly, most of these survivors had no demonstrable change in gross neurologic function from their pre-CPR status.

To investigate underascertainment of unexpected infant deaths at the national level as a result of probable classification as attributable to unknown cause. ⋯ Risk profiles indicate that deaths of unknown cause are likely to represent a mixture of unexpected deaths. The process for determination of cause of unexpected death affects national underascertainment of SIDS and injury deaths. Better coordination among child fatality review teams and local, state, and national officials should reduce underascertainment and improve documentation of circumstances surrounding deaths for prevention efforts.

Activated CD8 as well as CD4 T cells contribute to the production of asthma-relevant cytokines in both atopic and nonatopic childhood asthma. ⋯ The data are consistent with the hypothesis that both activated CD4 and CD8 T cells are associated with child asthma, and that CD4 T cells make a greater contribution to IL-4 and IL-5 synthesis. Increased dosages of inhaled glucocorticoid resulted in clinical improvement in the asthmatics along with reduced T-cell activation and cytokine mRNA expression, suggesting a possible causal association.

Guidelines for risk reduction during procedural sedation from the American Academy of Pediatrics (AAP) and the American Society of Anesthesiologists (ASA) rely on expert opinion and consensus. In this article, we tested the hypothesis that application of an AAP/ASA-structured model would reduce the risk of sedation-related adverse events. ⋯ Presedation assessment reduces complications of DS. Repeated assessment of sedation score reduces the risk of inadvertent DS. The data provide direct evidence that AAP/ASA guidelines can reduce the risk of pediatric procedural sedation.

Treatment of dehydrating gastroenteritis, a major cause of morbidity in children, remains controversial. Practice parameters issued by the American Academy of Pediatrics (AAP) recommend oral rehydration therapy (ORT) as the preferred treatment for losses from both mild and moderate dehydration. The objective of this study was to test the hypothesis that awareness of the AAP practice parameters would be associated with a higher rate of use of ORT among emergency physicians. ⋯ This is the first national study to establish a relationship between awareness of the AAP practice parameters and physician practices in the treatment of dehydration. Emergency medicine physicians who were very familiar with the AAP parameters were significantly more likely to use ORT. These findings may have important implications for future efforts directed at increasing the rate of ORT use and for the evaluation of practice parameters in general.
