Observational StudyCharacterization of the Glucocorticoid Receptor in Children Undergoing Cardiac Surgery.
Postoperative administration of corticosteroids is common practice for managing catecholamine refractory low cardiac output syndrome. Since corticosteroid activity is dependent on the glucocorticoid receptor, we sought to characterize glucocorticoid receptor levels in children undergoing cardiac surgery and examined the association between glucocorticoid receptor levels and cardiovascular dysfunction. ⋯ Increasing glucocorticoid receptor levels in peripheral WBCs of children undergoing cardiac surgery are associated with a longer time to being inotrope free. Cortisol levels minimally increased during the study duration. These results suggest that exposure to high-dose perioperative corticosteroids may suppress the hypothalamic-pituitary-adrenal axis leading to increase in glucocorticoid receptor levels in response to a low cortisol environment. Further studies are required to better delineate the interplay between glucocorticoid receptor levels, cortisol levels, corticosteroid exposure, and postoperative inotropic requirements.

Observational StudyCorrected QT Interval Prolongation in Hospitalized Pediatric Patients Receiving Methadone.
Methadone is often used in pediatric patients to prevent or treat opioid withdrawal after prolonged sedation. Prolonged corrected QT interval is an important adverse effect of methadone because it can progress to torsades de pointes, a potentially fatal dysrhythmia. The prevalence of corrected QT interval prolongation and contributing risk factors are not well defined in hospitalized pediatric patients receiving methadone. The study purpose was to identify the frequency and risk factors of corrected QT interval prolongation in hospitalized pediatric patients receiving methadone. ⋯ In hospitalized pediatric patients receiving methadone, corrected QT interval prolongation was common, but no episodes of torsades de pointes were documented. Risk factors that have been identified in adults were not associated with prolongation in our study population.

An Ethical Claim for Providing Medical Recommendations in Pediatric Intensive Care.
The Declaration of Geneva was recently revised to emphasize patient autonomy and the importance of clinicians sharing medical knowledge. This reflects the welcome evolution of the doctor-patient relationship from one of paternalism to more informed, shared decision-making. Unfortunately, there is an increasing trend for clinicians to avoid making recommendations, instead providing a "menu" of care options from which patients and families must choose. ⋯ We outline how a failure to provide clinical recommendations represents inadequate shared decision-making and erodes the doctor-patient relationship, leading to suboptimal care, paradoxically decreasing respect for autonomy. We describe an approach through which doctors can avoid paternalism without placing an undue burden of decision-making on families. We assert that patients' interests are best served by clinicians taking an active, relational role in shared decision-making, including exploration of values and giving explicit medical recommendations for care.

Admission Hyperoxia Is a Risk Factor for Mortality in Pediatric Intensive Care.
To determine whether the association between hyperoxia and increased risk-adjusted mortality in adult intensive care patients is also observed in a pediatric intensive care population. ⋯ In this single-center study, hyperoxia at admission to the PICU was highly correlated with increased risk-adjusted mortality. Further investigation of these observations in a large multicenter cohort is warranted.

Fosphenytoin Population Pharmacokinetics in the Acutely Ill Pediatric Population.
The purpose of this study is to describe the pharmacokinetics of phenytoin in pediatric patients receiving fosphenytoin. ⋯ A loading dose of 20 mg/kg followed by 6 mg/kg/dose every 8 hours based on fat-free mass is a reasonable empiric strategy for attainment and maintenance of therapeutic trough concentrations. Concomitant phenobarbital use may increase clearance of phenytoin and fosphenytoin dose reductions should occur in patients with reduced kidney function.
