A Comparative Analysis of Ideal Body Weight Methods for Pediatric Mechanical Ventilation.
A universal method for determining ideal body weight (IBW) for the application of appropriate tidal volumes in children on mechanical ventilation is elusive. We sought to compare 3 commonly used IBW methods for subjects between ages 2 and 20 y. ⋯ The majority of the subjects demonstrated a clinically important error between the actual body weight and the IBW. The percent error increased in subjects > 25 kg actual body weight. These data underline the importance of obtaining height measurements and calculated IBW in pediatric patients who are mechanically ventilated.

Observational StudyBenzodiazepines and Development of Delirium in Critically Ill Children: Estimating the Causal Effect.
Benzodiazepine use may be associated with delirium in critically ill children. However, benzodiazepines remain the first-line sedative choice in PICUs. Objectives were to determine the temporal relationship between administration of benzodiazepines and delirium development, control for time-varying covariates such as mechanical ventilation and opiates, and evaluate the association between dosage of benzodiazepines and subsequent delirium. ⋯ Benzodiazepines are an independent and modifiable risk factor for development of delirium in critically ill children, even after carefully controlling for time-dependent covariates, with a dose-response effect. This temporal relationship suggests causality between benzodiazepine exposure and pediatric delirium and supports limiting the use of benzodiazepines in critically ill children.

Respiratory variations in the inferior vena cava diameter (ΔIVCD) have been studied extensively with respect to their value in predicting fluid responsiveness, but the results are conflicting. The aim of this meta-analysis was to explore the value of ΔIVCD for predicting fluid responsiveness in patients with circulatory shock receiving mechanical ventilation. ⋯ The findings of this study suggest that the ΔIVCD performed moderately well in predicting fluid responsiveness in patients with circulatory shock receiving mechanical ventilation.
