Randomized Controlled Trial Clinical Trial
Coping with unplanned childhood hospitalization: effects of informational interventions on mothers and children.
Two types of information, separately and in combination, were evaluated for their effects on the process and outcomes of maternal and child coping with unplanned childhood hospitalization. One hundred eight mothers of hospitalized children, 2 to 5 years old, were randomly assigned to one of four study groups. Child behavioral information and parental role information had positive effects on maternal state anxiety as well as on parental support and participation in their children's care during hospitalization. Ten to 14 days following hospitalization, positive main effects were shown for child behavioral and parental role information on mothers' state anxiety levels and for child behavioral information on children's negative behaviors.

Comparative Study
Multidimensional predictors of success or failure with early weaning from mechanical ventilation after cardiac surgery.
The purpose of this study was to determine the contributions of pulmonary mechanics, gas exchange, and hemodynamic function to prediction of success or failure with early weaning from mechanical ventilation after cardiac surgery. More than 40 physiologic measurements were determined on 162 patients at two time points in the early postoperative period: during full-support mechanical ventilation and during a trial of spontaneous ventilation. Discriminant analysis was used to analyze the differences between the success group (n = 134) and the failure group (n = 28) and to predict group membership of individual cases. ⋯ The discriminant function contained variables from all three dimensions of weaning criteria, with dimensions of hemodynamic function and pulmonary mechanics having greater import. The predictor set had a sensitivity of .98, specificity of .71, positive predictive value of .94, and negative predictive value of .87. Routine bedside measurements had a predictive performance equal or superior to variables previously studied.
