To explore the relationships between parents' reactions to the pediatric intensive care unit admission of a child and characteristics of the child's illness. ⋯ Parents' reactions to their child's critical illness and admission to the pediatric intensive care unit were not related to characteristics of the child's condition in this small sample. Future research needs are suggested.

Prevalence of, and risk factors for, upper gastrointestinal tract bleeding in critically ill pediatric patients.
To determine the occurrence of, and risk factors for, the development of upper gastrointestinal (GI) tract bleeding in critically ill pediatric patients. ⋯ Overt evidence of upper GI bleeding is not uncommon in critically ill pediatric patients. Certain diagnoses or risk factors may predispose these patients to develop upper GI bleeding.

To determine fluctuation in mixed venous oxygen saturation in critically ill medical patients during a period of rest. ⋯ Knowledge of normal fluctuation enables the care giver to evaluate changes in mixed venous oxygen saturation in response to activities and/or treatments. Additional study of fluctuation in homogenous groups of critically ill patients is warranted.

Comparative StudyDerived oxygen saturations are not clinically useful for the calculation of oxygen consumption.
In critically ill patients, oxygen consumption (VO2) and delivery (DO2) are used to determine optimal haemodynamic management and to grade severity of illness. VO2 may be measured by indirect calorimetry with metabolic gas monitoring systems or derived using the reverse Fick principle. Oxygen saturation (SaO2) may be measured directly by co-oximetry or derived by equations for incorporation into reverse Fick equations. ⋯ When SaO2 was calculated from three logarithmic equations and incorporated into the reverse Fick equations, calculated VO2's were significantly greater (P < 0.001) than those measured by indirect calorimetry. Correlation was poor and wide limits of agreement (-118 to +350 ml/min) were demonstrated. VO2 should ideally be measured by indirect calorimetry in the critically ill, or if reverse Fick is used, SaO2 should be measured by co-oximetry as the use of equations for clinical measurement of SaO2 is clinically suspect.

Randomized Controlled Trial Comparative Study Clinical TrialEffect of acidified enteral feedings on gastric colonization in the critically ill patient.
To evaluate the effect of acidified enteral nutritional formulas (feedings) on gastric colonization and pH in critically ill patients. ⋯ Acidified enteral feedings are effective in eliminating and preventing gastric colonization in critically ill patients. Further investigation is needed to assess its effect on nosocomial infection rates.
