Behavioral responses of family members during critical illness.
This articles describes the behavioral responses of adult family members to critical illness and how these responses change over the course of the hospitalization. A convenience sample of 52 family members of patients in intensive units completed the Iowa ICU Family Scale, a self-report tool measuring sleep, eating, activity, family role, and support behaviors. ⋯ Stress was highest at the time of the ICU admission, began to plateau at Day 6, and then dropped considerably by Day 28. These findings suggest that crisis intervention is important during the early phase of caring for critically ill patients and their family members.

To determine the individual contributions of variables in the Fick equation to cardiac output, we simultaneously measured oxygen uptake (VO2), carbon dioxide production (VCO2), venous oxygen saturation (SvO2) and thermodilution cardiac output (Qth) in 28 medical and surgical ICU patients. Patients were intubated and ventilated with the intermittent mandatory ventilation mode. VO2 and VCO2 (averaged over 3 min) were obtained from a metabolic cart. ⋯ None of the above oximetry relationships were substantially altered by use of COoximetry venous oxygen saturations. We conclude that Qth cannot be predicted well solely from VO2, VCO2, or SvO2 nor can changes in Qth be predicted well solely from changes in VO2, VCO2, or SvO2. Of the metabolic variables, changes in VCO2 best predicted changes in Qth.

During the past several decades, the transport of critically ill patients to and between hospitals has gradually improved. The major indications that necessitate emergency transport for adult patients are trauma and acute cardiac disease, and the establishment of transport teams trained in the care of these conditions has improved the outcome of adult patients. ⋯ Such a program emphasizes stabilization of the child's condition at the local hospital, followed by transport to a pediatric intensive-care facility by a specially trained pediatric transport team. In this review, we present an overview of the principles and operating procedures of such pediatric transport teams.

Comparative StudyPredictability of creatinine clearance estimates in critically ill patients.
a) To evaluate the predictive ability of different creatinine clearance methods as compared with the criterion standard, inulin clearance; and b) to determine which of the predictive methods yields the most accurate estimation of creatinine clearance. ⋯ The utilization of the Cockcroft-Gault equation as used clinically (the lower of ideal or total body weight and the higher of actual serum creatinine or corrected serum creatinine concentration to 1 mg/dL [85 mumol/L]) results in more accurate predictions of glomerular filtration rate in the medical, critically ill patient than urine creatinine clearance measures. If creatinine clearance measures are used, the 30-min collection provided results not different from those results obtained with 24-hr urinary collections.
