Glucose intolerance in critically ill surgical patients: relationship to total parenteral nutrition and severity of illness.
The authors evaluated the relative influence of severity of illness and total parenteral nutrition (TPN) on glucose intolerance in critically ill surgical patients. Records of TPN administration, serum glucose measurements, and the simplified acute physiology score (SAPS) were extracted from the surgical intensive care unit (SICU) and hospital clinical information systems (CIS) for all patients admitted to the SICU from October 1, 1989 through March 31, 1990. Critical hyperglycemia was defined as glucose > 400 mg/dL and critical hypoglycemia as < 40 mg/dL. ⋯ Mean glucose levels rose with increasing SAPS in both TPN and non-TPN patients. When stratified by severity of illness, TPN patients did not have significantly higher glucose levels than non-TPN patients except for the SAPS = 15 category. The authors conclude that the glucose intolerance noted in critically ill TPN patients reflects their underlying severity of illness rather than TPN administration per se.

This article provides an overview of the literature reviewing the stresses and needs of families of critically ill children. These needs and stresses are summarized and organized to provide a framework for the research-based standard of care that is presented for parents of critically ill children.

The impact of specialized training in critical care producing a heightened index of suspicion for the diagnosis of pneumothorax in intensive care unit (ICU) patients was prospectively examined. During a 12-month period, 28 ICU patients were found to have a pneumothorax. ⋯ Six of these nine initially misdiagnosed pneumothoraces (67%) were correctly diagnosed by a physician with specialized training and experience in critical care medicine prior to any clinical deterioration in the condition of the patients. This study suggests that specialized training and experience in the management of critically ill patients can significantly improve upon the diagnosis of pneumothorax in these patients and limit the occurrence of tension pneumothorax in the same patient population.

To evaluate the effectiveness of two methods of meeting the information needs of families of critically ill patients: an open visiting hour policy and a family information booklet. ⋯ Flexible visiting hours and information booklets were two practical methods of meeting the information needs of families. Open visiting hours, as a singular intervention, significantly improved family satisfaction. The effectiveness of the booklet in assisting families to recall discrete pieces of information supports the further development and use of preprinted materials to assist in meeting family information needs.
