Outcome of intensive care of the "oldest-old" critically ill patients.
To determine the short-term and long-term outcome of critically ill "oldest-old" (greater than or equal to 85 yrs) patients. ⋯ These findings suggest that age alone may be an inappropriate criterion for allocation of ICU resources.

Comparative Study
Prospective comparison of clinical judgment and APACHE II score in predicting the outcome in critically ill surgical patients.
Prospective identification of patients who will not survive has been proposed as a means of limiting utilization of medical resources including critical care. This study prospectively compared prediction of outcome for surgical ICU patients by clinical assessment and the APACHE II score. Five hundred seventy-eight patients were assessed within 24 hours of admission by the ICU attending physician and predicted to live or die. ⋯ Over 40% of patients predicted to die by both methods actually survived. This study demonstrates that clinical assessment is superior to APACHE II in predicting outcome in this group of surgical patients, although the difference is small. In addition, this study suggests that neither clinical assessment nor the APACHE II score, when obtained within 24 hours of admission, is very reliable at predicting which surgical ICU patients will die.

ReviewSelective decontamination of the digestive tract in the intensive care unit: current status and future prospects.
To evaluate the available data on selective decontamination of the digestive tract. This therapy aims to prevent infection in critically ill patients admitted to ICUs. Microbial carriage in the oropharynx, stomach, and gut; infection; mortality rate; and antibiotic resistance are the outcome events that are being reviewed. ⋯ There is a general consensus about the efficacy of selective decontamination in diminishing microbial carriage and acquired infection rates, although conclusions about benefits related to mortality rates vary. Differences in mortality rate are found in the selective decontamination studies of patients with curable diseases, including multitrauma and cardiovascular patients. More data on resistance, collected over a longer period of time, are needed. Practical problems of blinding and the major ecological effect of selective decontamination may explain the lack of a randomized, placebo-controlled, double-blind trial.

Randomized Controlled Trial Clinical TrialGastric colonization and pneumonia in intubated critically ill patients receiving stress ulcer prophylaxis: a randomized, controlled trial.
To study the effects of pharmacologically increasing gastric pH on gastric colonization and the development of pneumonia in intubated critically ill patients. ⋯ Pharmacologically increasing gastric pH increases the risk for developing pneumonia in intubated critically ill patients. The pneumonia occurs earlier than in untreated control patients.

ReviewEndocrine responses to the stress of critical illness.
The physiologic and psychologic stress of critical illness produces systemic endocrine responses that affect the body's ability to achieve and maintain homeostasis. Regardless of the nature of the stress or illness, specific hormonal changes occur in thyroid, adrenal, and posterior pituitary activity. This article describes the physiologic and pathophysiologic basis underlying endocrine responses to the stress of critical illness. The critical care nurse is challenged by the complexity of this patient and needs to be familiar with the endocrine responses to critical illness for assessment and clinical interventions to be meaningful.
