Randomized Controlled Trial Clinical Trial
Effect of lateral positions on tissue oxygenation in the critically ill.
The purpose of this study was to assess the effect of lateral positions on tissue oxygenation in critically ill patients. ⋯ These findings suggest that lateral positioning of critically ill patients who are hypoxemic or have low cardiac output does not further endanger tissue oxygenation. Evaluation of individual patient responses to position changes in the clinical setting is encouraged until further studies using more heterogenous populations can provide more definitive guidance.

Comparative Study
Atypical presentation of acute myocardial infarction in 3 age groups.
The purpose of this study was to compare the clinical manifestations of first-time acute myocardial infarction (AMI) in 3 age groups of men and women who presented to the emergency departments of 3 acute tertiary care hospitals. ⋯ It is essential that nurses and physicians accurately assess patients with AMI, especially patients in the older age groups who may be presenting atypically. It is also important that professional and nonprofessional public health education initiatives include information regarding both typical and atypical presentation of AMI, particularly in the older patient.

The purpose of this study was to test the hypothesis that hospital noise-induced subjective stress would interact with other subjective environmental and personal stress in a relationship with poorer patient sleep. ⋯ Studies using research designs that assess relationships between multiple patient stress variable interactions and sleep or other stress-related outcomes may produce more accurate results than studies on the independent effects of different types of stress.
