Randomized Controlled Trial Clinical Trial
Effects of relaxing music on cardiac autonomic balance and anxiety after acute myocardial infarction.
Acute myocardial infarction places additional demands on an already compromised myocardium. Relaxing music can induce a relaxation response, thereby reversing the deleterious effects of the stress response. ⋯ Patients recovering from acute myocardial infarction may benefit from music therapy in a quiet, restful environment.

Randomized Controlled Trial Clinical Trial
The effect of earplugs on sleep measures during exposure to simulated intensive care unit noise.
Sleep deprivation may contribute to impaired immune function, ventilatory compromise, disrupted thermoregulation, and delirium. Noise levels in intensive care units may be related to disturbed sleep patterns, but noise reduction has not been tested in this setting. ⋯ The results provide a reasonable basis for testing the effects of earplugs on the sleep of critically ill subjects.
