Randomized Controlled Trial
Effects of Nurse-Led Intervention on Patients' Anxiety and Sleep Before Coronary Artery Bypass Grafting.
The aim of this study to examine the effects of supportive-educational nurse-led intervention on the patients' anxiety and sleep before the coronary artery bypass grafting. The current clinical trial recruited 160 patients (N = 160) waiting for the coronary artery bypass grafting by random block sampling and divided them into two 80-people experimental and control groups. Spielberger's State Anxiety Inventory was completed on the first day. ⋯ The comparison of the mean quality of sleep the night before the surgery for both groups showed that sleep in the control group compared with sleep in the experimental group had a lower quality, and statistically, it was significant (P < .001). Results showed that nonpharmacological and supportive interventions can reduce patients' anxiety and sleep disturbance before the coronary artery bypass grafting. According to the results, nonpharmacological therapies should be placed at the top of nurses' tasks.

Randomized Controlled Trial Clinical Trial
The effect of head covering on rewarming and shivering in cardiac surgical patients.
In hypothermic postoperative cardiac surgical patients, heat loss from the head may interfere with rewarming and cause shivering. This study investigated the effect of head covering on rewarming rate and shivering during post-operative rewarming. The sample included 19 experimental and 21 control subjects. ⋯ Shiverers were slightly colder (mean, 36.13 degrees C; t = 1.768; P = .085) on admission to the cardiac surgical intensive care unit and had significantly greater heat gain (t = -2.091, P = .043) than nonshiverers. Conclusions about the effect of head covering on shivering could not be made because of small sample size. Failure to demonstrate a significant difference in rewarming rate is due to the effects of mildly hypothermic admission UBTs on the mathematical calculation of rewarming rate and on the small sample size.
