The research is planned as a descriptive, cross-sectional, randomized controlled study to evaluate the effect of using thermal blankets on patients' temperature comfort and shivering levels before open heart surgery.
H1: There is a difference between the effects of using thermal blankets and standard blankets on patients' body temperature in the preoperative period.
H2: The temperature comfort of patients who use thermal blankets in the preoperative period is higher than patients who do not use them.
H3: The temperature perception of patients who use thermal blankets in the preoperative period is higher than patients who do not use them.
H4: Shivering levels of patients who use thermal blankets in the preoperative period are lower than patients who do not use them.
Participants will be asked to cover themselves with a thermal blanket, forced air warming blanket and standard blanket before surgery.
Researchers will compare study 1, study 2 and control groups to evaluate the effect of using thermal blankets on patients' temperature comfort and shivering levels before open heart surgery.
