The Effect of Using a Thermal Blanket on Temperature and Shivering Levels

The Effect of Using Thermal Blankets on Patients Temperature Comfort and ShiveringLevels Before Open Heart Surgery

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.

Randomization method will be used to determine the groups. Randomization of the patients was done using the 'Random Allocation Software 1.0' program and the patients were divided into 3 groups: study group 1, study group 2 and control group.

The patients will be visited by the researcher in their rooms on the afternoon before the day of surgery, and then the first part of the data collection form will be filled out in approximately 10 minutes by face-to-face interview. Then, thermal blankets and forced-air warming blankets will be introduced, information will be given about their use according to the stages of the study, and they will be informed that they will meet again the next day in the morning.

Study group patients Patients in this group will be visited in their rooms by the researcher on the morning of surgery. Patients will be given a thermal blanket or forced-air warming blanket to use during the transfer process. Patients will be asked to notify the researcher if they stop using the blanket.A data collection form was used to evaluate the patients' physiological parameters, Temperature Comfort Scale, Thermal Comfort Scale were used to evaluate the comfort levels, and the Shivering Assessment Scale was used to evaluate the shivering level.

Controll group patients Patients will be informed that they will be visited on the day of surgery and that they will be given a standard blanket to use during the transfer phases. No other intervention will be made. A data collection form was used to evaluate the patients' physiological parameters, Temperature Comfort Scale, Thermal Comfort Scale were used to evaluate the comfort levels, and the Shivering Assessment Scale was used to evaluate the shivering level.
