Preoperative pressure sore risk was assessed with the Braden Risk Assessment Scale. The patient's room temperature was recorded on the day of surgery before the patient was admitted for the operation. Body temperature was measured before the patient wore surgical gown. Before leaving the room, patient's body was covered with a woolen blanket. The temperature of the operating room was recorded. Body temperature was stabilized under normothermic conditions with a woolen blanket until the operation began. Body temperature was measured before anesthesia was given. Body temperature was measured in the 1st, 2nd and 3rd hour after anesthesia was given. The patient was evaluated with the Braden Risk Assessment Scale on the first, second and third postoperative days.

Preoperative pressure sore risk was assessed with the Braden Risk Assessment Scale. The patient's room temperature was recorded on the day of surgery before the patient was taken to the operation. Body temperature was measured before the patient wore surgical clothes. The temperature of the operating room was recorded. Body temperature was measured before anesthesia was givenBody temperature was measured at the 1st, 2nd and 3rd hour after anesthesia was given. The patient was evaluated with the Braden Risk Assessment Scale on the first, second and third postoperative days.

Woolen blanket: The people in the experimental group were treated with a standard hospital woolen.

The personal information form prepared by the researcher using the literature consisted of seven items in total, questioning age, gender, marital status, educational status, occupational status, income level and previous hospitalization experience.

It is the form that allows to keep track of the temperature of the patient's room, the temperature of the patient's body before putting on the surgical gown, the temperature of the operating room, the body temperature before anesthesia, and the body temperature in the first, second and third hours following anesthesia.

Braden Risk Assessment Scale includes six sub-scales: sensory perception, moisture, activity, mobility, nutrition, friction and shear.

The total score of the scale ranges between 6-23. A total score of 12 or lower shows high risk; 13-14 moderate risk; 15-16 low risk, and 15-18 considered mild risk for people over 75 years old. The scale includes six sub-scales: sensory perception, moisture, activity, mobility, nutrition, friction and shear. The sub-scales of sensory perception, moisture, activity, mobility and nutrition are scored 1-4; the friction-shear sub-scale 1-3, and the total score ranges between 6-23. The risk increases as the total score decreases. 15-18 points are accepted as low risk in people over 75 years old.
