The aim of this study was to evaluate the effect of heating the intensive care room in the early postoperative period on patient outcomes.
Hypothermia is defined as a drop in body temperature below 35°C, and patients are at high risk during the perioperative period.Unintentional hypothermia can begin before anesthesia and continue for up to the first 24 hours postoperatively.Its incidence varies between 50% and 90% depending on the patient's medical condition, the nature of the surgery, and operating room conditions.Hypothermia leads to complications such as arrhythmia, hypertension, angina, coagulopathy, increased oxygen demand, nausea, vomiting, and delayed wound healing.Additionally, adverse effects such as shivering, changes in cognitive function, decreased patient comfort, and prolonged hospital stay are also observed.The development of hypothermia is influenced by anesthesia-related thermoregulation impairment, a cold operating room environment, and prolonged operations.Patients report experiencing intense chills and shivering, especially in the postoperative period.
This increases anxiety and negatively impacts patient satisfaction and comfort. Guidelines recommend the use of passive and active warming methods to prevent unintended hypothermia.However, no studies have been found in the literature examining the effect of heating the patient room in the postoperative period.In this regard, our study was designed to evaluate the effect of heating the intensive care room in the early postoperative period on patient outcomes and to contribute to the literature.

Exclusion Criteria:
In the preoperative period, patients with a body temperature of 36°C-37°C one hour before surgery will be included in the sample. Postoperatively, upon arrival from the operating room to the intensive care unit, which has a humidity range of 55%-65% and a temperature range of 22°C-25°C, will be safely transferred to a single-bed room, monitored, and wiped down. After ensuring personal hygiene, the patient will be covered with a 160x220cm cotton quilt. The heating device hose will be placed inside the bed from the side of the bed. The electric heater will be operated at 38°C (Medium) for 120 minutes, 15 cm from the patient's body. Routine treatment and care will then be administered. Vital signs, shivering level, and temperature perception will be recorded on the patient's follow-up form at 0, 15, 30, 45, 60, 90, and 120 minutes postoperatively.

In the postoperative period, the intensive care room, which has a routine humidity range of 55%-65% and a temperature of 22°C to 25°C, will be heated to the upper limit of the intensive care room temperature range, 27°C, with an electric heater half an hour before the operation. After ensuring personal hygiene, the patient will be safely transferred to the bed in the single room, monitored, and wiped down. After ensuring personal hygiene, the patient will be covered with a 160x220cm cotton quilt. The heating device hose will be placed inside the bed from the edge of the bed. The electric heater will be operated at 38°C (Medium Level) for 120 minutes, 15cm from the patient's body. Routine treatment and maintenance will be administered. Then, the vital signs, pain, shivering level, and temperature perception will be recorded in the patient follow-up form a

The Thermal Comfort Scale (TKS)
The Thermal Comfort Scale (TKS) is a Likert-type scale developed by Wagner and colleagues in 2006. Although it was developed to assess the thermal comfort perception of preoperative patients, the authors state that it is also suitable for evaluating conscious postoperative patients. The scale assesses the patient's thermal comfort perception based on self-report. The scale consists of 13 items, each scored from 1 to 6. A higher score indicates a higher thermal comfort perception.
Time frame: 6 months
Temperature Comfort Perception Scale (TPS)
The Temperature Comfort Perception Scale is a visual analog scale developed by Wagner and colleagues to objectively assess patients' perception of temperature comfort. It is scored based on patient self-reporting from 0 (extremely cold) to 10 (extremely hot), with a score of 5 representing optimal temperature comfort.
Time frame: 6 months
Numerical Pain Assessment Scale (SAS)
This study planned to use a 10-point pain scale, with 0 representing no pain and 10 representing the most unbearable pain. In the study, patients will be asked to select the number that best describes their pain intensity.
Time frame: 6 months
Tremor Level Assessment Scale (TRS)
Tremor Level Assessment Scale (TRS) This form, used to assess patients' tremor levels, was developed based on literature. The form was developed using the studies of Badjaita et al. (2008) and May et al. (2011), and was based on criteria for determining the level of tremor based on observation. Tremor level will be assessed based on observation as follows: 0 (absent), 1 (mild; tremor localized only to the neck and/or thorax), 2 (moderate; tremor in the neck, thorax, and upper extremities), and 3 (severe; tremor in the trunk, upper, and lower extremities).
Time frame: 6 months
Patient Monitoring Form (PMP)
Patient Monitoring Form (PMP) This form was developed by researchers based on a literature review to monitor the body temperature, blood pressure, pulse, respiration, pain, oxygen saturation, shivering levels, thermal comfort perception, and thermal comfort levels of patients in the intervention and control groups.

Started Apr 2025 (actual). Primary completion is estimated for Oct 2025, 6 months after the start.
Of 132 non-industry interventional studies with no phase under Hypothermia, half reached primary completion within 16 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 36. This study's planned 6 months is below that.
Counting every sponsor, half of 135 studies reached it within 16 months; a quarter within 6 and three quarters within 36.
