forced-air, hypothermia, TUR-P surgery, core temperatures, prewarming, general anaesthesia
Brief summary
36 patients American society of anesthesiology (ASA) physical status I,II and III undergoing general anesthesia for elective transurethral resection of the prostate (TUR-P) surgery will be included in the study. Patients will be randomized into two groups; first group(control group) and second group (forced-air warming). Resistive heating will start when patients are transferred to the operating room table; forced-air warming will start before preoperative 30 minute.
Detailed description
The primary aim of this study was to compare the effect of prewarming on perioperative hypothermia in elderly patients undergoing TURP under general anesthesia. In addition, we aimed to evaluate the effects of prewarming on hemodynamic variables, PACU output time, tremor, patient comfort and satisfaction. The investigators plan to enroll 36 patients in 2 groups. Body temperature will be measured at the core temperature, hemodynamic variables. Shivering will be graded by visual inspection. Thermal discomfort scale, patient satisfaction will be evaluated. The investigators hypothesize will decrease the forced air prewarming incidence of perioperative hypothermia.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Perioperative measurements of core temperature (centigrade ° C) | 2-3 hours | After the operation patients will be admitted to the PACU. Here, body temperature will be assessed and the incidence of hypothermic patients (body temperature \< 36°C)will be measured. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Evaluation of hemodynamic variables (arterial blood pressure) | 2-3 hours | systolic blood pressure (SBP) in mmHg, diastolic blood pressure (DBP) in mmHg, mean arterial pressure (MAP) in mmHg will be measured. |
| Evaluation of hemodynamic variables (heart rate) | 2-3 hours | heart rate (HR) in beats per minute will be measured. |
| Number of patients with postoperative shivering | 2-3 hours | After the operation patients will be admitted to the PACU. Here, postoperative shivering will be measured and graded by visual inspection. |
Other
| Measure | Time frame | Description |
|---|---|---|
| To assess patient satisfaction | 12 hours | patient satisfaction scale (using a Likert scale type (range, 1 to 7) verbally administered questionnaire for patient satisfaction) |
