Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients in group A- they were heated with forced air warmer during preoperative and postoperative period- were managed with administrations following respectively.
Firstly, Patients preparing in the service to go to the operating room were blanketed with the special apron of the device(forced air warmer) and the device was set up to 43 °C. Patients were heated until they were taken to the operating table throughout 30 minutes at least by the researcher. During the warming core body temperature were measured via the zero heat flux thermometer.
Secondly, When the patients were taken to the operating table, heating with a forced air warmer was terminated by the researcher. The patients were warmed from the beginning to the end of the anesthesia with a carbon fiber blanket that was previously activated at 38 °C, and the temperature was monitored via the zero heat flux thermometer.
Finally, during the postoperative period, after coming out of anesthesia, warming with a carbon fiber blanket was terminated and warming with forced air warmer was restarted and gone on until the patient dressed his/her own clothes. Throughout the whole active warming process, preoperatiively and postoperatively, warmer device was turned off when the core temperature of the patient reached to 37.5 °C and it was turned on again when the temperature mentioned before reached below of the 36.5 °C.

Comparator / control treatment
In control group, almost everything was the same of intervention except preoperative and postoperative warming. Whilst the warming was performed by means of a forced air blanket in the intervention group, it was provided via a green sheet heated previously in the control group (this green sheet is usually used with the aim of covering the surgical area and providing a sterile environment to the surgeon).

Efficacy
Statistical methods / analysis
Postoperative shivering incidence was found % 29.83 by Liu et all. And sample size was determined as 35 patients to decrease the insidence to %5 with %80 power and %95 confidence.(Liu et all 2017 in Medicine) That's why we decided to include 35 patients for each group. And we included 70 patients to trial totaly.. We used IBM SPSS Version 21 for statistical analyses of the trial. Student t test was done to determine the statistical significance between variables in the group A and B when the normallity test was normal. On the other hand Mann whitney U test was done when the normallity test was not normal.
