Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients were randomly divided into two groups. Group C (control group, n=20): included patients who oral intake stopped 8 hours before operation and Group CH (preoperative carbohydrate group, n=20): patients that were administered oral carbohydrate fluid (12.6 %, 50 kcal per 100 ml fluid) prepared for preoperative period as 800 ml to be administered 8 hours before the operation and as 400 ml 2 hours before the operation.

Outcomes
Primary outcome [1] 287591 0
tympanic temperature
(for tympanic membrane injury was prevented, tympanic temperature measured via infrared thermometer)
Timepoint [1] 287591 0
before anesthesia induction, in 5-minute intervals after the induction of anesthesia, and in 10-minute intervals in PACU,
during one hour in PACU
Primary outcome [2] 287592 0
mean skin temperature [0.3 (Tchest+Tarm) + 0.2 (Tthigh+Tcalf)]
(peripheral temperatures measured via anesthesia machine thermometers)
Timepoint [2] 287592 0
before anesthesia induction, in 5-minute intervals after the induction of anesthesia, and in 10-minute intervals in PACU, during one hour in PACU
Primary outcome [3] 287593 0
mean body temperature [0.64 x Tcentral + 0.36 x Tskin]
(tympanic temperature measured via infrared thermometer, but peripheral temperatures measured via anesthesia machine thermometers)
Timepoint [3] 287593 0
before anesthesia induction, in 5-minute intervals after the induction of anesthesia, and in 10-minute intervals in PACU, during one hour in PACU
Secondary outcome [1] 298484 0
Shivering score (0: no shivering, 1: presence of one or more of such findings as piloerection, peripheral vasoconstriction, and peripheral cyanosis without muscle movement, 2: presence of muscle activity observable in single muscle group, 3: presence of muscle activity in more than one muscle group, 4: presence of significant muscle activity observed in the whole body)
Timepoint [1] 298484 0
before anesthesia induction, in 5-minute intervals after the induction of anesthesia, and in 10-minute intervals in PACU, during one hour in PACU
Secondary outcome [2] 298486 0
vasoconstriction threshold
(Vasoconstriction was estimated with the [Tforearm- Tfingertip] formula of fingertip blood flow and the obtained value '0' demonstrates the vasoconstriction initiated and the value 4 shows severe vasoconstriction. Central temperature at the time of vasoconstriction formation shows us the vasoconstriction threshold)
Timepoint [2] 298486 0
before anesthesia induction, in 5-minute intervals after the induction of anesthesia, and in 10-minute intervals in PACU, during one hour in PACU

Eligibility
Key inclusion criteria
The study included 40 female patients who were to undergo myomectomy-hysterectomy under general anesthesia with ages ranging between 18 and 50 year and that have I-II ASA physical status classification patients were chosen from among the cases to undergo operation between the hours 08:00 am and 13:00 pm.
Minimum age

Can healthy volunteers participate?
No
Key exclusion criteria
Patients that had an inflammatory disease, diabetes mellitus, muscle diseases, hypo-hyperthyroidism, Parkinson disease, Raynaud phenomenon, with body mass index below 20 and above 30, used drug affecting body temperature (beta-blocker, calcium channel blocker, clonidine, steroid, antiepileptic, NSAI, benzodiazepine) and delayed gastric emptying (pregnancy, gastroesophageal reflux, opioid use) were excluded from the study. In addition, patients that will undergo an operation that takes less than 60 minutes or more than 180 minutes were not included in the study. Patients that had alterations in their hemodynamic parameters more than 30%, patients that required the use of vasopressor or vasodilator, and patients needed blood transfusion were excluded from the study.
