Design outcomes

Primary

MeasureTime frame
Post surgical shivering. Timepoint: Minutes 5 .10 .15. 30. 60. 90. Method of measurement: Based on the checklist for grading the occurrence and severity of shivering according to the reference.

Secondary

MeasureTime frame
Blood pressures. Timepoint: 0?5?10?15?30?45?60?90(min). Method of measurement: Non invasive Sphygmomanometr.;Room temperature. Timepoint: 0?5?10?15?30?45?60?90(min). Method of measurement: E.SUN thermometer.;Core temperature. Timepoint: 0?5?10?15?30?45?60?90(min). Method of measurement: The temperature is measured in the inner ear using a tympanic membrane thermometer, which is considered equivalent to the core temperature. The thermometer used is the GENTLE TEMP 520 model from OMRON.
