Design outcomes

Primary

MeasureTime frame
Core Body Temperature Every 10 minutes intraoperatively, and at 0, 10, 20, 30 minutes, 6, 12, and 24 hours postoperatively Esophageal temperature,Postoperative nausea and vomiting At 0, 10, 20, and 30 minutes in the post-anesthesia care unit, and at 6, 12, and 24 hours postoperatively 4-point ordinal scoring system (1: no nausea or vomiting, 2: nausea, 3: retching, 4: vomiting)

Secondary

MeasureTime frame
Hemodynamic parameters Every 10 minutes intraoperatively, and at 0, 10, 20, 30 minutes, 6, 12, and 24 hours postoperatively Heart rate, mean arterial pressure, and peripheral oxygen saturation (SpO2) recorded by standard patient monitor
