Design outcomes

Primary

Measure	Time frame
Shivering. Timepoint: During cesarean section until the end of the patient's recovery time. Method of measurement: Specific shivering scale for neuraxial anesthesia as defined by Grassley and Mahagan 0: No chills, 1: No muscle activity is visible but there is flexibility or contraction of peripheral arteries or both 2: Muscle activity in only one muscle group 3: Moderate muscle activity in more than one muscle group but no overall vibration 4: Activity Intense muscles that involve the whole body.	—

Secondary

Measure	Time frame
Central body temperature. Timepoint: Every 5 minutes from the beginning of cesarean section for the first 20 minutes, then every 10 minutes to 30 minutes, and finally every 15 minutes until the end of the recovery time. Method of measurement: OMRON brand tympanic thermometer.;Sensory block surface. Timepoint: Every 5 minutes from the start of cesarean section for the first 20 minutes and then every 10 minutes to 30 minutes. Method of measurement: PINPRICK test.;Hemodynamic variables. Timepoint: Every 5 minutes from the beginning of cesarean section for the first 20 minutes, then every 10 minutes to 30 minutes, and finally every 15 minutes until the end of the recovery time. Method of measurement: Blood pressure and heart rate monitor.;Nausea and vomiting. Timepoint: 5 minutes after the start of cesarean section until the end of the recovery time. Method of measurement: Sick symptoms.;Need an analgesic supplement. Timepoint: 5 minutes after the start of cesarean section until the end of the recovery time. Method of measurement: Request the patient to receive an analgesic supplement according to the symptoms.	—
