Maternal Core Body Temperature
Time frame: preoperative/beginning of surgery, postoperative/end of surgery (4 hours after anesthesia)
Number of Women With Hypothermia
Hypothermia is indicated as core temperature \< 36 °C
Time frame: preoperative/beginning of surgery ,postoperative/end of surgery (4 hours after anesthesia)
Neonate Status as Determined by Appearance, Pulse, Grimace, Activity, and Respiration (APGAR) Score
The Apgar score is determined by evaluating the newborn baby on each of five criteria (appearance, pulse, grimace, activity, respiration) on a scale from zero to two, then summing the five values obtained. The total score ranges from zero to 10. A higher score indicates a better outcome.
Time frame: 1 minutes after birth, 5 minutes after birth
Umbilical Artery pH
Time frame: 10 minutes after birth
Maternal Coagulopathy
Time frame: end of surgery (4 hours after anesthesia)
Degree of Shivering (Severity)
Degree of shivering is measured from 0(no shivering)-3(total body shivering), a higher score indicates greater shivering.
Time frame: on arrival to Post anesthesia Care Unit (PACU) [about 4 hours after anesthesia]
Number of Patients That Need Meperidine
Time frame: on arrival to PACU [about 4 hours after anesthesia]
Number of Patients That Need Meperidine
Time frame: after 30 minutes in PACU

Time frame: after administration of meperidine, if it applies (about 30 minutes in PACU)
Maternal Thermal Comfort
Maternal thermal comfort has a total score range from 0 to 10,a higher number indicating more thermal comfort
Time frame: end of surgery (4 hours after anesthesia)
