Outcomes

Primary Outcome Measures

Change in maternal core body temperature
Number of women with hypothermia
Hypothermia is indicated as core temperature < 36 °C
Neonate status as determined by Appearance, Pulse, Grimace, Activity, and Respiration (APGAR) score
Five criteria are scored and each one is scored form 0-2 with a total score of 10, a higher score indicating a better outcome.
Neonate status as determined by Umbilical Artery PH
determined by lab value
Maternal Coagulopathy
determined by lab value

Secondary Outcome Measures

Degree of shivering (severity)
Degree of shivering is measured from 0(no shivering)-3(total body shivering)
Number of patients that need meperidine
Degree of shivering (severity)
Degree of shivering is measured from 0(no shivering)-3(total body shivering)
Number of patients that need meperidine
Degree of shivering (severity)
Degree of shivering is measured from 0(no shivering)-3(total body shivering)
Number of patients that show Maternal thermal comfort
scored form 0-10,a higher number indicating more thermal comfort
Perioperative blood loss
Hospital Length of Stay
