Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
pregnant patients undergoing cesarean section under spinal anesthesia will be randomly allocated into two groups. Control group will be hydrated with single dose 15ml/kg of intravenous crystalloid solution at room temperature and study group will be hydrated with single dose 15ml/kg of intravenous crystalloid solution at body temperature (37 degrees celsius) by the anesthesia nurse of the operation room following administration of spinal anesthesia (following the removal of spinal needle in 5 minutes). The temperature of the infusion fluid will be kept constant using a warming device.

Outcomes
Primary outcome [1] 305656 0
maternal hypotension, assessed with a non invasive blood pressure from the left arm measured at the acceptance of patient to operation room and every minute for 10 minutes following induction of spinal anaesthesia [primary timepoint] then every 5 minutes till 30 minutes or at the end of surgery. hypotension is defined as a 20% decrease of basal blood pressure.
Timepoint [1] 305656 0
basal blood pressure will be measured after the patient is accepted to the operation room. blood pressure will than be measured every minute for 10 minutes following induction of spinal anaesthesia [primary timepoint] then every 5 minutes till 30 minutes or at the end of surgery.
Primary outcome [2] 305657 0
maternal bradycardia, assessed with the electrocardiography on the monitor. bradycardia is accepted as a heart rate lower than 50 beats per minute.
Timepoint [2] 305657 0
heart rate will be monitorized beginning with the acceptance of the parturient to the operation room until the end of surgery.
Secondary outcome [1] 346054 0
fetal apgar score (an index used to evaluate the condition of a newborn infant based on a range of 0, 1, 2 for each of the five characteristics of color, heart rate, response to stimulation of the sole of the foot, muscle tone, and respiration with 10 being a perfect score)
Timepoint [1] 346054 0
assessed by a pediatrician at first and fifth minutes after birth.

Summary
Brief summary
hypotension is a common occurance in parturients undergoing cesarean section with spinal anesthesia. several modalities have been tested to prevent or decrease the degree of hypotension in paturients during cesarean section under spinal anesthesia. In the recent studies, coloading with crystalloids is reported to be superior than preloading with crystalloids. The current study is conducted to determine the effect of isothermic coloading with crystalloid fluid on maternal vital signs and fetal apgar scores.
