Hypotension Clinical Trial
Official title:
The Feasibility of PetCO2 Prediction Hypotension Under Spinal Anesthesia for Cesarean Section
Maternal hypotension is a common side effect after spinal anesthesia for cesarean
delivery.Decreased vascular resistance and cardiac output, due to sympathetic blockade1and
blood pooling in blocked areas of the body respectively, are main causes of spinal
anaesthesia-induced hypotension during Caesarean delivery.
Cardiac output, which has shown to be a better predictor of organ and placental perfusion
than arterial blood pressure.Few studies have measured CO after spinal anesthesia in the
maternal population.This is largely because of the lack of availability of accurate and
reproducible noninvasive measurement techniques. Up to now, preventing hypotension has
continued to focus on arterial blood pressure variables, fluid, and ephedrine requirements
as markers of cardiovascular status, because these are more easily measured.
Investgators hypothesized that CO and PetCO2, in parturients with the degree of hypotension
during spinal anaesthesia, would also have a positive and significant association.
