Undetectable Hypotension Episodes in Cesarean Section

In order to evaluate the efficacy and necessity of continuous non-invasive arterial pressure (CNAP) by comparing it with non-invasive blood pressure (NIBP) in order to understand whether it has advantages over oscillometric technique for detection of hypotensive episodes in healthy pregnant women who underwent cesarean section (C/S) under neuraxial anesthesia. This prospective study will evaluate healthy pregnant women at term, who were scheduled for elective C/S under spinal anesthesia. Subjects were randomly assigned into 2 groups to receive either CNAP and NIBP or only NIBP. A thirty percent decrease in systolic blood pressure from either baseline or the measured values in the first two minutes, or if the systolic blood pressure was less than 90mmHg, is considered hypotension. Pre-, peri- and post-operative specifications, newborn characteristics, and complications were recorded and compared.
