Summary
Brief summary
The aim of this study was to determine the effect of sitting the patient up for 5 minutes after spinal anesthesia before lying down on intraoperative fluid and ephedrine (a medication that raises blood pressure) requirement. We hypothesized that this delayed upright position will minimize the usual decrease in blood pressure after spinal anesthesia and will therefore decrease the amount of fluid and ephedrine usually required to maintain the blood pressure within normal range in these patients.
