Investigation of the Optimum Baseline Blood Pressure for Spinal Anesthesia to Guide Vasopressor Management for Elective Cesarean Delivery: A Case-Control Design

Background: Current guidelines recommend prophylactic vasopressor administration during spinal anesthesia for cesarean delivery to maintain intraoperative blood pressure above 90% of the baseline value. We sought determine optimum mean arterial (MAP) reading guide management hypotension. Methods: performed a secondary analysis data collected from normotensive patients presenting elective in tertiary care institution October 2018 August 2020. compared magnitude hypotension who reported nausea versus those did not, using case-control design. Baseline MAPs at last office visit, morning surgery, or operating room (pre-spinal) were determined. calculated duration and degree area under curve (AUC) when MAP respective patient was below each baseline. Results: The experienced (n=45) had longer more profound periods than not develop (n=240). A comparison AUC visit on surgery showed statistically significant between-group difference, P=0.02, P=0.005, respectively, no difference used. Conclusions: Patients highest preoperative similar with without pre-spinal Therefore, maintaining higher individual as should reduce maternal nausea.
