Prediction of Spinal Anesthesia-Induced Hypotension in Cesarian Section: Carotid Artery-Corrected Flow Time Versus Cardiometry

Prediction of Spinal Anesthesia-Induced Hypotension in Cesarian Section: Carotid Artery-Corrected Flow Time Versus Cardiometry: Randomized Controlled Trial

This research aimed to evaluate and compare the role of carotid corrected flow time (FTc) and electrical cardiometry (EC) in the prediction and prevention of post-spinal hypotension in elective cesarian section.

Spinal anesthesia is the procedure of choice for elective cesarean section (CS) because it avoids the most common side effects related to general anesthesia, such as the risk of aspiration, airway problems and the negative effects of intravenous anesthetic drugs on the fetus.

Accurate prediction of post-spinal hypotension could enhance clinical decision-making, optimize management, and facilitate early intervention. More than thirty predictors were used in the prediction of post-spinal hypotension including demographic data, hemodynamic variables, postural stress testing, peripheral perfusion indices, volume and fluid responsiveness indices, and genetic polymorphism.

The baseline parameters obtained via the bioreactance-based system may serve as a predictor of post-spinal anesthesia hypotension in parturient.
