Vasopressor Prophylaxis After Spinal Anesthesia

Overview

Norepinephrine has been recently introduced as a prophylactic vasopressor during Cesarean delivery with promising results ; However, the optimum dose for efficient prophylaxis with the least side effects is not known. In this study, we will compare three doses (0.05, 0.1, 0.15 mcg/Kg/min) of norepinephrine for prophylaxis against Post-Spinal hypotension during cesarean delivery.

Maternal hypotension is a common complication after spinal anesthesia for cesarean delivery (CD). Using vasopressors have been considered a gold standard for prevention of post-spinal hypotension (PSH) during CD. Norepinephrine (NE) is a potent vasopressor characterized by both α adrenergic agonistic activity in addition to a weak β adrenergic agonistic activity; thus, NE is considered a vasopressor with minimal cardiac depressant effect; these pharmacological properties would make NE an attractive alternative to phenylephrine and ephedrine (the most commonly used vasopressors in obstetric anesthesia). Norepinephrine has been recently introduced as a prophylactic vasopressor during CD with promising results; However, the optimum dose for efficient prophylaxis with the least side effects is not known. In this study, we will compare three doses (0.05, 0.1, 0.15 mcg/Kg/min) of norepinephrine for prophylaxis against PSH during CD.
