Brief Summary

The goal of this clinical trial is to learn if norepinephrine is more effective than phenylephrine for prevention of spinal anesthesia induced hypotension. The main questions it aims to answer are: Does norepinephrine lower the incidence of spinal anesthesia induced hypotension in emergency obstetrical patients? We will compare effectiveness of norepinephrine and phenylephrine for the prevention of spinal anesthesia induced hypotension. Participants will: Be administered prophylactic boluses of both drugs right after spinal anesthesia induction and maternal hemodynamic parameters and neonatal APGAR scores will be recorded
