Summary
Norepinephrine has emerged as a potential alternative for stabilizing blood pressure during spinal anesthesia for cesarean section, purportedly maintaining maternal heart rate and cardiac output more effectively than phenylephrine. However, its application as an intravenous bolus for treating hypotension remains underexplored. Consequently, this current investigation aimed to determine the ED50 and ED95 of norepinephrine for managing maternal hypotension during cesarean section. A prospective trial enrolled 100 patients undergoing elective delivery under spinal anesthesia, with norepinephrine dosage determined using the upper and lower sequential distribution method (UDM).
