Key result
Norepinephrine matches phenylephrine for maternal hypotension rescue with less bradycardia and greater cardiac output.
Why the study?
Phenylephrine is the current gold standard vasopressor for maternal hypotension during spinal anesthesia for cesarean delivery but is associated with dose-dependent reflex bradycardia and decreased cardiac output, prompting investigation of norepinephrine as a potential alternative.
Does norepinephrine improve hemodynamics and reduce bradycardia compared to phenylephrine in pregnant women undergoing elective cesarean delivery under spinal anesthesia?

Norepinephrine matches phenylephrine efficacy for cesarean spinal hypotension while reducing bradycardia and preserving cardiac output; extends RCT evidence for its use as alternative.
Does norepinephrine improve hemodynamics and reduce bradycardia compared to phenylephrine in pregnant women undergoing elective cesarean delivery under spinal anesthesia?
Norepinephrine is a promising alternative to phenylephrine for treating maternal hypotension during cesarean delivery, maintaining cardiac output with less reflex bradycardia.
Wang et al. (2018) conducted a review in Maternal hypotension during elective cesarean delivery under spinal anesthesia. Norepinephrine vs. Phenylephrine was evaluated on Maternal hypotension rescue, adverse outcomes, bradycardia, and cardiac output. A review of 9 reports found norepinephrine had similar efficacy to phenylephrine for rescuing maternal hypotension, with a lower incidence of bradycardia and greater cardiac output.
