AB As  discussed  in  other  chapters,  neuraxial  anesthesia  is  the  most  common  and  preferred  anesthetic  for  cesarean  delivery.  Induction  of  spinal  anesthesia  causes  a  sympathectomy  leading  to  vasodilation  and,  rarely  bradycardia,  resulting  in  maternal  hypotension.1  Avoiding  hypotension  in  parturients  is  important  as  the  human  placenta  has  minimal  autoregulation,  and  fetal  perfusion  is  determined  solely  by  maternal  perfusion  pressure.  Although  serious  adverse  events  resulting  from  hypotension  are  uncommon,  hypotension  following  spinal  anesthesia  induction  is  associated  with  maternal  nausea  and  vomiting,  with  fetal  heart  rate  (HR)  changes,  and  prolonged  hypotension  can  lead  to  fetal  acidosis.2
