PY - 2023 T2 - Obstetric Anesthesia: Quick References & Practical Guides 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 SN - PB - McGraw Hill CY - New York, NY Y2 - 2024/03/28 UR - accessanesthesiology.mhmedical.com/content.aspx?aid=1199674143 ER -
