Y1 - 2023 N1 - T2 - Obstetric Anesthesia: Quick References & Practical Guides AB - Approximately 3% to 4% of term fetuses present breech. Vaginal breech delivery is associated with excess risk of neonatal near miss and perinatal morbidity and mortality, compared with vaginal cephalic delivery. External cephalic version (ECV) is the manual rotation of the fetus’ head to a cephalic presentation to achieve cephalic vaginal delivery and decrease cesarean delivery (CD) rates. ECV is successful about 58% of the time (40% for nulliparous and 64% for multiparous). A successful version decreases the risk of CD by about 40% in this patient population. Table 52-1 lists factors that influence success of ECV. SN - PB - McGraw Hill CY - New York, NY Y2 - 2024/04/19 UR - obgyn.mhmedical.com/content.aspx?aid=1199674178 ER -
