Antepartum Hemorrhage

Learning Objectives Evaluate patients with antepartum hemorrhage. List differential diagnoses for antepartum bleeding. Manage antepartum hemorrhage safely and promptly. Counsel patients on recurrence risks for antepartum hemorrhage. Antepartum hemorrhage is defined as any bleeding from the genital tract after the 20th week of pregnancy and before the onset of labor. Antepartum hemorrhage complicates 2%–5% of all pregnancies . It is associated with increased rates of perinatal…

Umbilical Cord Prolapse

Learning objectives List risk factors for umbilical cord prolapse. Recognize and manage umbilical cord prolapse. Participate in constructive team debriefing after cord prolapse. Umbilical cord prolapse is a condition in which the umbilical cord presents ahead of the presenting part of the fetus. The umbilical cord will typically protrude into the cervix, vagina, or outside of the body. Cord prolapse is considered an obstetric emergency because…

Breech Extraction of a Second Twin

Learning Objectives Identify indication for breech extraction. Describe technique for breech extraction. Identify potential difficulties encountered during breech extraction Breech extraction has been performed for a long time with different results among the operators. It is usually used to describe the delivery of the second twin with vertex-breech presentations. Breech extraction is preferred over passive delivery of a breech second twin. It is reasonable to avoid…
