A 25-year-old G2 P1 woman is delivering at 42 weeks’ gestation. She is moderately obese, but the fetus appears clinically to be of about 3700 g weight. After a 4-hour first stage of labor, and a 2-hour second stage of labor, the fetal head delivers but is noted to be retracted back toward the patient’s introitus. The fetal shoulders do not deliver, even with maternal pushing. What is the best next step in the management?
