Difficulties in delivery, including shoulder dystocia and malpresentations of the fetus.
Shoulder dystocia is a true obsteric emergency. It may be suspected in large multiparous women, women who have previously delivered large babies, prolonged pregnancy, women who make poor progress in labor, and when the fetus seems very large to palpation. Women with abnormal pelves should be suspect. More liberal use of cesarean section in these situations will reduce the incidence of shoulder dystocia. It is important to have a carefully considered plan of action if shoulder dystocia does occur. The most helpful and definitive maneuver is extration of the posterior arm. Malpresentations cause acute emergencies mainly because of the associated increased incidence of prolapse of the cord. This possibility should be evaluated immediately when rupture of the membranes occurs. Prompt delivery by cesarean section is the treatment of choice with this complications.
