You are an attending obstetrician in charge of a busy hospital. You are monitoring the progress of a woman (gravida 2, para 0) who has been in labor for the past 24 hours; her membranes have been ruptured for 17 hours. Her cervix is 9 cm dilated and 100% effaced, and fetal vertex has reached pelvic floor and is in left occiput anterior position. She has an epidural. The fetal heart rate tracing is reassuring, and an intrauterine pressure catheter shows contractions every 2 to 3 minutes, 50 seconds in duration, and producing 45 mmHg of pressure. Four hours ago, the patient's cervix was dilated 9 cm, was 100% effaced, and fetal station was the same. What is the best next step in management?

A. Outlet vacuum delivery
B. Low forceps delivery
C. Low transverse cesarean section
D. Oxytocin augmentation
E. Penicillin

Penicillin because of 17 hours membrane rupture is the first step.

lscs

The answer is C.
This clinical scenario describes labor dystocia. The patient is gravida 2 but
is nulliparous because she has never had a vaginal delivery. She has had arrest of dilation and descent. She does not meet one of the prerequisites for instrumental delivery (vacuum or forceps), which is a fully dilated cervix. Oxytocin is not necessary because she is having adequate labor contractions as measured by the IUPC. Penicillin would be appropriate if she had ruptured her membranes more than 18 hours and she did not have group b streptococcus vaginal-rectal cultures.
