38 weeks gestation, admitted to the delivery for management of labor.
Active labor for 4 hours. Cervical dilation progressed from 3-8cm and Descent progressed from -1 to +1 Station. 6 hours later there is the same degree of dilation and descent.
Fetal head is in LOA position. External tocometer shows contractions are 3 minutes apart lasting 50 seconds each. Internal pelvic assesment shows prominent ischial spines. Fetal heart rate is 140bpm with frequent accelerations. Prenatal U/S at 37 weeks showed a fetus of average size. Next step?

A. Forceps Delivery
B. Low Transverse C-section
C. Administer Oxytocin
D. Close observation for 2 more hours.
E. Zavanelli Maneuver

Please answer and explain why.
Thanks.

B the pte have midpelvis contraction evidenced by "Internal pelvic assesment shows prominent ischial spines" so that's an arrest in labor (specifically arrest of dilation) and the next step is c-section

B Same concept DRVirgo, you are really nailing down the concepts, good for you.

  #4

watch 2 hrs more....prominent iscial spine is given to distract you....0 station is the ischial spine...fetus at +1 shows it crossses spine....if not after 2 hr.,do instrumentation

  #5

it can be foreceps delievery

  #6

The head is engaged already, so no CS is applicable. No reason to observe for 2 more hours, so I would go for A.

  #7

b low transverse c/s ..arrest in active phase due to prominent ischeal spine
