Where I am, once active labor has ensued, the patient gets her epidural when she requests it. The cervical dilation is of little consequence in this context. If she is being induced, or her cervix is changing, and she is a full admit for labor, she gets it when she wants it. IF labor stalls, we start/titrate pitocin to keep things going.
Also where I am, generally, once the patient has her epidural and she is stable, the MDA goes home or to the sleep room on his/her beeper. (during night shift). ON dayshift, they are always downstairs in the OR, anyhow. Either way, they are there in a flash, should we need them.
CONGRATULATIONS to you, Dutchgirl and best wishes for a healthy, joyous birth experience for your daughter and family.
