Call him up asap (either sunday if he via beeper at a reasonable time) or monday 8:00am, and get her to a OB/GYN that morning. From what you've told me, here is my guess:
Many hospitals, especially those in rural and semi-rural areas (and even a few larger areas), no longer have a OB/GYN (Gynocologist) on staff. The malpractice drove them all to other areas or to retirement. For most deliveries, they could be done by family physicians or by ER doctors without much trouble, even C-Sections. That being said, neither of these have experience in complicated deleveries, especially when there is significant tramau to the mother.
This lady needs to be seen by a OB now.
All of the above being said, I'm not a doctor at the scene, and he is. I would push to make sure she doesn't get "forgotten in the wash," but it sounds like the referral is already in the works.
