I should remember not to mention complications I haven't had in a while out loud!
Had a mom this weekend who herself weighs nearly 400 lbs. She had very uncomfortable back labor for most of her labor. She eventually requested an epidural as she was exhausted, then she slept for a couple hours, then woke up in transition. For pushing, she greatly preferred hands and knees, and ended up pushing out her baby kneeling. I am sure this would have been a bad shoulder dystocia in a less vertical position. As it was, baby came very slowly after the head, and even after both shoulders were visible, baby was still stuck until finally one arm, then the other popped out (I swear it almost seemed like the baby shoved her hands out on purpose!) Baby was pale and floppy right at birth, but recovered quickly. I'm sure this baby would never have come out with mom on her back; as it was, it was kind of scary. Baby had no problems from her slow, slow entrance to the world, and mom managed to push out this 8 lb 11 oz first baby with no tears whatsoever.
Then, mom proceded to have a massive postpartum hemorrhage, which is another complication I haven't had in a long while.
I'm hoping I'm caught up on complications now, and I'm due for some lovely normal births!
