If you're anything like me, being trapped during labor sounds like the worst thing in the world.
Now, if you chose to have your baby at home or in a birthing center, you won't need to worry about that at all.
But if you are in a hospital, be it for personal reasons or insurance reasons (as was our case ... sigh), you will have to face being trapped. Whether you are asked to stay in bed or not, all hospitals prefer to have quick access to those veins of yours. Hospitals are always trying to prepare for the worst, and so will want to be able to shoot whatever they need to into your body at a moment's notice. Having several nurses in my family, I know that opening up a vein is not always the easiest thing, and so is preferably done before any emergency pops up.
So, will you need to be stuck to a pole with tubes running into your arm?
Ask for a "heplock".
It's another one of those compromises ladies wanting a natural birth in a hospital will likely need to make.
