Question about pain relievers during labor?

not sure about the half epi thing, do some google research and I'm sure you'll find some stuff....as for the oxygen if its necessary for the baby's well being, ask for the nose tube instead of the full face mask and maybe that will help some of your dizziness and panic attack issues....they generally give you oxygen to help the baby and its often very necessary to help them deal with labor and contractions especially if they start noticing major dips in the heart rate during contractions signalling the baby is not dealing with labor well......I'd definitely take the oxygen to see if it helps.....because if the baby doesn't handle labor well they may start saying the "C" word!!! Otherwise if its not necessary for the baby's well being I don't see why they would even try to give it to you, it really shouldn't be an issue, but discuss it and the reasons it could become necessary so you know better what to expect and your doctor knows what you do and don't want to take place during your birthing experience. Congrats and I hope all goes well :)
