A painless injection for a normal labor will still hurt, but the pain will be lessened. A painless injection for a normal delivery is an injection of anesthetic drugs into the lower back, thus blocking the nerves and providing analgesia. However, it is not completely painless, but rather reduces the pain, more often than not reducing the pain to a tolerable range for the pregnant woman. And smooth labor played painless is not just into the birth of the use of painless medicine, usually in the mouth of the uterus open three fingers or so to play painless injection, before this can still feel the obvious contraction pain. Shunyong labor with painless delivery although it will still be painful, but the degree of pain will be greatly reduced, and will not cause significant impact on the fetus, is a worthy of affirmation of the mode of delivery. Pregnant women should choose the appropriate mode of delivery according to their own situation before giving birth.
