In contrast to what many people think, fainting during labor is extremely rare. When it comes to childbirth, nature has designed the female body in such a way that it mobilizes all of its energy. Passing out during childbirth is not an unusual reaction of a woman's body. If a patient is unconscious during birth and cannot push, it is extremely difficult for them to give birth. Generally, doctors use an IV to strengthen contractions – which is oxytocin administered by the doctor.
