Before midwifery, the midwife first disinfects the vulva of his hands, arms, and cows with potassium permanganate solution, then puts his hand into the cow's birth canal to determine whether the fetal position is normal. If not, push the fetus back first. Uterus, correction of fetal position. Afterwards, the fetus's two forelimb branches are tied with a sterile midwifery chain or rope and pulled by the assistants. The midwifery's hands are inserted into the birth canal and the thumb is inserted into the fetus's mouth, and then the forehead is clamped. When the fetus is pulled outwards, avoid deadlift damage to the cow's birth canal or damage to the forelegs of the fetus. When the fetus passes through the vulva, one person must use both hands to secure the cow's labia and perineum and prevent the fetus from cracking her mouth. After the fetal head is pulled out, it must be pulled slowly to avoid uterine varus or prolapse. When the fetus's abdomen passes through the vulva, it is necessary to remove the fetus by hand so as not to directly damage the fetus. After the fetus is produced, it is cut with sterile scissors 8 to 10 cm from its abdomen, and then sterilized with iodine at the broken end.
