Induced labour operation is that many women in late pregnancy, due to some factors must be pregnancy termination in case of use. But they just follow the doctor's guidance, the operation method is not very understand. So what is the induced labour operation? It is a particularly painful operation, in the fetus was large, with artificially induced uterine contraction and the end of pregnancy.
Induction of labor is in pregnancy16-24weeks using drugs or water bag method, fetal and its appendages from in vitro, the termination of pregnancy method. It is curettage operation is more complicated, the greater the danger. Operation prior to nutritional supplements, to avoid the cold, acute inflammation to take control of inflammation after operation.
Induced labour operation method:
In 1, the drug reduced placental hormone secretion : the application of drugs that act directly on the trophoblast cell, make its degeneration, thus the placental function, human chorionic gonadotropin and progesterone secretion is reduced, progesterone after inactivation, allowing in vivo prostaglandin release from inhibition, leading to miscarriage. Trichosanthin, rivanol and hypertonic saline solution can cause trophoblastic cell necrosis.
2, drug stimulation of uterine contractions: normal pregnancy, progesterone and prostaglandin in a state of equilibrium, not easy to induce uterine contractions, particularly in the second trimester of pregnancy when the equilibrium state is more stable, i.e., using the general contraction drugs such as oxytocin is also very difficult to elicit effective contraction. Exogenous drugs strengthen the advantage of prostaglandin, breaking this balance, can cause rhythmic contractions leading to abortion.
In 3, the mechanical stimulation of uterine contractions: including the dramatic increase in uterine volume and mechanical stimulation of the cervical canal elicits a reflex contraction, hypertonic saline or other high solution into the amniotic cavity so that they belong to the former water surge. In utero drainage bag, hand an increase in intrauterine pressure, but also stimulate the cervix tube. Gelatin sticks, bougie, intrauterine placed catheters are the mechanical stimulation of uterine contraction.
Reminder: the above is a specific presentation of induced labor operation, believe that women on the operation method is also a certain understanding, this can be avoided and operation at the time of fear, the operation is very favorable.
