Each year, about 1 in 4 women give birth after one work indus, which is the artificial challenge of giving birth for medical reasons. Most of the time, a woman gives birth to her baby after 40 weeks of pregnancy, as long as the pregnancy period lasts.
However, there are situations in which future mothers reach 41 or 42 weeks of pregnancy without any sign of the baby that they would like to come into the world. Waiting becomes stressful for future mothers, especially if they are at their first pregnancy.
Induced labor, at post-term birth
A 42 week past pregnancy is an outdated or post-term pregnancy. As the pregnancy exceeds 42 weeks, both the risks for the fetus and those for the pregnant woman increase. For example, the placenta may no longer be as effective in providing nutrients to the fetus, increasing the risk that the fetus will be born dead. To avoid any complications, the doctor may recommend the induction of labor of a pregnant woman.
Another situation when it can be recommended induced labor is when the water breaks, but the pregnant woman has no contractions. In this case, artificial stimulation of labor is recommended, because there is a higher risk of infection for the baby, but also for the mother, in the uterus.
Also, if the doctor has noticed following investigations that the placenta is no longer functioning properly, that there is too little amniotic fluid or that the baby is not growing or not growing as much as he should, he can resort to induced birth.
In what other situations is induction of labor recommended
• in case of pre-eclampsia, a serious condition that can endanger the health of the pregnant woman. Also, this condition can restrict the blood flow to the fetus;
• death of the fetus in the womb;
• twin pregnancy that has passed for 38 weeks;
• in women who have kidney disease, but also in the case of gestational diabetes and high blood pressure;
• in case of obesity.
Induction of labor It is not a recommended procedure before turning 39 weeks of pregnancy because it increases the risk of complications in the baby, such as respiratory difficulties, infections or jaundice. The procedure is not used in women suffering from placenta previa, if the baby is positioned transversely in the mother's uterus, if tests have been performed that have shown that the fetus cannot withstand contractions or if there is an active genital herpes infection . Even women who have undergone a caesarean section cannot use this method for the second birth.
By what methods labor is induced
For labor induction There are several methods, some more commonly used, others less often, from the use of drugs to mechanical approaches.
The mechanical methods that can be used by the gynecologist include amniothymia, ie artificial rupture of the membranes. The doctor uses a tool called a cniper to break them, but they can also be broken with the finger. The method is used only if the woman has a dilatation of at least a few centimeters and if the pregnancy has come to an end.
Artificial removal of the membranes is the method the doctor uses if there is dilatation, being a procedure in which the doctor inserts an index into the cervix of the pregnant woman, then moves her finger around the cervix to separate the membranes from the amniotic sac where the fetus is. As a result of these movements, prostaglandins begin to be released which lead to stimulation of labor.
The use of oxytocin or prostaglandin is indicated for labor induction, because it helps trigger contractions. Prostaglandin can be given as tablets, orally or as a gel that is inserted into the vagina. Oxytocin is given intravenously, being indicated if labor has a very slow evolution. It is given first in very small quantities and then the dose is increased progressively, every 20-30 minutes.
Other substances that can be used for labor induction They are mifeprostone, an agent that helps stimulate uterine contractions, misoprostol, an agent that helps to prepare the cervix for birth, but also relaxin, a hormone also used to stimulate the cervix of the pregnant woman.
Using a Foley catheter is another method by which your doctor will induce labor. The method involves the introduction of a catheter, an instrument that at the end is provided with a small, inflated balloon in the cervix. When the balloon reaches the cervix area, the doctor begins to fill it with water, so as to put pressure on the cervix and force it to open, so that contractions can be triggered.
There are also methods that have not been scientifically proven to induce labor:
• natural remedies, such as cucumber-cucumber oil or black-coosin;
• sexual intercourse, because after vaginal penetration the lower uterine segment is stimulated, releasing prostaglandins, substances that help the cervix to prepare for birth. At the same time, the female orgasm can trigger contractions;
• nipple stimulation and breast massage.
A pregnant woman must know that usually one work indus it is more painful than a natural labor. Epidural anesthesia can be used to relieve pain. In general, labor induction is a safe method, but complications such as infections, uterine rupture, high blood pressure can occur not only in the mother, but also in the fetus, but also in lowering the blood sodium level.
In some cases (about 25%) the birth may not work, so the doctor will choose a cesarean section to bring the baby to the world.
Induction of labor it can take from several hours to 1, even 2 days, which means that both the future mother and the partner must be patiently armed.
