In the 39th week of pregnancy, you should try not to give oxytocic injections to assist labor without the indication of induction of labor. The main component of oxytocic injection is contractin, also called oxytocin, which excites the smooth muscle of the uterus and causes uterine contractions, allowing the pregnant woman to enter labor early. When the uterine contractions are irregular, the fetus may suffer from intrauterine hypoxia and immature fetal lungs, which may also lead to placental abruption and severe bleeding in pregnant women. When oxytocin is dripped too fast or given too much, it will cause tonic or spasmodic uterine contractions. If the resistance to delivery is not too great at this time, the fetus will usually be delivered quickly, which will easily cause birth canal lacerations and complicate postpartum infections, etc. Usually, the contractions will start on their own at the latest around 40 weeks of pregnancy. At 39 weeks of pregnancy, pregnant women can naturally wait for contractions and prepare to enter labor. At this time, pregnant women can use some natural ways to induce labor, such as walking for half an hour every day, slowly going up steps, gently massaging the abdomen, etc., but they need to do it under the guidance of doctors and when accompanied by family members to avoid accidents. Of course, if there is no sign of labor at 41 weeks of pregnancy, the pregnant woman can be induced artificially under the advice of the doctor, but the fetal heartbeat and the vital signs of the pregnant woman need to be closely monitored.
