If you do not give birth after the due date, you can take non-drug method or drug method to promote contractions to induce labor, if more than 42 weeks, in order to avoid overdue pregnancy, you should perform early cesarean section to terminate pregnancy, after the due date within 42 weeks of pregnancy, the following measures can be used: a. Non-drug methods 1, appropriate activities: late pregnancy can promote contractions by increasing activities appropriately, such as walking, climbing stairs, etc.; 2, massage breasts:. Moderate massage can stimulate the synthesis and release of oxytocin, thus strengthening contractions; 3, mechanical dilation method: such as low-level water bladder, kombucha strips, seaweed sticks, etc., need to be applied in the absence of vaginal infection and intact fetal membranes, through mechanical stimulation of the cervical canal, promote the synthesis and release of endogenous prostaglandins in the cervical area, while promoting the softening and maturation of the cervical canal and promoting contractions; 4, artificial rupture of membranes: artificial way of intervention to tear The amniotic membrane at the mouth of the uterus, in order to observe the color of amniotic fluid, strengthen contractions, and accelerate the progress of labor. 1. Vaginal administration: Probeson or a small dose of misoprostol placed in the posterior vaginal fornix can promote cervical maturation and speed up labor, but it is prohibited for scarred uterus; 2. Intravenous administration: intravenous oxytocin, the most traditional and widely used, is generally suitable for weak coordinated uterine contractions and is prohibited for uncoordinated uterine contractions. As the placental function gradually declines after 42 weeks of pregnancy, the fetal storage reserve energy decreases, the fetus is often accompanied by fetal distress, the risk of amniotic fluid contamination, at this time should be given timely human intervention, cesarean section to terminate the pregnancy.
