Prostaglandin gel, artificial rupture of fetal membranes, and oxytocin are discussed.</p><p>If labour is not beginning or progressing as it should, your health-care provider may want to induce or enhance your contractions. Believe it or not, nipple stimulation or sexual intercourse can sometimes be an effective way to get those contractions going! However, sometimes other measures are needed. These may include application of prostaglandin gel, artificial rupture of the fetal membranes, or administration of a drug called oxytocin. </p><h2>Key points</h2> <ul><li>Labour may have to be induced if your baby is not thriving in the womb, the placenta has stopped working properly or if your pregnancy is overdue.</li> <li>A health-care provider can induce labour by administering prostaglandin gel to the cervix, artificially breaking the amniotic sac or giving synthetic oxytocin intravenously.</li></ul><p>There are a number of situations where your health-care provider might ask you to consider having labour induced: </p> <ul> <li>if your baby is not thriving in the womb, and is mature enough to survive in the outside world </li> <li>if the placenta has stopped working properly, reducing the baby’s nutrient supply </li> <li>if the fetal membranes have ruptured prematurely, which causes amniotic fluid to slowly seep out of the womb and puts the baby at risk of infection </li> <li>if your pregnancy is overdue </li> <li>if you have diabetes and a very large baby that will be difficult to deliver </li> <li>if you have uncontrolled pregnancy-induced hypertension or another illness that is threatening your well-being or the health of your baby </li> <li>if your baby has severe rhesus (Rh) hemolytic disease, where your Rh antibodies are attacking your baby’s red blood cells </li></ul> <h2>Prostaglandin gel</h2> <p>Prostaglandin gel can be used when the cervix is less than 3 cm (1 inch) dilated. This gel is administered to the cervix through a syringe placed in the vagina. The drug helps the cervix dilate so that the birth canal can form. The contractions should begin slowly, and you may be able to go back home for a few hours after the gel has been put in place. </p> <p>In some women, prostaglandin gel alone can be enough to stimulate the cervix to open. In other women, a drug called oxytocin must be added to get the contractions started. Sometimes the gel can lead to extremely strong contractions that are dangerous to the mother and baby. In these cases, the gel, which is attached to a string, can be pulled out of the vagina. Because of the potential for extremely strong contractions, prostaglandin gel is never used to enhance contractions in a labour that has already started. </p> <h2>Artificial rupture of the fetal membranes</h2> <p>Sometimes the doctor will choose to artificially break your amniotic sac in order to get labour going or to make the contractions stronger. The doctor will use something that looks like a crochet hook to make a small tear in the membrane. Amniotic fluid, which formed a protective cushion for the baby during pregnancy, begins to seep out of the womb and should, in theory, begin labour. </p> <p>Artificial rupture of the membranes is a common procedure but there is some controversy over whether it really helps. Sometimes this procedure does not cause the contractions of labour to start. The amniotic fluid continues to seep out of the womb, and therefore the baby loses their protective cushion. If labour contractions do not start, another form of induction, such as oxytocin, will be required. Also, artificial rupture of the membranes increases the risk of an infection of the fetal membranes and amniotic fluid, called chorioamnionitis. </p> <h2>Oxytocin</h2> <p>Some women need extra help from a hormone called oxytocin, which is made naturally in the pituitary gland throughout pregnancy. Oxytocin triggers the contractions of labour, although the exact way in which it does this is not yet known. When given synthetically, oxytocin can jumpstart labour or make the contractions stronger. </p> <p>Synthetic oxytocin is given intravenously through a needle. An infusion pump is used to control the dosage. At first, small amounts of oxytocin are infused. The dose is increased every 30 to 45 minutes until the contractions are strong and effective, which may take several hours. </p> <p>Oxytocin is a powerful drug that usually acts immediately. Generally, when women are given oxytocin, they notice a major increase in the pain and frequency of their contractions. If oxytocin does not cause the cervix to dilate properly during that time, the drug should be discontinued and a caesarean section may be required. </p> <p>In order for oxytocin to be used, the unborn baby must be in good health. There are a number of circumstances where oxytocin should not be given, such as the following: </p> <ul> <li>if your baby is not in the traditional head-down position in the womb </li> <li>if the baby is extremely large </li> <li>if you have had six or more previous births, because of the increased risk of uterine rupture</li></ul> <p>If you are given an oxytocin infusion, you should never be left alone by medical personnel. Your contractions and your baby’s heart rate should be monitored continuously. The drug will likely be discontinued if you start having more than five contractions in a 10-minute period, or lasting longer than one minute in duration. Oxytocin will also be discontinued if the baby’s heart rate drops significantly. </p>https://assets.aboutkidshealth.ca/AKHAssets/labour_induction.jpgLabour induction
