Can pregnant women take oxytocin? 1 What is oxytocin?
Oxytocin, also known as oxytocin, is a hormone with the functions of "inducing labor before delivery, inducing labor during delivery, promoting lactation after delivery and stopping bleeding". Oxytocin can also reduce the level of stress hormones such as adrenaline in human body, thus lowering blood pressure. In addition, it is pointed out that when people are in a happy mood or have a strong sense of belonging, the heart will also produce oxytocin, and the oxygen supply of tissues in the body will be greatly increased, which has the effect of relieving stress.
Oxytocin is naturally secreted by neurons in the "paraventricular nucleus" and "supraoptic nucleus" of human hypothalamus, that is, expectant mothers can give birth to oxytocin by themselves. However, many expectant mothers will have panic and anxiety during childbirth, or their own diseases will affect the secretion function of oxytocin. Oxytocin should be used according to the actual situation at this time.
The main function of oxytocin is to excite uterine smooth muscle, thus forming uterine contraction. The results show that if a reasonable dose of oxytocin is injected during the delivery of expectant mothers, it can play a good role in inducing labor. So, will expectant mothers take oxytocin? The use of oxytocin is not "immediate", but generally takes effect a few hours after oxytocin is used and before labor, and the use of oxytocin should be combined with the endocrine, mental and drug use of expectant mothers. Therefore, whether oxytocin is needed or not should be examined in detail.
Side effects of oxytocin
1, oxytocin causes uncoordinated uterine contraction or excessive contractility, resulting in fetal hypoxia in the uterus. And in the case of uncoordinated uterine contraction, the labor process is accelerated or even stopped.
2, causing uterine rupture, if the doctor injects oxytocin in the case of maternal pelvic stenosis or even abnormal fetal position, the contractility of the uterus will be greatly enhanced. In this case, the fetus cannot pass through the birth canal, resulting in uterine rupture.
Effect of Oxytocin on Fetus
The effect of oxytocin injection by expectant mothers on the fetus is not obvious. But if the dripping speed is too fast and the drug intake is too high, expectant mothers will have tonic or spasmodic contractions. In this case, if the birth canal is narrow, the fetus is too large, and the fetal position is abnormal, it will affect the fetal descent, which will eventually lead to thinning of the lower uterus, massive bleeding of the expectant mother, insufficient support and fetal hypoxia.
In the above situation, if the uterine contraction intensity is too large and the labor resistance is not great, the fetus can be delivered quickly, and the labor process is less than three hours, that is, there is an urgent labor situation. By comparison, postpartum infection, birth canal rupture, baby falls and other serious consequences are caused by untimely perineal disinfection.
In the case of prolonged uterine contraction or even no intermittent contraction, the blood circulation of placenta will be affected, and the fetus in uterus will suffer from acute hypoxia, stillbirth or fetal asphyxia.
Can pregnant women take oxytocin? Under what circumstances do they need oxytocin?
At present, oxytocin is still used as medicine rather than health care products, so it is forbidden to abuse oxytocin. The correct use of oxytocin is related to the life safety of parturient and fetus. Different parturients have different reactions to oxytocin, so the use of oxytocin must be clear, reasonable and strict.
1, under what circumstances should oxytocin be given?
(1) Prenatal labor induction: Oxytocin can be used when the expectant mother needs to terminate her pregnancy, such as abortion, fetal malformation, fetal growth retardation, overdue pregnancy, hemolysis, placental dysfunction, etc. Before delivery, full-time doctors will decide the timing of induced labor according to fetal movement, fetal heart monitoring and B-ultrasound amniotic fluid volume. Amniotic fluid depth
(2) Postpartum lactation: When a woman is breastfeeding, the mammary gland can continuously secrete a large amount of milk under the action of oxytocin and store it in mammary gland acinus. At this time, oxytocin makes myoepithelioid cells around mammary gland acinus contract, and promotes milk ejection of mammary gland;
(3) Oxytocin during labor: If the expectant mother contracts the uterus during labor, the amniotic fluid is discharged, and the fetus has not landed for a long time, oxytocin can be injected. In addition, oxytocin is also needed in the case of weak contractions and uncoordinated contractions. The dosage of oxytocin should also be used in strict accordance with the drug instructions to achieve ideal delivery;
(4) Hemostasis: Oxytocin has the same hemostatic function as bandage, and its principle is very similar, mainly by applying external force to damaged blood vessels to achieve the purpose of hemostasis. After injection of oxytocin, the myometrium of uterus slowly contracts under the action of drugs, and the contraction force will seal the open blood vessels in the uterine cavity and prevent blood from flowing out.
2. Under what circumstances can't oxytocin be given?
(1) Malposition: The position of the fetus in the uterus is called fetal position. When the longitudinal axis of the carcass is parallel to the longitudinal axis of the mother, the fetal head is bent at the pelvic entrance, the chin is close to the chest wall, the spine is slightly bent forward, and the limbs are bent across the chest and abdomen. The carcass is oval, which is called occipital anterior position and is regarded as normal fetal position. The rest of the fetal position is abnormal. Improper carcass will lead to dystocia during delivery, and under normal circumstances, surgical assistance is needed;
(2) Placenta previa: When the expectant mother is pregnant for 28 weeks, the placenta adheres to the lower part of the uterus or reaches or covers the cervix at the lower edge of the placenta. If the position is lower than the fetal presentation, it belongs to placenta previa. Placenta previa may lead to the risk of severe bleeding during pregnancy, and may also increase the risk of bleeding during and after delivery. Therefore, when the placenta returns to its normal position, it should be used as appropriate;
(3) Pelvic abnormalities: Female pelvic abnormalities can be caused by genetic factors and environmental factors. Abnormal pelvic bone can hinder the physiological process of fetal head entering the basin, joining, descending and pronation, resulting in dystocia. If found in time and handled properly, dystocia can be transformed into normal delivery, allowing pregnant women to give birth naturally and reducing the rate of cesarean section.
In addition, if the expectant mother has uterine scar, cervical cancer, acute inflammation of reproductive tract, etc. , not suitable for oxytocin induced labor and induced labor.
Effect of Oxytocin on Fetus
The effect of oxytocin injection by expectant mothers on the fetus is not obvious. But if the dripping speed is too fast and the drug intake is too high, expectant mothers will have tonic or spasmodic contractions. In this case, if the birth canal is narrow, the fetus is too large, and the fetal position is abnormal, it will affect the fetal descent, which will eventually lead to thinning of the lower uterus, massive bleeding of the expectant mother, insufficient support and fetal hypoxia.
In the above situation, if the uterine contraction intensity is too large and the labor resistance is not great, the fetus can be delivered quickly, and the labor process is less than three hours, that is, there is an urgent labor situation. Finally, due to the untimely disinfection of perineum, postpartum infection, rupture of birth canal, baby fall and other serious consequences.
When the uterus continues to contract for too long, even if there is no intermittent contraction, the blood circulation of the placenta will be affected, and the fetus will have acute hypoxia, stillbirth or fetal asphyxia.
Precautions for using oxytocin
The use of oxytocin is a very professional and flexible process and should be carried out by full-time doctors. However, as expectant mothers and their families, it is best to know how to use oxytocin, so as not to see doctors worried and afraid to ask when giving their mothers an injection. Pay attention to the following situations when using oxytocin.
1, improper use of oxytocin will lead to serious consequences of uterine rupture, so full-time doctors need to master the dosage and timing of oxytocin;
2, the use of oxytocin should pay attention to the right time, should not be too early or too late, if the cervix has not been fully opened, you can use prostaglandin to open the cervix to the right university. In addition, the late use of oxytocin will lead to the physical decline of expectant mothers, the burden is too heavy, and it is impossible to give birth safely. Therefore, we must seize the opportunity;
3. Before using oxytocin, we must conduct a comprehensive medical history inquiry and examination, strictly grasp the indications, and investigate contraindications;
4. If you have chest tightness, chills, urticaria or even shock during use, stop using it and rescue it to prevent it from being used too fast;
5. Expectant mothers who failed to induce labor with oxytocin on the same day can repeat or switch to other methods to induce labor.
