Oxytocin is a common drug used to induce labor in late pregnancy. Usually, women need to be hooked up for 4-8 hours before regular contractions occur, but different pregnant women respond differently to oxytocin. If a woman is sensitive to oxytocin, she may experience regular contractions in 1-2 hours, while a woman who is not sensitive to oxytocin may take 6-12 hours. During the application of oxytocin, it is necessary to listen to the fetal heartbeat regularly to ensure that it is normal, which is 110-160 beats per minute. If the fetal heart rate continues to increase or decrease significantly, there may be acute intrauterine distress and oxytocin needs to be discontinued. Therefore, pregnant women and their families should pay close attention to monitoring the fetal movement and inform the medical staff if the fetal movement is too frequent or significantly reduced. In addition, during the application of oxytocin, the pregnant woman appears vaginal bleeding, fluid, redness increased significantly, it is recommended to timely notify the doctor, under the guidance of the doctor, improve the relevant examination, to clarify whether it is about to give birth, and to take appropriate measures to deal with the situation.
