The first time you have a contraction during fetal monitoring, it is usually a physiological contraction, but it may also be related to preterm labor or labor. The specific situation is different and the way to deal with it is also different.1. Physiological contractions: If a contraction occurs occasionally when doing fetal heart monitoring, it is often a physiological contraction. Usually the number of contractions is small and irregular, no special treatment is needed in this case, and regular labor check can be done; 2. Premature labor: before 37 weeks of pregnancy, regular contractions occur during fetal heart monitoring, the lower abdomen becomes soft and hard repeatedly, and the muscles also have the feeling of hardening and swelling, at least 1-2 contractions every 10 minutes, lasting for more than 30 seconds, and accompanied by continuous pain, and a small amount of vaginal bleeding, suggesting Preterm labor may be indicated. In this case, medication can be applied to suppress contractions to prolong the gestational cycle to promote fetal lung maturation, while paying attention to bed rest and avoiding strenuous exercise. In case of intrauterine infection or fetal distress, the pregnancy should be terminated in time; 3.Production: After 37 weeks of pregnancy, when regular and gradually increasing contractions occur during fetal heart monitoring, lasting 30 seconds or more with an interval of 5-6 minutes, accompanied by the disappearance of progressive cervical canal, dilatation of the uterine orifice and descent of the fetal first dew, it means that the mother has entered into labor. At this time, you should make good preparations before delivery, avoid excessive emotional tension and anxiety, and eat or rest appropriately between contractions to preserve your strength for later delivery.
