What kind of condition is abnormal labor and how to diagnose abnormal labor is believed to be a matter of worry for many people, in order to help alleviate your worries, the following is an introduction to the diagnosis of abnormal labor. Normal contractions have a certain rhythm, polarity and consistency, and have a corresponding intensity and frequency. When abnormalities occur, it is called abnormal labor force, which is divided into three types: weak contractions, uncoordinated contractions and hyperactivity, with weak contractions being the most common. Weak contractions often prolong the labor process, such as more than 24 hours, which is called “stalled labor”. The uterus contraction force is weak, the tension is reduced, the contraction duration is short and the interval is long, even during the contraction the uterine wall is not too hard, the mother is mostly uncomfortable, but the labor is too long, mental anxiety and fatigue may occur. If the membranes are not broken, there is no adverse effect on the fetus. For those with strong contractions and a history of emergency delivery, we should strengthen observation and prepare for delivery in advance, and also be prepared to prevent postpartum hemorrhage and neonatal asphyxia. If the contraction is too strong, oxygen inhalation or intramuscular injection of atropine 0.5mg can be given to prevent the fetal life from being affected by placental blood circulation. In case of poor disinfection, both mother and child should be given antibiotics to prevent infection and, if necessary, tetanus antitoxin for infant prophylaxis. Carefully check the birth canal after delivery and closely observe the newborn for intracranial hemorrhage and infection. In the first stage of labor, because of the long time, maternal sleep, rest and diet will be affected by the pain, in order to ensure that there is enough energy to complete the delivery, the mother should try to eat. Food should be semi-liquid or soft food, such as egg noodles, cake, bread, porridge, etc. When entering the second stage of labor, due to frequent uterine contractions, increased pain and consumption, the mother should try to consume some liquid food such as juice, lotus root powder and brown sugar water between contractions to replenish her strength and help the delivery of the fetus. The food during delivery should be high sugar or starchy food that can be quickly digested and absorbed to quickly replenish physical strength. Foods that are greasy, have too much protein or take too long to digest should not be eaten. The former is called “primary contraction weakness” and the latter is “secondary contraction weakness”. The causes and clinical manifestations of the two are similar, but the latter is mostly secondary to mechanical obstruction. Clinical manifestations and diagnosis The following 4 types of abnormal labor progress are common: 1. prolonged latent period. The latent period is from the beginning of labor to 3cm dilatation of the uterus, which normally takes about 8 hours, and if >16 hours is prolonged latent period. 2. Prolonged or delayed active period. The active period is from 3cm dilatation of the cervix to full opening of the uterus. Normal 4-8 hours, such as >8 hours for the active period is prolonged; the progress of the opening of the uterus every hour <1cm, that is, the active period is delayed. 3. Active phase stagnation. After labor enters the active phase, the process of cervical opening dilatation for more than 2 hours without progress is called active phase stagnation. 4.Prolongation or stagnation of the second stage of labor. The second stage of labor is prolonged if the second stage of labor is >2 hours for primiparous women and >1 hour for menstruating women, and the second stage of labor is stalled if the fetal head descends without progress for >1 hour.
