What symptom does dystocia have?

summary

Before the occurrence of any disease, there will be signs, as long as we patiently observe, it will be easy to summarize its symptoms. Experts say that if dystocia is a disease that harms both people and ourselves, we should know what its premonitory symptoms are. So, when pregnant woman dystocia, what can have augural symptom? Now let's talk about it.

What symptom does dystocia have?

Pelvic entrance stenosis is often due to cephalopelvic disproportion, fetal head is not easy to enter the basin, resulting in abnormal fetal position, such as hip exposure, shoulder exposure, middle pelvic stenosis affecting the rotation of fetal head into the basin, resulting in persistent occipital transverse position, occipital posterior position, etc.

Under normal circumstances, some primiparas should put the fetal head into the basin two weeks before the expected delivery. If the fetal head has not yet entered the basin, the relationship between the head and the basin should be fully estimated. The specific methods for checking whether the head and basin are appropriate are as follows: the pregnant woman empties the bladder, lies on her back, straightens her legs, puts her hand above the pubic symphysis, and pushes the floating fetal head toward the pelvic cavity, If the fetal head is lower than the level of pubic symphysis, it means that the fetal head can enter the basin, and the head basin is proportional, which is called negative trans stigma sign; If the fetal head and the pubic symphysis are in the same plane, it means that the head basin is not symmetrical, which is called the trans stigma sign, which is suspicious positive; If the fetal head is higher than the plane of pubic symphysis, it means that the cephalopelvic is obviously disproportion, which is called positive trans stigma sign (Fig. 1). For pregnant women with positive trans stigma sign, they should take the flexion half decubitus position of their legs, and check the trans stigma sign of fetal head again. If it turns negative, it indicates that the pelvic inclination is abnormal, not the cephalopelvic disproportion.

If the lateral measurement of the pelvis is abnormal, the measurement should be carried out in the pelvis. The diagonal diameter is less than 11.5cm. The protrusion of sacral promontory is the narrow entrance plane of the pelvis, which belongs to the flat pelvis. The narrow middle pelvic plane and the narrow exit plane of the pelvis often exist at the same time. The anterior curvature of the sacrum, the diameter between the ischial spines and the width of the ischial notch (i.e. the width of the sacrospinal ligament) should be measured. If the diameter between the ischial spines is less than 10cm, the width of the ischial notch, If the diameter between the ischial tubercles is less than 8 cm, the posterior sagittal diameter of the outlet should be measured and the sacrococcygeal joint range of motion should be checked to estimate the degree of stenosis of the pelvic outlet plane. If the sum of the diameter between the ischial tubercles and the posterior sagittal diameter of the outlet is less than 15 cm, it is the pelvic outlet plane stenosis.

matters needing attention

In late pregnancy, the fetus grows more rapidly. In addition, in late pregnancy, pregnant women have to reserve enough energy for delivery and lactation. In this period, in addition to ensuring the supplement of protein, vitamins, sugar and other nutrients, we should also pay attention to increasing the supplement of iron, calcium, zinc and other trace elements. Pregnant women in this period should pay attention to eat more pig liver, fish, meat, egg yolk, kelp, laver, dried shrimp, black fungus, dried tofu, peanuts and other food.
