Symptoms of Yorkshire dystocia

summary

The so-called dystocia is that the fetus can not be delivered smoothly. Whether the delivery can be carried out normally depends on the following factors. Any one or more of the three factors, including productivity, birth canal and fetal condition, will hinder the process of delivery and cause dystocia. So, how to prevent dystocia? Dystocia is also the result that every pregnant woman does not want to see, but we need to know some knowledge, so that when symptoms appear, timely measures can be taken. The following is the answer to "" and hope to help you.

Symptoms of Yorkshire dystocia

Many women have small bones, so the pelvis is not wide enough during childbirth. Because of the narrow pelvis, which affects the fetal position. The pelvis is an important factor to consider when estimating the difficulty of delivery. During pregnancy, we should find out if there is abnormality in pelvis and cephalopelvic disproportion, and make early diagnosis to determine the appropriate mode of delivery.

Ask the pregnant woman if she has rickets, poliomyelitis, tuberculosis of spine and hip joint and history of trauma in her childhood. If she is a multipara, she should know whether she has a history of dystocia and its causes, and whether the newborn has birth trauma.

If the height of pregnant women is less than 145cm, they should be alert to small pelvis, and pay attention to the body shape, gait, spine and hip deformity, symmetry of Mie's rhombic fossa, pointed abdomen and overhanging abdomen of pregnant women.

matters needing attention

Estimation of cephalopelvic relationship: under normal circumstances, some primiparas should put the fetal head into the basin 2 weeks before the due date of delivery. If the fetal head has not yet entered the basin, the cephalopelvic relationship should be fully estimated. The specific methods for checking whether the cephalopelvic relationship is appropriate are as follows: the pregnant woman empties the bladder, lies on her back, straightens her legs, and the examiner puts her hand above the pubic symphysis, 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 matched, 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.
