How does pelvic stricture do?
summary
To determine the type and degree of pelvic stenosis, and many people have already understood its basic treatment methods, such as fetal position, fetal size, fetal heart rate, strength of uterine contraction, degree of uterine dilatation, rupture of membranes or not, combined with age, labor times and previous delivery history to make a comprehensive judgment and determine the mode of delivery. In order to avoid this situation, let's talk about the pelvic stenosis? Let's take a look at the following.
How does pelvic stricture do?
First, the general treatment in the process of childbirth, should eliminate maternal fear, enhance confidence; Ensure the intake of nutrition and water, and supplement fluid when necessary. The pregnant women should rest more, monitor the strength of uterine contraction, listen to the fetal heart rate frequently, check the decline of fetal presentation and the degree of dilatation of uterine orifice, and pay close attention to the progress of labor.
2. The treatment of pelvic entrance plane stenosis 1. The treatment of absolute pelvic stenosis: the outer diameter of sacral and pelvic entrance is less than 16.5cm, the anteroposterior diameter of pelvic entrance is less than 8.0cm, the fetal head span sign is positive, the full-term live fetus can not be delivered through vagina, so cesarean section should be performed. 2. The treatment of relative pelvic stenosis: the outer diameter of sacroscopic region is 16.5-17.5cm, the anteroposterior diameter of pelvic entrance is 8.5-9.5cm, the fetal head trans stigma sign is suspiciously positive, and the weight of full-term live fetus. 3. The treatment of critical pelvic stenosis: most of them can be delivered through vagina.
Third: the treatment of middle pelvis and pelvic outlet plane stenosis. During delivery, the fetus completes flexion and internal rotation in the middle pelvic plane. If the middle pelvic plane is narrow, the fetal head flexion and internal rotation are blocked, and persistent occipital transverse or occipital posterior position is easy to occur. If the cervix is fully opened and the biparietal diameter of fetal head is below the level of ischial spine, manipulation or fetal head suction device can be used to correct the position of fetal head, and then fetal head suction or forceps can be performed. If the biparietal diameter of the fetal head is above the ischial spine level, or fetal distress signs appear, the trial production should be stopped and cesarean section should be performed to end the delivery.
matters needing attention
It should be analyzed according to the type of deformity pelvis, the degree of stenosis, the size of fetus and the productivity. If the deformity is serious, obvious cephalopelvic disproportion, cesarean section should be performed in time.
