Overview: including the production of uterine contraction of the diaphragm and abdominal muscle contraction and the anal to muscle contraction, with the main uterine contraction. In the course of delivery, uterine contraction of rhythm, symmetry and polarity is not normal or intensity, frequency change, known as abnormal uterine contraction. Clinical more because of production factors, fetal abnormality or obstruction of a difficult birth, the fetus through the birth canal resistance increased, resulting in secondary production of abnormal. Abnormal contraction of the uterus into the uterine contraction weak and the strong uterine contraction two categories, each category and for the coordination of the uterine contraction and uncoordinated contraction of the uterus.
Treatment measures: coordination of uterine contraction too radical a maternal history of the middle class in pre-production phase one to two weeks before it is not appropriate on leave, so as to avoid accidents, conditions should be hospitalized early production. Labor after the enema it is not appropriate. Jiechan ahead and rescue neonatal asphyxia preparation. When the fetus delivered not » to coordinate a strong contraction of the uterus uterine contraction of rhythm, symmetry and polarity are normal, only a strong contraction of the uterus, the frequency. If the birth canal without resistance, cervical rapidly in a short time the entire opening, the end of maternity leave in a short period of time, the birth process less than three hours, known as the radical middle. The maternal. The mother and infant the impact of the mother: the too frequent contractions, the birth process too fast and could be the beginning of maternal cervix, vagina and perineum laceration. Jiechan when there was no time to be disinfected to puerperal infection. Postpartum uterine muscle fibers shrink-prone bad placenta stranded or postpartum hemorrhage. of fetal and neonatal effects: a strong contractions affect the frequency of uterine placental blood circulation, the fetus in the womb hypoxia, high incidence of fetal distress, neonatal asphyxia or even death. Fetus delivered too fast and fetal head in the middle, the pressure on the lifting of a sudden, to newborns with intracranial hemorrhage. There was no time to Jiechan, newborn vulnerable to infection. Ifcan cause fractures, traumatic.
uncoordinated contraction of the uterus too 1. Ankylosing uterine contraction ankylosing uterine contraction is not the function of abnormal uterine muscle tissue, almost all of the unusual external factors, such as labor after the birth occurred because of obstruction, or inappropriate use of Oxytocin, or placental abruption blood infiltration myometrium, in the mouth can cause cervical over part of the myometrium in ankylosing spastic contraction. Maternal irritability, persistent abdominal pain, according to resist. Abnormal Fetal Position touch unclear, fetal heart rate Ting Buqing. Sometimes there can be pathological shrink-Central, hematuria, and other sign of uterine rupture signs. 2. Uterine cramps and narrow Central a unit of the uterus wall muscle spasm was uncoordinated contraction of the ring formed by narrow, continuing to relax, known as uterine cramps and narrow ring. And more from top to bottom in the womb of the junction, but also in the carcass of a narrow Ministry to fetal neck, the common fetal lumbar . a narrow ring around the fetal neck Central prone to narrow the location map of a narrow ring of uterine cramps and more tense because of the spirit, Guodupilao and inappropriate use of contractions or rude conduct of obstetric caused by handling. Maternal persistent abdominal pain, irritability, cervical expansion slow, fetal presentation of the decline in stagnation, when the fast, slow fetal heart rate. Vaginal examination reach a narrow ring, this ring is characterized not as contractions increased, and pathological shrink-ring different.
