[Outlined]
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 uterine contraction of the uterine contraction weak and divided into uterine contraction too two categories, each category and for the coordination of the uterine contraction and uncoordinated contraction of the uterus.
[Treatment]
to coordinate a strong contraction of the uterus
A maternal history of the radical middle, in pre-production period of 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 of neonatal asphyxia and rescue preparations. Wu Shi maternal fetal delivered at the downward breath. If there was no time to disinfect and radical middlenewborn, neonatal intramuscular injection of vitamin K1 should be the prevention of intracranial hemorrhage, and as soon as possible tetanus anti-toxin injection refining 1500 U. Postpartum careful examination of cervical, vaginal, vulvar, if it has torn the timely closure. If it is not the Jiechan disinfection should be given antibiotics to prevent infection.
uncoordinated contraction of the uterus too
1, ankylosing a uterine contraction when diagnosed with ankylosing uterus to contract, should be timely to give contractions inhibitors, such as 25% of magnesium sulfate 20 ml 5% glucose 20 ml slow intravenous injection, 1 mg epinephrine or 5% glucose vein 250 ml Drip. If it is the obstruction of reasons, should immediately visit Cesarean section. If the intrauterine fetal death can be inhaled ether anesthesia. Following the above address, if still unable to lift ankylosing uterine contraction, consideration should be given to Cesarean section.
2, narrow ring of uterine cramps should seriously look for uterine cramps lead to a narrow ring of the reasons, to give time to correct. Stop all stimulation, such as the prohibition of vaginal operation, disabled, such as oxytocin. If there are no signs of fetal distress, can be given tranquilizers such as morphine or meperidine, the general will remove abnormal contractions. When uterine contraction back to normal, vaginal delivery or feasible for natural delivery. If the above address, uterine cramps and narrow ring can not be alleviated, I did not open the whole Palace, the Ministry of fetal presentation, or with signs of fetal distress, should immediately visit Cesarean section. If intrauterine fetal death, I have a whole Palace feasible ether anesthesia, as vaginal delivery.
[Clinical]
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.
Impact on 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 invasion of uterine blood Muscle, can cause cervical part of the mouth over 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 sign of uterine rupture, and other 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, waist, fetal common.
More tense because of the spirit, Guoduopilao and inappropriate use of contractions or rude manner by the obstetric treatment. 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.
