Too strong contraction of the uterus

Outlined productivity including uterine contractility, abdominal muscles and diaphragm contractility and the levator ani muscle contraction, with the main uterine contractility. In the delivery process, contraction of the uterus rhythm, symmetry and polarity normal or intensity, frequency change as abnormal uterine contractility. Clinical more by the middle Road or abnormal fetal form factors obstructive dystocia, fetus through the birth canal resistance, secondary to abnormal productivity. Abnormal uterine contractility clinical divided into contraction of the uterus and uterine contraction weak too strong two categories. Each category is made for coordination uncoordinated contraction of the uterus and uterine contraction. Clinical manifestations (1) coordinated contraction of the uterus too strong contraction of the uterus rhythm, symmetry and polarity are normal uterine contractility just too strong and too frequent. If the birth canal without resistance, the cervical opening so quickly, the whole, childbirth end in a short time, the total output of less than three hours. called radical production. After maternal styles. Of mothers and infants (1) the impact of the mother : uterine contractions too frequent, the birth process fast, and can induce early cervical, vaginal and perineal laceration. 60.6 hours too late to be disinfected infections. Postpartum uterine muscle fiber reduce adverse prone Minute retained placenta or postpartum hemorrhage. (2) of fetal and neonatal effects : uterine contractions too frequent uterine effects of placental blood circulation, intrauterine fetal hypoxia, high incidence of fetal distress, neonatal asphyxia or even death. Deliverying the fetus fast, and the fetal head in the birth canal with the pressure suddenly lifted, can be induced neonatal intracranial hemorrhage. Too late to 60.6 newborns vulnerable to infection. The girls fell onto the ground can be induced if the fractures, injuries. (2) disharmony contraction of the uterus too strong a. Ankylosing uterine contraction ankylosing contraction of the uterus is not uterine muscle dysfunction Chang, almost all anomalies caused by external factors, such as labor after childbirth due to obstruction, or improper use of oxytocin, or placental abruption blood myometrial invasion. can cause cervical within part of the population over there myometrium ankylosing spastic contraction. Maternal irritability, persistent abdominal pain, according to resist. Presentstions touch unclear, heard the fetal heart rate. Sometimes, there may be pathological shrinking Minute Central, hematuria, and other signs of uterine rupture threatened. 2. Uterine cramps stenosis Central (4-0 ring) uterine muscle wall unit was not spastic coordinated contraction of the ring formed by narrow, continued to relax, known as uterine cramps stenosis ring. Many of the uterus next junction, but also in the matrix of a narrow, in order to fetal neck, and fetal lumbar Department common (Figure 1). (1) a narrow ring around the fetal neck (2) Central prone to narrow the location map a uterus spastic because of the narrow ring more mental stress, fatigue and the improper application of labor agents or wantonly caused by obstetric treatment. Maternal sustained abdominal pain, irritability, dilated cervix slow fetal first disclosed Ministry declined stagnated, the fetal heart rate varies from time to time. Vaginal examinations may touch on the narrow aspect of this feature is not part with the rise of labor, and pathological shrinking Minute ring. Treatment (1) coordinated contraction of the uterus too sharp production history of the maternal, before the expected date of 1 ~ 2 weeks is not appropriate to move on. so as to avoid accidents, conditional advance hospitalized labor. After the enema is not appropriate labor. 60.6 advance neonatal asphyxia and rescue preparations. Deliverying the fetus when overburden maternal downward breath. If production could not anxious to disinfection and plunged newborn, newborn should intramuscular vitamin K1 prevention of intracranial hemorrhage, Refining and early intramuscular injection of tetanus antitoxin 1500 U. Postpartum carefully check the cervix and vagina, vulva, and if so in a timely manner should tear suture. If it is not sterilized 60.6, should be given antibiotics to prevent infection. (2) disharmony contraction of the uterus too strong a. Ankylosing contraction of the uterus when a diagnosis of ankylosing contraction of the uterus, should provide timely labor inhibitors, such as 25% magnesium sulfate 20 ml 5% to 20 ml glucose slow intravenous injection. 1 mg of epinephrine or 5% to 250 ml of glucose infusion. If an obstruction, should be immediate cesarean section. If intrauterine fetal death can be inhaled ether anesthesia. Following the above, if still not be able to lift ankylosing contraction of the uterus, should consider cesarean section. 2. Uterine spastic narrow ring should seriously seek to uterine cramps stenosis part in the timely correction. Stop all stimulation, such as a ban on operating within the vagina, such as the suspension of oxytocin. If there are no signs of fetal distress, can be given sedatives such as pethidine or morphine can typically eliminate abnormal uterine contractions. When the contraction of the uterus return to normal, vaginal delivery or feasible to wait for natural childbirth. If, after the above address, uterine cramps Central stenosis not eased Palace before the opening of the entire population, the Ministry of fetal first disclosed, or accompanied by signs of fetal distress, should be immediate cesarean section. If intrauterine fetal death, I have come Palace whole, viable ether anesthesia by vaginal delivery.
