1, in the examination of functional blood, the most important is blood routine and ultrasound, not sex hormone examination! 2, in the medication for the treatment of dysfunctional blood, the most important and most neglected is progesterone injection, which is natural, very cheap, has a good hemostatic effect, and is most suitable for those dysfunctional blood patients who are not anemic. Because the withdrawal of blood may be more after stopping the drug, if the endothelium is thick, the use can be added at the same time with propecia 25mgx3d, in order to reduce the withdrawal of blood. 3, the use of high-dose short-acting oral contraceptives, more suitable for those anemic patients with dysgerminosis, the use of the dose should be gradually reduced, there is a longer period of time to maintain the amount. This longer period of time is to be used to correct the patient’s anemia, so during this period of time, the patient should be given effective iron supplements to supplement blood, and strive to correct the anemia in a menstrual cycle, before stopping the pill withdrawal. 4, patients with dysfunctional hemorrhage are not deficient in estrogen! Endothelial growth method as a treatment method, due to the lack of a clinically effective estrogen preparation (such as, 250mg of combined estrogen injection, or estradiol benzoate injection) to stop the bleeding effect is not ideal. Therefore, the current endothelial detachment method and endothelial atrophy method is more clinically practical significance! 5, scraping is never the first choice for the treatment of functional hemorrhage! Unless endometrial lesions are suspected to be the need for diagnostic scraping, clinically it is also common that scraping does not stop the bleeding well, so the first choice should also be drug therapy. 6, must be carried out to each patient with dysmenorrhea “dysmenorrhea education”: a, progesterone injection during the medication bleeding will be significantly reduced, or will stop. (It is normal that the bleeding does not stop completely!) b. There will be a heavy bleeding (withdrawal) soon after stopping the medication. Don’t worry, the bleeding will stop within 7-10 days. If the withdrawal of blood lasts more than ten days, it is an indication for diagnostic curettage! c. There may be 2-3 days with a lot of blood withdrawal, you can use hemostatic drugs (e.g., Tocopherol) to reduce the amount of blood, it is not necessary to stop the bleeding completely, the bleeding can be reduced. d, this hemostatic treatment must be followed by at least 3-6 months of the second half of the cycle of Amnion Progesterone (6mgx10d/month) to adjust the cycle of treatment!!!! e. Even if menstruation becomes regular for a period of time after treatment (usually not more than a year), it may still recur in the future, and it is most important to maintain a normal amount of menstruation at least once every two months. 1, with progesterone withdrawal withdrawal of blood can wait up to 3 weeks. 2.If there is no withdrawal of blood in 3 weeks after stopping the medication, then after excluding pregnancy, you can try artificial cycle once, if there is withdrawal of blood, it suggests that low estrogen amenorrhea. 3, low estrogen amenorrhea except hyperprolactinemia (HPRL), drug treatment are artificial cycle, if you intend to further diagnose the cause of amenorrhea (to exclude HPRL), should be discontinued after a month of all hormone drugs, measurement of sex hormone levels. 4, do not blindly believe in auxiliary examination, the biggest significance of BUS, in fact, is to rule out the organic lesions that cause bleeding. The use of short-acting contraceptives to stop bleeding (commonly used MaFuLong, cheap) is more suitable for patients with more severe anemia, the main purpose is still progesterone effect is mainly, at the same time, there is a longer reduction in the amount of maintenance time used to carry out effective blood replenishment therapy. The starting dose of 2 tablets / 12 hours is enough to completely stop bleeding in three days, and then the same amount of maintenance for another three days, and then reduce the dose to 1 tablet / 8 hours, three days later, then reduced to 1 tablet / 12 hours, do not need to be reduced again, and maintain until the anemia is corrected after the discontinuation of withdrawal of blood (withdrawal of blood, the patient will have a more pronounced abdominal pain, which is normal).
