Intermittent brown discharge in early pregnancy may be due to bleeding cervical polyps, pre-eclampsia, ectopic pregnancy and embryonic abortion, which requires prompt consultation with the obstetrics department to clarify the cause and then targeted treatment. Common causes and treatment 1, cervical polyp bleeding: is caused by chronic inflammatory stimulation, manifested as increased leucorrhea, dripping bleeding, if repeated vaginal bleeding, need to remove the cervical polyps, so as to avoid repeated bleeding caused by intrauterine infection; 2, pre-eclampsia: manifested as mild lower abdominal pain with a small amount of vaginal bleeding, if bleeding abdominal pain further aggravated, may progress to inevitable abortion, need timely chorionic membrane The diagnosis should be made by chorionic gonadotropin (HCG) and ultrasound. According to the previous history of pregnancy and delivery and luteal function, progesterone can be supplemented as appropriate, such as oral progesterone, dydrogesterone or progesterone injection, and ultrasound should be reviewed regularly to observe the growth of fetal heart and fetal buds. 3. ectopic pregnancy: it is manifested as persistent small amount of vaginal bleeding after menopause with lower abdominal pain, and if no intrauterine gestational sac is seen in ultrasound, blood HCG should be further checked and reviewed regularly to observe the dynamic changes of HCG. If ectopic pregnancy is considered more likely, timely hospitalization is needed for observation, and conservative or surgical treatment should be decided according to clinical manifestations and HCG value; 4. embryonic abortion: there may be no abdominal pain and bleeding, or there may be a small amount of vaginal bleeding, if the intrauterine gestational sac lasts for more than two weeks without a fetal heart, or the average diameter of the intrauterine gestational sac is more than 2.5cm without a fetal heart, embryonic abortion should be considered. If embryonic abortion is diagnosed, termination of pregnancy should be given in time, and abortion or medical abortion should be given according to the size of the gestational sac and personal wishes. It is recommended that patients should rest in bed during treatment, avoid unnecessary stimulation, avoid heavy physical activities and exertion, prohibit sexual intercourse, and keep the vulva clean and hygienic.
