When there is hemorrhage at 15 weeks of pregnancy, ultrasound suggests that there is a large hematoma but the development of the fetus is normal, it is necessary to actively preserve the fetus, but if the fetus is dead in the uterus, it is necessary to terminate the pregnancy in a timely manner. 15 weeks pregnant with hemorrhage, ultrasound suggests that there is a large hematoma, most often lead to adverse pregnancy outcomes, when the ultrasound suggests that the fetal development is good, can follow the doctor’s instructions to give blood coagulation enzyme to stop bleeding, penicillin and other preventive measures to prevent infection, progesterone and other drugs to protect the fetus treatment, if the symptoms do not ease or aggravate, need to terminate the pregnancy in a timely manner. When the ultrasound suggests that the fetus is dead in the uterus, it is necessary to actively prepare blood and open the venous access, by a professional physician to terminate the pregnancy by clamping, during the operation to avoid damage to the uterus, and after the operation to pay attention to the promotion of uterine contraction of the uterus such as hysteronin and other drugs, penicillin and other medications to prevent infection, to observe the situation of the vaginal bleeding, prohibit the pelvic bathing and sexual intercourse for one month, and comply with the doctor’s orders to review on time. The first time I saw a hematoma in my 15 weeks of pregnancy, the ultrasound indicated that there was a large hematoma that needed to be actively dealt with in a timely manner under the guidance of the doctor.
