In the 5th month of pregnancy, termination of pregnancy is usually performed by transabdominal amniotic cavity injection of Levanox to induce abortion. If you consider carefully and decide to abort the pregnancy, it is recommended to go to a local public regular hospital for ultrasound examination, routine white belt examination, electrocardiogram, routine blood test, clotting time test and liver and kidney function tests. If there are no contraindications to induced abortion, hospitalization will be admitted to induce abortion. After hospitalization, Levanox 100mg will be injected into the transabdominal amniotic cavity. Generally, effective contractions will be initiated within 3 days, and the fetal placenta will be expelled from the body, but sometimes there will be some fetal membranes and placenta left, and if there is residue, the hospitalization will be about 5 days for the clearance operation. After the operation, rest for half a month, forbid sex for 1 month, and review ultrasound 10 days after the operation to understand the recovery of the uterine cavity.
