If there is fluid in the uterine cavity after removal of the uterus, it is recommended to exclude whether it is oozing fluid caused by inflammation or due to the accumulation of blood in the uterine cavity caused by poor uterine regeneration. If it is due to poor uterine regeneration, it is recommended to give intramuscular injection of oxytocin to promote uterine contraction and discharge of blood, at the same time, you can take oral maternal health granules, which can also promote uterine contraction and discharge of blood, which can quickly make the uterine cavity discharge fluid. If the fluid in the uterine cavity is caused by inflammation and exudation, clinically the most important thing is to actively give anti-inflammatory treatment, such as oral broad-spectrum antibiotics, combined with the treatment of anaerobic bacteria tinidazole, for five consecutive days, and then review the ultrasound, or gynecological examination to understand whether the inflammation has been significantly improved, and the inflammation is controlled before the use of medicines to promote uterine contraction for treatment.
