Whether abortion can be performed for pelvic effusion depends on the amount of pelvic effusion. If the pelvic fluid is a small amount, below 2cm, it will not affect the abortion procedure; routine anti-inflammation should be performed for 3-5 days after the abortion procedure to avoid increasing the chance of infection due to the surgical operation. If the pelvic fluid is already very large, at 3cm, 4cm and above, it is recommended to consider 3 days of anti-inflammatory before performing abortion. The abortion should be performed for 3 days after the abortion to avoid the risk of infection due to the surgical operation or the blood from the uterine cavity entering the pelvic cavity and causing the fluid to become more. Also try to review 3-5 days after menstruation. If fluid still persists, make sure to take oral medication regularly according to the doctor’s prescription to treat the pelvic fluid to avoid inflammation of the fallopian tubes.
