Whether or not pelvic effusion requires infusion cannot be generalized, and the nature of pelvic effusion needs to be clarified. If it is physiological pelvic effusion, it can be treated without infusion, if it is pathological pelvic effusion, it can be actively treated by intravenous infusion: 1. physiological pelvic effusion: physiological pelvic effusion is formed after follicle rupture during ovulation and flows into the pelvis, or after menstruation, due to the reflux of menstrual blood, causing the pelvis not yet fully absorbed, there will also be effusion, usually the depth of the effusion does not exceed 2 cm. for these For pelvic effusion caused by these two conditions, no treatment can be taken, and it usually subsides automatically in about 3 days, which does not affect the health and does not need to be infused. 2. Pathological pelvic effusion: For example, pelvic effusion caused by chronic pelvic inflammatory disease can be eliminated by intravenous infusion at the arrival of menstruation or during non-menstruation, but there is a time limit, try to infuse for about 5 days and should not exceed 7 days. This is because prolonged use of antibiotics can cause dysbiosis of the vaginal flora environment and may lead to mycosis fungoides. In addition to intravenous infusion, oral medication, as well as herbal collapse therapy and radiofrequency electrotherapy can be used to achieve the purpose of treating pelvic inflammatory disease. For pelvic effusion caused by ruptured corpus luteum or ruptured ectopic pregnancy, timely surgical treatment is recommended.
