Chronic pelvic inflammatory disease is a common gynecological disease, which refers to the chronic inflammation of the female internal genitalia and its surrounding connective tissue, pelvic peritoneum. Its main clinical manifestations are menstrual disorders, increased leucorrhea, lumbar and abdominal pain and infertility, etc. If chronic adnexitis develops, a lump may be palpable. Chronic pelvic inflammatory disease sometimes has systemic symptoms of low fever and easy fatigue, and some patients have symptoms of neurological weakness such as insomnia and mental discomfort due to the long duration of the disease. Recurrent attacks of chronic inflammation can also lead to menstrual disorders and infertility, which seriously affect the physical and mental health of women. The clinical use of conventional drugs such as levofloxacin and metronidazole for the treatment of chronic pelvic inflammatory disease, but the drug is difficult to enter the lesion, the treatment effect is not good. Moreover, the repeated use of antibiotics is prone to drug resistance, secondary infection, and dysbiosis, which cannot achieve satisfactory results. The clinical research study observed the efficacy of combined physical factor treatment for chronic pelvic inflammatory disease in 60 cases and found that physical factor treatment has good efficacy. The ultrashort wave of physical factor therapy improves local blood circulation and tissue nutrition, enhances the function of reticuloendothelial system, improves immunity and inhibits bacterial growth and reproduction through obvious warm and non-thermal effects, thus promoting the absorption of inflammation exudation and inhibiting the spread of lesions to achieve therapeutic effects. DC ion introduction method applies iodine as the cathode to introduce iodine ions into the inflammation site, forming ion mounds in the skin and gradually absorbing into the blood, softening scars, loosening adhesions and promoting inflammation absorption; compound salvia injection as the anode, causing small blood vessels to dilate, improving blood circulation, promoting material metabolism and improving local tissue nutrition. The drug concentration in local tissues by DC ion introduction method is 20 to 100 times higher than that by intramuscular injection, and the action time is long, which can play a good role in controlling inflammation.
