Pelvic inflammatory disease, medically known as pelvic inflammatory disease, is a group of infectious diseases of the upper female genital tract, some very mild and some very severe. In severe cases, there is persistent lower abdominal pain (aggravated by activity or sexual intercourse), fever or even hyperthermia, chills, headache, and lack of appetite. In severe cases, the disease is acute, with elevated body temperature, increased heart rate, pressure, rebound pain and muscle tension in the lower abdomen, and even abdominal distention, with disappearance or weakening of bowel sounds. The onset of menstruation is characterized by increased menstrual flow and prolonged periods. If the peritoneum is involved, nausea and vomiting, abdominal distension and diarrhea may be associated. Involvement of the urinary system may be accompanied by urinary frequency, urinary urgency, and urinary pain. If an abscess is formed, the mass may compress the bladder and cause difficulty in urination and frequent urination, and if the mass is located outside the peritoneum, diarrhea, urgency and difficulty in defecation may occur. In mild cases, pelvic inflammatory disease can be treated with oral or intramuscular antibiotics on an outpatient basis, while in severe cases, a comprehensive treatment with IV antibiotics is required, such as pelvic peritonitis, tubo-ovarian abscess, and pelvic abscess. Supportive therapy such as semi-recumbent rest, high-calorie, high-protein, high-vitamin liquid diet, correction of electrolyte and fluid balance, etc. is also given. For tubo-ovarian abscesses or pelvic abscesses that are not satisfactorily treated with antibiotics: if the symptoms do not improve and worsen in 48-72 hours after antibiotic treatment, timely surgery should be performed to avoid rupture; if the condition improves after antibiotic treatment and the mass does not disappear after 2-3 weeks of continued medication and has been confined, surgical excision should be performed to avoid future acute attacks; if the abscess ruptures, emergency surgery should be performed and antibiotic treatment should be given at the same time, and if it is not diagnosed and treated in time, the The mortality rate is high.
