The main causes of acute pelvic inflammatory disease are: 1. postpartum or post-abortion infection: after childbirth, the maternal physique is weak, the cervical opening is not closed in time due to residual blood and fluid outflow, there is a placental abscission surface in the uterine cavity, or the birth canal is damaged, or there is a placenta or fetal membrane residue, or there is premature sexual intercourse after childbirth, pathogens invade the uterine cavity, easily causing infection; natural abortion, drug abortion process vaginal bleeding time, or tissue residue in the uterine cavity, or abortion surgery is not strict. Infection after abortion can occur after spontaneous abortion, drug abortion, or tissue residue in the uterine cavity, or aseptic operation of abortion surgery is not strict. 2. Infection after intrauterine surgical operation: such as placement or removal of intrauterine device, curettage, tubal lavage, hysterosalpingography, hysteroscopy, submucosal fibroid removal, etc., due to preoperative sex or surgical sterilization or improper selection of preoperative indications, the original chronic inflammation of the reproductive tract is disturbed by surgery and causes acute attack and spread; some patients do not pay attention to personal hygiene after surgery, or do not comply with the postoperative procedures. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. The actual fact is that you will be able to get a lot more than just a few of the most popular and popular items. 4, the direct spread of inflammation of adjacent organs: most commonly, when appendicitis, peritonitis, because they are adjacent to the female internal genital organs, inflammation can be caused by the direct spread of pelvic inflammation; with chronic cervicitis, inflammation can also be through the lymphatic circulation, causing pelvic connective tissue inflammation. 5. Acute attacks of chronic pelvic inflammatory disease, etc. The symptoms of acute pelvic inflammatory disease are characterized by the urgency of the disease, the severity of the disease, lower abdominal pain, fever, chills, headache, loss of appetite. On examination, the patient is found to be acutely ill with high body temperature, rapid heart rate, muscle tension, pressure pain and rebound pain in the lower abdomen. Pelvic examination: large amount of purulent vaginal discharge, obvious tenderness in the fornix, pressure pain and rebound pain in the uterus and both adnexa, or thickening of one adnexa. 1.Initiation of lower abdominal pain with fever and chills. 2.If accompanied by peritonitis, there is nausea, vomiting, abdominal distension and diarrhea. 3.If there is abscess formation, there may be lower abdominal mass and local pressure irritation symptoms, such as bladder irritation symptoms and rectal irritation symptoms. 4.The patient has an acute appearance with high body temperature, rapid heart rate, abdominal distension, lower abdominal muscle tension, pressure pain and rebound pain. 5. Pelvic examination: vaginal congestion, burning, large amount of purulent discharge; posterior fornix tenderness, cervical lifting pain; uterus slightly large and soft, pressure pain, activity limitation; thickening of the adnexal area, pressure pain, mass. Treatment】 1. General supportive therapy: bed rest, semi-recumbent position; nutritious and easily digestible diet; small amount of blood transfusion for anemia; analgesics for heavy pain. 2.Antibiotic treatment to control infection: use powerful and large amount of antibiotics, commonly used cephalosporin, ampicillin, metronidazole and other intravenous drip 3.Surgical treatment: when intrauterine tissue residue is suspected, clean the uterus after controlling infection. If an abscess is formed and the body temperature continues to drop after 48-72 hours of drug treatment, and the toxic symptoms worsen or the mass increases, perform abscess incision and drainage; if the tubal abscess or tubo-ovarian abscess improves after drug treatment, continue to control the inflammation for several days and then perform surgery; if abdominal pain suddenly increases, high fever, chills, nausea, vomiting, abdominal distension, refusal to press or toxic shock is suspected, perform surgery immediately. If abscess rupture is suspected, abdominal dissection should be performed immediately. The principle of drug use] is reasonable to choose antibiotics according to the drug sensitivity test, before the laboratory results, if the condition is not too serious, you can choose penicillin, streptomycin; if the condition is serious, you need to choose broad-spectrum antibiotics, combined with good efficacy, the combination must be reasonable, less drug types, less toxicity, after the results of bacterial culture, can be replaced according to the situation. The route of administration is intravenous drip with fast results. The application of antibiotics requires a sufficient amount, and attention must be paid to toxic reactions. For light acute pelvic inflammatory disease, intravenous injection of cyanase, bupropion or metronidazole is the mainstay; for heavy acute pelvic inflammatory disease, a combination of two or more antibacterial agents is appropriate. 3, abscess formation, drug treatment is not satisfactory, perform abscess incision and drainage, take pus for bacterial culture and drug sensitivity test, choose strong, effective antibiotics.
