Surgical damage, absorption of necrotic tissue, or toxin stimulation can cause body temperature to be 37.5~37.8°C; in addition, incomplete bowel cleansing before surgery can cause the contents of the intestines to flow out and contaminate the wound surface, which can also cause fever; there are more bacteria in the anus. Incisions, punctures, and any other damage that destroys the skin barrier can enter tissues and cause infection, and most of the wounds after anorectal surgery are open, so the wounds after the operation are very susceptible to infection and fever. The former generally do not need to be dealt with, and the latter two must be treated in time with anti-infection, wound drainage, dressing change and other treatment measures.
① Drug reaction. Such as application of Kuzhisan or local injection of Kuzhiye, etc., can easily cause drug-induced body temperature rise, but it is generally around 38 ℃.
② After local incision infection or perianal abscess, the purulent secretions are not cleaned up, which causes the absorption of toxins into the blood and increases the body temperature.
③ Elevated body temperature caused by other complications, especially the elderly due to weak physique, are prone to respiratory infections and urinary system infections.
① Fever caused by drug reaction is generally unnecessary to deal with. After the drug is slowly absorbed, the body temperature will gradually return to normal. If the body temperature is at 38℃ for a long time, antipyretic and analgesic drugs or antipyretic, detoxifying and dampening drugs can be taken orally.
②Fever caused by local wound infection should take metronidazole or do bacterial culture to find the most sensitive antibiotic treatment. If there is an abscess formed locally, cut and drain the pus in time to keep the wound drainage smooth.
③Fever caused by other complications after surgery, such as respiratory tract infection, urinary system infection, etc., can be treated at the same time for other diseases based on the treatment of anorectal diseases.
