Introduction
After surgery, pathogens such as bacteria and fungi can cause an increase in body temperature. Aseptic necrotic substances resulting from localized tissue cell necrosis and protein breakdown may be absorbed, potentially triggering aseptic inflammation and leading to postoperative fever. Patients with hyperthyroidism who have not been adequately prepared before surgery may also develop fever symptoms.
Fever is clinically referred to as pyrexia. It is common for patients to experience fever following surgery. Causes of postoperative fever include surgical site infections, absorption of tissue debris, endocrine dysfunction, and others.
1. Postoperative Infection
Pathogens such as bacteria, fungi, viruses, mycoplasma, and chlamydia can all lead to elevated body temperature. Additionally, a patient's physical condition often weakens after surgery, making them more susceptible to upper respiratory tract infections, pulmonary infections, and other conditions that may result in fever. Physical cooling methods such as ice packs can be used, and medications like ampicillin or amoxicillin may also be taken to alleviate symptoms.
2. Absorption of Tissue Debris
After surgery, the absorption of sterile necrotic materials produced by localized tissue cell necrosis and protein breakdown may trigger aseptic inflammation, leading to an increase in postoperative body temperature. Antibiotic medications may be prescribed under medical supervision for treatment.
3. Endocrine Dysfunction
In patients with hyperthyroidism, inadequate preoperative preparation may lead to a postoperative thyroid storm, which can cause fever. Fever-reducing patches can be used to help relieve the symptoms.
In addition, postoperative dehydration may also lead to fever.
