How long does fever usually last after heart bypass surgery

Jan 08,2025

The duration of fever after heart bypass surgery generally varies from individual to individual, but can usually be summarized according to the following situations:

1. Mild fever: Postoperative mild fever caused by surgical stress and trauma, with a body temperature generally below 38 ℃. This fever usually lasts for a short time, about 3 days. This type of fever is generally a normal postoperative reaction, clinically referred to as heat absorption, and does not require special treatment, but should be closely monitored for changes in body temperature.

2. Moderate to high fever: If the postoperative body temperature continues to exceed 38 ℃ or the fever lasts for more than 3 days, this may be caused by factors such as infection. At this time, it is necessary to closely monitor the patient's symptom changes, such as whether the blood count is elevated, whether there is lung infection or wound infection, etc. Determine the presence of infection through examination methods such as filming and blood tests. If an infection occurs, the duration of fever may be prolonged and treatment for the infection may be necessary, including infusion of anti-inflammatory drugs, local treatment of the wound, etc.

3. Special circumstances: Some patients may experience reactive pleural effusion after surgery, and there may also be low-grade fever during the process of fluid absorption, but this usually occurs within one week after surgery and the body temperature is not too high. If the fever persists or the body temperature is too high, timely medical examination and treatment should be sought.

The duration of fever after heart bypass surgery varies among individuals, but generally mild fever lasts for about 3 days, while fever caused by factors such as infection may last longer. During the postoperative recovery period, patients should closely monitor changes in body temperature and other symptoms. If there are any abnormalities, they should seek medical attention promptly for examination and follow the doctor's guidance for treatment.
