For patients with brainstem hemorrhage, it is common to develop high fever after the bleeding, where the body temperature often exceeds 38.5℃. There are many reasons for the occurrence of high fever. It can be considered that the presence of an intracerebral hematoma compresses the hypothalamic temperature set point, causing abnormalities in the set point function and leading to central fever, with temperatures often reaching 39℃ or even higher than 40℃. At this time, the use of antipyretic drugs alone generally has poor therapeutic effect. It often requires the effective absorption of the intracerebral hematoma for the body temperature to gradually return to normal. Another situation, considering the occurrence of pulmonary infection, it is necessary to promptly provide patients with antibiotics for effective treatment. When the pulmonary infection is effectively controlled, the body temperature will also gradually decrease.
