Cerebral infarction itself generally does not have a fever, but individual cases can occur, as follows: 1, if it is a large cerebral infarction or when the superior brainstem, it also occurs central hyperthermia. This kind of fever is generally antipyretic and analgesic drugs are useless, the most useful way is physical cooling; 2, another way of fever may be the patient because of the occurrence of cerebral infarction, misinhalation and choking, which leads to lung infection. This way needs to do sputum culture in time, suck out the misaspirated material in time, do bacterial culture, and apply appropriate antibiotics according to the drug sensitivity, and at the same time, strengthen the nursing measures such as turning, patting the back, and suctioning; 3, a common site of infection may be the urinary infection, and the more serious patients will be bedridden, which will lead to nursing or personal hygiene problems, and urinary infections may occur; 4, uncommonly, the bloodstream infection, such as Bacteremia is a more serious infection, and adequate blood cultures should be done. Adjust the appropriate antibiotic according to the sensitivity. Patients with cerebral infarction can develop lingual-pharyngeal vagus nerve damage, which can lead to difficulty in drinking, swallowing and choking, and even aspiration. In this case, patients are often advised to insert a nasal feeding tube, so that water, drugs and food can reach the stomach directly through the nasal feeding tube to avoid aspiration and choking. However, individuals often do not quite understand this way of operation, in fact, in neurology or critical care medicine, are very common a way of operation, we do not have to worry.
