Infusion reactions occur most often when the infusion speed is relatively fast or the input fluid contains pyrogenic sources or impurities, which cause patients to suddenly develop symptoms of infusion reactions such as chills, high fever, pallor, and cold sweats. In these cases, the infusion should be stopped immediately and replaced by 0.9% saline intravenously. At the same time, glucocorticoids such as dexamethasone and prednisolone can be injected intravenously, which have anti-inflammatory, anti-allergic and anti-shock effects. In case of high fever, antipyretic drugs can be given, commonly used are acetaminophen, ibuprofen, lysergic acid, etc. At the same time, the patient needs to be sedated, given oxygen, cardiac monitoring, and closely observed vital signs.
