If excessive sweating occurs after infusion, it cannot be ruled out that the speed of infusion is too fast, which may lead to cardiac insufficiency or increase the burden on the heart, resulting in sweating, weakness, chest tightness and, in severe cases, pulmonary edema, especially in patients with underlying diseases and chronic heart and lung diseases. It is also necessary to observe the reaction to the infusion, because some patients are prone to sweating and even chest tightness and peripheral rash, and in severe cases, shivering and other symptoms. It is important to monitor the heart rate and blood pressure during the infusion, and especially to choose the infusion treatment carefully. For some diseases that can be treated orally, infusion should not be chosen as much as possible, because infusion can have many side effects.
