Usually chemotherapy is effective with infusion methods of intravenous drug delivery such as transperipheral venepuncture and central venous catheterization, which need to be selected according to the patient’s specific situation and chemotherapy drugs. Chemotherapy is an effective method of using chemicals to kill tumor cells and can inhibit tumor growth. Although, there are many kinds of chemotherapy administration methods, but, at present, most of the drugs in the clinic are treated by intravenous administration, usually, the use of peripheral venous puncture through the center, central venous cannulation. The main reason is that chemotherapeutic drugs irritate blood vessels, and if peripheral vascular infusion is taken it is easy to produce phlebitis and other adverse reactions. Doctors will take into account the patient’s condition, the type of drug and the patient’s response to the drug to make a comprehensive judgment and formulate an appropriate chemotherapy program, so patients do not need to worry too much. To summarize, patients need to actively cooperate with the doctor to take appropriate treatment, so as not to delay the disease.
