The first is the psychological aspect, which relieves patients' anxiety and tension. Relax and keep a good attitude. The patient is required to inform the nurse on duty (or the responsible nurse) at the first time what discomfort symptoms appear during infusion, so as to deal with them in time. Secondly, according to the medication situation, introduce the situations and precautions that are easy to appear in the infusion process to patients. For example, antibiotics and drugs, especially cephalosporins, are forbidden to drink alcohol and so on. In addition, pay attention to rest when infusion, so as to avoid fatigue aggravating the condition.
