Nursing points included using critical thinking to accurately triage and opening a green channel for critically ill patients，predictive nursing including indwelling high- pressure resistant venous catheter in advance and collecting blood samples，breaking the routine to control blood pressure individually，sufficient analgesia and psychological care. After accurate triage and effective treatment in the emergency department，the patient was safely transferred to the ward.
