Before patients are enrolled in this clinical study, the researchers will do a detailed screening of the subjects based on the inclusion criteria and the exclusion criteria to determine if the patients are appropriate for the clinical study. Patients who meet the conditions of the study will be required to sign an informed consent form. Then they will be randomly assigned to the experimental group or the control group. To evaluate the primary outcome measures and secondary outcome measures and to observe the incidence of organ and vascular injury.
