First, to avoid delaying surgery operation , those who are injured at that area seriously should be treated with surgeryoperations immediately without X ray and supersonic checks. Second, the positive check results of suspect patients should behelpful for diagnosis, however the negative ones also could not be excluded of the diagnosis clues. The writers think that theconcomitant observation results with the development of illness are most significant. Third, the emphasis of treatments for thoseinjuries should be paid on abdomen. Explore the abdomen is necessary for the situations that abdominal substantial organs bleedand vacuum organs break, thoracic close drainage is sufficient for treating most thoracic trauma cases. It has been improved to beconvenient to check the thoracic cavities by cutting off the diaphragma temporarily if necessary. Fourth, as it was reported that asmany as 97 per cent of patients will have visceral injury dues to abdominal gunshot wound, all gunshot wounds be done with anexploratory laparotomy without hesitation.
