ABSTRACT

OBJECTIVES: To examine the accuracy of standard trauma-room chest x-ray films in assessing blunt abdominal trauma and to determine the significance of missed injuries under these circumstances. DESIGN: A retrospective review. SETTING: A regional trauma unit in a tertiary-care institution. PATIENTS: Multiply injured trauma patients admitted between January 1988 and December 1990 who died within 24 hours of injury and in whom an autopsy was done. INTERVENTION: Standard radiography of the chest. MAIN OUTCOME MEASURES: Chest injuries diagnosed and recorded by the trauma room team from standard anteroposterior x-ray films compared with the findings at autopsy and with review of the films by a staff radiologist initially having no knowledge of the injuries and later, if injuries remained undetected, having knowledge of the autopsy findings. RESULTS: Thirty-seven patients met the study criteria, and their cases were reviewed. In 11 cases, significant injuries were noted at autopsy and not by the trauma-room team, and in 7 cases these injuries were also missed by the reviewing radiologist. Injuries missed by the team were: multiple rib fractures (11 cases), sternal fractures (3 cases), diaphragmatic tear (2 cases) and intimal aortic tear (1 case). In five cases, chest tubes were not inserted despite the presence (undiagnosed) of multiple rib fractures and need for intubation and positive-pressure ventilation. CONCLUSIONS: Significant blunt abdominal trauma, potentially requiring operative management or chest-tube insertion, may be missed on the initial anteroposterior chest x-ray film. Caution must therefore be exercised in interpreting these films in the trauma resuscitation room.

ABSTRACT

The ability of level I trauma units to operate efficiently may be hampered by the presence of a number of patients with an excessive length of stay (LOS). In an attempt to determine causes for and suggest potential solutions to the long-term occupation of beds in an acute care trauma facility, the cases of patients with extended LOSs in a level I trauma unit were examined. Study patients were survivors admitted between January 1, 1986, and December 31, 1989. Patients with a LOS greater than one standard deviation above the mean (n = 221) were assigned to the Long LOS group, and the remaining 1250 patients to the Short LOS group. Long and Short LOS patient groups were compared on a number of variables including injury Severity Score, number of body systems injured, surgical procedures required, blood products used, AIS scores per body region, and patient wait days. Both an increased severity of injury and a lack of available chronic and rehabilitation beds for the head-injured patients contributed to excessive patient LOS in this acute care setting. Additional rehabilitation and chronic care beds are required to free acute care beds for the efficient operation of a level I trauma unit.
