[Functional studies in blunt thoracic trauma with special reference to perfusion and ventilation scintigraphy]

In 10 patients we carried out a routine chest X-ray examination together with an arterial blood gas analysis, spirometry and a combined pulmonary perfusion/ventilation scintigram. Scintigraphy was shown to be the most sensitive method in the detection of impaired post-traumatic pulmonary function. Since it is a time-consuming method requiring sophisticated equipment it is of limited value for routine examinations. Spirometric results during the immediate post-traumatic period are difficult to interpret as a result of severe chest pains which may inhibit respiratory movements. Arterial blood gas analysis which is easily performed is of high value in accessing the actual pulmonary function.
