[Behavior of blood gases in patients with craniocerebral trauma at the accident site and at the time of admission to the clinic].
It is known that early mortality after acute craniocerebral trauma (CCT) depends heavily on the extent of any hypoxia and, even more, hypercapnia in the early phase after the trauma. Hypoxia and hypercapnia are very difficult to appraise at the scene of an accident without measuring instruments. It is now generally recognized that appraisal in accordance with the Glasgow coma scale (GCS) is a suitable way of estimating the depth of impairment of consciousness (eye opening in response to stimuli, verbal response to stimuli, motor response to stimuli). The maximum number points is 15, and the minimum, 3. We therefore decided to investigate whether there is a correlation between the degree of impairment of consciousness measured with the GCS and onset of hypercapnia or hypoxia soon after. In 33 patients with acute CCT, arterial blood was taken for analysis of blood gases at the scene of the accident before therapy was started. At the same time, we evaluated the level of consciousness on the basis of the GCS. The blood samples were taken within 6-21 min after the trauma in all patients. It was shown that there is a very close correlation between the severity of trauma (measured with the GCS) and the degree of hypercapnia (r = -0.88). This was true of all CCT patients with multiple trauma without exception. The PaO2 correlates with the severity of trauma (r = 0.60) far less closely, and above all much less consistently.(ABSTRACT TRUNCATED AT 250 WORDS)
