Abstract:To evaluate the pathogenetic role of cerebral blood flow (CBF) changes occurring before and during the development of acute mountain sickness (AMS), peak mean middle cerebral artery flow velocities (V¯¯¯MCAV¯MCA<math display="inline" id="ML1" overflow="scroll" altimg="eq-00001.gif"><msub><mover accent="true"><mi>V</mi><mo stretchy="true">¯</mo></mover><mrow><mo>MCA</mo></mrow></msub></math>) were assessed by transcranial Doppler sonography in 10 subjects at 490-m altitude, and during three 12-min periods immediately (SA1), 3 (SA2), and 6 (SA3) h after decompression to a simulated altitude of 4,559 m. AMS cerebral scores increased from 0.16 ± 0.14 at baseline to 0.44 ± 0.31 at SA1, 1.11 ± 0.88 at SA2(P < 0.05), and 1.43 ± 1.03 at SA3(P < 0.01); correspondingly, three, seven, and eight subjects had AMS.

These results suggest that CBF is not important in the pathogenesis of AMS and shows substantial interindividual differences during the first hours at simulated altitude.
