[State of regional hemodynamics in patients with vibration disease during sanatorium treatment (reographic studies)]

The state of the regional haemodynamics was studied in 216 patients with vibration disease kept on balneologic therapy. Vibration disease was the result of "local" vibration in 104 patients, and that of combined vibration -- in 112. Rheographic studies of the peripheral blood flow demonstrated disorders of the regional haemodynamics in 76% of the patients, their severity depending on the stage of the pathological process. Rheogrammes recorded during spontaneous attacks of angiospasm or following a cold test revealed a distinct, sometimes complete levelling of the rheographic elements predetermined by the angiospastic state of the peripheral vessesl. The revealed changes in the functional state of the regional flow were of a similar angiospastic nature and reflected the severity of the pathological syndrome, as well as the site of the prevailing vibration effect. Dynamic rheographic studies conducted in patients following balneological treatment (nitrogen-thermal or bromiodine baths) revealed positive changes in the qualitative and quantative rheographic parameters indicating normalization or improvement of the peripheral circulation in vibration disease cases. A comparative assessment of the immediate therapeutic effect of the balneological treatment demonstrated more distinct positive shifts in the rheographic parameters of the regional haemodynamics following a course of nitrogen-thermal baths.
