[Changes in the oxygen balance of the body in the acute period of hemorrhagic shock and after resuscitation under the effect of intravascular helium-neon laser irradiation of the blood].
The effect of intravascular laser irradiation of the blood (ILIB) on the oxygen budget of the body and blood acid-base balance in the acute period of hemorrhagic shock and after resuscitation was studied in experiments on dogs. Duration of hypotension was 2 h. Laser therapy was started from the 5th-8th min of hypotension and lasted for 45 min; it was performed with a He-Ne laser (ALOK-1, 1 mWt power at the tip of the light guide, wavelength 633 nm) introduced in the right jugular vein. Exposure to ILIB in the acute period of hemorrhagic shock was conducive to creation of favorable conditions for realization of the compensatory mechanisms aimed at improvement of circulation and gas exchange in the lungs, at provision of delivery of oxygen to tissues and its utilization, and, hence, promoted the survival of animals by triggering the regulatory mechanisms of redistribution of the regional bloodflow, improvement of tissue perfusion, and possibly, of oxyhemoglobin dissociation processes in red cells.
