[The effect of intravascular helium-neon laser blood irradiation on the state of the compensatory processes in the acute period of hemorrhagic shock and after resuscitation].

The effect of low-intensity intravascular laser blood irradiation on morphofunctional characteristics of erythrocytes and circulation parameters has been studied experimentally on 22 adult inbred anesthetized dogs of both sexes 9 to 23 kg of weight during a 2-hour hemorrhagic shock and in the first hours after resuscitation. It has been established that the use of intravascular laser blood irradiation during 45 min of hemorrhagic shock stabilizes erythrocyte membranes and improves myocardial function. Hyperdynamic and hyperperfusion syndromes were significantly more pronounced in the postresuscitation period in animals treated by intravascular laser blood irradiation than in the control. Thus, the efficacy of intravascular laser blood irradiation was associated both with the recovery of erythrocyte cytoarchitectonics and the enhancement of myocardial contractility.
