Early hemorrhelogical changes of oleic acid-induced RDS in dogs / 第三军医大学学报

The hemorrheological changes were observed in dogs in the first 2 hours after they were inflicted with oleic acid-induced RDS.It was found that hematocrit,absolute viscosity and relative viscosity of whole blood were significantly increased but plasma viscosity showed no marked changes.These facts imply that in the early stage of oleic acid-induced RDS,the hemorrheological changes were characterized by hemoconcentration and decrease of the trans-formability of erythrocytes,which might be one of causes of the functional failure of pulmonary microcirculation.
