[A new method of studying blood aggregation in geriatric surgical patients].
A new technique of nephelometry based on the determination of optic radius of platelets and their aggregates has been tested in surgical patients of very advanced age with abdominal pathology. The technique in question makes it possible to use subthreshold inducer doses compatible with their real concentration in vivo. The nature of changes in platelet aggregation at preoperative stage has been described, postoperative course of hyperaggregation syndrome has been followed and qualitative disorders in aggregate forming processes have been specified. It has been shown that intravascular blood irradiation with low-intensive laser is effective for the correction of high platelet sensitivity.
