Abstract
Quantitative determinations of platelet aggregation were made by a modified version of the Wu-Hoak-method in venous blood samples from ten healthy volunteers. It was demonstrated that the extent to which aggregates are formed depends on the rate of flow in the needle and on other methodical influences as well as on the platelet count. Accordingly, no definite conclusions concerning aggregation conditions in vivo can be drawn from the results obtained with venous blood samples. Mit einer Modifikation der Methode von Wu und Hoak wurden bei 10 gesunden Versuchspersonen quantitative Plättchenaggregatmessungen in venösen Blutproben durchgeführt. Eine Abhängigkeit der Aggregatmenge von der Flußgeschwindigkeit in der Entnahmekanüle, anderen methodischen Einwirkungen sowie der Thrombozytenzahl konnte nachgewiesen werden. Bei Verwendung von venösen Blutentnahmen werden deshalb keine schlüssigen Resultate über die Aggregationsverhältnisse in vivo erzielt.Keywords
