title: The effect of urethane and thiopental sodium on platelet aggregation in vitro and in vivo.
abstract: The potential in vitro (heparinized or citrated PRP) and in vivo effects of urethane and thiopental sodium on arachidonic acid, collagen, or ADP-induced rat platelet aggregation has been investigated. Both anesthetics antagonized platelet aggregation in vitro at concentrations higher than those found in plasma during anesthesia. Neither anesthetic altered the piastrinopenia induced by intravenous administration of these aggregating agents. These findings suggest that both anesthetics are suitable for in vivo platelet aggregation studies.
