Abstract

Study ObjectiveThe aim of the study was to determine the duration and effects of aspirin on platelet function.Study DesignProspective investigation.SettingBlood samples from volunteers.Patients and MonitoringTen healthy male volunteers took part in this investigation. After having measured baseline hemostatic parameters, 2000-mg aspirin was taken orally. Subsequently, the hemostatic profile had been compiled daily for a duration of 4 days after ingestion.Measurements and Main ResultsPlatelet function was analyzed (1) after 3 hours and (2) daily for 4 days by the platelet function analyzer (PFA-100, Dade Co, Miami, Fla), which represents a sensitive investigation method for measuring platelet function and dysfunction. Routine hemostatic parameters were investigated. Three hours after ingestion of aspirin, abnormal PFA-100 values could be detected. Further detectable elevated values were found during the following 3 days.ConclusionEffects of single-dose aspirin 2000 mg on platelet function were detected after 3 hours and had been lasting for the following 3 days. This result shows that PFA-100 may help by evaluating hemostasis during the preoperative period.
