ABSTRACT

Objective To investigate the effects of gelatins and dextran on fibrinogen and platelet glycoproteinⅡb/Ⅲa (GPⅡb/Ⅲa).Methods One hundred and five patients for selective cholecystectomy were randomly divided into four groups. In groupⅠ normal saline 30ml/kg was infused, in groupⅡ dextran-70 30ml/kg,in groupⅢ urea-linked gelatin 30ml/kg and group Ⅳ modified fluid gelatin 30ml/kg. The blood samples were taken before infusion ,two hours and three hours after the infusion, to measure platelet maximum aggregation rate (MAR), levels of Fbg and GPⅡb/Ⅲa,respectively.Results As compared with those in other groups, MAR and level of GPⅡb/Ⅲa decreased significantly in groupⅡ(P
