摘要 本文用WTP-I型毛细管粘度计测定了1988年间临床体外循环期间深度和中度血液稀释各20例的全血比粘度,并分析了红细胞压积(HCT)、血浆蛋白和血温对粘度的影响。文章指出:HCT和血浆蛋白是维持血液粘度的主要因素,转流中血液稀释明显降低血粘度,深度稀释较中度稀释更显著(P<0.001)。血液粘度随术中低温而增高(P<0.05~0.001),但低温对粘度的影响远小于HCT的作用,且可被血液稀释所抵消。文章还就本粘度测定对临床灌注条件的选择提出讨论。 The authors determined the relative viscosity of whole blood in using moderate and profound hemodilution in 20 cases during cardiopulmonary bypass in 1988 with WTPI type capillary viscosimeter anti analysed the effects of hematocrit (HCT), plasma protein and blood temperature influencing the viscosity. The paper showed that hematocrit and plasma proteins were the two main factors in sustaining blood viscosity. Hemodilution reduced markedly the blood viscosity during the perfusion, The blood viscosity was reduced far more in the profound hemodilution than in the moderate hemodilutiort (P<0.001), and was raised together with hypothermia in the operation (P<0.05-0.01). But the effect of hypothermia on the blood viscosity was farless than that of hematocrit and was counteracted by hemodilution. The authors consider that the determination of viscosity playa part in selecting proper condition of clinical perfusion.
