外科重症病人血液流变性变化

探讨外科重症病人血流变指标的变化规律,为外科重症治疗提供参考。方法：对八住加强医疗病房的重症病人６０例与１００例正常对照组比较血液充变学指标。结果：外科重症病人的全血高、中、低切粘度,粘弹性,红细胞聚集指数,刚性指标均有显著性差异,红细胞压积、血浆粘度无显著差异。

HEMORHEOLOGICALCHANGES IN CRITICAL SURGICAL PATIENTS

Aim To study the changes and regularities ofhemorheological parameters in critical surgical patients to provide reference for clinicalseverity surgery. Method Hemorheological indexes of 100 control cases were compared withthat of 60 critical cases admitted to SICU. Result Whole blood viscosity under high,media and low shear rate, viscolasticity, RBC aggregation index and TK value were muchhigher than normal (p<0.05～0.01), while there wasno statistical variance in hematocrit and plasma viscosity. Conclusion High bloodviscosity exists in the early stage in critical postoperative patients which stronglyrecommends clinically blood capacity enlargement, hydroelectrolytic balance, bloodviscosity decrease, improvement of microcirculation and hemorheological properties.
