外科重症病人血液流变性变化

HEMORHEOLOGICAL CHANGES IN CRITICAL SURGICAL PATIENTS

目的；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：对入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流变学指标。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，刚性指数均有显著性差异（Ｐ＜０．０５～０．０１），红细胞压积，血浆粘度无显著差异（Ｐ＞０．０５）。提示：重症外科病人术后早期存在血液粘度增高，在临床上应注意补充血容量，维持水电解质平衡，降低血粘度，疏通微循环，改善血液流变性。

Aim: To study the changes and regularities of hemorheological parameters in critical surgical patients to provide reference for clinical severity surgery. Method: Hemorheological indexes of 100 control cases were compared with that 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 much higher than normal (p < 0.05 - 0.01 ), while there was no statistical variance in hematocrit and plasma viscosity. Conclusion: High bind viscosity exists in the early stage in critical postoperative patients which strongly recommends clinically bind capacity enlargement, hydroelectrolytic balance,blood viscosity decrease, improvement of microcirculation and hemorheological properties.
