The relationship between complication rate and preoperative levels of hemoglobin and hematocrit was investigated in 186 consecutive below-the-knee amputations for incipient gangrene. Arteriosclerotic amputations had successively higher rates of wound complications and reamputation with increasing hemoglobin and hematocrit. No such association was found among diabetics. Thus, hemoglobin greater than or equal to 7.0 mmol/l and hematocrit greater than or equal to 40 were significant preoperative risk factors in below-the-knee amputation for arteriosclerotic incipient gangrene.
对186例因早期坏疽行膝下截肢的患者，研究了并发症发生率与术前血红蛋白和血细胞比容水平之间的关系。动脉硬化性截肢患者的伤口并发症和再次截肢率随着血红蛋白和血细胞比容的升高而依次升高。在糖尿病患者中未发现此类关联。因此，血红蛋白大于或等于7.0 mmol/l且血细胞比容大于或等于40是动脉硬化性早期坏疽膝下截肢术前的重要危险因素。
