摘要
目的 确定影响断指再植成活的因素 ,进而用量化指标探讨断指再植的适应证。 方法 分析 1999年 1月～ 2 0 0 2年 11月 12 3 1指的断指再植资料 ,对动脉损伤程度、指背皮肤损伤程度、损伤类型、离断平面、患者血红蛋白含量、骨与关节损伤程度、肌腱损伤程度、神经损伤程度、断指再通血时间进行评分并与断指再植成活情况进行Logistic回归分析。另外随机抽取再植成功和失败者各 5 0例 ,与经过Logistic回归分析对断指再植成活确实存在影响的因素建立两分类判别方程。 结果 动脉损伤程度、指背皮肤损伤程度、损伤类型、离断平面、患者血红蛋白含量对断指再植成活有明显影响 ,判别方程为Z =6 42X1+5 3 1X2 +4 3 5X3 +3 2 6X4+3 15X5。 结论 用量化可以判定断指再植的适应证。
Objective To determine the factors influencing the survival rate and then quantifying the indication in digital replantation. Methods From January 1999 to November 2002,1 231 digit replantations were reviewed retrospectively.Analysis of Logistic regression was carried out between survival rate and injury degree of artery,skin,tendon,bone and nerve,mechanism of injury,severed levels,repassing duration and haemoglobin levels. Records of 50 failed and 50 succeeded fingers were selected at random and discriminant equation was made according to the factor selected by Logistic regression. Results The factors of injury degree of artery and skin,mechanism of injury,severed levedls and haemoglobin levels affected the survival rate significantly.The discriminant equation was that Z=6.42X 1+5.31X 1+4.35X 3+3.26X 4+3.15X 5. Conclusions The five factors mentioned above affect the survival rate of digital replantation.The indication of digital replantation could be quantified with the discriminant equation.
