骨科术后深静脉血栓影响因素的Logistic分析

Logistic regression analysis on DVT after orthopedic operation

目的研究骨科术后深静脉血栓的影响因素,为日后针对性预防提供帮助。方法收集符合要求的骨科手术病历,根据患者自身情况及手术情况,从性别、年龄、血型、合并其他疾病、手术时间、术中出血等8个指标出发,应用Logistic回归分析观察这些指标与术后深静脉血栓的关系。结果统计结果显示,年龄、血型及手术时间三个指标的统计结果 P<0.05,具有统计学意义。结论手术时间长伴有DVT易患血型的高龄患者术后发生深静脉血栓的几率较大,在进行术后预防时,针对此类病人更应提高警惕,以降低此并发症的发生率。

Objective To explore the influence factors of deep venous thrombosis（DVT） after the orthopedic operation, in order to help us to prevent DVT. Methods We collected medical records which were according to the standards and used a multivariate logistic re gression analysis on the relationship between 8 indicators, such as gender, age, blood type, complication, operation condition, and DVT. Results The analysis results showed that three indicators （age,blood type and operation time） had statistical significance （P 〈 0.05 ）. Conclusions The probability of DVT after operation is high in patients who satisfy these indicators. In order to reduce the probability, we should pay more attention to these patients.
