电脑气压止血器的运用对老年患者下肢静脉血栓发生的影响

Effect of the use of computer generated pressure hemostat on venous thrombosis of the lower limbs of elderly patients

目的研究电脑气压止血器的运用对高危老年患者产生下肢静脉血栓的影响。方法选取我院2013年9～12月骨科住院手术患者36例，将其随机分为止血器组和非止血器组各18例。止血器组术中使用止血器；非止血器组术中不使用止血器。观察2组D-二聚体变化情况、下肢静脉血栓形成情况。结果止血器组术后D-二聚体较术前有明显升高；非止血器组术后D-二聚体较术前有明显升高，但升高程度较止血器组为小；止血器组术后D-二聚体较非止血器组术后D-二聚体为高，止血器组术后下肢静脉血栓形成例数较非止血器组为高，差异均有统计学意义。结论电脑气压止血器的运用会增高高危老年患者产生下肢静脉血栓的危险性，必须严格执行技术操作规程，安全使用电脑气压止血器。

Objective To study the effect of computerized pressure hemostat on lower limb deep vein thrombosis in high-risk elderly patients. Methods From September to December 2013, 36 orthopedic hospitalized patients who received operations were divided into the hemostat group and the non-hemostat group with 18 patients in each group. D-dimer changes and lower limb deep vein thrombosis were observed in both groups. Results D-dimer was significantly increased in both groups compared with that before operation, but the extent of elevation in the non-hemostat group was lower than that in the hemostat group. D-dimer and cases of lower limb deep vein thrombosis in the hemostat group was higher than those in the non-hemostat group after operation, which showed significant difference. Conclusions The use of computerized pressure hemostat will increase the risk of lower limb deep vein thrombosis in elderly patients, so the technical operation procedures should be strictly enforced accompany with safely use of computerized pressure hemostat.
