目的解决骨折肢体在术前消毒时因抬高患肢造成骨折处成角问题。方法自制肢体牵升架,其结构由提升臂、托肢架、固定齿轮和固定杆四部分组成。将100例股骨骨折需要手术治疗的患者,按入院先后顺序随机分为观察组和对照组,各50例。观察组采用肢体牵升架牵升患肢,对照组采用人工牵拉法牵升患肢。观察两组牵引效果,消毒时肢体污染情况和消毒所需时间。结果牵引有效率观察组78.0%,对照组54.0%,两组比较,差异有显著性意义(P<0.05);观察组消毒时无1例污染,污染率为零;对照组消毒时污染9例,污染率18.0%,两组比较,差异有显著性意义(P<0.01);观察组消毒时间平均(17.7±2.2)min,对照组(20.4±3.2)min,两组比较,差异有显著性意义(P<0.01)。结论肢体牵升架既能抬高患肢,又具有效牵引作用,能明显减轻骨折处成角,且操作简便。
Objective To solve the problem of angulation of fractures caused by elevation of limbs when preoperative disinfection of fractured limbs. Methods Self-made body pull-up frame, the structure of which consists of a lifting arm, a supporting frame, a fixed gear and a fixing rod. 100 patients with femoral fractures requiring surgical treatment were randomly divided into observation group and control group according to admission sequence, 50 cases each. The limbs were used to pull the affected limbs in the observation group and the control limbs were used to pull the limbs. Observe traction effect of two groups, disinfection of limbs and disinfection of the time required. Results The effective rate of traction was 78.0% in the observation group and 54.0% in the control group. There was a significant difference between the two groups (P <0.05). In the observation group, no one was found to be contaminated and the contamination rate was zero. In the control group, 9 , The pollution rate was 18.0%. There was significant difference between the two groups (P <0.01). The disinfection time in the observation group was (17.7 ± 2.2) min on average and in the control group (20.4 ± 3.2) min, the difference was significant Significance (P <0.01). Conclusions The limb-lift frame can elevate the affected limbs and also has effective traction, which can obviously reduce the angulation of the fracture and is easy to operate.
