目的探讨不同清洗方法对血管钳咬合面的清洗效果。方法抽取骨科四肢骨折择期手术术后血管钳120件,随机分为试验组和对照组各60件,实验组在刷洗血管钳咬合面时顺齿牙槽细小凹凸槽走向来回用力刷洗,对照组刷洗血管钳咬合面时在齿牙槽上来回平刷。采用目测、8倍放大镜、ATP生物荧光法评价清洗效果,比较两种方法的清洗质量。结果经目测法检查两组器械合格率均为100%。8倍放大镜检测实验组和对照组合格率分别为91.66%和55.00%,试验组合格率明显高于对照组(P<0.01)。ATP生物荧光检测,顺咬合面齿牙槽走向擦拭采样,试验组和对照组合格率分别为76.66%和20.00%;咬合面齿牙槽平擦拭采样,试验组和对照组合格率分别为85.00%和51.66%,试验组合格率明显高于对照组(P<0.01)。结论刷洗血管钳咬合面时,顺咬合面齿牙细小凹凸槽走向来回刷洗可显著提高清洗质量。
Objective To investigate the cleaning effect of different cleaning methods on the occlusion surface of vascular forceps. Methods 120 patients with postoperative orthopedic fracture of extremity fracture were randomly divided into experimental group and control group with 60 cases each. The experimental group scrubs the small concave and convex grooves along the alveolar groove with brushing brushing Vascular clamp occlusal surface in the tooth groove on the back and forth flat brush. Visual inspection, 8x magnifying glass and ATP biofluorescence were used to evaluate the cleaning effect. The cleaning quality of the two methods was compared. Results The visual test showed that the passing rate of both instruments was 100%. Eight times the magnifying glass test group and the control group passing rate was 91.66% and 55.00%, the test group was significantly higher than the passing rate of the control group (P <0.01). ATP biofluorescence detection, along the occlusal surface alveolar wipe Sampling, the test group and the control group pass rates were 76.66% and 20.00%; occlusal surface alveolar flat wipe sampling, the test group and the control group pass rates were 85.00% And 51.66%, respectively. The passing rate of experimental group was significantly higher than that of control group (P <0.01). Conclusions When brushing the occlusal surface of the vascular forceps, the small concave and convex grooves along the occlusal surface can brush back and forth, which can significantly improve the cleaning quality.
