简介:摘要:目的 对 6S管理在护理技术强化训练中的应用效果予以探究。方法 选取本院 2014级护生 253名在实训教学中予以常规管理作为对照组, 2015级护生 230名在实训教学中予以 6S管理作为观察组。对两组护生护理技术实训考核成绩、教学满意度、综合素质自我评定优良情况进行对比。结果 观察组护生护理技术实训考核成绩高于对照组( P<0.05);观察组护生教学满意度 83.48%,高于对照组的 55.34%( P<0.05);除人际沟通能力与语言表达能力外,观察组护生其他项目综合素质自我评价优良例数均高于对照组( P<0.05);上述差异均有统计学意义。结论 6S管理在护理技术强化训练中的应用效果显著。

简介:【摘 要】目的:了解白细胞(White Blood Cell, WBC)与C反应蛋白(C-reactive protein,CRP)检测在社区门诊患者中的临床价值。方法:于2018年6月-2020年8月本社区门诊中选择64例疑似病毒性感染患者及疑似细菌性感染患者作为实验样本,分别将其设定为A组、B组,选择同期门诊64例健康体检者设定为C组,所有受试者均进行WBC、CRP的检测,对检测结果存在的差异进行比较。结果:A组的WBC、CRP同C组行比较,数据间无统计学意义, P>0.05;B组的WBC、CRP均高于A组、C组,数据间存在统计学意义,P<0.05。结论:CRP、WBC在社区门诊联合检测,在临床上具有早期判断、识别感染的价值,值得借鉴和采纳。
简介:【摘要】目的: 探讨平行双锁定钢板固定方式对肱骨远端 C 型骨折的治疗价值。 方法: 选取 2017 年 1 月至 2017 年 12 月本院进行治疗的肱骨远端 C 型骨折成人病患 60 例作为研究对象,采取尺骨鹰嘴截骨入路方式将肱骨间骨折部位显露出来,完成骨折复位后,使用肱骨内侧、外侧解剖镇定钢板将骨折处固定好,同时,应用尺骨鹰嘴张力进行固定。术后 3d 开始进行肘关节功能康复训练,出院后进行 10 个月至 24 个月的定期随访,拍摄肘关节正位、侧位片和根据 Cassebaum 评分系统对患者的肘关节功能进行评价。 结果: 60 例患者均给予 10-24 个月的随访,结果发现,所有患者均痊愈,肘关节功能根据 Casebaum 评价标准评定为优的患者有 48 例,为良的患者有 7 例,为可的患者有 5 例,肘关节功能优良率为 91.67% 。 结论: 平行双锁定钢板固定方式对肱骨远端 C 型骨折 实施 治疗 ,该方式具有较强的 力学稳定性 ,能帮助患者尽早进行早期肘关节康复训练,临床 价值 显著。
