翻转课堂教学法在消化内科临床带教的应用评价

目的 探讨翻转课堂教学法在消化内科临床带教的教学效果.方法 选取2018年10月—2019年10月在消化内科进行临床见习的护生48人(全部为女生),按照实习先后顺序,前24人作为试验组,给予翻转课堂教学法教学;后24人作为对照组,采用传统的带教模式.讨论两组护生在理论和操作成绩和对带教满意度方面有无差异.两组学生在试验开始之前的成绩相比较,差异无统计学意义(P>0.05).结果 试验组在理论、操作、教学满意度等方面的成绩均高于对照组,P<0.05.结论 翻转课堂教学法在消化内科的临床带教中有较好的教学效果,可以提高学生的学习成绩和教学满意度.     

PBL教学法在临床实习护士查房中的应用

目的探讨PBL教学法在临床实习护士查房中的应用。方法选取2018年1月-2018年11月于本院实习的42例护士作为研究对象,按照查房方法的差异分为对照组(21例)与观察组(21例),对照组采用传统查房法,观察组采用PBL教学法。比较两组护理业务成绩、临床各项评价指标得分情况以及对护理查房业务的掌握程度。结果观察组临床护理业务兴趣、自主学习能力、学习效率、回答问题踊跃程度等各项指标得分高于对照组,差异有统计学意义(P<0.05)。观察组理论考试、实操训练、病历书写等临床各项评价指标得分高于对照组,差异有统计学意义(P<0.05)。观察组对护理查房业务的掌握程度为95.2%,高于对照组的61.9%,差异有统计学意义(P<0.05)。结论在临床护理业务查房中应用教学法,建议采纳PBL教学法,在提高实习护士理论知识、提升业务水平和综合能力方面价值显著。     

Canal Transportation and Centering Ability in Long Oval Canals: A Multidimentional Analysis

IntroductionThe purpose of this study was to evaluate and compare the centering ability and canal transportation of the ProTaper Next (PTN; Dentsply Maillefer, Ballaigues, Switzerland) and Self-adjusting File (SAF; ReDent-Nova, Ra'anana, Israel) systems in long oval root canals using cone-beam computed tomography imaging.MethodsFifty-six fully formed single-rooted mandibular premolars were selected with a buccolingual canal size 2 to 2.5 times the mesiodistal size at 5 mm from the apex, ranging from a 0°–10° canal curvature with a 5- to 6-mm radius. The teeth were divided into 2 groups (n = 28) and prepared with PTN or SAF according to the manufacturers’ instructions. Cone-beam computed tomographic images were taken in the same position before and after instrumentation using modeling wax. The centering ability and canal transportation were calculated at 3, 6, and 9 mm from the apex in both mesiodistal and buccolingual directions. The mean and standard deviation were calculated, and the Student t test was used for comparative analysis.Resultssignificant difference for canal transportation was observed mesiodistally at 9 mm from the apex (P < .05) where the PTN shaved more dentin in 1 direction. A significant difference for the centering ability was observed at 6 mm buccolingually from the apex (P < .05) where the PTN was less centered in the canal compared with the SAF.ConclusionsBoth SAF and PTN were shown to be safe for being used in long oval canals. SAF resulted in less transportation at the coronal third in the mesiodistal direction and more centered at the middle third in the buccolingual direction compared with PTN.     

基于跨理论模型协同护理模式在急性心肌梗死介入治疗病人中的应用

目的:探讨基于跨理论模型(TTM)协同护理模式在急性心肌梗死(AMI)介入治疗病人中的应用效果。方法:根据随机数字表法将2018年6月—2019年6月收治的88例AMI介入治疗病人分为观察组及对照组各44例,对照组实施常规护理,观察组实施基于TTM的协同护理模式。比较两组干预前及干预6个月后自我效能、疾病管理能力及生活质量改善情况,记录两组不良心脏事件发生率、再入院率及治疗依从率。结果:两组病人干预后自我效能、疾病管理能力、西雅图心绞痛量表(SAQ)总评分比较差异有统计学意义(P<0.05)。观察组病人不良心脏事件发生率(2.27%)、再入院率(4.54%)低于对照组的18.18%、20.45%,差异有统计学意义(P<0.05);观察组病人用药依从率、生活方式管理依从率分别为97.73%和95.45%,高于对照组的75.00%和72.73%,差异有统计学意义(P<0.05)。结论:基于TTM协同护理模式能有效改善AMI介入治疗病人自我效能,提高病人遵医行为及疾病管理能力,减少不良心脏事件的发生,改善病人生活质量。

基于依从性曲线变化规律的分阶段健康指导在维持性血液透析病人中的应用

目的:探讨基于依从性曲线变化规律的分阶段健康指导在维持性血液透析病人中的应用效果。方法:将168例行维持性血液透析治疗的慢性肾病病人根据透析时间将病人分为对照组和观察组,每组84例,对照组行常规健康指导,观察组基于依从性曲线变化规律对病人实施健康指导,比较两组病人干预前后遵医行为、自我护理能力及血液透析并发症发生率。结果:干预后观察组病人遵医行为总分及各维度评分(合理饮食、控制液体摄入、血管通路维护、日常生活管理、规律运动、定期门诊随访)较对照组明显提高(P<0.05);干预后观察组病人自我护理能力总分及相关维度评分较对照组明显提高(P<0.05);观察组病人并发症发生率低于对照组(P<0.05)。结论:基于依从性曲线变化规律的分阶段健康指导能有效提高维持性血液透析病人遵医行为及自我护理能力,从而降低病人血液透析并发症发生率。
