简介:目的:评估3D骨科医患沟通系统在骨关节病科试运行的临床效果。方法:选取河南省洛阳正骨医院2014年6月-2014年11月骨关节病科收治的达到膝关节置换手术指征的膝关节骨关节病患者(仅单膝)共67例,用抛硬币的方法随机分为常规谈话组和3D软件谈话组,记录各个患者术前谈话用时、患者对于病情及手术的理解程度评分以及医患沟通满意程度评分。并用统计学方法分析,比较常规谈话组和3D软件谈话组的统计学差异。结果:3D软件谈话组和常规谈话组的谈话时间为3D软件谈话组(393.06±80.03)秒和常规谈话组(490.20±124.78)秒,两者相比具有高度统计学差异(P〈0.01);两组患者对于膝关节骨性关节炎术前谈话的理解程度评分为3D软件谈话组(8.16±0.81)和常规谈话组(8.14±0.76),两者相比无统计学差异(P〉0.05);两组患者对其术前谈话的满意度评分为3D软件谈话组(8.19±0.74)和常规谈话组(7.66±0.91),两者相比具有统计学差异(P〈0.05)。结论:在使患者对术前谈话内容达到相同理解程度的情况下,借助3D交互式医患沟通系统进行谈话比常规模式用时更少,且患者最终满意度更高。

简介:摘要目的探讨氢氧化钙碘仿糊剂((iodoform-calciumhydroxide,ICH)、氢氧化钙水糊剂(CalciumHydroxidePaste,CHP)及氧化锌丁香油糊剂(zincox-ideengenol,ZOE)3种盖髓剂用于年轻恒牙外伤露髓的应用效果.方法选择45例外伤露髓的年轻恒牙71颗,接受活髓切断术,其中33颗采用ICH盖髓,28颗采用CHP盖髓,10颗采用ZOE盖髓,术后定期复查牙根发育及牙冠情况,同时进行2年的随访跟踪观察病情变化.结果2年后复查显示,ICH组成功率为100%,CHP组成功率为85.71%,ZOE组成功率为30%,ICH组与CHP组疗效相当(P>0.05),但均优于ZOE组(P<0.05).结论ICH对年轻恒牙外伤露髓效果理想,建议CHP不宜单独使用,ZOE宜用于间接盖髓术.关键词年轻恒牙;盖髓剂;外伤露髓中图分类号R781文献标识码B文章编号1008-6315(2015)12-0058-02
