安全型无指硬底约束手套在防止患者术后拔管中的应用

目的：探讨安全型无指硬底约束手套对术后患者的约束效果。方法采用随机抽样的方法，将100例术后患者随机分为观察组（50例）和对照组（50例），分别应用安全型无指硬底约束手套及常用约束带对患者进行防护性约束。结果观察组患者拔管及并发症的发生率显著低于对照组（ P＜0．05、P＜0．01）。结论安全型无指硬底约束手套的防护性约束效果明显优于目前常用的约束带。     

Subantimicrobial dose doxycycline as adjunctive treatment for periodontitis. A review

BACKGROUND: Subantimicrobial dose doxycycline (SDD--20 mg doxycycline twice daily) is indicated as an adjunctive treatment for periodontitis. Doxycycline downregulates the activity of matrix metalloproteinases (MMPs), key destructive enzymes in periodontal disease. Current understanding of periodontal pathogenesis suggests that MMPs play a major role in the destruction of periodontal tissues, leading to the clinical signs of periodontitis. Research supports that downregulation of MMPs by SDD confers benefit to patients with periodontitis. METHOD: We review the clinical, microbiological and safety data relating to the use of SDD in patients with periodontitis, and consider the historical events that led to the development of adjunctive SDD as a treatment for periodontitis. RESULTS: Studies have shown that SDD, when prescribed as an adjunct to scaling and root planing (SRP), results in statistically and clinically significant gains in clinical attachment levels and reductions in probing depths over and above those that are achieved by SRP alone. SRP must be thorough and performed to the highest standard to maximise the benefits of adjunctive SDD. SDD does not result in antibacterial effects, or lead to the development of resistant strains or the acquisition of multiantibiotic resistance. The frequency of adverse events is low, and does not differ significantly from placebo. CONCLUSIONS: Adjunctive SDD confers clinical benefit to patients with periodontitis. A comprehensive treatment strategy is suggested, involving patient education and motivation, reduction of the bacterial burden by SRP, host response modulation with SDD, and periodontal risk factor modification.     

表面水分和不同种类的手套对于硅橡胶印模材聚合时间的影响

目的:本文研究了表面水分和不同种类的手套对于硅橡胶印膜材料聚合时间的影响.方法:使用3种手套:一次性聚乙烯塑料薄膜手套,灭菌橡胶医用手套(无粉),以及橡胶检查手套(预撒粉),分别在潮湿和干燥环境下手动混合DENT SILICONE-PLUS重体型硅橡咬印模材,并记录其硬化时间.结果:干燥情况下使用塑料薄膜手套时,橡胶印模材聚合时间最短,平均2分10秒;乳胶材料和表面水分均可延长聚合时间,达到3～分钟时间;而预撒粉则可显著延长聚合时间,超过1小时.结论:临床运用硅橡胶制取印模时,建议使用一次性聚乙烯塑料薄膜手套在干燥环境下进行操作,预撒粉的橡胶检查手套必须更换,以避免操作失败.     

Biomechanical performance of powder-free examination gloves

Biomechanical performance studies were undertaken for powder-free, latex and nitrile examination gloves. Using standardized tests, examination glove performance was judged by measuring glove thickness, glove puncture force, glove tape adhesion force, glove donning force, glove stiffness, and immediate unrecovered stretch. Even though the nitrile examination gloves were thinner than the latex examination gloves, they exhibited a greater puncture resistance. In addition, tape adherence to the N-Dex nitrile glove was the lowest. Moreover, measurements of the handling characteristics of the nitrile examination gloves demonstrated that they are an acceptable alternative to latex examination gloves. While these biomechanical studies demonstrate the superiority of the nitrile examination gloves, clinical glove evaluation is still needed to determine their performance in the health care setting.     

两种约束方式在临床中的应用效果

目的分析两种约束方式在临床中的应用效果。方法便利抽样法选择2011年10月至2013年10月入住解放军总医院南楼心血管内科的患者72例为研究对象,按入院时间先后将其分为观察组和对照组,每组各36人。对照组患者采用传统约束带约束,观察组患者采用改良后新型约束手套约束,比较两种约束方式下患者的管道脱出率、约束带并发症发生率、家属接受度及护士的满意度。结果观察组患者的管道脱出率、约束带并发症发生率低于对照组,差异均有统计学意义(均P0.05);家属接受度、护士满意度亦明显优于对照组,差异均有统计学意义(均P0.01)。结论改良后新型约束手套较传统约束带在临床中的应用效果更好,推荐在临床广泛使用。
