运用数字多媒体传播媒介对促进全膝关节置换患者术后康复的效果评价

目的:探讨运用数字化多媒体传播媒介对促进全膝关节置换术后患者功能锻炼依从性及膝关节功能康复的效果。方法:219例行全膝关节置换术后患者根据入院日期分为试验组和对照组。试验组利用数字化多媒体传播媒介分阶段进行健康教育指导,对照组仅给与常规健康教育指导。比较①两组患者术后功能锻炼完成情况;②入院时、出院时和出院后3个月膝关节功能的HSS评分。结果:两组患者术后功能锻炼完成情况差异有统计学意义(p <0.05);入院时两组患者HSS评分无统计学意义,出院时和出院后3个月的两组HSS评分的差异具有统计学意义(p <0.05),试验组得分高于对照组。结论:借助数字化多媒体传播媒介进行术后康复健康教育指导,有助于提高全膝关节置换术后患者功能锻炼的依从性和改善膝关节功能。

膀胱冲洗液温度控制对改良前列腺剜切术后患者康复的影响

目的:探讨和比较不同温度冲洗液对膀胱冲洗的效果,从护理角度分析影响“低压灌注下经尿道四区分割法等离子体前列腺剜切术(four-area division transurethral plasmakinetic enucleation of prostate, FPKEP)”后发生膀胱痉挛和出血的相关因素。方法:对2011年6月~2013年6月间行剜切术的119例患者进行随机分组,实验组60例,对照组59例。实验组给予接近人体生理体温(35℃ ±177;2℃)的冲洗液,对照组给予室温(22℃ ±177;2℃)的冲洗液,分别进行膀胱冲洗,观察记录两组患者术后膀胱冲洗时间、冲洗液量、膀胱痉挛发生次数、出血情况、留置尿管时间、住院天数以及护理满意度。结果:实验组膀胱冲洗时间、冲洗液量、膀胱痉挛发生次数、出血情况、留置尿管时间以及住院天数均低于对照组,而患者满意度实验组高于对照组,P <O.05差异有统计学意义。结论:膀胱冲洗液温度对术后膀胱痉挛和出血情况有直接影响。用接近人体生理体温(35℃ ±177;2℃)的冲洗液对膀胱进行冲洗,可减少术后并发症,提高治疗效果及患者满意度。

Voltammetric Method Using Multi-Walled Carbon Nanotubes Modified Glassy Carbon Electrode for the Determination of Terbutaline Sulfate in Pork Sample

Electrochemical properties of terbutaline sulfate (TBS) at the glassy carbon electrode modified with multi-walled carbon nanotubes (MWNTs) were explored by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). The response was evaluated with respect to pH, scan rate and other variables. Some electrochemical parameters, such as the charge number and proton number, were calculated. The results indicated that TBS underwent irreversible oxidation at the modified electrode, which was an adsorption-controlled process with two protons and two electrons. The reductive peak current of TBS significantly increased and the peak potential shifted negatively at the modified electrode, thus resulting in an electrode for TBS. The current was proportional to the concentration of TBS over 1.12 and 141 μM with a detection limit of 0.34 μM (at S/N = 3). The modified electrode showed good sensitivity, selectivity and stability for the determination of TBS in pork sample.
