氧气驱动加压吸入特布他林及氨溴索治疗毛细支气管炎疗效观察

目的：探讨氧气驱动加压吸入特布他林及氨溴索治疗毛细支气管炎的疗效。方法：2008年1月-2011年1月,将我院收治的96例毛细支气管炎患儿分为治疗组、对照组。对照组采用综合治疗：抗病毒、吸氧、解痉、化痰、平喘、镇静及布地奈德雾化吸入治疗;治疗组在对照组的基础上采用特布他林雾化液2.5mg、盐酸氨溴索注射液15mg加生理盐水2ml,由氧气驱动加压雾化吸入,氧流量5~6L/min,2次/d,每次吸入10~15min,疗程5~7d。对两组疗效以及症状、体征持续时间等进行对照评价。结果：两组咳嗽消失时间比较差异无显著性（P〉0.05）,但在喘憋、哮鸣音、湿啰音及住院时间方面治疗组与对照组比较差异有显著性（P〈0.05）。结论：氧气驱动加压吸入特布他林及氨溴索治疗毛细支气管炎疗效确切。

Analysis and Improvement of Standing-Up Action for Elderly People from a Chair Using a Cushion-Type Support Tool

This paper reports the problems that elderly people have when they stand up from a chair, and proposes an adequate standing-up procedure that solves these problems. The important points for an adequate standing-up procedure are ＂leaning the upper body forward＂ and ＂pulling the legs to the side＂. Furthermore, this paper proposes a standing-up support tool. The characteristics of the support tool are a cushion-type shape with an adjustable flange and an air-pressure-driven mechanism. When the proposed standing-up procedure and support tool are applied to elderly people, the measured values related to standing-up, such as maximum acceleration, arm force, standing-up time, heel position and forward-bending angle, are improved. Furthermore, elderly people felt that it made the standing-up action easy. We could confirm the effectiveness of the proposed standing-up procedure and support tool.
