RANDOMIZED STUDY OF TWO INTERVENTIONS FOR LIQUID ASPIRATION

液体吸入已被证明是老年受试者中最常见的吸入类型，特别是那些患有衰弱、痴呆或抑郁症的受试者。 吸入的后遗症可能是肺炎，这通常是导致死亡的一个因素，也会增加医疗保健费用。 本研究旨在确定两种常用干预措施的短期和长期影响，以消除吸入稀薄液体。 这些包括“（1）下巴向下的姿势，和（2）稠化至蜂蜜粘度或花蜜粘度的液体”。 本研究的第一部分将通过口咽视频透视研究监测这些干预措施对短期内误吸发生的影响。 本研究由两部分组成，第一部分是通过影像学研究初步评价上述入路的抽吸可能性。 第二部分研究了长期随访和两种干预措施对减少肺炎的有效性。

Liquid aspiration has been documented as the most common type of aspiration in older subjects, particularly those suffering from debilitation, dementia or depression. The sequelae of the aspiration can be pneumonia which can frequently be a contributing factor to death and also to increase health care costs. This study proposes to define the short and long term effects of two commonly used interventions to eliminate aspiration of thin liquids. These include a "(1) chin down posture, and (2) liquid thickened to honey viscosity or nectar viscosity". The first part of the study will examine the effects of these interventions on the occurrence of aspiration in the short-term as monitored by oropharyngeal videofluorographic study. The study is composed of two parts, the first of which is the initial evaluation by radiographic study as to the possibility of aspiration on the above listed approaches. The second part examines the long term follow up and the effectiveness of the two interventions on the reduction of pneumonia.
