应用气道物理学原理有助于解释哮喘与胃食管反流的关系
2010/04/14
研究发现胃食管反流(GER)与哮喘相关,但两者的具体关系尚不完全清楚。一些研究将GER作为哮喘的一个危险因素。此外,GER还与上呼吸道样鼻窦炎和阻塞性睡眠呼吸暂停(OSA)相关,认为GER是导致后两种疾病的原因之一。GER能导致气道相关疾病恶化,越来越多的证据表明气道阻塞是发生GER的危险因素。
本文根据气道和食管解剖学结构,采用物理学原理预测可能会发生的疾病,并举例说明气道阻塞为胃食管反流重要危险因素这一假说。

Gastroesophageal reflux (GER) and asthma have been linked, but the true nature of this relationship is incompletely understood. Most of the literature examining this association has implicated GER as the factor contributing to asthma. GER has also been linked to conditions of the upper airway like sinusitis and obstructive sleep apnea (OSA), and once again, usually presumed to be the causative factor. While GER seems to be capable of exacerbating airway disease, mounting evidence suggests that airway obstruction is a risk factor for developing GER. This article examines the principles of physics that predict what should occur given the anatomy of the airway and the esophagus, and provides multiple examples of disease associations that appear to support the hypothesis that airway obstruction is a significant risk factor for development of gastroesophageal reflux.
