慢性支氣管炎Chronic Bronchitis
Chronic Bronchitis
慢性支氣管炎
Chronic bronchitis is a condition associated with excessive tracheobronchia mucus production sufficient to cause cough with expectoration for at least 3 months of the year for more than 2 consecutive years. Several subclassifications have been proposed: ①simple chronic bronchitis describes a condition characterized by mucoid sputum production; ②chronic mucopurulent bronchitis is characterized by persistent or recurrent purulence of sputum in the absence of localized suppurative diseases such as bronchiectasis; ③chronic bronchitis with obstruction deserves a separate classification characterized by presence of airway obstruction as assessed by the used of the forced expiratory vital capacity maneuver; and ④chronic asthmatic bronchitis. The patient with chronic asthmatic bronchitis has a long history of cough and sputum production with a later onset of wheezing, whereas the asthmatic with chronic obstruction gives a long history of wheezing with later onset of chronic productive cough. form www.med66.com
由于氣管、支氣管粘液分泌過多,引起咳嗽咯痰,1年中至少有3個月并連續(xù)2年以上者,稱為慢性支氣管炎。它可以分為以下幾種類型:①單純性慢性支氣管炎,其特征為咳粘液性痰;②慢性粘液膿性支氣管炎,其特征是反復(fù)的或持續(xù)的咳膿痰,但肺部并無化膿性病變,如支氣管擴(kuò)張;③慢性支氣管炎伴阻塞,其特征為用力呼氣肺活量測定時有氣道阻塞的表現(xiàn);④慢性哮喘性支氣管炎,其特征是患者有長期的咳嗽及咯痰史,后來肺部出現(xiàn)哮鳴者,因此與哮喘伴慢性氣管阻塞的病人不同。后者是長期有哮鳴者,后來才出現(xiàn)慢性咳痰。
