Diagnosis of a breather. Clinical manifestations
(1) different parts of the onset of the lesions, breathing may be different manifestations, such as the ring home stenosis in the throat symptoms to inspiratory dyspnea and inspiratory stridor main funeral; esophageal tracheal thin one when can cause aspiration pneumonia, and rapidly increasing difficulty breathing; when lesions in the bronchioles, then the performance of gas-day dyspnea and expiratory wheeze. Pathology of airway luminal narrowing, increased flow resistance through the air.
(2) Level: Light; breathing is difficult, but it can lie horizontally, generally speaking, can a positive move, no place sweet, sense of normal; of: breathing difficulties, can not lie horizontally, to say difficult to wash, stool are very difficult, no hair Shao, consciousness is normal; re: breathing difficulties, can not move, difficulty speaking, can not engage in activities, made presentations, normal dry, should identify obstacles, stool incontinence.
Diagnosis of wheezing 2. Auxiliary examination
(1) auscultation: thyroid cancer, lung cancer and breathing pressure, auscultation of the left side more than a difference Ke, often limited, with distant sense of rales, inspiratory clear. When tracheal foreign body, with rales change position, so obviously different. General bronchitis asthma can hear in the lungs wheeze, rales on about non-discrimination, does not call for changes in body position change.
(2) inspection items
1) The peripheral blood test, total number of leukocytes.
2) chest X-ray examination, the trachea and surrounding soft tissues to understand the situation there to determine tumor location.
3) The chest CT examination can estimate the extent of disease and the degree of airway obstruction. Bronchoscopy, can intuitively understand the lesions, and can make the inspection, but had significant stenosis in the trachea does not apply endoscopic surgery to avoid obstruction caused by edema and increased the degree.
5) lung volume icon obstructive ventilatory defect, a second rate decreased, suggesting a wide range of airway stenosis.
6) reversibility of airway stenosis: a agonist inhalation households, expansion of bronchus, forced expiratory volume in one second measured rate of improvement, the amount of a smoke inhalation before Is the amount of people / Is the amount of pre-inhalation XIOO%, with rate of improvement is solved on the> 20% reversible, can be considered the main reason airway obstruction from the bronchial muscles recover from illness flat twin.
7), airway responsiveness test: usually inhaled acetylcholine or group of rubber was reduced after the extent of a judge. That is pre-prepared series of solutions of different concentrations, since the concentration of aerosol inhalation began to determine the amount of each concentration of the second to a second volume down more than 15% of that of the concentration. When using acetylcholine 750g1000flg below to determine the increased airway reactivity, there allergic.
8) ECG.
9) IgE (RAST).
10) The skin allergy test.
11) plastic basophils release test group.
12) blood gas analysis.
13), sputum examination (microscopy, culture).
