Bronchoscopy is an endoscopic technique of visualizing the inside of the airways for diagnostic and therapeutic purposes. An instrument ( bronchoscope ) is inserted into the airways, usually through the nose or mouth, or occasionally through a tracheostomy .
Bronchoscopy with bronchoalveolar lavage is recommended in possible cases of organizing pneumonia to rule out infection and other causes of alveolar infiltrates. [9] The bronchoalveolar lavage in organizing pneumonia shows a lymphocytic predominant inflammation of the alveoli with increases in neutrophils and eosinophils. [9]
Treatment of unconscious patients focuses on preventing or treating obstructions of the airway, such as head-tilt/chin-lift and jaw-thrust maneuvers, while the use of the recovery position mainly prevents aspiration of things like stomach content or blood.
Any approach to lung biopsy risks causing a pneumothorax.Careful technique can limit this risk, which ranges from less than 1% to about 10%. The precise risk of pneumothorax depends on technique and on underlying lung disease, as certain lung diseases such as COPD can increase the risk of pneumothorax.
In contrast to supraglottic devices, infraglottic devices create a conduit between the mouth, passing through the glottis, and into the trachea. There are many infraglottic methods available and the chosen technique is reliant on the accessibility of medical equipment, competence of the clinician and the patient's injury or disease.
The treatment has been shown in prospective studies to be safe and effective with duration up to five years. [5] Bronchial thermoplasty is indicated for the treatment of severe persistent asthma in patients 18 years and older whose asthma is not well controlled with inhaled corticosteroids and long acting beta agonists as per guidelines of the ...
