Lasers in pulmonology.

ABSTRACT

Lasers have multiple applications in pulmonary medicine. The Nd Yag laser is at present widely accepted for the management of respiratory problems. The major indications are central tracheobronchial obstruction due to neoplasms, uncontrolled haemorrhage from malignant lesions and tracheal stenosis. Its role is entirely palliative and only occasionally curative. Two main complications are perforation and bleeding. The basic concepts, techniques and use in various respiratory problems are discussed.
