title: [Rational fiberoptic bronchoscopy under local analgesia].
abstract: Bronchoscopy with the fibre bronchoscope under local analgesia influences circulatory and pulmonary function, depending partly on the form of premedication employed, anticholinergic preparations, the local analgesic and the form of application. Physiological and pharmacological knowledge is available on which a rational choice of the method of examination may be based. In order to reduce untoward sequelae of the examination, the following are recommended: avoidance of sedative premedication, which appears to be unnecessary, administration of supplementary oxygen during and for at least two hours after the examination (special care is required in cases of chronic hypercapnia) and employment of anticholinergic preparations, particularly in asthmatic patients. Nevertheless, slight degrees of bronchoconstriction may be anticipated during and after the examination. Examination via an endotracheal tube is warned against in patients with respiratory difficulties. There is much to recommend the choice of lidocaine as the routine analgesic and this is administered in the form of inhalation from an atomizer. On the basis of absorption investigations, the dosage may probably be raised to approximately 7 mg/kg. Patients with cardiac and liver disease have, however, reduced distribution volumes and clearance.
