Clinical desaturation could be present during diagnosis/therapeutical procedures using flexible fiberbronchoscopy FBC. The use of additional oxygen is subjet to great variations both withing and between countries. The role of geographical altitude during FBC and the indication of additional oxygen support has not been well defined.To evaluate at 1951 meters above sea level the incidence of additional oxygen support and the main indication during FBC at 5 differents community hospitals.
Consecutive patients who underwent FB were prospectively evaluated. Epidemiological data, indications and oxygen saturation was monitored before, during and after procedure and recorded at 5 different intervals: a) in supine position,b) through nasal/oral route until epiglotis, c) during tracheal evaluation, d) diagnostic/therapeutical procedure, e) at any moment when desaturation was detected.
83 patients were enrolled but 3 excluded because domiciliary oxygen support. FBC was performed transnasally (97%), 100% of p presented an episode of desaturation <90% for a period <30 seg. 35/80p, received additional oxygen support during FBC: nasal catheter (5/14.3%), face mask (22/62.8%), ventury mask (2/5.7%) and non invasive mechanical ventilation (6/17.1%).
Despite high altitude, in The Morelia multicentric experience, the use of additional oxygen support to all population is not mandatory during FBC.
The rational use of additional oxygen support could be elegible to those population who really need it, with potential economical impact.
