    Abstract:
    UNLABELLED: Fiberoptic bronchoscopy (FOB) has become a commonplace procedure in ICUs in patients after operation. We studied the outcomes of 35 FOBs performed in 26 patients (18 male and 8 female) during their stay in the ICU of "St. Ekaterina" University Hospital in Sofia after cardiac surgery with Cardiopulmonary Bypass. 33 (95%) of our patients were receiving mechanical ventilation at the time of the FOB. Bronchoalveolar lavage (BAL) was added to all procedures. 21 (60%) patients demonstrated an improvement after FOB. We defined improvement as either an increase of PaO2 with 10 or more mmHg in 6 hours after the procedure or better aeration on the follow-up chest radiograph (CXR). In 19 (54%) FOBs a great amount of secretions, plugging up bronchial lumens was seen. 14 (73%) of these patients were improved after the FOB. From the rest 16 patients, in whom such increased amount of secretions was not seen on FOB, only 7 (43%) demonstrated an improvement after the FOB. 16 procedures were performed on indications of atelectasis. 9 (56%) of them showed an improvement after the FOB. When atelectasis was not present on the CXR, an improvement was found in 12 (63%) cases. CONCLUSIONS: 1. FOB is most effective in removing retained secretions. 2. Although not so effective in resolving atelectasis that is not caused by central plugging, FOB should not be neglected because of the additional benefit of BAL for clearing more distal airways.
