“…Flexible bronchoscopy (FB) is a valuable technique in the approach to pulmonary disorders, and plays an important role in the management of critical care patients. It is used for both diagnostic and therapeutic purposes, such as identification of microbiological agents, determining the source of hemoptysis, removal of foreign bodies or secretions that cause atelectasis, selective intubation, or visual support during percutaneous tracheostomy [1][2][3][4] .…”

SUMMARY Flexible bronchoscopy (FB) plays an important role in critical care patients. But, critical care patients with respiratory failure are at an increased risk of developing complications. Considering the developments in intensive care unit care in recent years, we aimed to evaluate the use of FB in these patients. We retrospectively reviewed patients who underwent FB in critical care between 2014 and 2020. A total of 143 patients underwent FB during the study period. Arterial blood gas measurement on the FB day revealed a mean PaO 2 /FiO 2 of 186.94±28.47. Eighty-one (56.6%) patients underwent an fiberoptic bronchoscopy procedure under conventional oxygen supplementation, 10 (7%) on noninvasive ventilation, 13 (9.1%) on high flow nasal cannula, and 39 (27.3%) on invasive mechanical ventilation. During and immediately after bronchoscopy, none of the patients experienced life-threatening complications. Fifty-five (38.5%) patients developed complications that could be controlled. Multivariate analysis indicated that increased Apache-II score and presence of cardiovascular disease were significantly associated with an increased complication risk. Although critical care patients with respiratory failure are more prone to complications, diagnostic and therapeutic bronchoscopy may be performed following appropriate patient selection, without leading to major complications.

Introduction: The size of the changes is important for determining the invasiveness of the process and the stage of development of the neoplastic processes of the lung. The use of the method of virtual bronchoscopy as a diagnostic method in central lung carcinoma provides non-invasive visualization, but also abilities to measure changes. Purpose: The study aims to present the results of the application of the VB method in determining the size of the changes in patients with central lung carcinoma. Methods: 130 patients, diagnosed with central carcinoma, went VB method, using 64 MDCT Siemens Definition AS. The criteria size of the changes in different localization (right or left) and sex (women, men) was considered in the work. Results: 98 men and 32 women, aged 26-83 years, diagnosed with central lung cancer were examined using the method of virtual bronchoscopy, in which the size of the changes was monitored. In central right carcinoma of men, the formations in CT ranged in average from 5 to 68 mm (36.5 ± 18.62) and the largest number of findings were of 21–43 mm (44.5 ± 14) in length. The length of the changes in men with central left carcinoma ranged from 0.45 mm to 31 mm (12.7 ± 10.59). The length of the changes in women with central right carcinoma was from 0.44 to 1.86 mm (6.45 ± 6.83), and in those with left localization - from 0.6 to 13.1 mm (10.35 ± 6.74). In men, all six groups of stenoses were presented, most of them with sizes over 20 mm, followed by those with sizes below 3 mm. In women, stenoses were presented in only 3 groups, most of which were less than 3 mm in size. A significant relation was found between the sex of the studied patients with central carcinoma and the length of the stenoses. Sex was a determining factor for the length of the stenoses (χ2 = 212.77, p = 0.0000). Conclusions: Virtual bronchoscopy allows accurate metry in all planes. The magnitude of the measured changes is important for determining the invasiveness of the process. The results obtained in VB should always be interpreted with axial and multiplanar images.
