Objectives: Impact of COVID 19 pandemic changed approach to open airway procedures. In our study we want to retrospectively evaluate bronchoscopic interventions and COVID 19 infection risk after bronchoscopic evaluations under suggested precautions in a referrance hospital.

Material and Methods: 664 bronchoscopy procedure done in our hospitals bronchoscopy unit unit between April 25th 2020- July 25th 2020 were retrospectively evaluated.

Results: 661 procedure were done to 604 patients (mean age 57.43±14,49; 70,4% male). 552 (91,4%) of the patients have undergone only one bronchoscopy but for others repeated bronchoscopies were done. Before the procedure, at least one COVID‐19 PCR test via oropharyngeal/nasopharyngeal swab was performed (97,3%) of the 643 procedures. 447 (67,9%) fiberoptic bronchoscopy, 127 (18,8%) convex probe endobronchial ultrasound, and 87 (13.3%) rijid bronchoscopy were applied. During this 3 month time 36 pulmonologist, 10 nurse and 6 staf take part in these 661 prosedure. A total of 14.20±9.41 (1-36; IQR 12) prosedure per pulmonologist were done. No complaint was seen in any of the staf after 14 days of follow up. From 604 patients only for 54 of the patients PCR evaluation was done in the 14 days period (mean time 7.75±4.07(1-14). From 54 PCR only 3 (5,6%) resulted positive and have undergone treatment for COVID 19.

Conclusion: Pretesting before bronchoscopy and adhering protected measures as much as possible is ideal to protect health care workers and other sensitive patients.
