Abstract

Purpose: Sonography has become available for use during flexible bronchoscopy. Reports on useful applications are based on data acquired during examinations in general anesthesia mainly. When used in local anesthesia, what obstacles are encountered? Method: Since July 2000 extraluminal masses evident radiologically and/or endoscopically were investigated during 119 EBUS examinations. All records were reviewed for complications, side effects and quality of information obtained. Results: Unsatisfactory images due to insufficient coupling was recorded in 3 cases. 7 examinations had to be terminated prematurely, 5 for technical reasons, 2 for uncooperative patients. Prior to each examination preparation of equipment added 10 minutes of technician time, average prolongation of bronchoscopy was recorded as 12 minutes. The following were particularly time consuming: continuous probe movement due to coughing and respiratory movements, foamy secretions impairing visibility and alignment of EBUS with the endoscopic picture. Notable desaturation was recorded in 8% of patients, significant coughing prolonging the procedure was present in 12%. Balloon rupture occurred 7 times due to rotatory compression by the endoscope. Conclusion: EBUS in local anesthesia increases examination costs and duration.
