Confirmation of double lumen tube placement with thoracic USG in thoracic surgery operations with one LUNG ventilation

BACKGROUND: The aim of this study is to evaluate the confirmation of double lumen tube placement with thoracic USG in thoracic surgery operations with one lung ventilation. METHODS: In this prospective and observational study, 130 patients aged between 18-65 years in ASA (American Society of Anesthesiology) I-III risk class who will undergo thoracic surgery with the application of single-lung ventilation were included in the study. A double-lumen endobronchial tube was placed in the patients blindly. One-lung ventilation was confirmed by thoracic USG by the anesthesiologist. The patient's demographic data, rapid clinical evaluation and USG data results, and intraoperative surgeon satisfaction were recorded. RESULTS: The success of estimating DLT position with thorax USG was found to be statistically significant when compared with other methods (p=<0.001). The sensitivity and specificity values ​​of DLT position success estimation of fiberoptic bronchoscopy were found to be higher than other methods. BMI was found to be higher in patients with failed USG and rapid clinical evuluation estimation of DLT position (p<0.001). CONCLUSİONS: The results of this study showed that thoracic USG can be used as an alternative to rapid clinical evaluation method in thoracic surgery patients undergoing one lung ventilation.
