The aim of this study is to evaluate the positioning time and the malpositioning rate of DLTs and BBs, the degree of difficulty perceived in device positioning, the use of bronchoscopy (BRO), and the quality of lung collapse achieved during ONE LUNG VENTILATION.
Safety and efficacy of the double-lumen tubes (DLT) and bronchial blockers (BB) for lung isolation in patients undergoing thoracic surgery have been extensively studied and most of the results show similar rates of successful placement and lung collapse. DLT and BB are more frequently inserted by anesthetists who are expert in thoracic anesthesia, with dedicated but different training.
The first objective of this study was to evaluate the positioning time and the malpositioning rate of DLTs and BBs, the degree of difficulty perceived in device positioning, the use of bronchoscopy (BRO), and the quality of lung collapse achieved during OLV.
A prospective observational study was designed. To check the optimal DLT (Broncho-Cath Covidien, Ireland, Dublin, Teleflex Medical, Athlone, Irelanad) and/or BB (Uniblocker, Phycon, Fuji, Japan Arndt Cohen Cook, Australia), placement a fiberoptic bronchoscope (FOB) was used. The lung collapse was assessed by surgeons.
Time from laringoscopy to the correct placement of the device, confirmed with FOB, was checked.
Data were analyzed with Student't Test and Chi-square test; p value \< 0.05 was considered to be significant.
Azienda Ospedaliera S. Maria della Misericordia is the lead sponsor of 7 studies on the registry; none are open to participants now.

DOUBLE LUMEN TUBE AND BRONCHIAL BLOCKER POSITIONING SUCCESS RATE: RESIDENTS vs. ATTENDING ANESTHETISTS.
A prospective randomized trial was designed. To check the optimal DLT (Broncho-Cath Covidien, Ireland, Dublin, Teleflex Medical, Athlone, Irelanad) and/or BB (Uniblocker, Phycon, Fuji, Japan Arndt Cohen Cook, Australia), placement a fiberoptic bronchoscope (FOB) was used.
