研究概览

简要总结

Double lumen tubes(DLT) and bronchial blockers (BBs) have  traditionally been used for one lung ventilation. While insertion of DLT is technically difficult; BBs have been easier to use, but they require frequent repositioning.Blockers also cause less intubation related post-operative complications (sore thro at, hoarseness of voice) and negate the need to change the DLT to a single lumen tube at the end of surgery.Fibre optic bronchoscopy is recommended to confirm the correct placement; more so, for the DLT owing to its larger lumen. EZ blocker is a semi-rigid catheter with two distal extensions, inflatable balloons and anchors itself on the carina. It is hypothesised to be easier to introduce than DLT, even without an FOB aid. The aim of our study is to assess the safety and efficacy of inserting this novel blocker without use of FOB and compare it with DLT insertion with similar technique.
