Percutaneous tracheostomy is routinely performed in most intensive care units in the world.Several studies have shown that the procedure is safe and economically efficient in comparison to open surgical operation in the operating room. In the investigator's institution as in a number of institutions in the country and abroad, it is acceptable to perform the operation either by withdrawing the endotracheal tube to a position near the vocal cords by direct laryngoscopy and then puncturing the trachea with a needle distal to the endotracheal tube, prior to carrying out the PDT, by location of the anatomy by palpation of the neck, or alternatively by doing the entire procedure under bronchoscopic guidance. So far, no systematic comparison has been made between the two methods ie PDT without bronchoscopy versus PDT with bronchoscopy.
