The protocol dictated the use of a gum elastic bougie (GEB) for intubation difficulty, followed by insertion of an intubating laryngeal mask airway (ILMA) if intubation was still not successful. Intubation difficulty was defined as two failed laryngoscopy attempts by a senior physician using optimal laryngeal manipulation. For difficult ventilation, the protocol recommended ILMA insertion follo...

To the Editor:—Dr. Kristensen has concluded that during intubation with the use of a flexible fiberscope, the use of the Parker Flex-Tube results in a significantly lower rate of repositioning and repeated attempts at passing the tube into the trachea, compared to a standard endotracheal tube. We believe it would be more appropriate to conclude that the Parker tube is better only when the stand...
