Sir,

We were intrigued by the successful management of an anticipated difficult airway in a patient with severe cervical spine pathology by Koyama et al.[1] using fluoroscopy guided technique. We congratulate the authors for their novel outlook and successful execution of endotracheal intubation in a patient with difficult airway.

We would like to raise a few concerns regarding the above stated novel technique. Firstly, we could not identify the author's back up plans in case of failure of the primary plan. All current airway management guidelines stress on meticulous planning for a difficult airway including backup plans commonly known as plan B and C.[2],[3] It would be prudent to have these plans handy especially when the primary plan is novel and not commonly used. Secondly, authors have shown use of lateral fluoroscopic view showing sagittal section of the airway which can easily differentiate trachea from oesophagus. When the sagittal view is not accompanied by a simultaneous frontal view in coronal plane, it is difficult to avoid the potential risk of the bougie going laterally leading to trauma and disastrous bleeding.

Radiologic-Assisted Endotracheal Intubation by Reier et al.[4] was done in an awake patient. Safety margin is high in an awake patient since the patient can take care of own airway. Subjecting sedated patient to such uncommon methods involves greater risk especially when safer alternatives are available.

It may be prudent to use this novel technique in simulations, models or non-difficult airway cases before using it in a difficult airway case. Similarly, it may be ethically appropriate to use an established technique in a difficult airway situation rather than subjecting the patient to the uncertainty of a novel technique.

As authors mention the insertion of LMA, we would be interested in knowing if the authors considered using established alternatives like fibreoptic bronchoscopy through supraglottic airway device using Aintree intubation catheter or simply an intubating LMA. Wong et al.[5] in their review have described various techniques of achieving endotracheal intubation through supraglottic airway devices. A modified version of Intubating LMA known as LMA C trach also can be used in such a situation.

In conclusion, we appreciate the author's novel technique for management of a difficult airway scenario, but at the same time reassert the importance of planning, patient safety, understanding limitations of novel techniques and ethics while using these novel techniques.
