Coughing on insertion, free aspiration of air through a syringe containing saline, the presence of a palpable flow of air through the cannula on exhalation and capnography confirmed its position. After infiltration of local anaesthetic, a 13G Ravussin cannula (VBM GmBh, Sulz, Germany) was placed in the trachea through the cricothyroid membrane, at the second attempt. Fibreoptic confirmation of Ravussin cannula position was to be omitted because of previous difficulty.ĭifficult airway equipment was assembled in theatre. Transtracheal jet ventilation, anaesthesia and surgery were then uneventful.įor this operation it was again anticipated that the trachea would be impossible to intubate conventionally and the consultant anaesthetist intended to follow the former anaesthetic plan. An attempt was made to perform awake fibreoptic confirmation of the position of the cannula via the anaesthetised nose prior to transtracheal jet ventilation but this failed due to narrow nasal passages and multiple nasal polyps. On the second occasion, a Ravussin cannula was placed through the cricothyroid membrane before anaesthesia. On the first occasion, induction had been followed by failed intubation and failed ventilation leading to profound hypoxia, which resolved when spontaneous ventilation resumed during attempts to perform needle cricothyroidotomy. The patient had been anaesthetised twice in the previous six months, on both occasions by a consultant anaesthetist.

Airway assessment revealed a full set of teeth in poor condition, mouth opening reduced to 2 cm ( 2, 3), a modified Mallampati class 4 oropharyngeal view, a thyromental distance of 7 cm and a sternomental distance of 8 cm. This and ankylosing spondylosis resulted in a complete lack of neck extension ( Fig. 1).

Previous radiotherapy was complicated by infection and sloughing off of the skin and subcutaneous tissues of the neck and the anterior neck was grossly scarred. He was admitted for surgical laryngoscopy with a view to laser resection of a suspected epiglottic recurrence. Nasendoscopy revealed a 2-cm epiglottic mass. Case reportĪ 52-year-old man with a history of laryngeal carcinoma presented to his ENT surgeon with a change in his voice. The report demonstrates novel applications of the LMA Proseal ™ (Intavent, Maidenhead, UK) and Aintree intubation catheter ® (Cook Critical Care, Letchworth, UK) as airway ‘rescue’ devices and illustrates important complications of blind insertion of a cricothyroidotomy cannula and transtracheal jet ventilation. We report our management of a patient with a known ‘difficult airway’ and a history of failed intubation and ventilation during a previous anaesthetic. Complications of transtracheal jet ventilation as well as possible methods for avoiding them are also reviewed. Novel roles of the Aintree intubation catheter and LMA Proseal in this case are discussed.

This was achieved using the Aintree intubation catheter as an aid to nasal fibreoptic intubation and as a tube exchanger. Some hours after the procedure, re-intubation was necessary.

Fibreoptic placement of an Aintree intubation catheter ® through this allowed re-oxygenation and exchange for a cuffed tracheal tube. The airway was re-established by insertion of an LMA Proseal ™. Upper airway obstruction developed during the procedure, preventing exhalation, which led to raised intrathoracic pressure, cardiovascular collapse and barotrauma. Nevertheless, a cricothyroid catheter was placed and surgery performed during low frequency ‘volume’ jet ventilation. Neck scarring potentially complicated access for transtracheal jet ventilation. During a previous anaesthetic the patient had been both ‘impossible to intubate and to ventilate’. Previous attempts at tracheal intubation and awake nasal fibreoptic intubation had failed. We report the management of a patient requiring surgical laryngoscopy with a view to laser resection of an epiglottic recurrence of laryngeal cancer.
