Number Of Patients

In order to assess the availability of appropriate resources for a programme of in-theatre teaching of airway skills using anaesthetised patients, two surveys of airway management on anaesthetised patients with identification of those suitable for teaching airway care; and a questionnaire to senior anaesthetists assessing attitudes to such teaching were performed. The results demonstrated that, of all patients undergoing general anaesthesia 45% were intubated and of these 29% were regarded as suitable for teaching intubation. The introduction of the Laryngeal Mask Airway (LMA) into clinical practice has reduced the number of patients having their airways maintained by either bag and mask or tracheal intubation, with implications for learning those skills. In our survey 16% had a Laryngeal Mask Airway (LMA) placed for airway securement and of these 29% would have been intubated had the LMA not been available. Finally, amongst anaesthetists in our survey there is a wide variety of attitudes to teaching airway skills using anaesthetised patients.

Intubating Laryngeal Mask Airway

Background The intubating laryngeal mask airway (ILMA; Fastrach; Laryngeal Mask Company, Henley-on-Thames, UK) may provide an alternative technique to fiberoptic intubation (FIB) to facilitate the management of the anticipated difficult airway. The authors therefore compared the effectiveness of the ILMA with FIB in patients with anticipated difficult intubation. Methods One hundred patients, with at least one difficult intubation criteria (Mallampati class III or IV, thyromental distance < 65 mm, interincisor distance < 35 mm) were enrolled (FIB group, n = 49; ILMA group, n = 51) in this prospective randomized study. Anesthesia was induced with propofol and maintained with alfentanil and propofol after an efficient mask ventilation has been demonstrated. The success of the technique (within three attempts), the number of attempts, duration of the successful attempt, and adverse events (oxygen saturation < 90%, bleeding) were recorded. Results The rate of successful tracheal intubation with ILMA was 94% and comparable with FIB (92%). The number of attempts and the time to succeed were not significantly different between groups. In case of failure of the first technique, the alternative technique always succeeded. Failures in FIB group were related to oxygen desaturation (oxygen saturation < 90%) and bleeding, and to previous cervical radiotherapy in the ILMA group. Adverse events occurred significantly more frequently in FIB group than in ILMA group (18 vs. 0%, P < 0.05). Conclusion The authors obtained a high success rate and comparable duration of tracheal intubation with ILMA and FIB techniques. In patients with previous cervical radiotherapy, the use of ILMA cannot be recommended. Nevertheless, the use of the ILMA was associated with fewer adverse events.
