BACKGROUND: Airway management plays a key role in day to day anesthesia practice. But unanticipated difficult airway and unnecessary pressor response to laryngoscopy and intubation remains a challenge to the anesthesiologist. A continuous effort has been made to develop new methods and tools to facilitate endotracheal intubation and minimize pressor response. One such device was Laryngeal Mask Airway (LMA). However, the use of LMA was associated with problems like gastric insufflation, pulmonary aspiration, inadequate ventilation and the inability to generate high inflation pressures in bronchospastic patients. Hence ILMA was introduced as an alternative. METHODS: In this prospective study, the feasibility of Intubating Laryngeal Mask Airway (ILMA) insertion and blind endotracheal intubation through ILMA was done in 100 patients undergoing various elective surgeries under general anesthesia. Only ASA Grade I and II patients with normal airway (Mallampati Class I and II) were selected. After administering conventional general anaesthesia, ILMA was inserted as per the standard technique. Blind endotracheal intubation was done through ILMA. Time required for insertion of ILMA, number of attempts required, time duration to achieve intubation and number of attempts for blind endotracheal intubation were recorded. RESULTS: Our study showed that ILMA was inserted successfully in all patients, 91% required one attempt and 9% required 2 attempts. The mean time duration for successful ILMA placement was 33.47 secs. Blind endotracheal intubation through ILMA was possible in 97% of patients, 75% required 1 attempt, 18% required 2 attempts and 4% required 3 attempts. The mean time duration for blind endotracheal tube insertion was 21.74+6.98 secs. CONCLUSION: Thus from our study it can be concluded that ILMA can be used as a blind intubation guide with a higher success rate.

“…Each of the investigators had received training in use of the device by the inventor of the ILMA, and had experience of its use in normal airways. This expertise may help to explain the low success rates with the same technique in our study as proficiency in the use of the ILMA may require 20 attempts [20].…”

Manikin study of fibreoptic‐guided intubation through the classic laryngeal mask airway with the Aintree intubating catheter vs the intubating laryngeal mask airway in the simulated difficult airway*

2010

In this randomised crossover manikin study of simulated difficult intubation, 26 anaesthetists attempted to intubate the trachea using two fibreoptic-guided techniques: via a classic laryngeal mask airway using an Aintree intubating catheter and via an intubating laryngeal mask airway using its tracheal tube. Successful intubation was the primary endpoint, which was completed successfully in all 26 cases using the former technique, and in 5 of 26 cases using the latter (p < 0.0001). The former technique also proved quicker to reach the vocal cords with the fibrescope (median (IQR . We conclude that in simulated difficult intubation, fibreoptic intubation appears easier to achieve using a classic laryngeal mask airway and an Aintree intubating catheter than through an intubating laryngeal mask airway.
