LMA CTrach™ in patients with anticipated difficult airway: A retrospective study

LMA CTrach™, a newer airway conduit, with its ability to ventilate and intubate is the ideal device for airway management for difficult airways. A retrospective study was conducted to evaluate the efficacy of this airway device in patients with anticipated difficult airway. 250 patients in whom LMA CTrach™ was used for endotracheal intubation was analyzed. These patients were analyzed for anticipated difficult airway, success rate of intubation with LMA CTrach™, difficulties encountered and corrective measures applied. Fifty five patients had predictors of difficult airway and LMA CTrach™ was successful in all but one. Although successful intubation was achieved with LMA CTrach™, difficulty in intubation was encountered in six patients. This could be overcome with excessive pressure, correctional manoeuvers or a larger size LMA CTrach™. The most common predictors of difficult airway encountered were Modified Mallampati class 3, restricted extension, restricted mouth opening of two finger breadths and retrognathia. LMA CTrach™ is a useful airway device in a difficult airway scenario with the ability to ventilate and intubate the patient.
