Abstract

LMA CTrachTM, 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 CTrachTM was used for endotracheal intubation was analyzed. These patients were analyzed for anticipated difficult airway,success rate of intubation with LMA CTrachTM, difficulties encountered and corrective measures applied. Fifty five patients had predictors of difficult airway and LMA CTrachTM was successful in all but one. Although successful intubation was achieved with LMA CTrachTM, difficulty in intubation was encountered in six patients. This could be overcome with excessive pressure, correctional manoeuvers or a larger size LMA CTrachTM. 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 CTrachTM is a useful airway device in a difficult airway scenario with the ability to ventilate and intubate the patient.
