Blind Endotracheal Intubation through Intubating Laryngeal Mask Airway: is Chandy Manuever beneficial?

Objective: To investigate the utility of ILMA for blind endotracheal intubation in patients undergoing elective surgery under general anaesthesia applying chandy manuever. Material and methods: In this study 62 patients of American Society of Anaesthesiologist class P1 and P-2 status, of age > 18 yrs of both sex and height of less than 160 cm were included and divided into group A 31 patients with chandy manuever and group B 31 patients (without candy manuever). ILMA was inserted as per standard technique after inducing general anaesthesia. The lubricated endotracheal tube was passed through ILMA. After confirmation of successful endotracheal intubation, ILMA was removed. Ease of mask ventilation, time required for insertion of ILMA, number of attempts required for insertion of ILMA, time required to achieve intubation, number of attempts required for blind endotracheal intubations were recorded. Results: Only one attempt was done for every patient and 90.3% successfully intubation in group A and 58.1% in group B. Conclusion: Blind endotracheal intubation through ILMA is easy with the application of chandy manuever as compared to without this manuever.
