Abstract
Background and Aims:
Primary aim of the study was to evaluate the performance of Intubating LMA (ILMA) and blockbuster LMA in terms of first pass success rate, ease and duration taken for blind tracheal intubation.
Material and Methods:
The present prospective randomised study was conducted on 70 patients of either sex aged 18-60 years belonging to ASA physical status I or II. Patients were randomly allocated to either, group I and group B of n = 35 each. In group I and B patients were intubated using ILMA and LMA BlockBuster respectively. Insertion time and ease of placement of supraglottic device, total time taken for successful intubation, number of attempts for endotracheal tube (ETT) placement, and ease of placement of ETT, were recorded.
Results:
In both groups, the supraglottic device was placed on the first attempt in 88.6% patients. The first-attempt success rate for ETT placement was 71.4% in group I versus 94.3% in group B, (P = 0.01) with an overall success rate of 88.5% in group I and 100% in group. More failure rate was observed in group I (11.4%) compared to group B (0%). The total time taken for successful intubation in group I was 11.53 ± 6.410 sec and 9.17 ± 2.749 sec in group B (P = 0.04).
Conclusion:
We conclude that the modifications in the design of LMA Blockbuster (>95° angle, availability of the parker flex tube 27–30°angle of the emergence of airway tube) make it a more convenient, effective, simpler, and faster intubating device than ILMA.
