Clinical Performance of the BlockBuster Laryngeal Mask Airway for Blind Endotracheal Intubation in Adult Elective Surgeries: A Prospective Observational Study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionEffective airway management is central to safe anesthesia practice. While endotracheal intubation remains the gold standard, supraglottic airway devices (SGADs) provide less invasive alternatives. The BlockBuster® Laryngeal Mask Airway (BBLMA) has been designed to facilitate blind endotracheal intubation while maintaining a secure airway. However, data on its performance in Indian patients are limited. MATERIALS AND
methodsThis prospective study was conducted on 60 ASA I-II adult patients undergoing elective surgery under general anesthesia at Sree Balaji Medical College and Hospital, Chennai (August 2024-August 2025). Following standard induction, the BBLMA was used as a conduit for blind intubation. The success rate, time required for intubation, ease of intubation, and hemodynamic parameters were recorded. Data were analyzed using R software. Repeated-measures ANOVA and appropriate univariate tests were applied, with a significance level of p< 0.05.
resultsSuccessful intubation through BBLMA was achieved in 58 of 60 patients (96.7%). Most intubations (76.7%) were graded as easy, with a mean intubation time of five minutes and 15 seconds. Hemodynamic parameters (systolic BP, diastolic BP, heart rate) showed statistically significant increases following insertion and intubation, although all remained within clinically acceptable limits.
conclusionThe BBLMA demonstrated high success, ease of use, and hemodynamic stability during blind endotracheal intubation. These findings suggest that BBLMA can be safely considered as a first-line airway device for elective and potentially emergency anesthesia settings.
