Blockbuster Laryngeal Mask Airway Versus Endotracheal Tube for Airway Management in Off-Pump Cardiothoracic Surgery: A Randomized Controlled Study.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background and aims The increasing use of supraglottic airway devices has led to a shift in airway management practices. BlockBuster® Laryngeal Mask Airway (BLMA; Henan Tuoren Medical Device Co., Ltd., China) is a newer second-generation device, and its use in prolonged surgeries remains limited. Off-pump cardiothoracic surgeries are conventionally performed using endotracheal intubation, which may be associated with significant haemodynamic responses. Methods This prospective randomized study included 60 adult patients undergoing elective off-pump cardiothoracic surgeries, allocated into two groups of 30 each. Group A had the airway secured using a Blockbuster LMA, and Group B used an endotracheal tube. Time taken to achieve an effective airway, number of attempts, ease of insertion, intraoperative haemodynamic and ventilatory parameters, and post-operative complications were assessed. Results The time taken to achieve effective airway was significantly shorter in Group A compared to Group B (p<0.001). Haemodynamic parameters including heart rate, systolic blood pressure, diastolic blood pressure, and mean arterial pressure were significantly higher in Group B during the immediate period following airway securement (p<0.05). The incidence of post-operative sore throat was significantly higher in the endotracheal tube group (p<0.05). Ventilatory parameters were comparable between the two groups. Conclusion Blockbuster LMA is a suitable alternative to the endotracheal tube for airway management in patients undergoing off-pump cardiothoracic surgery, providing quicker airway establishment, better haemodynamic stability, effective ventilation, and fewer post-operative complications.
