Laryngeal mask airway improves hemodynamics and reduces pharyngeal discomfort in total joint arthroplasty.
Trial report in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Endotracheal intubation (EI) can adversely affect hemodynamics and patient satisfaction. Concerns regarding the safety of the laryngeal mask airway (LMA) in total joint arthroplasty (TJA) arise from patient positioning and the surgical procedure. This study aimed to compare the effects of EI and LMA on hemodynamics and postoperative pharyngeal discomfort in TJA, and evaluate LMA's safety. In this prospective trial, 100 patients undergoing TJA due to end-stage joint disease at our medical center between August 2023 and August 2024 were enrolled. Following the induction of anesthesia, patients were randomly assigned to either EI or LMA. Postoperative sore throat and hoarseness were assessed upon awakening and at 6, 24, and 48 h. The primary outcome was postoperative pharyngeal discomfort; secondary outcomes were hemodynamic stability and airway complications. At 6 h post-TJA, sore throat (32% vs 12%, P = 0.030) and hoarseness (70% vs 36%, P = 0.003) were significantly lower in the LMA group. At 24 h, hoarseness remained lower (22% vs 6%; P = 0.021). The incidence of hemodynamic instability during airway establishment (40% vs 4%, P < 0.001), removal (78% vs 24%, P < 0.001), and during TJA (62% vs 14%, P < 0.001) was significantly lower in the LMA group. No significant differences in airway complications were found. LMA use in TJA reduced postoperative pharyngeal discomfort and improved hemodynamic stability, making it a safe and effective alternative to EI.
