Effect of the new non-inflatable laryngeal mask GMA-Tulip on airway management for lateral total hip arthroplasty in geriatric patients: a randomized controlled trial.

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
backgroundThe supraglottic airway device (SAD) is nowadays widely used as a ventilation device. The GMA-Tulip is a new non-inflatable SAD used to establish short-term artificial airway for general anesthesia or cardiopulmonary resuscitation. In the present study, we compare the clinical performance of the GMA-Tulip and the LMA Supreme for lateral total hip arthroplasty in geriatric patients.
methodsIn 70 anesthetized and paralyzed adult patients, the GMA-Tulip (n = 35) or the LMA Supreme (n = 35) was inserted. The primary outcome was oropharyngeal leak pressure (OLP). The secondary outcomes included the peak airway pressure (PAP), insertion time, insert resistance, number of insertion attempt and manipulations, glottic exposure grading, and incidence of perioperative complications.
resultsThe GMA group had a significantly higher OLP and lower PAP at the 4 measurement points than did the Supreme group (P < 0.05). Compared with that in the supine position, the OLP of the two groups was significantly lower in the lateral position (P < 0.05). The LMA Supreme had a longer insert time (36(32,39) vs. 18(15,22) sec; P < 0.001) and was inserted more difficultly (P < 0.05). The sore throat scores one hour after surgery at the LMA Supreme was higher than that at the GMA-Tulip (P < 0.05), but the incidence of blood staining was not different between the two groups (P = 0.106).
conclusionsThe GMA-Tulip and LMA Supreme both provided considerable ventilation efficiency during lateral total hip arthroplasty in geriatric patients. Our data showed that new non-inflatable laryngeal mask GMA-Tulip has a higher OLP and demonstrated a shorter time to successful placement and a lower sore throat score one hour after surgery compared with the LMA Supreme.
trial registrationThe trial was retrospectively registered on August 30, 2024 in the Chinese Clinical Trial Registry, registration number ChiCTR2400088996 (30/08/2024).
