Supraglottic airway devices in awake tracheal intubation: a viable alternative to fiberoptic and video laryngoscopy.
Observational study in BMC anesthesiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06279416 (Evaluation of Advanced Airway Methods Applied to Patients Who Were Awakened Due to Difficult Airway in Another Center or Who Were Predicted to Have Difficult Airway in Preoperative Evaluation), which is not on this map.

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.

Abstract
backgroundAwake tracheal intubation is advised for patients with known difficult airways. While flexible bronchoscopy is the conventional technique, video laryngoscopy offers faster intubation. Recent studies reveal that supraglottic airway devices can also be effectively used for awake intubation; however, few investigations compare their effectiveness with that of flexible bronchoscopy and video laryngoscopy. This study aims to compare the effectiveness of these three. methods: flexible bronchoscopy, video laryngoscopy, and awake tracheal intubation using supraglottic airway devices.
methodsPatients were divided into three groups: fiberoptic bronchoscopy, video laryngoscopy, and supraglottic airway groups. All patients received Sedation with remifentanil and midazolam, Topical anesthesia with inhaled and sprayed lidocaine, Oxygenation with high-flow oxygen therapy, and intubation Performed by the same operator, known as the ‘STOP’ protocol. The primary outcomes encompassed first-attempt success rate, alternative method success rate, and overall success rates. Secondary outcomes included intubation times and procedural complications.
resultsSuccess and complication rates were similar across groups. The supraglottic airway group had a mean vocal cord imaging time of 74.93 ± 55 s, longer than video laryngoscopy but shorter than fiberoptic bronchoscopy. Intubation times were longer for the supraglottic airway group (210.0 ± 120 s) than for video laryngoscopy but shorter than fiberoptic bronchoscopy.
conclusionThe awake supraglottic airway technique offers advantages over traditional awake intubation methods, including the ability to monitor tidal volume and maintain continuous oxygenation throughout the procedure. This technique achieves comparable success rates, intubation times, and complication rates to video laryngoscopy and fiberoptic bronchoscopy, making it a reliable alternative for difficult airways.
