Comparison between nasopharyngeal airway and laryngeal mask airway in blepharoplasty under general anaesthesia. A randomized controlled trial.
Trial report in Anaesthesiology intensive therapy, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
introductionBlepharoplasty can be performed under local infiltration anaesthesia with or without sedation or general anaesthesia depending upon the surgical plan, patient and surgeon preferences, and duration of surgery. Securing the airway with an endotracheal tube or a laryngeal mask airway may cause sore throat. The primary aim of our study was to compare the incidence of this complication between the nasopharyngeal and laryngeal mask airways among patients receiving general anaesthesia during blepha-roplasty. MATERIAL AND
methodsOne hundred forty-eight patients (40-60 years old), ASA II-III, were randomly and evenly assigned to one of two groups. After induction of general anaesthesia, a nasopharyngeal airway or a laryngeal mask airway was inserted according to group allocation. All patients received local infiltration anaesthesia given by the surgeon. Haemodynamic variables, oxygen saturation, end-tidal CO2, failure rate and recovery time were monitored. Postoperative complications (mainly sore throat) as well as patients' and surgeon's satisfaction, were recorded.
resultsCompared to laryngeal mask airways, the use of nasopharyngeal airways was associated with significantly lower incidence of sore throat (4.0% vs. 17.6% with a difference of 13.5%, 95% CI [3.5-24.1%], P < 0.015), shorter recovery times (10.3 min ± 2.84 min vs. 12.6 min ± 2.65 min, P < 0.001), and better patient and surgeon satisfaction (P < 0.001 for both).
conclusionsNasopharyngeal airways are an excellent alternative to laryngeal mask airways in anaesthetizing patients undergoing four-lid blepharoplasty surgery, with shorter recovery time, less incidence of postoperative sore throat and better patients' and surgeon's satisfaction.
