Comparison of LMA Protector vs. endotracheal tube in patients undergoing laparoscopic surgery: a randomised controlled trial.
Trial report in Anaesthesiology intensive therapy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled it.
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
introductionRecent advances in airway management have led to supraglottic airway devices (SAD) being increasingly often chosen instead of tracheal intubation for laparoscopic surgery. However, there are ongoing arguments regarding the use of SAD due to worries about the risks of insufficient ventilation and pulmonary aspiration. The LMA Protector is a second generation SAD which was put into use recently. This prospective randomised trial investigated whether the LMA Protector was comparable to the tracheal tube regarding respiratory parameters, perioperative complications and haemodynamic parameters in patients undergoing laparoscopic surgery. MATERIAL AND
methodsA total of 154 adult patients were randomised to two groups: Group 1 (tracheal intubation) and Group 2 (LMA Protector). Achieving adequate depth of anaesthesia, the patients were either intubated or the LMA Protector was placed. The initial baseline measurements were recorded including tidal volume, peak inspiratory pressure (PIP), oropharyngeal leak pressure (OLP) and haemodynamic parameters. These measurements were repeated and recorded again following pneumoperitoneum and recovery from anaesthesia.
resultsAt the mean age of 52.22 ± 13.90 years 77 patients were intubated and in 77 patients the LMA Protector was applied. Following insertion of the airway device and pneumoperitoneum, the heart rate was higher in the intubation group. In the LMA Protector group OLP measures were found to be statistically similar. The mean Brimacombe fibreoptic visualisation score was 2.12 ± 0.58 and the rate of requirement of optimisation was 15% in the LMA Protector group.
conclusionsWith high OLP, better haemodynamic parameters and low laryngeal view scores, we concluded that the LMA Protector can be used safely in patients undergoing laparoscopic surgery.
