Alkalized lidocaine in a tapered cuff suppresses endotracheal tube-induced hemodynamic changes: a randomized controlled trial.
Trial report in Journal of anesthesia, 2023. 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
purposeThe use of an endotracheal tube (ET) cuff filled with alkalized lidocaine (AL) can suppress ET-induced emergence phenomena, such as hypertension, tachycardia and coughing, and postoperative sore throat (POST) and hoarseness (PH). The efficacy of intracuff lidocaine may vary depending on the cuff shape, but there has been no study on the effects of a tapered cuff filled with AL. We examined whether intracuff AL suppresses ET-induced emergence phenomena, POST and PH.
methodsSixty-two patients were enrolled in this study and the patients were randomly allocated to a group in which the tapered cuff was filled with AL (Group AL) and a group in which the tapered cuff was filled with normal saline (Group S). The primary outcomes of this study were changes in mean blood pressure (MBP) and heart rate (HR) at extubation. MBP, HR and the number of coughs were recorded before and up to 10 min after extubation. The degree of POST and the incidences of POST and PH were recorded at 15 min, 2 h and 24 h after extubation.
resultsChanges in MBP before extubation and HR before and after extubation were significantly lower in Group AL than in Group S (p < 0.025). The number of coughs at extubation and the incidence of PH at 2 h after extubation were significantly lower in Group AL than in Group S (p < 0.0001 and p = 0.014, respectively).
conclusionAL in a tapered cuff significantly suppresses ET-induced cardiovascular changes in MBP and HR.
