Comparison of Intratracheal Dexmedetomidine versus Lignocaine on Attenuating Emergence Cough Response to Extubation in Patients Undergoing Craniotomy for Intracranial Tumor: A Multi-arm 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
objectiveSmooth extubation is crucial for patients undergoing craniotomy. Multiple drug regimens, administered in different doses and via different routes, have been studied to attenuate the emergence of cough response. However, a direct comparison of their relative efficacy remains lacking. This study aims to compare the effect of intratracheal (IT) dexmedetomidine (DX) and IT lignocaine (LG) on the emergence of coughing and hemodynamic response to extubation in patients undergoing craniotomy.
methodsThis randomized, double-blind, multiarm controlled trial involved patients aged 18-60 years of either sex with an American Society of Anesthesiologists Physical status I or II, who were planned for elective craniotomy due to an intracranial tumor. Participants were randomly divided into three groups, each containing 15 individuals. Group DX received DX, Group LG received LG, and Group normal saline (NS) received NS intratracheally 15 min before extubation. The emergence of cough response was recorded during extubation, and hemodynamic parameters, including heart rate, mean blood pressure, and visual analog scale score, were monitored at different intervals throughout the study. STATISTICAL ANALYSIS AND
resultsA statistically significant difference was noted in the emergence of cough response between the DX and NS groups ( P < 0.05) as well as between the LG and NS groups ( P < 0.05), as determined by pairwise intergroup analysis using the Kruskal - Wallis test followed by Bonferroni post hoc correction. No significant difference in emergence cough scores was found between the DX and LG groups ( P = 0.66).
conclusionsBoth IT DX and IT LG are equally effective in reducing the emergence cough response. However, IT DX offers the additional advantage of reducing the hemodynamic response to extubation and providing postoperative pain relief.
