Effect of Atracurium versus Cisatracurium on QT interval changes in patients undergoing cataract surgery: a randomized clinical trial.
Trial report in BMC anesthesiology, 2024. 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
backgroundMuscle relaxants are used during surgery, but their impact on ECG may differ, potentially affecting cardiac safety. This study aimed to compare the effects of Atracurium versus Cisatracurium on QT interval changes in patients undergoing cataract surgery.
methodThis double-blind, parallel-group randomized clinical trial (RCT) was conducted in 2023 in Hamadan, Iran. A total of 80 patients undergoing cataract surgery under general anesthesia were randomly assigned to receive either Atracurium (n = 40) or Cisatracurium (n = 40). QT interval changes were measured at four time points to assess and compare the corrected QT interval (QTc) between the two groups. Data were analyzed using SPSS version 29, and a p-value < 0.05 was deemed significant.
resultsCisatracurium demonstrated significant reductions in QTc from pre-anesthesia to post-anesthesia and through recovery, with values of -9.325 ms (P = 0.045), -9.925 ms (P = 0.038), and - 19.359 ms (P = 0.016), respectively. Atracurium also showed reductions but a notable increase in QTc after anesthesia to the end of surgery (32.322 ms, P = 0.0019). Throughout the procedure, Cisatracurium maintained shorter QTc intervals compared to Atracurium (e.g., T0: 420.07 ms vs. 434.75 ms, P = 0.03), but post-recovery, no significant differences were observed (Cisatracurium: 440.05 ms; Atracurium: 439.80 ms, P = 0.489).
conclusionsAtracurium causes more QT prolongation than Cisatracurium. While both affect QTc intervals, Cisatracurium has a more stable impact on cardiac repolarization, making it safer for patients at risk of QT prolongation. Cisatracurium's minimal impact on cardiovascular function, especially in patients with low ejection fraction, makes it the preferred choice for maintaining cardiac stability.
