Effect of Atracurium versus Cisatracurium on QT interval changes in patients undergoing cataract surgery: a randomized clinical trial.

Background: Muscle 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.

Method: This double-blind, parallel-group randomized clinical trial (RCT) was conducted in 2023 in Hamadan, Iran.
