The effect of intravenous N-acetylcysteine on prevention of atrial fibrillation after coronary artery bypass graft surgery: a double-blind, randomised, placebo-controlled trial.

Background: Atrial fibrillation (AF) is one of the most frequently occurring dysrhythmias after coronary artery bypass graft (CABG) surgery.

Aim: The aim of this study was to evaluate the effect of intravenous N-acetylcysteine (NAC) on the prevention of AF after CABG surgery.

Methods: In a double-blind, randomised controlled trial, a total of 150 patients who were scheduled for on-pump CABG surgery were randomly assigned into two groups.

Comparing Hemodynamic Responses to Diazepam, Propofol and Etomidate During Anesthesia Induction in Patients with Left Ventricular Dysfunction Undergoing Coronary Artery Bypass Graft Surgery: a Double-blind, Randomized Clinical Trial.

Background: Anesthesia induction is often accompanied by a period of hemodynamic instability, which could be deleterious in patients with coronary artery disease (CAD) and left ventricular dysfunction undergoing coronary artery bypass graft (CABG) surgery. The aim of this study was to compare the hemodynamic responses to propofol, etomidate, and diazepam following anesthesia induction, laryngoscopy and intubation in CABG surgery patients with low ejection fraction (EF).

Methods: A double-blind randomized, clinical study was performed on 150 patients with CAD and left ventricular dysfunction (EF≤35%) scheduled for elective CABG surgery with Cardiopulmonary bypass (CPB).
