Original article title
Efficacy of Stellate Ganglion Block for Preventing Postoperative Atrial Fibrillation After Cardiac Surgery: A Randomized, Double-Blind, Placebo-Controlled Trial.
Takeaway
A placebo-controlled valve-surgery trial found that a stellate ganglion block did not reduce postoperative atrial fibrillation. Signals of fewer intraoperative ventricular arrhythmias and kidney injuries were secondary findings and need confirmation.
Keep in mind
Single-center randomized trial; primary endpoint negative.
