Stellate Ganglion Blockade for the Prevention of Atrial Fibrillation After Cardiac Surgery: A Randomized Placebo-Controlled Trial
Mayo Clinic
Summary
The purpose of this study is to test if a nerve block procedure called a stellate ganglion block can help decrease the chance of atrial fibrillation after surgery. Atrial fibrillation is the abnormal, fast beating of the upper chambers of the heart. Stellate ganglion blockade has shown to decrease other types of abnormal heart rhythms as well as decrease the chance of atrial fibrillation.
Description
The investigator hypothesizes that stellate ganglion blockade with local anesthetic performed prior to cardiac surgery will reduce the incidence and duration of postoperative atrial fibrillation (POAF). Specific Aim 1: Determine the incidence of POAF in patients receiving pre-surgical stellate ganglion blockade with local anesthetic versus saline placebo within one week of surgery or during hospitalization if discharged prior to one week. Specific Aim 2: Determine the duration of POAF in patients receiving pre-surgical stellate ganglion blockade with local anesthetic versus saline placebo wi…
