Paravertebral Block to Reduce the Incidence of New Onset Atrial Fibrillation After Cardiac Surgery: A Prospective Randomized Controlled Pilot Trial


This research is being done to determine if a procedure done by the anesthesiologist, known as a paravertebral block, can decrease the chance of developing atrial fibrillation after surgery. The block consists of using a numbing medication delivered over time through two small tubes to specific spots on the upper back. There is evidence that this helps reduce the chance of atrial fibrillation after similar procedures and the potential complications of that condition.
