One recent trend that has interested me while working as a critical care nurse has been the incidence of post operative atrial fibrillation following cardiothoracic surgery. Statistically, our patients have a 25% likelihood of having a post operative atrial fibrillation (POAF) event. This is typically contributed to pericardial inflammation due to oxidative stress and ectopic misfiring as well as often some sort of electrolyte imbalance exists as well. Studies have shown that preoperative administration of a low dose b-blocker to cardiac patients has shown a 48% reduction in risk of POAF. This an ultimately improve patient outcomes as post operative atrial fibrillation is often associated with stroke, thrombophlebitis, MIs and extended hospital stays. This is an area that I believe needs to be researched more extensively so that better treatment guidelines can be made regarding the use of beta blockers in reducing cardiac arrythmia events in patients that are known to be high risk.
