Leave No Clot Behind Part 2: Preventing Retained Blood Reduces Post Op Atrial Fib (POAF)

AFib-shutterstock_89144557Chest tubes are used to prevent retained clot around the heart in patients recovering from heart surgery. Chest tubes often fail by clogging, leading to retained blood syndrome.1, 2 Growing evidence suggests that retained blood is one of the most potent triggers for developing Post Operative Atrial Fibrillation (POAF).3 POAF is the most common complication after Cardiac Surgery, leading to longer and more expensive hospital stays, readmissions and death during early recovery.4, 5  Prevention strategies have long been sought to reduce associated complications, mortality and costs, although none have become universal. Common strategies to prevent POAF have relied on prophylactic drugs, mostly consisting of attempts to block arrhythmias (digoxin, metoprolol, carvedilol, amiodorone) or blunt the inflammatory responses (fish oil, steroids, N-Acetyl Cystine, Colchicine). Various trials have shown modest reductions in POAF with these approaches, but drugs in these categories can have serious side effects.6 Thus current guidelines caution these approaches should be used selectively rather than on all patients to minimize side effects.

One approach that has consistently reduced POAF in randomized trials even better than prophylactic drugs is to limit the amount of blood retained around the heart in the pericardium after cardiac surgery.3, 7 Various pericardiotomy approaches have been tried, all of which rely on shunting blood from the pericardium to pleural spaces.8 There are downsides and risks, including the risk of heart and bypass graft herniation, adhesions and the contribution to the development of pleural effusions that limit recovery since the blood is simply moved from one cavity (pericardial) to another (pleural).3

Active Clearance Technology utilizing PleuraFlow to keep chest tubes clear of clot during the first 24 hours after surgery may offer a best of all worlds, simple, easy to adopt approach to not only reduce the incidence of POAF, but also reduce the need for reinterventions for pericardial and pleural effusions without the risk of adhesions and herniation.9-12 In a peer reviewed study presented at CVT Critical Care Conference and published in the Journal of Thoracic and Cardiovascular Surgery, PleuraFlow reduces retained blood by 43% and POAF by 33% in propensity matched patients.13  This approach shows considerable promise not only to reduce complications and costs from POAF by making a simple change in drainage management technique in the ICU, but also reduce overall healthcare costs.

What’s your ICU protocol to keep chest tubes free of clogging and prevent retained blood during early recovery after heart surgery?
