EDUCATIONAL WEBINAR: Evidence-Based Strategy in the Prevention of Complications due to Retained Blood

An Educational Webinar with Presenters: Marc Gillinov, MD, Marc Gerdisch, MD, and Alyson Mehringer, RN discussing the basic principles of Chest Tube Management, the results of a 1 year quality improvement study and the operational perspective from the ICU Nursing Staff.

Proactive Protocols to Reduce Complications After Cardiac Surgery

Improving outcomes and reducing costs is a continual effort in modern healthcare. For heart surgery patients, a good place to start is by focusing on something that is common to nearly all patients recovering. All cardiac surgery patients have some degree of bleeding postoperatively, and chest tubes are used to evacuate this blood from the pleural and/or pericardial spaces. Studies have shown that higher chest tube output is statistically associated with longer ICU stays, more complications, higher costs, and a greater risk of mortality. (1, 2)

The tipping point in terms of patient outcomes occurs early in the recovery period, within the first six hours postoperatively, and when total chest tube output exceeds 200mL in any one-hour period. (1) A part of the problem may not be what is evacuated, but what is not evacuated. (2) Chest tube clogging, which has been found to occur in 36% of heart surgery patients, can cause blood to be retained around the heart and lungs, which can lead to Retained Blood Complex  (RBC). (3) Chest tube clogging is also statistically associated with more complications, including atrial fibrillation. (3)


The link between outcomes and postoperative bleeding has led many hospitals to look at their postoperative evacuation management protocols. Nurses in the postoperative ICU, among many other things, monitor chest tube output, check for indications that the tubes are obstructed, and notify the physicians if chest tube output suddenly ceases or reaches an alarming level. In the absence of defined tube management protocols to address chest tube clogging, however, clinicians use makeshift methods  like milking, tapping, stripping, and open suction. These approaches are all reactive, and none have been shown to have clinical benefit. (4-6) By the time clot is visualized in the chest tubes, the evacuation has often been impaired for some time, allowing blood and clot  to accumulate in the pleural and/or pericardial spaces. 

Proactive clearance with PleuraFlow ACT, however, has been shown to be clinically efficient, to improve the evacuation of post-surgical blood, and to reduce the volume of blood retained in the surgical spaces. (7-9) With PleuraFlow ACT, the only FDA cleared chest tube clearance system, hospitals are now developing chest tube clearance protocols to proactively prevent chest tube clogging. By actively and systematically maintaining chest tube patency, top hospitals are working to improve the efficiency of chest tube management, and potentially decrease incidence of RBC complications by reducing the volume of retained post-surgical blood.
