Optimizing Cardiac Surgery

OPTIMIZING BLOOD MANAGEMENT™:
A multi-strategy approach to controlling inflammatory response

Beyond the Economic Impact of transfusion

According to Timothy Hannon, M.D., President and Founder of the Strategic Healthcare Group, a blood management consulting firm, "In 2008, everyone was talking about [blood management].  In 2009, everyone wants to do it."

Indeed, as the cost of donor blood has risen in recent years and supplies have dwindled, hospitals have been encouraging clinicians to examine their use of donor blood products and adopt blood management programs.  Interest in blood management is widespread and not limited to clinical discussion; the topic has been reported on in such non-clinical publications as the Wall Street Journal.1 

Although the renewed attention to blood management is primarily cost-driven, clinicians have long recognized the clinical benefits associated with minimizing the use of donor blood. Transfusions have been linked to many negative outcomes, including the single biggest cause of morbidity and mortality after cardiac surgery - inflammatory response.2-4

A Multi-Strategy Approach

However, reducing transfusions is but one strategy that can be employed to reduce inflammatory response.  For decades, surgeons, anesthesiologists and perfusionists have studied the interrelated causes and multiple effects of inflammatory response in attempts to minimize the impact of cardiopulmonary bypass. In addition to reducing transfusions, cardiac teams have documented several additional important strategies:

  • Minimizing the blood/foreign surface interface 5
  • Reducing microemboli 6
  • Reducing inflammatory mediators 7,8

Each of these can be addressed, at least partly, through the conduct of cardiopulmonary bypass where the adoption of even a single new technology or technique can create an incremental improvement in the reduction of inflammatory response.
