Insights
Minimalized extracorporeal cardiopulmonary (MECC) systems significantly reduce allogeneic blood product transfusions in coronary artery bypass grafting. MECC also leads to shorter intensive care unit and hospital stays compared to standard systems.
Area of Science:
- Cardiovascular Surgery
- Cardiopulmonary Bypass Technology
- Transfusion Medicine
Background:
- Intraoperative allogeneic blood product transfusion (ABPT) in cardiac surgery is linked to adverse patient outcomes.
- Minimally invasive techniques are sought to improve surgical results and reduce complications.
Purpose of the Study:
- To compare the incidence of ABPT in patients undergoing on-pump coronary artery bypass grafting using a minimalized extracorporeal cardiopulmonary (MECC) system versus a standard extracorporeal circulation (sECC) system.
- To evaluate the impact of MECC on postoperative complications and resource utilization.
Main Methods:
- A retrospective review of 156 patients undergoing myocardial revascularization between 2008 and 2010.
- 83 patients were treated with MECC, and 73 with sECC.
- Analysis of intraoperative and early postoperative ABPT, complications, and length of stay.
Main Results:
- No significant difference in operative mortality or morbidity between MECC and sECC groups.
- Significantly lower intraoperative (7.2% vs. 60.3%) and early postoperative (19.3% vs. 57.5%) ABPT rates in the MECC group (p<0.001).
- Shorter skin-to-skin, cardiopulmonary bypass, and X-clamp times, as well as reduced ICU and hospital stay, were observed with MECC (p<0.05 for all).
Conclusions:
- MECC application in on-pump coronary artery bypass grafting significantly reduces ABPT and shortens ICU and hospital stays.
- Key strategies for maximizing MECC benefits include autologous retrograde priming, BIS monitoring, cell salvage, meticulous hemostasis, and strict volume management.
Aim:
Intraoperative allogeneic blood product transfusion (ABPT) in cardiac surgery is associated with worse overall outcome, including mortality. The objective of this study was to evaluate the ABPTs in minimalized extracorporeal cardiopulmonary (MECC(TM)) compared with standard open system on-pump coronary revascularization.
Methods:
Data of 156 patients undergoing myocardial revascularization between September 2008 and September 2010 were reviewed. 83 patients were operated by the MECC technique and 73 were treated by standard extracorporeal circulation (sECC). ABPT and overall early postoperative complications were analyzed.
Results:
Operative mortality and morbidity were similar in both groups. ABPT in the MECC group was significantly lower than in the sECC group both intraoperatively (7.2 vs. 60.3% of patients p<0.001) and during the first five postoperative days (19.3 vs. 57.5%; p<0.001). "Skin to skin"- (214 ± 45 vs. 232 ± 45 min; p=0.012), cardiopulmonary bypass (CPB) - (82 ± 25 vs. 95 ± 26 min; p=0.014), and X-clamp- times (50 ± 16 vs. 56 ± 17 min; p=0.024) were significantly lower in the MECC group than in the sECC group. Length of ICU (intensive care unit) - and hospital stay were also significantly lower in the MECC group vs. the sECC group (26.7 ± 20.2 vs. 54.5 ± 68.9 h; p<0.001, and 12.0 ± 4.1 vs. 14.5 ± 4.6 days; p<0.001).
Conclusion:
Application of MECC as on-pump coronary artery bypass graft (CABG) results in significantly lower ABPT as well as shorter ICU and in-hospital stay. In order to achieve these benefits of MECC autologous retrograde priming, Bispectral index (BIS) monitoring, intraoperative cell salvage, meticulous hemostasis and strict peri- and postoperative volume management are crucial.
