- W2125868049 abstract "Conclusion: In patients with ruptured abdominal aortic aneurysms (AAA) who require massive transfusion, a more equivalent ratio of transfusion of packed red blood cells (PRBC) to fresh frozen plasma (FFP) is independently associated with lower 30-day mortality. Summary: Adverse predictors for survival after ruptured AAA include advanced age, preoperative shock, poor intraoperative hemodynamics, oliguria, and postoperative complications. Improved outcomes are associated with surgeon volume and specialty training. Researchers in resuscitation research have recently focused on types and amounts of blood products administered with respect to mortality after massive hemorrhage from trauma. It appears, that mortality in trauma patients who require at least 10 units of blood products in <24 hours can be decreased with increased administration of FFP and decreased administration of PRBC. A PRBC/FFP ratio of <2:1 seems to be associated with the greatest decrease in death after trauma (Holcomb JB, et al, Ann Surg 2008;248:447-58). The authors hypothesize that this should logically extend to patients with ruptured AAA who require massive transfusion. They investigated whether lesser ratios of PRBC/FFP transfusion would result in lower 30-day mortality in patients with ruptured AAA receiving massive transfusion. This was a retrospective review of patients undergoing emergent open ruptured AAA repair. Patients were included if they received >10 units of blood products before the conclusion of the operation. Data were analyzed for patient demographics, admission vital signs, perioperative variables, the amount of blood products transfused, laboratory values, and the PRBC/FFP ratio. A multivariant analysis model was used to evaluate the effects of individual variables on 30-day mortality. Of 168 patients undergoing repair of a ruptured AAA during the perioperative period, 128 patients (85% men) received at least 10 units of blood products. Mean age was 73 ± 9 years. The 30-day mortality was 22.6%, including 11 intraoperative deaths. The 30-day mortality was lower (15% vs 39%; P < .03) in patients who received transfusions with a PRBC/FFP ratio ≤ 2:1 compared with those with a ratio >2:1. Odds ratio for death in the low FFP group vs the high FFP ratio group was 4.23 (95% CI, 1.2-14.5). Patients who received transfusions with high FFP ratios had a 22.4% incidence of colon ischemia vs 41.1% in those who received transfusions with low FFP ratios (P = .004). Comment: The very low overall 30-day mortality of 22.6% in a group of patients undergoing open repair of a ruptured AAA is exemplary. Although this low mortality rate likely suggests some referral bias and transfer of patients to a regional center, the results are nonetheless excellent. The clear benefit in this study, and in the trauma literature, of a higher ratio of transfusion of FFP/PRBC in patients with massive hemorrhage strongly argues for a standardized protocol of resuscitation of patients with ruptured AAA." @default.
