A total of 41 patients underwent aortic arch surgery were analyzed:15 (37%) and 26 (63 %) in RPT and FET group, respectively. The use of RPT showed a significant shorter circulatory arrest times than FET: 9 min vs 58 min (P < 0.001), respectively. The median lactates peak in the first 24h post intervention was 2.6 for RPT group and 5.4 mmol/L for FET group, (P <0.0001). When compared with the FET, RPT is associated with significant reduction in the use of packed red blood cells (P <0.0001), fresh frozen plasma (P <0.0001), platelet concentrate (P <0.0001), and fibrinogen (P <0.004). The median ICU stay was 3 and 9 days (P = 0.011), whereas the median hospital stay was 12 and 18.5 days (P=0.004) in the RPT and FET groups, respectively. Thirty-day mortality and postoperative outcomes were comparable between the two groups.
