Sahli Jan‐Dirk Studt Julia Braun Justyna Lunkiewicz Donat R. Spahn Alexander Kaserer Transfusion AbstractIntroductionData on the perioperative bleeding risk associated with elevated plasma levels of direct factor Xa inhibitors (FXa inhibitors) are limited. This study examines perioperative red blood cell (RBC) loss in patients undergoing urgent surgery with a residual FXa inhibitor level exceeding 100 mcg/L and without preoperative FXa inhibitor reversal.MethodsThis retrospective analysis includes data from 32 patients who underwent urgent noncardiac surgery between 2018 and 2022. This study aims to analyze perioperative RBC loss in patients undergoing urgent surgery with a residual FXa inhibitor level exceeding 100 mcg/L and without preoperative FXa inhibitor antidote‐based reversal or unspecific treatment with 4‐factor prothrombin complex concentrate (PCC). All patients were managed using a watch‐and‐wait strategy.ResultsThe last determination of FXa inhibitor plasma concentration prior to surgery showed a median of 245 mcg/L (IQR 144–345), with a median time interval of 3.8 h (IQR 2.4–7.2) before incision. Median RBC loss during surgery was 49 mL (IQR 0–253), 189 mL (IQR 104–217) until POD1 and 254 mL (IQR 58–265) until POD3. Only one patient required intraoperative treatment with 4‐factor‐PCC and none required reversal with andexanet alfa. Linear regression models found no significant influence of FXa inhibitor plasma levels on intraoperative RBC loss. Rivaroxaban was associated with higher RBC loss until postoperative Day 1 compared with apixaban. No thromboembolic events were observed.ConclusionDespite markedly elevated plasma concentrations of residual direct FXa inhibitors, perioperative RBC loss was limited in patients undergoing urgent noncardiac surgery. The intraoperative watch‐and‐wait strategy with selective intraoperative FXa inhibitor reversal or treatment only when required appears to be an appropriate approach. 10.1111/trf.18021 http://creativecommons.org/licenses/by-nc-nd/4.0/ |
