Point-of-care haemostasis monitoring during liver transplantation reduces transfusion requirements and improves patient outcome. Clin Chim Acta. 2015 Jun 15;446:277-83.https://hdl.handle.net/10668/23208Background Optimal haemostasis management can improve patient outcomes and reduce blood loss and transfusion volume in orthotopic-liver-transplant (OLT). Methods We performed a prospective study including 200 consecutive OLTs. The first 100 patients were treated according to the clinic's standards and the next 100 patients were treated using the new point-of-care (POC)-based haemostasis management strategy. Transfusion parameters and other outcomes were compared between groups. Results Transfusion requirements were reduced in the POC group. The median and IQR of red-blood-cells (RBC) transfusion units were reduced from 5 [2–8] to 3 [0–5] (p < 0.001), plasma from 2 [0–4] to 0 (p < 0.001), and platelets from 1 [0–4] to 0 [0–1] (p < 0.001), into the POC group only four patients received tranexamic acid and fibrinogen transfusion rate was 1.13 ± 1.44 g (p = 0.001). We also improved the incidence of transfusion avoidance, 5% vs. 24% (p < 0.001) and reduced the incidence of massive transfusion (defined as the transfusion of more than 10 RBC units), 13% vs. 2% (p = 0.005). We also observed a relationship between RBC transfusion requirements and preoperative haemoglobin, and between platelet transfusion and preoperative fibrinogen levels. The incidence of postoperative complications, such as, reoperation for bleeding, acute-kidney-failure or haemodynamic instability was significantly lower (13.0% vs. 5%, p = 0.048, 17% vs. 2%, p < 0.001, and 29% vs. 16%, p = 0.028). Overall, blood product transfusion was associated with increased risk of postoperative complications. Conclusions A haemostatic therapy algorithm based on POC monitoring reduced transfusion and improved outcome in OLT.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Blood-lossLiver-transplantationMeasurement techniques—coagulationMobile laboratoryPoint of care testingPoint-of-care haemostasis monitoring during liver transplantation reduces transfusion requirements and improves patient outcomeresearch article25916692restricted accessHemorragia posoperatoriaPérdida de sangre quirúrgicaTrasplante de hígadoCoagulación sanguíneaPruebas de coagulación sanguíneaFactores de coagulación sanguíneaPruebas en el punto de atención10.1016/j.cca.2015.04.022
