A prospective study on the correlation between thromboelastometry and standard laboratory tests - influence of type of surgery and perioperative sampling times.

This prospective study aimed at investigating the influence of surgery type and perioperative sampling times on the correlations between rotational thromboelastometry (ROTEM) parameters and standard laboratory coagulation tests assessing comparable coagulation phases. Patients undergoing glioblastoma multiforme resection (GBR group,  = 60) or laparoscopic colon cancer resection (CCR group,  = 40) were prospectively included. Blood samples for ROTEM and laboratory assessments were consecutively drawn within 24-hours prior to surgery (baseline), and at 2, 24 and 48-hours after surgery.

Administration of fibrinogen concentrate for refractory bleeding in massively transfused, non-trauma patients with coagulopathy: a retrospective study with comparator group.

Background: This retrospective, single centre study was conducted to investigate the efficacy of fibrinogen concentrate (FBNc) in decreasing blood requirements and reaching optimal fibrinogen level, in non-trauma, massively transfused, bleeding patients with coagulopathy.

Methods: Over a 3-years period, all patients for whom a massive transfusion protocol was activated and had received ≥ 4 units of allogeneic blood components within a ≤ 4 h period, were included. Patients were classified according to whether they received FBNc or achieved an optimal fibrinogen level of ≥ 2 g/L within 24 h after FBNc administration.
