Management of severe bleeding in a ruptured extrauterine pregnancy: a theragnostic approach.

Haemoperitoneum due to ruptured extrauterine pregnancy is a complication that may occur in the first trimester of pregnancy, but massive haemorrhage with severe shock is rare. When severe bleeding does occur, timely diagnosis and rapid haemostatic treatment are vital. We present the case of a 37-year-old woman with severe bleeding and shock due to ruptured extrauterine pregnancy.Management of the patient consisted of emergency laparotomy, red blood cell transfusion and targeted haemostatic therapy guided by rotational thromboelastometry using the fibrin-based clotting (FIBTEM) assay, (activation with tissue factor with addition of the platelet inhibitor cytochalasin D). As severe hypofibrinogenaemia was apparent, indicated by a FIBTEM maximum clot firmness (MCF) that was not measurable (i.e. < 2 mm) and a plasma fibrinogen level of 0.17 g/l, the patient was treated with 4 g fibrinogen concentrate. Tranexamic acid (1 g) was also administered.Rapid restoration of haemostasis was indicated by the improvement of thromboelastometric parameters (FIBTEM MCF 16 mm) and, later, laboratory coagulation tests (plasma fibrinogen 2.75 g/l), along with cessation of bleeding. No fresh frozen plasma (FFP) was administered. Surgery was successfully completed, and the patient was subsequently discharged 5 days after admission with no further complications. Haemorrhage in extrauterine pregnancy is commonly managed using autologous blood transfusion (via cell salvage) and homologous plasma transfusion. In this case of severe bleeding and shock due to ruptured extrauterine pregnancy, thromboelastometry-guided administration of fibrinogen concentrate enabled rapid restoration of haemostasis, complete avoidance of FFP transfusion and resulted in a successful outcome.

Rotational thromboelastometry analysis and management of life-threatening haemorrhage in isolated craniofacial injury.

Massive haemorrhage from facial fractures is rare but the associated mortality rate is high. Here, we describe a case in which thromboelastometry [rotational thromboelastometry (ROTEM)]-guided administration of prothrombin complex concentrate and fibrinogen concentrate was effective in correcting coagulopathy in a 68-year-old man with serious craniofacial trauma and massive haemorrhage. The patient, a cyclist who collided with a car, was transferred to the emergency department of our hospital with signs of shock and significant bleeding from multiple fractures and soft tissue injuries to the face. Blood gas analysis and standard laboratory tests revealed the presence of anaemia and acidosis, and our massive haemorrhage protocol was initiated. E-FAST and total-body computed tomography scans excluded the possibility of bleeding from other sites. All efforts were directed towards stopping bleeding from craniofacial lesions, but the surgeon experienced difficulty in maintaining haemostasis. ROTEM analysis revealed severe coagulopathy and was indispensable in guiding transfusion: 2 g tranexamic acid, followed by 1000 IU prothrombin complex concentrate, 5 g fibrinogen and 2 U platelet concentrate. Two hours later, ROTEM analysis showed that coagulopathy had been corrected, and haemostasis was confirmed by cessation of bleeding. This report highlights the potential for using ROTEM to guide treatment with fibrinogen and prothrombin complex concentrates in the presence of profuse multifocal bleeding and severe coagulopathy.
