چکیده

BACKGROUND Thromboelastometric evaluation of coagulation might be useful for prediction and management of bleeding after paediatric cardiac surgery. We tested the hypothesis that the use of a thromboelastometry-guided algorithm for blood product management reduces blood loss and transfusion requirements. METHODS We studied 78 patients undergoing paediatric cardiac surgery with cardiopulmonary bypass (CPB) for the initial 12 h after operation. Stepwise multiple linear regression was used to develop an algorithm to guide blood product transfusions. Thereafter, we randomly assigned 100 patients to conventional or algorithm-guided blood product management, and assessed bleeding and red cell transfusion requirements. RESULTS CPB time, post-bypass rotational thromboelastometry (ROTEM(®)) EXTEM amplitude at 10 min (A10), and FIBTEM-A10 were independently associated with chest tube drainage volume during the initial 12 h after operation. Discriminative analysis determined cut-off values of 30 mm for EXTEM-A10 and 5 mm for FIBTEM-A10, and estimated optimal intraoperative fresh-frozen plasma and platelet concentrate transfusion volumes. Thromboelastometry-guided post-bypass blood product management significantly reduced postoperative bleeding (9 vs 16 ml kg(-1), P<0.001) and packed red cell transfusion requirement (11 vs 23 ml kg(-1), P=0.005) at 12 h after surgery, and duration of critical care stay (60 vs 71 h, P=0.014). CONCLUSIONS Rotational thromboelastometry-guided early haemostatic intervention by rapid intraoperative correction of EXTEM-A10 and FIBTEM-A10 reduced blood loss and red cell transfusion requirements after CPB, and reduced critical care duration in paediatric cardiac surgical patients.

Monitoring of coagulation and platelet function

Background: Paediatric cardiac surgery has developed dramatically during the last decades. Today, a wide range of patients is operated on-from premature neonates to grown up children with congenital heart disease. Excessive bleeding during and after cardiac surgery is still common, and it is one of the most serious complications. In this thesis, we consider different aspects of monitoring of co...

Detection of coagulopathy in paediatric heart surgery [DECISION study]: study protocol

BACKGROUND Each year in the UK, ≈3000 children undergo major cardiac surgery requiring cardiopulmonary bypass. Approximately 40 % of these experience excessive bleeding necessitating red cell transfusion or treatment with other blood components. A further 40 % receive blood components because of the perception by clinicians that the risk of bleeding is high. Excessive bleeding and treatment wit...

Comparison of structured use of routine laboratory tests or near-patient assessment with clinical judgement in the management of bleeding after cardiac surgery.

BACKGROUND Using algorithms based on point of care coagulation tests can decrease blood loss and blood component transfusion after cardiac surgery. We wished to test the hypothesis that a management algorithm based on near-patient tests would reduce blood loss and blood component use after routine coronary artery surgery with cardiopulmonary bypass when compared with an algorithm based on routi...

The use of viscoelastic haemostatic assays in goal-directing treatment with allogeneic blood products – A systematic review and meta-analysis

BACKGROUND Management of the critically bleeding patient can be encountered in many medical and surgical settings. Common for these patients is a high risk of dying from exsanguination secondary to developing coagulopathy. The purpose of this meta-analysis was to systematically review and assess randomised controlled trials (RCTs) performed on patients in acute need for blood transfusions due t...

Transfusion in trauma: thromboelastometry-guided coagulation factor concentrate-based therapy versus standard fresh frozen plasma-based therapy

INTRODUCTION Thromboelastometry (TEM)-guided haemostatic therapy with fibrinogen concentrate and prothrombin complex concentrate (PCC) in trauma patients may reduce the need for transfusion of red blood cells (RBC) or platelet concentrate, compared with fresh frozen plasma (FFP)-based haemostatic therapy. METHODS This retrospective analysis compared patients from the Salzburg Trauma Centre (S...
