Pathophysiology and Treatment of Coagulopathy in Massive Hemorrhage and Hemodilution

et al. 2010

Fluid resuscitation after massive hemorrhage in major surgery and trauma may result in extensive hemodilution and coagulopathy, which is of a multifactorial nature. Although coagulopathy is often perceived as hemorrhagic, extensive hemodilution affects procoagulants as well as anticoagulant, profibrinolytic, and antifibrinolytic elements, leading to a complex coagulation disorder. Reduced thrombin activation is partially compensated by lower inhibitory activities of antithrombin and other protease inhibitors, whereas plasma fibrinogen is rapidly decreased proportional to the extent of hemodilution. Adequate fibrinogen levels are essential in managing dilutional coagulopathy. After extensive hemodilution, fibrin clots are more prone to fibrinolysis because major antifibrinolytic proteins are decreased.Fresh frozen plasma, platelet concentrate, and cryoprecipitate are considered the mainstay hemostatic therapies. Purified factor concentrates of plasma origin and from recombinant synthesis are increasingly used for a rapid restoration of targeted factors. Future clinical studies are necessary to establish the specific indication, dosing, and safety of novel hemostatic interventions.

“…Deviation from the 1:1:1 target ratio was also observed in Shaz et al's study involving 132 civilian trauma patients; in that study, the MTP achieved a mean FFP:pRBC ratio of 0.5 and a mean PLT:pRBC ratio of 0.6. (22,23) Evidently, while an ideal transfusion ratio of 1:1:1 may be proposed in MTPs, it has been suggested that this target is not always achievable immediately. Notably, studies have shown that failure to achieve these ratios is associated with higher mortality.…”

INTRODUCTIONMassive transfusion protocol (MTP) is increasingly used in civilian trauma cases to achieve better haemostatic resuscitation in patients requiring massive blood transfusions (MTs), with improved survival outcomes. However, in non-trauma patients, evidence for MTP is lacking. This study aims to assess the outcomes of a newly established MTP in a civilian setting, for both trauma and non-trauma patients, in an acute surgical care unit.METHODS A retrospective cohort analysis was performed on 46 patients for whom MTP was activated in Changi General Hospital, Singapore. The patients were categorised into trauma and non-trauma groups. Assessment of Blood Consumption (ABC) score was used to identify MTP trauma patients and analyse over-activation rates. RESULTSOnly 39.1% of all cases with MTP activation eventually received MTs; 39.8% of the MTs were for non-trauma patients. Mean fresh frozen plasma to packed red blood cells (pRBC) ratio achieved with MTP was 0.741, while mean platelet to pRBC ratio was 0.213. The 24-hour mortality rate for all patients who received an MT upon MTP activation was 33.3% (trauma vs. non-trauma group: 45.5% vs. 14.3%). The ABC scoring system used for trauma patients had a sensitivity and specificity of 81.8% and 41.2%, respectively. CONCLUSION MTP may be used for both trauma and non-trauma patients in acute care surgery. Scoring systems to predict the need for an MT, improved compliance to predefined transfusion ratios and regular reviews of the MTP are necessary to optimise MTPs and to improve the outcomes of patients receiving MTs.

Increased number of coagulation products in relationship to red blood cell products transfused improves mortality in trauma patients

Abstract: In the civilian setting, plasma, PLT, and cryoprecipitate products significantly increased 30-day survival in trauma patients. Future prospective randomized clinical trials are required to determine the optimal transfusion ratios.
