BackgroundSurgical excision of burn wounds is often associated with severe bleeding. Timely and targeted correction of coagulopathy reduces transfusion requirements and improves survival in trauma victims. We hypothesized that rapid correction of coagulopathy after a treatment algorithm based on point-of-care viscoelastic coagulation testing would decrease allogeneic blood product transfusions during surgical excision of burn wounds.MethodsThirty consecutive patients undergoing surgical excision of burn wounds were enrolled into this prospective, randomized, controlled, single-centre study. In the control group, coagulation management was performed according to the clinicians' discretion. For the algorithm group, we standardized treatment based on the Austrian recommendation for the management of trauma-induced coagulopathy using point-of-care rotational thromboelastometry (ROTEM(®)). The main outcome parameter was the cumulative number of allogeneic blood units transfused on the day of surgery.ResultsThe difference between the groups regarding the cumulative use of allogeneic blood products was highly significant with 3.0 (1.3-5.5) blood products in the algorithm group compared with 9.0 (6.0-12.3) in the control group [median (inter-quartile range); P=0.002]. No plasma was administered in the algorithm group compared with 5.0 (1.5-7.5) units overall in the control group (P<0.001). Fibrinogen concentrate administration was not significantly different between the groups (P=0.89). Tranexamic acid was not administered.ConclusionsThe significant reduction in allogeneic blood product requirements during surgical burn wound excision is a prospective proof of concept that a bleeding management algorithm based on thromboelastometry is efficacious. Hypofibrinogenaemia and hyperfibrinolysis are not significant pathomechanisms of bleeding in this setting and ROTEM(®) helps to avoid unnecessary interventions.
