However, there is still confusion surrounding how conventional components should be used to support traumatically injured bleeding patients, particularly concerning how platelets should be counted in a ratio\u2010based approach and when the resuscitation can switch from a ratio\u2010based to a laboratory\u2010guided approach.<\/jats:p><\/jats:sec><jats:sec><jats:title>CASE REPORT<\/jats:title><jats:p>A traumatically injured patient, who was resuscitated with 10 units of red blood cells (RBCs), 6 units of plasma, 2 units of apheresis platelets, and 5 pools of cryoprecipitate is described. After hemostasis was achieved, and in the setting of an international normalized ratio of 1.2, the clinical team requested 4 additional units of plasma because \u201cthe patient was not resuscitated with a 1:1 ratio of RBCs to plasma.\u201d This case illustrates that misconceptions surrounding resuscitation with conventional components may lead to unnecessary transfusions in patients with normal laboratory values who have achieved hemostasis.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>This report provides clarification as to how conventional components can be used for trauma resuscitation and why there is no need to transfuse additional plasma\u2010containing components to achieve a desired ratio when the patient is no longer bleeding and laboratory values are within normal limits. Furthermore, each dose of platelets is suspended in roughly the equivalent of 1 additional unit of plasma that should also be considered in the cumulative dose of plasma administered when using a ratio\u2010based
