Upon arrival in the ICU, baseline laboratory measures should be obtained and then repeated as needed or at least hourly: INR, aPTT, fibrinogen level, hemoglobin or hematocrit, platelet count, viscoelastic point-of-care testing (if available), ionized calcium, blood gas testing (including base deficit).
Once laboratory data are available, resuscitation should be goal directed based on the laboratory findings and clinical evidence of ongoing bleeding.
