    BackgroundBecause of the difficulties in evaluating injured children, screening blood tests are recommended.MethodsResuscitation blood tests (complete blood count, chem12, coagulation panel, urinalysis) were reviewed for abnormality frequency, injury correlation, managements, and outcome.ResultsPanels were obtained on 240 children (age < 16 years) meeting trauma system criteria. Abnormalities were identified as follows: white blood cell/hematocrit/platelets (41%, 27%, 1%), Na/K/Cl/CO(2) (3%, 30%, 23%, 14%), blood ureal nitrogen/creatinine (6%, 0%), prothrombin time/international normalized ratio/partial thromboplastin time (22%, 16%, 6%), aspartate aminotransferase/alanine transferase (43%, 35%), amylase (2%), glucose (77%), and urinalysis (31%). Organ-specific chemistries predicted injury poorly. Transaminasemia correlated with liver injury when levels exceeded 400 U/L. Two children (1%) with hyperamylasemia had abdominal injuries. Coagulation abnormalities correlated with intracranial injury (43%) and Glasgow Coma Scale (GCS 3 to 8; 56%, GCS 9 to 14; 20%, GCS 15; 14%, P <0.05). Only 25 (10%) had interventions for test abnormalities (11 transfusions, 8 fresh frozen plasma, 3 tests repeated, 3 KCl).ConclusionsRoutine laboratory panels are little value in the management of injured children.
