Pérdidas sanguíneas diagnósticas en pacientes con trauma grave / Diagnostic blood losses in severe trauma patients

ObjetivoExaminar el perfil de pérdidas sanguíneas diagnósticas (extracciones analíticas) e iatrogénicas (técnicas de depuración extracorpórea [TDE]) en pacientes con trauma grave.MétodoEstudio descriptivo observacional prospectivo durante un año. Incluimos aquellos pacientes mayores de 15 años ingresados por trauma grave con Injury Severity Score (ISS) superior o igual a 16 puntos. Excluimos a aquellos pacientes a los que se hubiera indicado limitación del esfuerzo terapéutico. De 225 pacientes, con 1.619 días de evolución, analizamos volumen perdido/día/paciente, tipo de extracción, evolución clínica y presencia o no de TDE. Las variables se expresan como media±SD comparadas con la prueba de la t de Student.ResultadosEl promedio de pérdidas hemáticas/paciente/día ha sido de 55,5±32,2cm3. Encontramos diferencias estadísticamente significativas en el volumen sanguíneo extraído, comparando el primer día respecto al segundo (73,5±32,2 vs. 56,3±21,9cm3; p<0,001); evolución clínica (alta o éxitus) (54,8±33 vs. 60,7±24,9; p<0,05); gravedad (Injury Severity Score<31 o ≥31) (54,65±20 vs. 61,5±28,5; p<0,001) y sin TDE/TDE (50,9±18,9 vs. 97,2±72,6; p<0,001).ConclusionesLa mayor pérdida de sangre diagnóstica se produce en la fase de resucitación, en los pacientes que fallecen, en aquellos con mayor gravedad y los sometidos a TDE (AU)

ObjectiveTo analyze diagnostic (blood drawings) and iatrogenic (Continuous Renal Replacement Therapy, CRRT) blood losses (BL) in severe trauma patients.MethodA one-year descriptive, prospective and observational study. We included patients over 15 years of age, admitted with severe trauma and who had a score of ≥16 on the Injury Severity Index (ISS). Those patients in whom limitation of therapeutic effort had been indicated were excluded. A total of 225 patients with 1619 days of evolution were analyzed for volume of BL/day/patient, type of diagnostic test, clinical outcome and utilization of CRRT. The variables were described as mean ± standard deviation with the Student's T test.ResultsAverage blood loss of patient per day was 55.5±32.2cc. Statistically significant differences were found between the blood volume drawn when the first day was compared to the second day, 73.5±32.2 vs. 56.3±21.9 (p<0.001); clinical outcome (alive vs death) 54.8±33 vs. 60.7±24.9 (p<0.05); severity (ISS<31 or ≥31) 54.65±20 vs. 61.5±28.5 (p<0.001), No RRT vs RRT: 50.9±18.9 vs. 97.2±72.6 (p<0.001).ConclusionsThe greatest diagnostic BL occurs during the resuscitation phase, in the patients who die, in those with greater severity and those undergoing CRRT (AU)

OBJECTIVE: To analyze diagnostic (blood drawings) and iatrogenic (Continuous Renal Replacement Therapy, CRRT) blood losses (BL) in severe trauma patients. METHOD: A one-year descriptive, prospective and observational study. We included patients over 15 years of age, admitted with severe trauma and who had a score of > or =16 on the Injury Severity Index (ISS). Those patients in whom limitation of therapeutic effort had been indicated were excluded. A total of 225 patients with 1619 days of evolution were analyzed for volume of BL/day/patient, type of diagnostic test, clinical outcome and utilization of CRRT. The variables were described as mean +/- standard deviation with the Student's T test. RESULTS: Average blood loss of patient per day was 55.5+/-32.2 cc. Statistically significant differences were found between the blood volume drawn when the first day was compared to the second day, 73.5+/-32.2 vs. 56.3+/-21.9 (p<0.001); clinical outcome (alive vs death) 54.8+/-33 vs. 60.7+/-24.9 (p<0.05); severity (ISS<31 or > or =31) 54.65+/-20 vs. 61.5+/-28.5 (p<0.001), No RRT vs RRT: 50.9+/-18.9 vs. 97.2+/-72.6 (p<0.001). CONCLUSIONS: The greatest diagnostic BL occurs during the resuscitation phase, in the patients who die, in those with greater severity and those undergoing CRRT.
