The severity of preoperative anemia escalates risk of poor short-term outcomes after lumbar spine fusion | European Spine Journal

Evaluar cómo la gravedad de la anemia preoperatoria afecta los resultados a los 90 días de la cirugía de fusión espinal.
Los pacientes con anemia preoperatoria de moderada a grave tienen un mayor riesgo de hospitalización prolongada, transfusiones y alta no domiciliaria. La optimización mejorada de la anemia preoperatoria puede reducir significativamente la utilización de la atención médica, y los cirujanos deben considerar estos riesgos en la planificación preoperatoria.

• Este artículo es un estudio retrospectivo que evaluó cómo la gravedad de la anemia preoperatoria afecta los resultados a los 90 días de la cirugía de fusión espinal. Los autores clasificaron a los pacientes según las definiciones de gravedad de la anemia de la Organización Mundial de la Salud para las comparaciones. Los resultados principales fueron los requerimientos de transfusión, el alta no domiciliaria, las readmisiones, las complicaciones y la duración de la estancia hospitalaria. Los autores utilizaron modelos de regresión multivariante para controlar las variables de confusión.
• El estudio incluyó a 2582 pacientes: el 2.7% con anemia moderada-grave, el 11.0% con anemia leve y el 86.3% sin anemia. Los pacientes con anemia moderada-grave tuvieron la estancia hospitalaria más larga (5.03 días frente a 4.14 y 3.59 días, p < 0.001) y el mayor riesgo de transfusión (52.2% frente a 13.0% frente a 2.69%, p < 0.001), alta no domiciliaria (39.1% frente a 27.8% frente a 15.4%, p < 0.001), readmisión (7.25% frente a 5.99% frente a 3.36%, p = 0.023) y complicaciones (13.0% frente a 9.51% frente a 6.20%, p = 0.012). En la regresión logística multivariante, tanto los pacientes con anemia leve como moderada-grave tuvieron un mayor riesgo de transfusión (OR: 37.3, p < 0.001; OR: 5.25, p < 0.001, respectivamente) y alta no domiciliaria (OR: 2.00, p = 0.021; OR: 1.71, p = 0.001, respectivamente) en comparación con los pacientes sin anemia. La gravedad de la anemia no se asoció independientemente con complicaciones o readmisión a los 90 días. En la regresión lineal multivariante, la anemia leve (β: 0.37, p = 0.001) y moderada-grave (β: 1.07, p < 0.001) se asociaron independientemente con la duración de la estancia hospitalaria.
• Los autores concluyeron que los pacientes con anemia preoperatoria moderada-grave tienen un mayor riesgo de mayor duración de la estancia, transfusiones y alta no domiciliaria. La optimización mejorada de la anemia preoperatoria puede reducir significativamente la utilización de los servicios de salud, y los cirujanos deben considerar estos riesgos en la planificación preoperatoria.

Transfusión en trauma craneoencefálico / Transfusion traumatic brain injury

Julio 16, 2018. No. 3143

Lo Mejor de Octavio Paz. PDF Trasfusión en trauma craneoencefálico Transfusion practices in traumatic brain injury Curr Opin Anaesthesiol. 2018 Apr;31(2):219-226. doi: 10.1097/ACO.0000000000000566. East JM1, Viau-Lapointe J1, McCredie VA1,2. Author information Abstract PURPOSE OF REVIEW: The aim of this review is to summarize the recent studies looking at the effects of anemia and red blood cell transfusion in critically-ill patients with traumatic brain injury (TBI), describe the transfusion practice variations observed worldwide, and outline the ongoing trials evaluating restrictive versus liberal transfusion strategies for TBI. RECENT FINDINGS: Anemia is common among critically-ill patients with TBI, it is also thought to exacerbate secondary brain injury, and is associated with an increased risk of poor outcome. Conversely, allogenic red blood cell transfusion carries its own risks and complications, and has been associated with worse outcomes. Globally, there are large reported differences in the hemoglobin threshold used for transfusion after TBI. Observational studies have shown differential results for improvements in cerebral oxygenation and metabolism after red blood cell transfusion in TBI. SUMMARY: Currently, there is insufficient evidence to make strong recommendations regarding which hemoglobin threshold to use as a transfusion trigger in critically-ill patients with TBI. There is also uncertainty whether the restrictive transfusion strategy used in general critical care can be extrapolated to acutely brain injured patients. Ultimately, the consequences of anemia-induced cerebral injury need to be weighed up against the risks and complications associated with red blood cell transfusion.

Progressive hemorrhagic injury after severe traumatic brain injury: effect of hemoglobin transfusion thresholds. Vedantam A1, Yamal JM2, Rubin ML2, Robertson CS1, Gopinath SP1. Author information J Neurosurg. 2016 Nov;125(5):1229-1234. Epub 2016 Mar 4. Abstract OBJECT. There is limited literature available to guide transfusion practices for patients with severe traumatic brain injury (TBI). Recent studies have shown that maintaining a higher hemoglobin threshold after severe TBI offers no clinical benefit. The present study aimed to determine if a higher transfusion threshold was independently associated with an increased risk of progressive hemorrhagic injury (PHI), thereby contributing to higher rates of morbidity and mortality. METHODS The authors performed a secondary analysis of data obtained from a recently performed randomized clinical trial studying the effects of erythropoietin and blood transfusions on neurological recovery after severe TBI. Assigned hemoglobin thresholds (10 g/dl vs 7 g/dl) were maintained with packed red blood cell transfusions during the acute phase after injury. PHI was defined as the presence of new or enlarging intracranial hematomas on CT as long as 10 days after injury. A severe PHI was defined as an event that required an escalation of medical management or surgical intervention. Clinical and imaging parameters and transfusion thresholds were used in a multivariate Cox regression analysis to identify independent risk factors for PHI. RESULTS Among 200 patients enrolled in the trial, PHI was detected in 61 patients (30.5%). The majority of patients with PHI had a new, delayed contusion (n = 29) or an increase in contusion size (n = 15). The mean time interval between injury and identification of PHI was 17.2 ± 15.8 hours. The adjusted risk of severe PHI was 2.3 times higher for patients with a transfusion threshold of 10 g/dl (95% confidence interval 1.1-4.7; p = 0.02). Diffuse brain injury was associated with a lower risk of PHI events, whereas higher initial intracranial pressure increased the risk of PHI (p < 0.001). PHI was associated with a longer median length of stay in the intensive care unit (18.3 vs 14.4 days, respectively; p = 0.04) and poorer Glasgow Outcome Scale scores (42.9% vs 25.5%, respectively; p = 0.02) at 6 months. CONCLUSIONS A higher transfusion threshold of 10 g/dl after severe TBI increased the risk of severe PHI events. These results indicate the potential adverse effect of using a higher hemoglobin transfusion threshold after severe TBI.

Abstract IMPORTANCE: There is limited information about the effect of erythropoietin or a high hemoglobin transfusion threshold after a traumatic brain injury. OBJECTIVE: To compare the effects of erythropoietin and 2 hemoglobin transfusion thresholds (7 and 10 g/dL) on neurological recovery after traumatic brain injury. ...Intravenous erythropoietin (500 IU/kg per dose) or saline. Transfusion threshold maintained with packed red blood cells. ....CONCLUSIONS AND RELEVANCE: In patients with closed head injury, neither the administration of erythropoietin nor maintaining hemoglobin concentration of greater than 10 g/dL resulted in improved neurological outcome at 6 months. The transfusion threshold of 10 g/dL was associated with a higher incidence of adverse events. These findings do not support either approach in this setting.
