Estrategias de protección renal en Anestesiología y Cuidados Críticos

In the perioperative setting, acute kidney injury (AKI) is a common complication. By itself, the presence of AKI is associated with adverse outcomes, such as increased risk of chronic kidney disease and mortality. Several risk factors are associated with the appearance of perioperative AKI and identifying them is crucial to initiate renal protective measures. Some renoprotective strategies have been shown to be helpful, others are still under investigation, and others are no longer recommended because they are ineffective or even harmful. The lack of efficacy of these therapies could be due to the fact that the therapy was started too late. The new renal biomarkers allow the identification of kidney damage without loss of function, thus allowing the implementation of preventive measures. The purpose of this review is to present an updated summary of the current evidence about the risk factors and mechanisms that lead to the appearance of AKI in the perioperative and the intensive care unit, as well as the different renoprotective strategies and treatments.En el contexto perioperatorio, el daño renal agudo (acute renal injury o AKI) es una complicación frecuente. Por sí mismo, la presencia de AKI se asocia con resultados adversos, tales como mayor riesgo de enfermedad renal crónica (ERC) y de mortalidad. Varios factores de riesgo están asociados con la aparición de AKI perioperatorio e identificarlos es crucial para iniciar medidas de protección renal.  Algunas estrategias renoprotectoras han demostrado ser útiles, otras se encuentran aún en investigación y otras ya no se recomiendan porque son ineficaces o incluso dañinas. La falta de eficacia de estas terapias podría deberse al hecho de que la terapia se inició demasiado tarde. Los nuevos biomarcadores renales permiten identificar el daño renal sin pérdida de función permitiendo así la implementación de medidas preventivas.  El propósito de esta revisión es mostrar un resumen actualizado de la evidencia actual acerca de los factores de riesgo y los mecanismos que nos conducen a la aparición de AKI perioperatorio y en unidad de cuidados críticos así como las diferentes estrategias y tratamientos renoprotectores

Evolution over Time of Ventilatory Management and Outcome of Patients with Neurologic Disease∗

OBJECTIVES: To describe the changes in ventilator management over time in patients with neurologic disease at ICU admission and to estimate factors associated with 28-day hospital mortality. DESIGN: Secondary analysis of three prospective, observational, multicenter studies. SETTING: Cohort studies conducted in 2004, 2010, and 2016. PATIENTS: Adult patients who received mechanical ventilation for more than 12 hours. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Among the 20,929 patients enrolled, we included 4,152 (20%) mechanically ventilated patients due to different neurologic diseases. Hemorrhagic stroke and brain trauma were the most common pathologies associated with the need for mechanical ventilation. Although volume-cycled ventilation remained the preferred ventilation mode, there was a significant (p < 0.001) increment in the use of pressure support ventilation. The proportion of patients receiving a protective lung ventilation strategy was increased over time: 47% in 2004, 63% in 2010, and 65% in 2016 (p < 0.001), as well as the duration of protective ventilation strategies: 406 days per 1,000 mechanical ventilation days in 2004, 523 days per 1,000 mechanical ventilation days in 2010, and 585 days per 1,000 mechanical ventilation days in 2016 (p < 0.001). There were no differences in the length of stay in the ICU, mortality in the ICU, and mortality in hospital from 2004 to 2016. Independent risk factors for 28-day mortality were age greater than 75 years, Simplified Acute Physiology Score II greater than 50, the occurrence of organ dysfunction within first 48 hours after brain injury, and specific neurologic diseases such as hemorrhagic stroke, ischemic stroke, and brain trauma. CONCLUSIONS: More lung-protective ventilatory strategies have been implemented over years in neurologic patients with no effect on pulmonary complications or on survival. We found several prognostic factors on mortality such as advanced age, the severity of the disease, organ dysfunctions, and the etiology of neurologic disease
