[Consensus document on ultrasound training in Intensive Care Medicine. Care process, use of the technique and acquisition of professional skills]. / Documento de consenso para la formación en ecografía en Medicina Intensiva. Proceso asistencial, uso de la técnica y adquisición de competencias profesionales.

Ultrasound has become an essential tool in assisting critically ill patients. His knowledge, use and instruction requires a statement by scientific societies involved in its development and implementation. Our aim are to determine the use of the technique in intensive care medicine, clinical situations where its application is recommended, levels of knowledge, associated responsibility and learning process also implement the ultrasound technique as a common tool in all intensive care units, similar to the rest of european countries. The SEMICYUC's Working Group Cardiac Intensive Care and CPR establishes after literature review and scientific evidence, a consensus document which sets out the requirements for accreditation in ultrasound applied to the critically ill patient and how to acquire the necessary skills. Training and learning requires a structured process within the specialty. The SEMICYUC must agree to disclose this document, build relationships with other scientific societies and give legal cover through accreditation of the training units, training courses and different levels of training.

Improving echographic monitoring of hemodynamics in critically ill patients: Validation of right cardiac output measurements through the modified subcostal window.

OBJECTIVE: We aimed to assess the usefulness of using the right ventricle outflow tract (RVOT) velocity-time integral (VTI) for echocardiographic monitoring of cardiac output compared to the gold standard, the VTI along the left ventricle outflow tract (LVOT). DESIGN: Prospective observational study. SETTING: A tertiary intensive care unit. PATIENTS: 100 consecutive patients. INTERVENTIONS: echocardiographic monitoring in critically ill patients. MAIN VARIABLES OF INTEREST: We used intraclass correlation coefficients (ICC) to compare echocardiographic measurements of LVOT VTI through apical window with RVOT VTI through the parasternal and modified subcostal windows and to assess interobserver reproducibility. Preplanned post hoc analyses compared the ICC between ventilated and nonventilated patients. RESULTS: At the time of echocardiography, 44 (44%) patients were mechanically ventilated and 28 (28%) were receiving vasoactive drugs. Good-quality measurements were obtained through the parasternal short-axis and/or apical views in 81 (81%) patients and in 100 (100%) patients through the subcostal window. Consistency with LVOT VTI was moderate for RVOT VTI measured from the modified subcostal view (ICC 0.727; 95%CI: 0.62-0.808) and for RVOT VTI measured from the transthoracic view (0.715; 95%CI: 0.59-0.807). CONCLUSIONS: Measurements of RVOT VTI are moderately consistent with measurements of LVOT VTI. Adding the modified subcostal window allows monitoring RVOT VTI in all the patients of this selected cohort, even those under mechanical ventilation.

[Role of echocardiography in the hemodynamic monitorization of critical patients]. / Papel de la ecocardiografía en la monitorización hemodinámica de los pacientes críticos.

The use of echocardiography in intensive care units in shock patients allows us to measure various hemodynamic variables in an accurate and a non-invasive manner. By using echocardiography not only as a diagnostic technique but also as a tool for continuous hemodynamic monitorization, the intensivist can evaluate various aspects of shock states, such as cardiac output and fluid responsiveness, myocardial contractility, intracavitary pressures, heart-lung interaction and biventricular interdependence. However, to date there has been little guidance orienting echocardiographic hemodynamic parameters in the intensive care unit, and intensivists are usually not familiar with this tool. In this review, we describe some of the most important hemodynamic parameters that can be obtained at the patient bedside with transthoracic echocardiography in critically ill patients.

Objetivo Valorar la utilidad de la integral velocidad-tiempo (IVT) del tracto de salida del ventrículo derecho (TSVD) para la monitorización del gasto cardíaco comparado con el gold standard, el IVT del tracto de salida del ventrículo izquierdo (TSVI). Diseño Estudio prospectivo observacional. Ámbito UCI de un hospital terciario. Paciente Cien pacientes consecutivos. Intervenciones Ecocardiografías realizadas para monitorización hemodinámica. Variables de interés principales Usamos el coeficiente de correlación intraclase (CCI) para comparar las mediciones de IVT TSVI a través de la ventana apical con el IVT TSVD a través de la ventana paraesternal y subcostal modificada y la reproducibilidad interobservador. Se planeó un análisis post hoc para comparar los resultados en pacientes ventilados con no ventilados. Resultados En el momento de la ecografía, 44 (44%) pacientes estaban en ventilación mecánica y 28 (28%) recibían fármacos vasoactivos. Mediciones de buena calidad se obtuvieron a través de la ventana paraesternal o apical en 81 (81%) pacientes, y en 100 (100%) con la ventana subcostal modificada. La consistencia del IVT TSVI fue moderada con el IVT TSVD medido con la ventana subcostal modificada (CCI 0,727; IC 95%: 0,62-0,808) y la transtorácica (0,715; IC 95%: 0,59-0,807). Conclusiones El IVT TSVD presenta una consistencia moderada cuando se compara con el IVT TSVI. Añadir la ventana subcostal modificada permite monitorizar el IVT TSVD en todos los pacientes de esta cohorte, incluso aquellos con ventilación mecánica (AU)
