Manejo con control de temperatura en los cuidados posparada cardiaca: documento de expertos / Management of temperature control in post-cardiac arrest care: an expert report

Actualmente, el control estricto de temperatura mediante hipotermia inducida (entre 32 y 36 oC) se considera un tratamiento de primera línea en el manejo de pacientes con parada cardiaca recuperada que ingresan en Unidades de Cuidados Intensivos. Su objetivo es disminuir el daño neurológico secundario a anoxia cerebral. Aunque existen múltiples evidencias sobre sus beneficios, el empleo de esta técnica en nuestro país es pobre y todavía existen temas controvertidos como temperatura óptima, velocidad de instauración, duración y proceso de calentamiento. El objetivo de este trabajo es desarrollar la evidencia científica actual y las recomendaciones de las principales guías internacionales. El enfoque de este documento se centra también en aplicación práctica del control estricto de la temperatura en la parada cardiaca recuperada en nuestras Unidades de Cuidados Intensivos Generales o Cardiológicas, principalmente en los métodos de aplicación, protocolos, manejo de las complicaciones y elaboración del pronóstico neurológico.

Targeted temperature management (TTM) through induced hypothermia (between 32-36 oC) is currently regarded as a first-line treatment during the management of post-cardiac arrest patients admitted to the Intensive Care Unit (ICU). The aim of TTM is to afford neuroprotection and reduce secondary neurological damage caused by anoxia. Despite the large body of evidence on its benefits, the TTM is still little used in Spain. There are controversial issues referred to its implementation, such as the optimal target body temperature, timing, duration and the rewarming process. The present study reviews the best available scientific evidence and the current recommendations contained in the international guidelines. In addition, the study focuses on the practical implementation of TTM in post-cardiac arrest patients in general and cardiological ICUs, with a discussion of the implementation strategies, protocols, management of complications and assessment of the neurological prognosis.

Combined Thorax-Abdomen Extraction in Controlled Cardiac Death (Maastricht Type III) Donors.

Donation after circulatory death (DCD) or controlled cardiac death (Maastricht type III donors) is that in which the irreversible cessation of circulatory and respiratory function occurs after the withdrawal of life-sustaining therapies. The shortage of available donor lungs has prompted the development of programs of controlled DCD for lung transplantation. The combined thorax-abdomen extraction in these cases is carried out only in a few centers in Spain, being even more exceptional considering the combined use of super rapid lung extraction with abdominal normothermic regional perfusion. The success achieved with the first cases of combined thorax-abdomen extraction in Maastricht type III donors in Navarra shows that it is a feasible and safe procedure.

Extracción combinada tórax-abdomen en un donante en asistolia tipo III de Maastricht / Combined thorax-abdomen extraction in a Maastricht type III donor

La donación en asistolia (DA) tipo III de Maastricht o DA controlada es aquella en que el cese irreversible de la función circulatoria y respiratoria se produce tras la retirada de medidas de soporte vital. Dada la escasez de pulmones disponibles para trasplante, se está valorando cada vez con más frecuencia el inicio de programas con pulmones procedentes de DA. La extracción combinada tórax-abdomen en DA se lleva a cabo únicamente en doce centros en España, siendo todavía más excepcional el empleo combinado de extracción superrápida pulmonar con perfusión regional normotérmica abdominal. El primer caso de extracción pulmonar y abdominal en un donante en asistolia tipo III en Navarra con este tipo de técnicas de preservación supone un hito y el éxito alcanzado demuestra que es un procedimiento factible y seguro

Donation after circulatory death (Maastricht type III donation) or controlled cardiac death refers to the retrieval of organs for transplantation purposes following death confirmed using circulatory criteria after the withdrawal of life support. The persistent shortfall in organ availability has prompted the development of donation programs following circulatory death for lung transplantation. The combined thorax-abdomen extraction in these cases is carried out in only twelve centres in Spain, while the combined use of abdominal normothermic regional perfusion (NRP) is even more exceptional. The first case of pulmonary and abdominal extraction in a Maastricht type III donor in Navarre with this type of preservation techniques is a milestone and the success achieved shows that it is a feasible and safe procedure

Mortality prediction using TRISS methodology in the Spanish ICU Trauma Registry (RETRAUCI) / Predicción de la mortalidad a través de la metodología TRISS en el Registro Español de Trauma en UCI (RETRAUCI)

OBJECTIVES: To validate Trauma and Injury Severity Score (TRISS) methodology as an auditing tool in the Spanish ICU Trauma Registry (RETRAUCI). DESIGN: A prospective, multicenter registry evaluation was carried out. SETTING: Thirteen Spanish Intensive Care Units (ICUs). PATIENTS: Individuals with traumatic disease and available data admitted to the participating ICUs. INTERVENTIONS: Predicted mortality using TRISS methodology was compared with that observed in the pilot phase of the RETRAUCI from November 2012 to January 2015. Discrimination was evaluated using receiver operating characteristic (ROC) curves and the corresponding areas under the curves (AUCs) (95% CI), with calibration using the Hosmer-Lemeshow (HL) goodness-of-fit test. A value of p < 0.05 was considered significant. Main variables of interest: Predicted and observed mortality. RESULTS: A total of 1405 patients were analyzed. The observed mortality rate was 18% (253 patients), while the predicted mortality rate was 16.9%. The area under the ROC curve was 0.889 (95% CI: 0.867-0.911). Patients with blunt trauma (n=1305) had an area under the ROC curve of 0.887 (95% CI: 0.864-0.910), and those with penetrating trauma (n=100) presented an area under the curve of 0.919 (95% CI: 0.859-0.979). In the global sample, the HL test yielded a value of 25.38 (p = 0.001): 27.35 (p < 0.0001) in blunt trauma and 5.91 (p = 0.658) in penetrating trauma. TRISS methodology underestimated mortality in patients with low predicted mortality and overestimated mortality in patients with high predicted mortality. CONCLUSIONS: TRISS methodology in the evaluation of severe trauma in Spanish ICUs showed good discrimination, with inadequate calibration - particularly in blunt trauma

Objetivos: Evaluar el Trauma and Injury Severity Score (TRISS) como instrumento de auditoría en el Registro Español de Trauma en UCI. Diseño: Evaluación prospectiva de un registro multicéntrico. Ámbito: Trece UCI españolas. Pacientes: Individuos con enfermedad traumática y datos completos ingresados en las UCI participantes. Intervenciones: Comparamos la mortalidad predicha por el TRISS con la observada en la fase piloto del Registro Español de Trauma en UCI desde noviembre de 2012 hasta enero de 2015. La discriminación se evaluó mediante curvas receiver operating characteristic y el valor bajo su área (IC 95%), y la calibración, mediante el test de bondad de ajuste de Hosmer-Lemeshow. Un valor de p<0,05 se consideró significativo. Principales variables de interés: Mortalidad observada y predicha. Resultados: Analizamos 1.405 pacientes. La mortalidad observada fue del 18% (253 pacientes), mientras que la predicha fue del 16,9%. El área bajo la curva receiver operating characteristic fue de 0,889 (IC 95% 0,867-0,911). Los pacientes con trauma cerrado (n=1.305) presentaron un área bajo la curva receiver operating characteristic de 0,887 (IC 95% 0,864-0,910), y aquellos con traumatismo penetrante (n=100), de 0,919 (IC 95% 0,859-0,979). En la muestra global, el test de Hosmer-Lemeshow mostró un valor de 25,38 (p=0,001), siendo de 27,35 (p<0,0001) en trauma cerrado y de 5,91 (p=0,658) en trauma penetrante. La metodología TRISS infraestimó la mortalidad en los pacientes con mortalidad predicha baja y la sobreestimó en pacientes con mortalidad predicha elevada. Conclusiones: La aplicación de la metodología TRISS en el trauma grave ingresado en las UCI españolas mostró buenos niveles de discriminación y una calibración inadecuada, especialmente en el traumatismo cerrado (AU)

Obstrucción esofágica por bezoar relacionada con nutrición enteral / Esophageal obstruction by a bezoar resulting from enteral feeding

Aunque las complicaciones de la nutrición enteral son escasas, nosotros presentamos un caso de obstrucción esofágica durante su administración. Los factores de riesgo para la formación de bezoares van desde trastornos en la anatomía y motilidad del tracto gastrointestinal y utilización de sedantes y analgésicos, hasta la posibilidad de reflujo gastroesofágico acrecentado por la sonda nasogástrica y la posición en decúbito de pacientes ingresados en UCI por períodos prolongados. También parece ser un factor añadido el empleo de dietas que contienen caseína, que precipitan en un medio ácido y la utilización de algunos medicamentos como el hidróxido de aluminio y el sucralfato. En nuestro caso el paciente recibió una dieta con caseína, complementada con fibra y es posible que un reflujo gástrico a esófago por un cardias parcialmente incompetente pudo haber producido la formación de concreciones. Se concluye que lo mejor es la prevención de la formación de bezoares y un mayor control del residuo gástrico en pacientes con factores de riesgo, así como la utilización de sondas nasoduodenales o yeyunales y el empleo de gastrostomía percutánea en pacientes que precisen nutrición enteral por períodos prolongados.
