ABSTRACT
Postcardiotomy cardiogenic shock represents the most serious expression of low cardiac output syndrome after cardiac surgery. Although infrequent, it is a relevant condition due to its specific and complex pathophysiology and important morbidity-mortality. The diagnosis requires a high index of suspicion and multimodal hemodynamic monitoring, where echocardiography and the pulmonary arterial catheter play a main role. Early and multidisciplinary management should focus on the management of postoperative or mechanical complications and the optimization of determinants of cardiac output through fluid therapy or diuretic treatments, inotropic drugs and vasopressors/vasodilators and, in the absence of a response, early mechanical circulatory support. The aim of this paper is to review and update the pathophysiology, diagnosis and management of postcardiotomy cardiogenic shock (AU)
El shock cardiogénico poscardiotomía representa la situación clínica más grave del síndrome de bajo gasto poscirugía cardiaca. Aunque infrecuente, su fisiopatología específica y compleja y su elevada morbimortalidad lo convierten en una entidad especialmente relevante en el contexto de la medicina intensiva. El diagnóstico requiere un elevado índice de sospecha clínica y monitorización multimodal, con un papel fundamental para la ecocardiografía y el catéter de arteria pulmonar. Su manejo debe ser precoz, escalonado y dinámico, multisistémico, multidisciplinar, basado en resolver potenciales complicaciones mecánicas y optimizar los determinantes del gasto cardiaco mediante aporte de volumen o tratamiento deplectivo, fármacos inotrópicos y vasopresores/vasodilatadores y, en ausencia de respuesta, soporte circulatorio mecánico precoz. El objetivo de este artículo es presentar una revisión narrativa y una actualización de la fisiopatología, el diagnóstico y el manejo clínico del shock poscardiotomía. Además, se proponen pautas de actuación que faciliten el manejo clínico diario (AU)
