RESUMEN

El estudio tiene el propósito de identificar las alteraciones microcirculatorias en pacientes con sepsis severa en la Unidad de Cuidados Intensivos del Hospital Regional General “Ignacio Zaragoza” ISSSTE; se evaluaron pacientes que ingresaron del 1 abril de 2007 al 30 abril de 2008, entre 18 y 70 años; se excluyeron pacientes con enfermedad pulmonar obstructiva crónica, con apoyo de norepinefrina o dopamina a dosis alfa y con paro cardiaco. Estudio observacional, prospectivo, descriptivo, abierto y longitudinal. 35 pacientes, 18 hombres y 17 mujeres, promedio de 57.8 años, 72.62 kg y 1.65 m. Se calculó el consumo de oxígeno arterial, venoso y capilar, diferencia arteriovenosa de oxígeno, índice de extracción de oxígeno, transporte de oxígeno y consumo de oxígeno en las primeras 24 h de diagnóstico. Se mostraron alteraciones con significancia estadística p ‹ 0.05, excepto el índice de extracción de oxígeno, transporte y consumo de oxígeno. Los resultados corresponden a la bibliografía, en los cuales los cambios en la microcirculación se reflejan antes de las 24 h con alteraciones significativas, caracterizadas por incremento del gasto cardiaco como forma compensadora, disminución de la extracción de oxígeno, disminución del consumo de oxígeno y disminución de la diferencia arteriovenosa de oxígeno.
