RESUMEN
Objetivo: Detectar tempranamente cambios en los niveles de la presión gástrica de CO
2, durante la hipoperfusión en pacientes quirúrgicos con sepsis.
Diseño: Estudio prospectivo, longitudinal, descriptivo, observacional, de cohorte.
Sitio: Unidad de Terapia Intensiva de Hospital Central Norte de PEMEX, ciudad de México.
Pacientes: 42 pacientes sépticos con APACHE II mayor de 13 puntos, con edad entre 18 y 99 años, de ambos sexos, que fueron sometidos a procedimiento quirúrgico abdominal, a quienes se les instaló sonda de tonometría gástrica de fase aérea.
Intervenciones: Con el propósito de detectar y tratar de forma oportuna la hipoperfusión en pacientes quirúrgicos con sepsis, se monitorizó la presión gástrica de CO
2 mediante una sonda de tonometría.
Mediciones y resultados: Se midieron presión gástrica de CO
2 (PgCO
2), pH gástrico (pHi), diferencia de presión de CO
2 gástrica y al final de la espiración [P (g-et) CO
2], observamos que la mayoría de los pacientes estudiados tuvieron un incremento en la acidez gástrica.
Conclusiones: La tonometría gástrica de fase aérea es una poderosa herramienta de mínima invasión que detecta alteraciones en la perfusión regional y predice complicaciones y mortalidad en pacientes quirúrgicos con sepsis.
