Resumen

La obesidad es una enfermedad creciente, aceptada ya como epidemia con prevalencias de 25% en países desarrollados, es un importante factor de riesgo para complicaciones mayores, morbilidad y mortalidad relacionada con los procedimientos de intubación y ventilación en la unidad de cuidados intensivos (UCI). Esta revisión narrativa presenta el impacto de la obesidad en el sistema respiratorio y da puntos clave para optimizar el manejo de la vía aérea, la ventilación mecánica invasiva y no invasiva en pacientes con obesidad en la UCI. Se debe optimizar primero la posición del cuerpo con la posición de Trendelenburg inversa o la posición sentada.

La ventilación no invasiva (VNI) se considera la terapia de primera línea en pacientes con obesidad que tienen insuficiencia respiratoria aguda postoperatoria. La preoxigenación con presión positiva antes del procedimiento de intubación es el método de referencia.  El uso de videolaringoscopia debe ser considerado por intensivistas adecuadamente entrenados, especialmente en pacientes con varios factores de riesgo.

Sobre la ventilación mecánica en pacientes con y sin dificultad respiratoria aguda (SDRA) el uso de bajo volumen tidal (6 ml/kg de peso corporal) y moderado a alto PEEP titulado de ser posible, con cuidadosa maniobra de reclutamiento en pacientes seleccionados. El posicionamiento prono es una terapéutica de elección en pacientes con SDRA grave y obesidad. Se debe considerar la VNI profiláctica después de la extubación para evitar reintubación. Aún queda por definir si la obesidad paradójica son fenotipos de esta población, si la medición seriedad de la presión intra abdominal y transplumonar pudiesen personalizar el manejo.
