Paciente con antecedente de obesidad mórbida intervenida de urgencia de isquemia intestinal bajo anestesia general. Durante el postoperatorio en la Unidad de Reanimación, tras conseguir estabilidad hemodinámica, se procede a la extubación con colocación de Ventilación no invasiva en modo presión de soporte. A las 24 horas se observa un fracaso respiratorio secundario a hipoventilación, con acidosis respiratoria, aumento del trabajo respiratorio y fatiga muscular. Se plantea la reintubación de la paciente ante la mala evolución, decidiéndose finalmente por cambio de modo ventilatorio al modo AVAPS (Average Volume – Assured Pressure Support Ventilation), observando mejoría gasométrica y en la mecánica ventilatoria.
The patient is a morbidly obese woman undergoing urgent surgery for acute intestinal ischemia under general anesthesia. During the postoperative period in the reanimation unit, after being stabilized, she was extubated and non-invasive pressure support ventilation was started. After 24h, the patient developed a respiratory failure secondary to hypoventilation, with respiratory acidosis and failure of the respiratory pump. Regarding the patient’s situation, reintubation was considered but finally the decision was made to change the non-invasive ventilation mode into AVAPS (Average Volume – Assured Pressure Support Ventilation), which was successful and a gasometrical improvement of parameters was achieved.
