Respiratory Physiopathology in Surgical Repair for Large Incisional Hernias of The Abdominal Wall

Abstract

The intraoperative assessment of respiratory mechanics is useful to evaluate and eventually to decrease the mechanical workload (prosthesis widening peritoneum or fascia incisions). The passive mechanical work performed by the ventilator needs to be kept constant or no higher than 10% basic data: if these conditions are maintained, mostly in patients with COPD, there is no risk of respiratory muscular fatigue during the postoperative period.
