“More than four million abdominal surgeries are performed in the US every year and in England about 250,000 abdominal operations are performed per year. Adults undergoing upper abdominal surgery are at an increased risk of postoperative pulmonary complications.
Acute respiratory failure is a relatively common complication after abdominal surgery and is associated with significant morbidity and mortality. According to Michelet 2010, the development of respiratory complication may be explained by two pathological mechanisms.
The first is linked to surgical complications, notably with the occurrence of anastomotic leakage leading to mediastinitis, septic shock, and acute respiratory distress. The second is of medical origin, with multifactorial impairment of respiratory function.”
