Protein depletion was associated with higher pneumonia rates and longer stays after GI surgery; leaves open whether preoperative repletion improves outcomes.
Does preoperative protein depletion increase the risk of postoperative pneumonia in patients awaiting major elective gastrointestinal surgery?
Preoperative protein depletion is associated with impaired respiratory function and is a significant risk factor for postoperative pneumonia and prolonged hospital stay in patients undergoing major gastrointestinal surgery.
Windsor et al. (1988) studied this question.
