Prognostic nutritional index in gastrointestinal surgery.


Based on assessment of 161 nonemergency general surgical patients, a multiparameter index of nutritional status was defined relating the risk of postoperative complications to baseline nutritional status. When applied prospectively to 100 gastrointestinal surgical patients, this index provided an accurate, quantitative estimate of operative risk, permitting rational selection of patients to receive preoperative nutritional support.
