[Preoperative status of serum proteins in lung surgery patients].

The preoperative serum-protein-status of 91 patients was investigated with a laboratory-screening in order to find out the patients with a malnutrition and consequently with a high risk of postoperative complications. The diagnosis was the basis for the classification in groups. There were no significant differences between values of our patients and normal values of a control group in protein, albumin, prealbumin, transferrin, cholinesterase, alpha-1-antitrypsin and haemopexin. Nutrition parameters are of limited value of preoperative risk-screening in operable lung cancer patients.
