[Dynamics of the level of plasma myoglobin in oncology patients with and without complications in the postoperative period].

Initial hypermyoglobinemia was found in patients with cancer of lungs, large intestine and rectum. Within early postoperational period under favourable conditions moderate increase in content of free myoglobin was detected, most pronounced in patients with lung cancer. Maximum concentration of myoglobin was estimated within first postoperational day, normalization occurred within 3-4 days after the operation. In patients with postoperational complications (peritonitis, pneumonia, sepsis, etc) increase in content of myoglobin was more distinct (1.6-2-fold) and was maintained within the longer period. Increase in content of blood plasma myoglobin occurred usually before manifestations of clinical symptoms related to postoperational complications.
