Abstract
Elevation of SGO-T in surgical patients, as in any others, and as with any other laboratory procedure, must be correlated with the total clinical situation. In most surgical patients, significant elevation may be considered to be reliable as an aid in the diagnosis of myocardial infarction. Notable exceptions to this are patients undergoing surgery of the biliary tract, where SGO-T levels are unreliable for this purpose during the first 2 postoperative days. Elevation of SGO-T must be interpreted with caution as evidence of myocardial infarction in surgical patients suspected of having liver disease, including metastatic carcinoma. Elevations in the course of amputation and of cardiac surgery are probably also unreliable. Protracted surgical shock may produce elevation of considerable magnitude, beyond that usually seen in myocardial infarction.
