[Role of heat flow generated by an abdominal cavity in monitoring of acute surgical pathology of abdominal organs].

Despite of significant development of modern surgery results of treatment of acute diffused peritonitis and acute intestinal obstruction are still unsatisfactory. Successful treatment of these conditions depends considerably on timely and adequate diagnosing as it gives a choice of optimal treatment tactics. Measuring of a human body heat flow in areas of organs affected by pathology in cases of acute diffused peritonitis and acute intestinal obstruction provides a possibility to improve the principles of early differential diagnosing, to form new approaches to treatment tactics and monitoring of general health status of a patient during early postoperative treatment. 47 patient suffering from acute diffused peritonitis and 42 patients suffering from acute intestinal obstruction have been examined; the patients were divided into groups based on abdominal cavity exudates character, intestinal obstruction type and intra-abdominal hypertension grade. Measurement of abdominal cavity heat flow was performed by a contact method with use of thermoelectric medical thermometer. Intra-abdominal hypertension was measured by generally used transvesical method. It has been established that abdominal cavity heat flow correlates with character of abdominal cavity exudates; this is also confirmed by reliable difference between serous peritonitis and fibrinopurulent peritonitis indices. Indices in case of acute intestinal obstruction are lower than ones in case of acute diffused peritonitis as there are no inflammatory changes of peritoneum. Development of intra-abdominal hypertension of grades 3-4 directly influences the heat flow extent; this is explained by accelerated and aggravated pathological changes of inner organs cased by the main disease. Thus, abdominal cavity heat flow fully reflects degree of purulent and inflammatory processes of abdominal cavity organs and can be used for additional diagnosing and clinical course monitoring.

[Changes of biochemical content of the duodenal mucosa in early recurrence of bleeding].

Using the duodenal bleeding and its early recurrence modelling on 48 mongrel dogs the dynamics of content of general protein, urea and glucose in duodenal mucosa were investigated. There was established that the dynamics of investigated indices of anterior and posterior duodenal wall appeared different and that the level of urea while early recurrence of duodenal bleeding owes consistent tendency for lowering, especially in posterior duodenal wall. The glucose level in these both walls is merely stable.

[Changes of duodenal biochemical content in the early duodenal recurrent hemorrhage].

The dynamics of the indices changes concerning the general protein, urea and glucose content was investigated in 32 mongrel dogs while modelling the hemorrhage from duodenum and its early recurrence. There was established that the urea content and somewhat the general protein content reflect most accurately the hazard of the early recurrent hemorrhage occurrence.
