KINETICS OF ACID-ALKALINE STATE PARAMETERS DURING PERIOPERATIVE VOLEMIC SUPPORT
Objective - identification of the kinetics of the acid-alkaline blood composition of patients in the implementation of various models of perioperative volemic compensation. Materials and methods. The study was performed in 80 patients graded into two groups depending on the model of perioperative volemic compensation. The patients were evaluated for the acid-alkaline and electrolyte composition of venous blood, followed by their statistical treatment. Results. In patients of groups I and II, significant changes in the studied criteria of the acid-base state of venous blood were recorded throughout the follow-up period. This was also stated by a multiple comparison, which recorded a stable difference between BEb and BE ecf., as well as the pH of venous blood between the studied time intervals in patients of groups I and II. The identical situation was observed in the studied patients by the content of chlorine in venous blood. Notably, during the follow-up period, group I and group II patients recorded a credible discount between parameters of acid-alkali and electrolyte blood composition. This fact indicated the dominant kinetics of exponents of acid-alkaline and electrolyte blood composition of patients of groups I and II when implementing various models of perioperative volemic compensation. Conclusion. The implementation of perioperative volemic compensation with Ringer's solution initiates the onset of inverted metabolism and acidification of blood in patients. Counterfeiting in the liquid supply scheme of sterofundin isotonic, unlike Ringer's solution, advantageously reforms the acid-base state of the venous blood of patients.
