[Characteristics of several indicators of colloid-osmotic homeostasis in middle-aged and aged persons]

Basic indexes of colloid-osmotic homeostasis have been studied in 50 patients. 25 elderly and old patients without surgical pathology have been examined, 25 young healthy persons were controls. It has been found that in elderly patients blood plasma COP tends to decrease, while blood plasma osmolality increases. The nature of changes gives evidence of lower reliability of colloid-osmotic homeostasis in geriatric patients. The results show that it is unjustified to use standard values of colloid-osmotic homeostasis characteristic of young and middle-aged patients during infusion therapy in geriatric patients.
