Dynamic study of oxyhemoglobin in traumatic shock.

Abstract

The dynamic study of oxyhemoglobin in general, and especially in traumatic shock, represents one of the aspects of pathophysiology which is of interest to practitioners as well as to pathophysiologists due to its relatively practical accessibility. The study was performed on two groups of 30 subjects: a healthy subjects group and a control group. The patients hospitalized in the Intensive Care Section of the Clinical Hospital Department of Constanţa represented the subjects of the control group. Using an Oximeter--AVL 912 oxylite, the arterial hemoglobin oxygen saturation, venous hemoglobin oxygen saturation and the calculation of arterio-venous oxygen difference were measured in their dynamics. The results showed a diminution of oxygen extraction at the tissular level. We also noticed a good correlation between oxyhemoglobin dynamics and the evolution of the patients during specific therapy.
