The use of hyperbaric oxygenation in postoperative treatment of obliterating arterial disease of the lower extremities undergoing vascular reconstructive surgery

Abstract

Background. Hyperbaric oxygenation is successfully used in the treatment of many diseases accompanied by hypoxia. The purpose of this work was to study the oxygen balance in patients with obliterating arterial disease of the lower extremities who received hyperbaric oxygen along with usual therapy following reconstructive vascular surgery. Material and methods. 18 patients with obliterating arterial disease of the lower extremities were studied. Measurements were taken using gasometry and tetrapolar rheography. On the basis of arterial blood oximetry data and cardiac output indicators, determined reographically, volumetric indexes of delivery and consumption of the oxygen by the body and the volume of intrapulmonary bypass of blood were calculated. Results. Inclusion of hyperbaric oxygenation as five 45-minute sessions at a pressure of 1.5 atm in the postoperative intensive care of patients with obliterating arterial disease of the lower extremities, undergoing reconstructive vascular surgery, was found to lead to significant improvements in the oxygen balance of the body, increasing the oxygen transport capacity of the blood, increasing the physiological reserve of organs and systems of the body and aligning of the metabolic processes of the tissues. Conclusions. Hyperbaric oxygenation can be successfully used in the postoperative treatment of patients with obliterating arterial diseases of the lower extremities undergoing vascular reconstructive surgery.
