[Change in the oxygen regimen in the skin of the extremities after the subcutaneous administration of nitrous oxide].

The work deals with the study of the skin oxygen rate in obliterating diseases of the lower extremities. In 40 patients the skin oxygen tension was studied in the first web space of the foot. 19 of these patients were the control group. In the main group (21 patients) nitrous oxide was injected in the subcutaneous fat of the lower extremities within the complex of the conservative treatment. In obliterating arterial diseases of the lower extremities the disorders of the tissue oxygen rate, particularly pronounced in the late stages of the pathological process, were found. The subcutaneous injections of nitrous oxide improved the regional blood flow in the low extremities.
