Local cryotherapy (hyperbaric chamber of active hyperemia) is a treatment method that involves exposure to a specific area of the body with cold. The patient removes clothing from the affected area. Nearby areas are covered with a blanket. The time of exposure to dry cold to the treatment area is 2-6 minutes, the course of procedures is 10-12. After the end of the procedure, the affected area is wrapped with a blanket until there is a feeling of warmth in the tissues. The main therapeutic effect of local cryotherapy is to reduce swelling and pain in the patient through increased heat exchange.
Therapy is contraindicated in peripheral vascular diseases in which arterial circulation is impaired (endarteritis, obliterating atherosclerosis of peripheral vessels, Raynaud's disease); thrombophlebitis; systemic blood diseases; cold intolerance. It is also contraindicated for children under five years of age.
