Cold Injuries

Diagnostic, Preventive & Treatment Protocols

Severity of cold injuries is difficult to evaluate clinically and may take several weeks before final judgment can be made. Often, mild-looking lesions may develop into severe frostbite and florid lesions heal without any tissue loss. Considering the large number of victims (defence personnel and civilians) of cold injuries, the human and economic cost is significant. DRDO has established and standardised scintigraphy as a gold-standard method to define the areas of ischemia, dead tissue and salvageable tissue in cold-injury lesions. Serial study can predict treatment response with a high degree of accuracy. Apart from INMAS, the facility is available at PGIMR, Chandigarh, for the benefit of defence personnel.

DRDO has successfully introduced Aloevera cream for treating cold injuries in combination with pentoxiphyllin, aspirin and tea decoction. Four new allopathic ointments have also been developed for preventing and treating cold injuries. These are useful in different degrees of cold injuries and act for different periods for preventive or treatment use. The ointments neutralise the ischemia, reduce pain, restore circulation and promote healing. Apart from cold injuries, they have a number of other applications also. Increase of 30-120 per cent in circulation was confirmed using nuclear medicine imaging. User trial is planned in collaboration with District Administration, Keylong.
