Additional methods of treatment, such as dilatation of blood vessels by oral medication of nerve (sympathetic ganglion) blocks and the use of anticoagulants, have not proved especially valuable. The gangrenous area will become fully demarcated after about a month, and no attempt at amputation should be performed earlier. In summary, frostbite is better prevented by proper clothing and footwear and by adequate food and liquid intake. Should it occur, turn back early before extensive damage results. Treatment should be instituted in an appropriate camp rather than on the trail and should include rapid thawing; the gentle handling and cleansing of tissues to prevent further damage and infection; the prophylactic use of antibiotics; and general supportive measures determined by the patient's condition, shock, and other injuries. Walking on thawed frostbitten feet and premature "surgery" must be avoided. If nothing can be done, at least protect the part from further cold and allow it to thaw slowly by itself. |
