Lack of People to follow up the study, work overload

The aim of this study is to see weather hyperbaric oxygen treatment is beneficial as adjuvant treatment for frost damage.

The investigators hope to include at least 20 patients in a randomized manner. Half of the patients are randomized to hyperbaric oxygen, and half of the patients are randomized not to have hyperbaric oxygen treatment.

Under hypotheses: The number og surgeries is reduced by hyperbaric oxygen treatment as adjuvant treatment for frost damage. The functional level of the frost damaged patient is better after 6 and 12 months when also treated with hyperbaric oxygen treatment for frost damage.

Inclusion Criteria:

• Age 18-70. Frost damage grade II-IV. Inclusion is needed within 48 hours from time of damage.

Exclusion Criteria:

• Pregnancy. Ventilator treatment. Problems with equalizing. High grade heart failure. Chronic obstructive lung disease of high grade. Treatment over 3 days after time of damage. Serious claustrophobia/psychiatric illness.
