This study evaluates the effect of additional hyperbaric oxygen therapy after lower extremity amputation. The patients will be randomized after amputation to either a treatment group receiving hyperbaric oxygen therapy, or control group.
Hyperbaric oxygen therapy has been used to treat hard to heal wounds for decades. Amputation, especially distal lower extremity amputations have the same problem with healing and patients often need to be re-amputated more proximally. In these patients oxygen levels are often the decisive factor. Providing additional oxygen under hyperbaric conditions will increase tissue oxygen concentration sufficient for the amputation stump to heal. This will give the patients a more distal amputation with better condition for ambulation.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Hyperbaric oxygen therapy | Experimental | 30 sessions of Hyperbaric oxygen therapy, 90min treatment at 2,4 ATA(atmosphere absolute) with 100% oxygen.First session must be given within 7 days after initial amputation. Treatment is given as outpatient treatment after discharge from hospital. |
|
| Control group | No Intervention | Control group will be given standard of care with follow up at the outpatient clinic after discharge from hospital. |

| Measure | Description | Time Frame |
|---|---|---|
| Intact skin with no abnormal openings at the site of primary amputation | Healed and intact skin at the site of primary amputation without need for more proximal amputation.Healed amputation is defined as epithelialization of the wound examined by a orthopedic surgeon. Level of primary amputation is decided by the surgeon. Planned 2-session amputation, for example Guillotine amputation with a final amputation later is considered being primary amputation. Healed primary amputation will be measured at 12 weeks. | 12 weeks |

| Intact skin with no abnormal openings at the site of amputation at 6 months | Healed and intact skin at the site of amputation at follow up 6 months. Healed amputation is defined as epithelialization of the wound examined by a orthopedic surgeon. | 6 months |
| Intact skin with no abnormal openings at the site of amputation at 9 months |
