Clinical Trial Summary

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.


Description:

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.

Outcome

Type Measure Description Time frame Safety issue
Primary 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
Secondary 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
Secondary Intact skin with no abnormal openings at the site of amputation at 9 months Healed and intact skin at the site of amputation at follow up 9 months. Will be assessed if the wound has not healed at 6 months. Healed amputation is defined as epithelialization of the wound examined by a orthopedic surgeon. 9 months
Secondary Intact skin with no abnormal openings at the site of amputation at 1 year Healed and intact skin at the site of amputation at follow up at 1 year. Healed amputation is defined as epithelialization of the wound examined by a orthopedic surgeon. 12 months
Secondary Time to closed and intact skin at the site of amputation Time to closed and intact skin at the site of amputation is the defined as how many weeks until complete healing of amputation. Healed amputation is defined as epithelialization of the wound examined by a orthopedic surgeon and no abnormal openings. 1 year
Secondary Reamputations The total number of reamputations done within the follow-up period of 1 year. 1 year
Secondary Number of wound revision The total numbers of surgical wound revision done in operating theater. 1 year
Secondary Days in hospital during follow up Total number of days in hospital during 1 year follow up 1 year

Secondary RAND 36-Item Short Form Health Survey RAND 36-Item Short Form Health Survey (SF-36) measures 8 health domains with the total of 36 questions. The domains are physical functioning, bodily pain, role limitations due to physical health problems, role limitations due to personal or emotional problems, emotional well-being, social functioning, energy/fatigue, and general health perceptions. There is also 1 question that measures change in self-perceived health.The question answers is translated to a number between 0 meaning worst selv-perceived health and 100 meaning the best possible quality of health.Each domain will be presented with a number between 0 and 100. baseline
