Hyperbaric Oxygen Treatment for Necrotizing Fasciitis and Necrotizing Soft Tissue Infections

Hyperbaric Oxygen Treatment for Necrotizing Fasciitis and Necrotizing Soft Tissue Infections

The goal of this clinical trial is to learn if hyperbaric oxygen is beneficial in treating necrotizing infections and decreasing rates of morbidity and mortality. This study therefore has two aims:

1. Determine if hyperbaric oxygen improve morbidity and mortality compared to standard of care using a prospective model.
2. Determine if faster diagnosis to debridement times negate the need for hyperbaric oxygen treatments in necrotizing infections.

Necrotizing fasciitis and necrotizing soft tissue infections are a complicated group of infections dominated largely by polymicrobial infections that rapidly spread through the skin and soft tissues. Secondary effects include vascular occlusion, ischemia, tissue necrosis, along with sepsis and multi-organ involvement. The incidence of necrotizing infections is about 6500 cases annually in the US2. There have been no major advances in disease management over the past twenty years and the mortality still ranges in the 10-43 % range2. Today early aggressive debridement and IV antibiotics remain the cornerstone of treatment. Hyperbaric oxygen has been shown in several case studies and retrospective studies to possibly improve mortality and morbidity in this patient population.1-4 One limitation of prior studies is many of them are retrospective. Additionally, not all centers are able to take patients quickly back for surgical debridement which could increase rates of morbidity and mortality. Corewell Health West Butterworth Hospital has 24/7 in-hospital acute care surgery services. This allows very short diagnosis to OR debridement wait times in necrotizing infections. This study therefore has two aims: first is to determine if hyperbaric oxygen improve morbidity and mortality compared to standard of care using a prospective model. Secondly, to determine if faster diagnosis to debridement times negate the need for hyperbaric oxygen treatments in necrotizing infections.

Inclusion Criteria:

• Patient or advocate is able to sign consent

Exclusion Criteria:

• Pediatric patients
• Pregnant patients
• Patients deemed unlikely to survive or unable to go to surgical debridement
