Crush injuries occur when body tissues are severely traumatized such as in motor vehicle accidents, falls, and gun shot wounds. These injuries frequently occur in the extremities. When crush injuries are severe, the rate of complications such as infection, non-healing of fractures, and amputations range up to 50%.
When used as an adjunct to orthopedic surgery and antibiotics, hyperbaric oxygen (HBO2) therapy shows promise as a way to decrease complications from severe crush injuries. HBO2 increases oxygen delivery to the injured tissues, reduces swelling and provides an improved environment for healing and fighting infection.
Hyperbaric oxygen treatments should be started as soon after an injury as possible. They are usually continued for 5 to 6 days. A number of related conditions, including compartment syndromes, thermal burns, and threatened replantations are also benefited by hyperbaric oxygen, as discussed in other sections in this site.

ACUTE TRAUMATIC PERIPHERAL ISCHEMIA
Note: Within the Medicare 35-10 "Covered Conditions" listing are three conditions for which the rationale for HBO therapy is essentially identical. These conditions involve different etiologies but the net insult will frequently follow the common pathway of :acute ischemia; tissue hypoxia; threatened tissue viability; necrosis; reperfusion injury, and threatened limb loss.
These conditions are:
· Acute Traumatic Peripheral Ischemia
· Crush Injuries, and Suturing of Severed Limbs.
· Acute Peripheral Arterial Insufficiency
As a consequence of this common disease pathway, the supportive literature provided below can serve as representative of all three conditions.

A placebo-controlled randomized and blinded clinical trial in acute limb-threatening trauma to the extremities. Statistically significant improvement in outcome occurred in the HBO group. HBO therapy improved wound healing, reduced the number of surgical procedures, and likewise reduced the number of amputations that became necessary.

Using modern-day laboratory techniques, this work provides firm morphologic evidence of the beneficial effect of HBO therapy on microcirculatory perfusion in ischemia-reperfusion injury. HBO therapy is observed to protect the microcirculation from an otherwise post ischemia reperfusion injury.
