Crush injuries are types of injury to body parts as result of trauma
Crush injuries range from minor contusions to limb threatening damage. Such injuries involve multiple tissues from skin and subcutaneous tissues, muscles and tendons, bones and joints. In most severe cases, crush injuries lead to known complications including osteomyelitis, non-union of fractures, failed flaps and can also lead to amputations when the situation can be critical.
Trauma plus tissue hypoxia are the common denominators of crush injuries. A severe physical injury entails a condition of acute traumatic ischemia or inadequate supply of blood to various organs. Crush injuries and compartment syndrome are traumatic ischemias associated with complex wounds resulting from traumatic injuries.
Ischemia is a restriction in tissue blood supply, which causes a shortage of oxygen needed for cellular metabolism (to keep tissue alive). Ischemia is generally caused by problems with blood vessels, with resultant damage to or dysfunction of tissue. This can lead to increased edema and vascular compromise thus affection the ability of the tissue to handle infections.
Crush injuries affect a portion of the body, such as the leg, while crush syndrome indicates that the injury is accompanied by a systemic problem, such as shock or failure with various organs.
The damages related to crush injuries:
- Compartment syndrome (increased pressure in an arm or a leg that causes serious muscle, nerve, blood vessel, and tissue damage)
- Fractures, lacerations
- Nerve injury
- Secondary infection
- Smashed fingers
HBOT can provide a better environment for healing and fighting infection
When used as an adjunct to orthopedic surgery and antibiotics, hyperbaric oxygen therapy shows promise as a method to decrease complications from severe crush injuries.
The action of HBOT in crush injuries and compartment syndromes is based on supplementation of oxygen availability.
HBOT supplements oxygen availability to hypoxic tissues during the early post-injury period when perfusion is most likely to be inadequate and also increases tissue oxygen tensions to sufficient levels for the system to function.
HBOT is known to reduce excess fluid in injured area, to increase the supply of oxygen (hyperoxygenation) into the plasma to the damaged, ischemic tissue, reduce swelling and help fight infection to promote healing.
HBOT induces a reduction in blood flow that allows capillaries to resorb extra fluid, resulting in decreased edema. Oxygen is required for all cellular metabolic functions. When oxygen tensions are improved, wound healing and angiogenesis responses are improved.
Hyperbaric Oxygen Therapy has 4 amazing effects on injured body:
- Increases oxygen tension leading to greater capillary oxygen diffusion distances.
- Produces a vasoconstriction that reduces edema formation.
- Has an indirect effect on leukocyte enhancement and increased wound healing.
- Decreases neutrophil adhesion & activation in the ischemic-reperfused tissue.
Hyperbaric oxygen exposures at two atmospheres absolute (ATA) increase the blood oxygen content (the combination of hemoglobin and plasma carried oxygen) by 125 percent. The oxygen tensions in plasma as well as tissue fluids is increased 10-fold (1000 %).(9-11) Sufficient oxygen can be physically dissolved in plasma under HBO2 conditions to keep tissues alive without hemoglobin-borne oxygen.
