Osteomyelitis
Septic inflammatory bone disease - that can be due to direct trauma,
surgery or hematogenous spread infection.
Bacterial
infection promotes ischemia and hypoxia to develop
which
interferes with local perfusion, function of white blood cell to kill
bacteria, bone cells activity in removing dead infected bone and
fibroblastic function of collagen synthesis. Finally hypoxia
limits antibiotics therapeutic function (inability to penetrate pus and
inactivate microorganisms in condition of low oxygen tension).
Clinical symptoms:
local (wound infection with erythema, heat, swelling, tenderness,
pain and drainage)
systemic (septic fever , chills, dehydration, lethargy and some organ
failure such as renal failure ).
Clinical application of HBO:
- HBO raises the tissue oxygen tension and provide adequate
oxygen supply to infected area
- HBO enhances the leukocyte killing mechanism (phagocytosis)
- HBO provides adequate oxygen for new vessels formation
(fibroblast activity leading to angiogenesis
- HBO speeds up new bone formation (osteogenesis)
- HBO helps in removing necrotic bone (osteoclastic function)
- HBO enhances antibiotics activity
- HBO in generally boosts up immune system (increases
capacity of WBC to fight infection) and provides faster recovery.
