Reperfusion injury, sometimes called ischemia-reperfusion injury (IRI) or reoxygenation injury, is the tissue damage caused when blood supply returns to tissue (re-+ perfusion) after a period of ischemia or lack of oxygen (anoxia or hypoxia).
[5] [6] It is a reperfusion injury that appears after the release of the crushing pressure. The mechanism is believed to be the release into the bloodstream of muscle breakdown products—notably myoglobin , potassium and phosphorus —that are the products of rhabdomyolysis (the breakdown of skeletal muscle damaged by ischemic conditions).
Reperfusion therapy is a medical treatment to restore blood flow, either through or around, blocked arteries, typically after a heart attack (myocardial infarction (MI)). Reperfusion therapy includes drugs and surgery. The drugs are thrombolytics and fibrinolytics used in a process called thrombolysis.
Reperfusion injury, i.e., postpulmonary thromboendartectomy or lung transplantation Swimming induced pulmonary edema also known as immersion pulmonary edema [ 23 ] [ 24 ] [ 25 ] Transfusion associated Acute Lung Injury is a specific type of blood-product transfusion injury that occurs when the donors plasma contained antibodies against the ...
Restoration of blood supply to ischemic tissues can cause additional damage known as reperfusion injury that can be more damaging than the initial ischemia. Reintroduction of blood flow brings oxygen back to the tissues, causing a greater production of free radicals and reactive oxygen species that damage cells.
Ischemia-reperfusion (IR) tissue injury is the resultant pathology from a combination of factors, including tissue hypoxia, followed by tissue damage associated with re-oxygenation. IR injury contributes to disease and mortality in a variety of pathologies, including myocardial infarction , ischemic stroke , acute kidney injury , trauma ...
The cause of TRALI is currently not fully understood. 80–85% of cases are thought to be immune mediated. [5] [6] Antibodies directed toward human leukocyte antigens (HLA) or human neutrophil antigens (HNA) have been implicated, with transfused antibodies shown to bind antigens expressed on pulmonary endothelial cells to initiate acute inflammation in the lungs.
Lung diseases, cardiac shunts, and smoking can cause a ventilation–perfusion mismatch that results in significant symptoms and diseases; treatments include bronchodilators and oxygen therapy. Diagram of anatomy of pulmonary alveolar structure Diagram of anatomy of lung structure
