can a blood transfusion cause anaphylactic shock
They may cause death if they block a major artery, such as the large pulmonary artery that runs through the lungs. They also may cause tissue to die if they prevent blood flow to the area.
A foreign object such as a bit of tissue or air circulating in the blood is known as an embolus. Emboli can travel through the blood vessels and may cause blockages leading to tissue damage, organ malfunction, or more serious conditions, such as pulmonary embolism or stroke.
If there is a clot in the leg, a DVT (deep vein thrombosis), when it breaks loose it could cause a pulmonary embolus, which is a medical emergency, and if severe enough could cause death.
When a clot breaks loose and circulates through the bloodstream, it is called an embolus. If the embolus travels to the lungs, it can cause a pulmonary embolism, while if it lodges in a blood vessel in the brain, it can lead to a stroke. This process can pose serious health risks and requires prompt medical attention.
The blood given by transfusion must be matched with the recipient's blood type. Incompatible blood types can cause a serious adverse reaction (transfusion reaction). Blood is introduced slowly by gravity flow directly into the veins
Blood clots can move, if they are inside a blood vessel. Moving blood clots are dangerous since they might cause a blockage of the blood flow at some critical location, causing a heart attack or stroke.
No, blood cannot be drawn during a transfusion as the purpose of a transfusion is to provide blood to the patient, not to remove blood from them. Drawing blood during a transfusion would disrupt the process and potentially cause harm to the patient.
Decreased pulmonary blood flow alone does not cause cyanosis. It is when decreased pulmonary blood flow is associated with right to left shunting (ie Tetralogy of fallot) that it is associated with cyanosis.
PYROGEN
An embolus is a physical mass (fat, air, blood clot, etc) which can travel to a different location in the arteries. An embolism is when an embolus actually blocks a capillary. A thrombus is a physical mass which remains attached to it's site of origin. A thrombus may detach to become a thrombo-embolus which may then cause an embolism.
Transfusion reaction may also cause a hypersensitivity of the immune system that, in turn, may cause tissue damage within the patient's body.
