blood transfusion

A blood transfusion is a medical procedure that involves receiving blood or blood products intravenously. The procedure is performed in a hospital or doctor's office and can take between one and four hours.
Here are some steps that are involved in a blood transfusion:
Consent: The patient is explained the procedure and signs a consent form.
Blood type: A sample of the patient's blood is taken to check their blood type.
Blood delivery: The blood bank delivers the blood once it's ready.
IV line: A needle is inserted into a vein in the patient's arm or hand and connected to an IV line.
Blood transfusion: The blood runs through the IV line into the patient's vein.
Monitoring: The patient is monitored regularly for their pulse, blood pressure, and temperature.
Blood transfusions can help replace blood lost due to surgery or injury. It's important that the correct blood type is used, as the body may reject the new blood if it's not.
Some potential side effects of a blood transfusion include:
Febrile reaction
This can occur during or up to 24 hours after the transfusion and can cause a headache, fever, nausea, chills, and general discomfort.
Allergic reaction
This is the most common reaction and is usually mild, causing itching or hives.
