Blood transfusion is conducted if an individual lost blood from an injury, during surgery, or from a medical condition that affects blood or blood components. The blood transfusion is a common medical procedure that replaces the lost blood or blood components through an intravenous line.
The blood or blood components used for blood transfusion usually came from donors. Transfusions are a low-risk, safe treatment provided by blood banks and healthcare facilities.
Complications rarely occur after blood transfusions. If problems do arise, they are usually minor.
A blood transfusion can supply specific blood components, or parts, in addition to whole blood. Blood consists of various components, including:
A transfusion gives the patient the component or parts of blood they require. Red blood cells are the most often transfused blood type. Receiving whole blood, which contains all its components, is also an option, but whole blood transfusions are infrequent.
The person’s life may be saved by a blood transfusion. If they have had blood loss due to an injury or surgery, or if they suffer from any of the following medical problems, they may require a blood transfusion:
The medical community puts a lot of effort into ensuring that blood used for transfusions is safe. Blood banks inquire about the health, habits, and travel history of potential donors. Blood donations are only accepted from those who meet the standards for blood donors. Blood donations are tested in accordance with national protocols. Blood is disposed of if there is any doubt as to its safety.
Blood banks monitor and screen donors to lower the risk of diseases associated with blood transfusions; as a result, diseases like HIV and hepatitis B or C are very uncommon.
Blood transfusions can cause a number of reactions in people. Among the reactions people could have are:
These reactions do not occur in most people and they typically feel like allergies when they do occur. Inform the healthcare provider if a patient exhibits unusual symptoms while receiving a transfusion. Relief may be obtained by stopping the transfusion or by taking particular medications.
Donated blood or blood components are kept in specialized medical containers until they are required. An intravenous line comprised of tubing is attached to the required blood bag by the healthcare provider. The delivery of blood or blood components into the circulatory system starts when the needle at the end of the tube is placed into a vein.
Typically, blood transfusions take place at a hospital, outpatient clinic, or healthcare provider’s office. Depending on which blood components the patient needs and how much blood they receive, the treatment usually takes one to four hours.
Prior to a transfusion, the blood will be analyzed to identify if it is Rh positive or Rh negative and to identify whether the blood type is A, B, AB, or O. The donated blood used in the transfusion needs to match the recipient’s blood type.
The following steps are conducted before the procedure:
The following steps are followed while the blood transfusion is ongoing.
When the blood transfusion has been completed, the nurse will take out the IV line and needle. The bruise that may form around the injection site will likely go away in a few days for the patient.
The patient should contact their healthcare provider if they developed dyspnea, chest discomfort, or back pain, days after the transfusion.
The patient may be at risk of death if they don’t have enough blood or one of the components of blood. Blood transfusion is essential for this reason.
Unexpected reactions to a blood transfusion might occur. A patient may respond during the transfusion, the day following, or even months later. If a patient has any of the following, contact the healthcare provider immediately away:
