Clinical Description

Overview of Rh Incompatibility

Rh incompatibility occurs when an Rh-negative individual receives Rh-positive blood. The Rh factor is a protein that can be present on the surface of red blood cells. If an Rh-negative person is exposed to Rh-positive blood, their immune system may recognize the Rh factor as foreign and produce antibodies against it. This immune response can lead to various complications, particularly in transfusion settings.

Symptoms and Reactions

The symptoms of Rh incompatibility reactions can vary in severity and may include:

• Fever: A common initial response to transfusion reactions.
• Chills: Often accompanying fever, indicating an immune response.
• Back pain: A potential sign of hemolytic reaction.
• Dark urine: Resulting from hemolysis of red blood cells.
• Shortness of breath: May occur due to hemolytic anemia or fluid overload.
• Hypotension: A drop in blood pressure can occur in severe cases.

Mechanism of Reaction

The reaction occurs when the recipient's immune system attacks the transfused Rh-positive red blood cells. This can lead to hemolysis (destruction of red blood cells), which can cause complications such as:

• Acute hemolytic transfusion reaction: This is a serious and potentially life-threatening condition that can occur within minutes to hours after transfusion.
• Delayed hemolytic reaction: This may occur days to weeks after the transfusion, often with milder symptoms.

Diagnosis and Management

Diagnosis

Diagnosis of an Rh incompatibility reaction typically involves:

• Clinical History: Reviewing the patient's transfusion history and symptoms.
