Common complications associated with blood and blood component administration are detailed below: ●​ Febrile Reactions : These are the most frequently encountered adverse reactions during blood transfusions. While they can occur with any blood product, they are most commonly associated with packed red blood cells and are typically not accompanied by hemolysis. Signs and symptoms of a febrile reaction include fever, nausea, anxiety, chills, and warm, flushed skin. ●​ Hemolysis : This results from an incompatibility between the donor's and recipient's blood, often referred to as ABO incompatibility. This incompatibility can arise from errors in the laboratory's typing and cross-matching processes or mistakes in verifying the blood and matching it to the client's blood type. Indicators of hemolysis include flank pain, chest pain, restlessness, oliguria or anuria, respiratory distress, brown urinary output, hypotension, fever, low blood pressure, and tachycardia. ○​ Treating hemolysis involves administering normal saline after discontinuing the transfusion and changing all tubing to prevent kidney failure and circulatory collapse. Although rare, a delayed hemolytic reaction can occur up to about 4 weeks after the transfusion, characterized by jaundice, discolored urine, and anemia. ○​ Intravenous tubing, blood filter, and the blood bag with its remaining contents are retained and sent to the laboratory for evaluation. Samples of the client's blood and urine are also taken for diagnostic testing. ●​ Allergic Reactions : Allergic reactions to blood transfusions can vary in severity. Mild allergic reactions typically result from an allergy to plasma proteins in the blood, while severe reactions stem from a severe antibody-antigen response. Mild allergic reactions may include itching, pruritic erythema, swelling of the lips, tongue, pharynx, eyelids, and flushing of the skin. Severe allergic reactions can manifest as chest pain, decreased oxygen saturation, loss of consciousness, flushing, shortness of breath, and respiratory stridor. These can be managed with corticosteroids and/or antihistamines, while severe reactions necessitate supplemental oxygen and medications. In some cases, a severe allergic reaction can be life-threatening. ●​ Sepsis : This is characterized by fever, hypotension, oliguria, chills, nausea, and vomiting and occurs as a result of contamination in the blood. Treatment involves administering intravenous fluids and antibiotics. As with hemolytic reactions, the intravenous tubing, blood filter, and the blood bag with its remaining contents are retained and sent to the laboratory. Samples of the client's blood and urine are also collected for diagnostic testing.
