During a blood transfusion, allergic reactions may occur due to the blood given. At times, the blood being transfused may have infections due to handling procedures in transport and storage. Therefore, allergies may happen even when the patient is being given the right blood type. Some of the symptoms involved include anxiety, back or chest pain, breathlessness, hypotension, nausea, fever, chills, and dank skin. If the patient experienced a potential delayed reaction, different steps could be taken depending on the severity of the condition.
In mild cases, the transfusion is stopped immediately to assess the patient and administer the necessary medication like an antihistamine. In severe cases, the transfusion is stopped while maintaining the IV line with saline. The medical officer is then contacted, and the patient is given antihistamine or paracetamol, depending on the assessment results. Further investigations are carried out depending on the set procedures of handling such cases.
