输血反应越早发现并及时处理,则对受血者造成的损失可能越少。因此,必须注意早期诊断问题。输血的即刻反应可表现为寒战、发热、胸紧、背痛、心悸、恶心、呕吐、呼吸困难、支气管痉挛、血压下降、心力衰竭、肺水肿、血红蛋白尿、荨麻疹及血管神经性水肿等。这些症状虽无特异性,但若发生在输血过程中,应考虑与输血反应有关。 The earlier the transfusion reaction is found and treated promptly, the less damage the recipient may cause. Therefore, we must pay attention to the early diagnosis of the problem. Transfusion of immediate response can be expressed as chills, fever, chest tightness, back pain, palpitations, nausea, vomiting, dyspnea, bronchospasm, decreased blood pressure, heart failure, pulmonary edema, hemoglobinuria, urticaria and angioneurotic edema. Although these symptoms are non-specific, but if occurred in the transfusion process, should be considered with the transfusion reaction.
