Autonomic dysreflexia is an acute syndrome of excessive, uncontrolled sympathetic output that can occur in patients who have had an injury to the spinal cord (generally at or above the sixth thoracic neurologic level). It is caused by spinal reflex mechanisms that remain intact despite the patient's injury, leading to hypertension. This review describes the clinical features of autonomic dysreflexia, its common causes (most frequently stimulation of the lower urinary tract) and a recommended approach to treatment. The condition can nearly always be managed successfully, but prompt recognition is essential--without treatment there may be dire consequences, including death.
自主神经反射异常是一种急性综合征,表现为交感神经输出过度且不受控制,可发生于脊髓损伤(通常在胸段第六神经水平或以上)的患者。它是由脊髓反射机制引起的,尽管患者受伤,但该机制仍保持完整,从而导致高血压。本综述描述了自主神经反射异常的临床特征、常见病因(最常见的是下尿路刺激)以及推荐的治疗方法。这种情况几乎总能成功处理,但迅速识别至关重要——若不治疗,可能会有严重后果,包括死亡。
