Question

Quizplus · Accepted Answer

Autonomic hyperreflexia syndrome (AHS) is a potentially life-threatening medical emergency that can occur in patients with spinal cord injuries above the level of T6. It is characterized by a sudden and dangerous increase in blood pressure, usually above 200/100 mmHg, along with other symptoms such as headache, blurred vision, flushing, sweating, and bradycardia. AHS occurs due to an uncontrolled reflex arc between the sensory nerves below the level of injury and the sympathetic nervous system above the level of injury. It is critical to identify and treat AHS promptly to prevent serious complications such as stroke, seizures, and even death.
