[Cardiac arrest in a 10-month-old boy with spinal cord injury]

A 10-month-old boy with a previous upper spinal cord injury was admitted to hospital with acute respiratory and circulatory distress. Shortly after admission the boy had severe bradycardia leading to asystolia and pulseless electrical activity. He was successfully resuscitated, and the investigation that followed excluded infection, congenital heart defect, arrhythmia and cerebral haemorrhage. Over the following days the patient had several episodes of isolated bradycardia and combined bradycardia and hypotension. It was concluded that the patient suffered from autonomic dysreflexia, triggered by a distended urinary bladder. He was treated with intermittent catheterization and a permanent pacemaker, and after 12 months there have not been any symptomatic episodes or registered arrhythmias. Autonomic dysreflexia is a common and well known complication of spinal cord injury above Th6, but the literature on paediatric patients is scarce. Our case report presents an infant with an atypical and severe episode of autonomic dysreflexia. Patients with spinal cord injury, their caregivers and health-care personal should be aware of this complication of spinal cord injury, in order to prevent and treat autonomic dysreflexia properly and avoid potentially fatal episodes.
