This patient showed complete quadriplegia (motor below C6 and sensory below C7) due to fracture of the 6th cervical vertebra. An indwelling urethral catheter had been inserted into the bladder for 3 months, diminishing bladder expansiveness. Bladder capacity decreased to 200 ml and the patient frequently experienced headaches whenever his bladder was full. To obtain smoother urine flow, a supra-pubic cystostomy was performed. The headaches were temporarily cured, but soon relapsed with extreme increases in blood pressure, representing typical symptoms of autonomic dysreflexia. However, no poten- tial triggers were identified or removed, and lack of blood pressure management led to left putaminal hemorrhage. Despite operative treatment, the right upper extremity showed progressive increases in muscle tonus and finally formed a frozen shoulder with elbow flexion contracture. Two factors contributed to this serious complication: first, autonomic dysreflexia triggered by minor malfunction and/or irritation from the cystostomy catheter; and second, the medical staff lacked sufficient experience in and knowledge about the management of autonomic dysreflexia. It is of the utmost importance for medical staff engaging in rehabilitation of spinal patients to share information regard- ing triggers of autonomic dysreflexia and to be thorough in ensuring proper medical management.

On the afternoon of Saturday, August 14, after ram- bling about by wheelchair, he developed headache with a cold sweat. At this time, his blood pressure reached 211/128 mmHg with a regular heart rate of 67 beats/min. The cystostomy catheter was inspected, but no obvious occlusion was apparent. An on-duty doctor could not make a clear diagnosis about these symptoms. To obtain quick relief from the headache, a loxoprofen sodium tablet (Loxonin) was adminis- tered, but had no effect in relieving the headache and hypertension. About an hour later, the patient began salivating from the right corner of the mouth, became inarticulate, and unable to move the right upper ex- tremity at all, and finally entered a semi-comatose state.
