Blood pressure cuff compression injury of the radial nerve.
We describe a 19-year-old man who underwent emergency laparotomy for perforated peptic ulcer. He was otherwise healthy before this admission with no history of diabetes mellitus or neuropathy. A standard-size adult blood pressure cuff connected to a Dinamap monitor, set to cycle automatically every 3 minutes was affixed to his left upper extremity during surgery. One day after the operation he complained of numbness over the dorsum of the left hand and wrist drop. Physical examination revealed 0/5 muscle power of the left wrist and finger extensor muscles with reduced sensation on the radial aspect of the dorsum of the same hand. A diagnosis of acute radial nerve injury was made and rehabilitation was started. The wrist numbness and sensation improved with physical therapy, and he was discharged 9 days after the operation with an active wrist splint. He continued with rehabilitation on an out-patient basis. The muscle power of the wrist extensors gradually improved after three months of physical therapy and reverted to completely normal one month later. Locating the cuff higher on the arm, away from the elbow joint, to avoid the most superficial portion of radial nerve, may prevent this type of compression injury especially in asthenic patients.
