Introduction:
Hematoma blocks are effective pain management modalities for closed reduction of distal radius fractures. Complications of hematoma blocks are associated with systemic reaction to anesthetic used.
Case Report:
We present a case report of an elderly patient who received a hematoma block of lidocaine and bupivacaine for a distal radius fracture and subsequently developed a generalized tonic clonic seizure. The dose of both lidocaine and bupivacaine were well within the suggested dose limit. The episode was self limiting and patient had the cast applied.
Conclusions:
We conclude that hematoma blocks with a combination of anesthetics may decrease the threshold to neurologic complications, especially in elderly patients. Precautions and ready treatment measures should be made available while performing closed reduction.
