Abstract

Background and methods. There is a growing awareness of the possibility of headache resulting from intracranial air secondary to identification of the epidural space by loss of resistance using air (LOR-A). Most reported cases have been attributed to subarachnoid air passage. A case is described of sudden headache following LOR-A.

Results. Various features of the case suggest that the passage of air to the head was subdural rather than subarachnoid.

Conclusions. Recovery was uneventful.

  • Complications
  • epidural anesthesia
  • headache
  • subdural space.
