title: Postdural puncture headache in patients with chronic pain.
abstract: The incidence of headache after dural puncture in patients being treated for chronic pain was studied prospectively. Dural punctures were performed in 142 patients and headache developed in 13 (9.2%). Four of 32 patients (12.5%) who underwent diagnostic differential spinal and nine of 110 patients (8.2%) given intrathecal steroid injection developed headache. There was a 10.7% incidence of headache when a 22-gauge needle was used as compared to 5% with a 25-gauge needle. This difference was not statistically significant. The incidence decreased with increasing age. The incidence of postdural puncture headache in chronic pain patients does not differ significantly from that previously reported for surgical patients. All patients who developed headache responded to treatment which consisted of intravenous and oral fluids, analgesics, bed rest, and, if necessary, epidural blood patch.
