title: Postdural puncture headache: the role of prophylactic epidural blood patch.
abstract: Prophylactic epidural blood patch may prevent postdural puncture headache that develops after intentional or inadvertent dural puncture. However, despite earlier reports that this procedure was of value, subsequent studies have failed to show it has significant advantages over delayed blood patch. Reports that were supportive of this technique were based on nonrandomized observational studies with significant selective bias. At the present time, most centers do not routinely offer prophylactic blood patches, and those that do report a variable success rate. A recent case study of permanent neurologic deficit after prophylactic epidural blood patch has also raised some concern about the safety of this prophylactic technique.
