Post-Dural Puncture Headache (PDPH) -
Part 2 (Blood Patch)
If conservative measures are ineffective in ameliorating PDPH, another intervention is the epidural blood patch - in practice since last 50 years with success. The epidural blood patch consists of injecting 5-20 mLs of autologous blood into the epidural space, in the region of the suspected dural 'hole.' Once the epidural space is located, autologous blood is drawn from an intravenous (IV) line, and then injected as a bolus into the epidural space. In 90% of cases, the response is positive and immediate. And, long-term relief of PDPH occurs in the almost all cases.
