    Abstract:
    Postdural puncture headache (PDPH) is one of the most common complications of spinal anesthesia, where adequate hydration with bed rest in the horizontal position is the initial recommendation. Epidural blood patch is to date the most effective treatment, but it is an invasive procedure that may result in serious complications. The aim of the current study was to conduct a prospective, randomized, single-blinded comparison between bilateral occipital blockade and conventional expectant therapy in adults suffering from PDPH. A primary hypothesis was that occipital blockade would result in better pain management and quicker return to normal activity. Fifty adult patients diagnosed with PDPH were randomly divided into two equal groups of 25 each. All patients in the block group received greater and lesser occipital nerve blocks, whereas the control group received adequate hydration, complete bed rest, and analgesics. Forty-seven patients entered into the final analysis as three patients withdrew from study. Complete pain relief was achieved in 68.4% of block patients after 1 to 2 blocks, with 31.6% ultimately receiving up to 4 blocks. Visual analog scales were significantly lower in the block group (P < 0.01), and the block group consumed significantly less analgesics in the follow-up period (P < 0.05) compared with control group. Block patients had significantly shorter hospital stays and sick leave periods (P < 0.001). The studied method is superior to expectant conservative therapy in the treatment of patients suffering from PDPH.
