Effect of Nebulized Dexmedetomidine on Post-dural Puncture Headache

Nebulized Dexmedetomidine was prepared to provide 1 µg/kg and the calculated dose of DXM was diluted by 4-ml of 0.9% saline and was provided in the nebulizer to be nebulized in twice daily; i.e. every 12 hours for 72 hours

The injection solution was prepared by mixing 2-ml of 2% lidocaine with 2-ml (8 mg) of dexamethasone. A line was drawn extending between the mastoid process and the external occipital protuberance, this line was divided as a medial third and lateral two-thirds to localize the occipital artery and the greater occipital nerve was located on the medial side of the artery where it exits out of the trapezius fascia into the nuchal line about 5-cm lateral to midline and injection was performed bilaterally to achieve bilateral block.
