Post-dural puncture headache (PDPH) is a potential and debilitating complication of spinal anesthesia in pregnant patients undergoing caesarean sections (CS), with a reported incidence of 0.5%-2% .

Various methods for the management of PDPH are present including proper hydration, maintaining a supine posture, caffeine, paracetamol, nonsteroid anti-inflammatory drugs (NSAID), theophylline, opioids like morphine and fentanyl, with the only clearly effective treatment being the epidural blood patch.
