Study summary

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% .

Read the detailed description

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.

Glass particle contamination is known to occur on opening single-dose drug ampoules. Although supporting data are lacking, intrathecal drug administration during subarachnoid blocks and chemotherapy with glass particle contamination is potentially hazardous,

Study arms

  • Placebo comparator
    Group T0

    Parturients will receive spinal anesthesia for elective cesarean delivery with injection of 25 μg fentanyl plus 12.5 mg of hyperbaric bupivacaine 0.5% (2.5 mL) immediately after opening the bupivacaine ampule and directly after immediate aspiration with an unfiltered 3 ml syringe

    Drug: Hyperbaric bupivacaine 0.5% (2.5 mL) aspirated immediately after opening the bupivacaine ampule

  • Active comparator
    Group T5

    Parturients will receive spinal anesthesia for elective cesarean delivery with injection of 25 μg fentanyl plus 12.5 mg of hyperbaric bupivacaine 0.5% (2.5 mL) directly after 5 min' delayed aspiration from opening of the bupivacaine ampule with an unfiltered 3 ml syringe to allow glass particles to settle onto the bottom of the ampule

    Drug: Hyperbaric bupivacaine 0.5% (2.5 mL) aspirated 5 minutes delayed after opening the bupivacaine ampule

What researchers measure

Primary outcomes

  1. The incidence of post-dural puncture headache (PDPH)

    Assessed using the visual analog score of pain which ranges from 0-10, where 0 = no pain and 10 = maximum worst pain

    Time frame: The first 120 hours during the post-partum period.
