Prevention strategy for post dural puncture headache.

We report the anesthetic management of a parturient after an unintentional dural puncture while performing epidural anaesthesia for caesarean section and the strategy to prevent postdural puncture headache (PDPH). We injected the cerebrospinal fluid (CSF) back into the subarachnoid space and then administered intrathecal 1.5 mL 0.5% hyperbaric bupivacaine and fentanyl 20 microg to maintain CSF volume via epidural needle. The epidural catheter was inserted following re-identification of the epidural space for possible epidural top-up requirement and postoperative pain relief. After adding 3 mL of 0.5% isobaric bupivacaine via epidural catheter, sensory block level reached at T4 bilaterally. No PDPH was observed.
