Intrathecal Catheter Placement Versus Resiting Epidural Catheter After Dural Puncture in Obstetric Patients

Epidural anesthesia represents the most popular method for pain relief during labour. Unintentional dural puncture (UDP) occurs in 0.4-1.5% of labour epidural analgesia, representing therefore the most common complication. Up to 80% of patients with a UDP may develop a post-dural puncture headache (PDPH). When a UDP occurs, two possible strategies have been proposed in order to ensure analgesia during labour: either resiting the epidural catheter in a different intervertebral space, or inserting an intrathecal catheter. Both strategies proved to equally provide analgesia during labour, but their relative contribution in preventing PDPH is still not known. The primary aim of this multicenter randomized controlled trial is therefore to compare these two strategies in the occurrence of PDPH at 24 hours from the UDP.
