Intrathecal Catheterization by Epidural Catheter: Management of Accidental Dural Puncture and Prophylaxis of PDPH.
Accidental or inadvertent dural puncture during epidural anaesthesia results in high incidence of post dural puncture headache (PDPH). Spinal or intrathecal catheter in such a situation, provides a conduit for administration of appropriate local anaesthetic for rapid onset of intraoperative surgical anaesthesia and postoperative pain relief. This procedure prevents PDPH if catheter left in situ for > 24 hrs and also avoids the associated risks with a repeat attempts at epidural analgesia. Primary aim of this study was to observe the effect of spinal catheter on incidence of PDPH, and to assess early and delayed complications of spinal catheterization by epidural catheter. In prospective clinical study 34 patients who had accidental dural puncture during epidural anaesthesia were included. The catheter meant for epidural use was inserted in spinal space and used for spinal anaesthesia and postoperative analgesia. Catheter was removed between 24-36hrs after surgery. The incidence of accidental dural puncture was 4%(34/846). Two patients 5.88% (2/34) had transient paresthesia during spinal catheter insertion. Post dural puncture headache occurred in 11.76% (4/34) patients. Two patients required epidural blood patch and two patients were managed with conservative treatment. No patient had any serious intraoperative or postoperative side effects. Epidural catheter can be used as spinal catheter to manage accidental dural puncture without serious complications, and it also prevents PDPH.
