After accidental dural puncture (ADP) with large bore epidural needles, postdural puncture headache (PDPH) develops in 16%–86% of patients, which is unpleasant and interferes with activities of daily life of the patient. Hence we aimed to assess the effect of intrathecal catheter insertion after ADP with 18G Tuohy needle on incidence of PDPH.
In all, 173 patients after ADP were enrolled and divided into two groups according to the choice of treating anesthesiologist. Group IC included 74 patients who had intrathecal catheter placed in subarachnoid space. In group NIC, which included 99 patients, one of the following was done: epidural catheter was cited in a different intervertebral space, or the procedure was abandoned and general anesthesia was administered or single-shot spinal anesthesia was administered through the Tuohy needle itself. The catheters were left in situ for 36–48 h. Patients were monitored for the next 7 days after ADP for the incidence of PDPH, its severity and requirement of analgesics, and duration of catheter in situ from the time of ADP.
