Outcome Measures
Primary Outcomes (1)
Incidence of postdural puncture headache
within the first 14 days of epidural placement
Secondary Outcomes (12)
PDPH characteristics (quality, distribution, postural versus non-postural nature, associated symptoms)
within first 14 days post-epidural placement, and if necessary, up to 1 year post-epidural placement
Severity of pain related to PDPH
within first 14 days post-epidural placement, and if necessary, up to 1 year post-epidural placement
Degree of dysfunction and disability related to PDPH symptoms
within first 14 days post-epidural placement, and if necessary, up to 1 year post-epidural placement
Duration of PDPH-related symptoms
within first 14 days post-epidural placement, and if necessary, up to 1 year post-epidural placement
Pain and pain relief (first and second stage labor analgesia following epidural placement and overall pain relief) as rated by the patient, compared between groups
within 24 hours of epidural placement
- +7 more secondary outcomes

ACTIVE COMPARATORtraditional =\>18g needle
Interventions
Patients in the experimental group will receive a 23g 90cm adult length epidural catheter placed via a 19g Tuohy epidural needle (SIMS Portex, Hythe, UK). The 19g Tuohy needle is a standard 3½ inch length.
Patients in the control arm will receive a traditional large gauge (16g, 17g or 18g Tuohy or Hustead) epidural needle and a traditional epidural catheter. Two control needles and two control catheters will be designated apriori by each institution for use in the study.
