Brief Summary
The primary objective of our study is to use a biased coin up-down allocation methodology to estimate the dose of bupivacaine required after the lidocaine test dose to achieve initial effective comfort in 90% of patients (post test-dose ED90) via the epidural (DPE or EPL) technique in women undergoing labor induction or augmentation; the investigators hypothesize that the investigators will be able to determine the post test-dose ED90 of bupivacaine for each technique with adequate precision to inform the optimal doses to study in a subsequent randomized trial comparing the analgesic effects of DPE vs. EPL. The investigators also hypothesize that the post test-dose ED90 of bupivacaine is lower with a DPE technique than with a conventional epidural technique.

Outcome Measures
Primary Outcomes (1)
NRS <3 at 30 min
Adequate analgesia is defined as NRS score less than 3 at 30 minutes after time 0.
30 minutes after time 0.
Study Arms (2)
DPE Group
ACTIVE COMPARATORSubjects will receive an epidural catheter via a dural puncture epidural technique.
EPL Group
ACTIVE COMPARATORSubjects will receive an epidural catheter via a traditional epidural technique.
Interventions
Each subject will receive allocated dose of bupivacaine
Eligibility Criteria
You may qualify if:
- Parturient with no major co-morbidities
- Singleton, vertex gestation at term (37-42 weeks)
- Less than or equal to 5 cm dilation
- Desire to receive epidural labor analgesia
- Numerical Rating Scale greater than or equal to 5 (NRS 0-10, where 0 = no pain, and 10 = worst pain imaginable), at time of epidural labor analgesia request.
You may not qualify if:
- Current or historical evidence of clinically significant disease or condition, including diseases of pregnancy (i.e., preeclampsia, gestational diabetes)
- Any contraindication to the administration of an epidural technique (e.g., thrombocytopenia, antiplatelet meds).
- History of hypersensitivity or idiosyncratic reaction to an amide local anesthetic agent
- Evidence of anticipated fetal complications (i.e., fetal anomalies, IUGR (Intrauterine Growth Restriction), oligohydramnios, polyhydramnios)
