However, standard epidurals can have failure rates and may be difficult to reliably confirm correct placement.\n\nThe dural puncture epidural (DPE) technique has been introduced to improve confirmation of epidural placement and potentially enhance analgesia. It involves identifying the epidural space, puncturing the dura with a spinal needle without injecting medication, confirming cerebrospinal fluid flow, and then placing the epidural catheter. While DPE may improve analgesia and drug spread, current evidence is limited and does not clearly demonstrate superiority over standard epidural techniques.\n\nAt The Ohio State Wexner Medical Center, DPE is used routinely for labor epidurals. This observational study evaluates epidural failure rates and anesthesia provider confidence in performing DPE, while also collecting procedural details, patient characteristics, analgesic outcomes, and complications. Provider confidence is assessed using a 3-point scale along with factors influencing performance, and patient outcomes include pain relief, need for rescue dosing, and overall epidural effectiveness.","This is a single-center, prospective observational study conducted at The Ohio State University Wexner Medical Center to evaluate the effectiveness and safety of the dural puncture epidural (DPE) technique for labor analgesia.\n\nNeuraxial analgesia is the gold standard for pain relief during labor, with conventional epidural (CE) and combined spinal-epidural (CSE) being the most commonly used techniques. The DPE technique is a modification of the CSE approach in which the dura is intentionally punctured with a spinal needle to confirm correct epidural needle placement through visualization of cerebrospinal fluid (CSF), but no medication is injected into the intrathecal space. This approach is thought to improve epidural placement accuracy, enhance analgesia, and reduce epidural failure while maintaining the safety profile of a conventional epidural. Although DPE has gained widespread clinical use, current evidence regarding its superiority over conventional epidural techniques remains limited and inconsistent.\n\nThe primary objective of the study is to determine the success rate of the DPE technique, defined by successful visualization of CSF following dural puncture. Secondary objectives include evaluating epidural success following successful and unsuccessful DPE, anesthesia provider confidence before and after the procedure, labor analgesia effectiveness, maternal satisfaction with pain management, need for rescue analgesia, delivery outcomes, neonatal outcomes (Apgar scores and NICU admission), and procedure-related complications.\n\nThe study will enroll approximately 150 term pregnant patients requesting labor epidural analgesia and anesthesia care providers with prior epidural experience. Since DPE is already the institutional standard of care, participation in the study does not alter patient management. Instead, data are collected prospectively from routine clinical care, while participating anesthesia providers complete brief surveys assessing their confidence, procedural details, and technical success.\n\nClinical data collected include maternal demographics, obstetric characteristics, labor analgesia outcomes, epidural performance measures, rescue analgesia requirements, delivery mode, neonatal outcomes, and complications such as post-dural puncture headache, unilateral block, accidental dural puncture, catheter-related issues, or persistent neurologic symptoms. Epidural success is defined by adequate pain relief (pain score ≤3) and appropriate bilateral sensory blockade within 20 minutes after the loading dose.\n\nDescriptive statistics will summarize patient and procedural characteristics, while comparative analyses will evaluate differences in outcomes between successful and unsuccessful DPE procedures. Overall, this study aims to better characterize the clinical performance of the DPE technique, determine its impact on epidural success and patient outcomes, and assess anesthesia provider confidence in performing the procedure under routine clinical practice.",[18],"Labor Pain",[],"OBSERVATIONAL",[],{"count":23,"type":24},150,"ESTIMATED",[26],{"type":27,"name":28,"description":29,"armGroupLabels":30},"PROCEDURE","Dural Puncture Epidural (DPE) Technique","All eligible anesthesia care providers and laboring patients receiving the dural puncture epidural (DPE) technique as part of routine clinical care at The Ohio State Wexner Medical Center.
