Role of lumbar puncture level on the onset of epidural labor analgesia: a randomized controlled trial

Puncturing through the L2-3 interspace is associated with faster pain relief and a better experience for parturients. These findings present a superior option for anesthesiologists when conducting epidural labor analgesia. Key messages What is already known on this topic? Epidural analgesia is an effective way to relieve labor pain. What this study adds? Puncturing via lumbar 2-3 interspace induces more rapid onset of epidural analgesia. How this study might affect research, practice or policy? Lumbar 2-3 interspace is a superior option in terms of the speed of pain relief and satisfaction of parturients when conducting epidural labor analgesia.
