Key result
Low-concentration neuraxial analgesia compared with nonneuraxial analgesia showed no significant difference in the incidence of instrumental vaginal delivery (RR 1.52; 95% CI 0.97-2.40).
Why the study?
Does maintenance of epidural analgesia with low-concentration local anesthesia increase the incidence of instrumental vaginal delivery or prolong the second stage of labor in laboring women?
Population
Laboring women (discussing a meta-analysis of 8 trials with approximately 1500 participants)
Comparison
Maintenance of epidural analgesia with… vs Nonneuraxial analgesia

This editorial emphasizes that current evidence comparing low-concentration neuraxial analgesia to nonneuraxial analgesia is underpowered and heterogeneous, supporting the continued need for individualized, titratable labor analgesia.

Cynthia A. Wong (2017) conducted an editorial in Labor. Neuraxial labor analgesia vs. Nonneuraxial analgesia was evaluated on Incidence of instrumental vaginal delivery (RR 1.52, 95% CI 0.97-2.40). Low-concentration neuraxial analgesia compared with nonneuraxial analgesia showed no significant difference in the incidence of instrumental vaginal delivery (RR 1.52; 95% CI 0.97-2.40).
