Factors associated with successful initiation of labor analgesia using the dural puncture epidural technique: a retrospective cohort study.
Article in Journal of anesthesia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe dural puncture epidural (DPE) technique has been proposed as a modification of conventional epidural analgesia that may influence onset and block quality. However, factors associated with successful initiation of labor analgesia using the DPE technique remain unclear. We aimed to identify predictors for successful initiation of labor analgesia using the DPE technique.
methodsThis retrospective study included parturients who received DPE for initiation of labor analgesia between April 2022 and March 2025. Success was defined as a composite outcome of epidural catheter placement within 15 min from initial skin puncture with the epidural needle and a numerical rating scale (NRS) pain score ≤ 3 recorded between 30 and 60 min after the first epidural bolus. Multivariable logistic regression was performed to identify independent predictors of success.
resultsAmong the 1037 parturients included in the analysis, success was achieved in 693 cases, whereas 344 were classified as failures. In the multivariable analysis, operator experience (per 10 procedures) (odds ratio 1.10, 95% confidence interval 1.04 to 1.15, P < 0.001), baseline NRS (P < 0.001), cervical dilation at initiation (P = 0.038), maternal age (P = 0.013), and spinal disorder (P = 0.034) were identified as independent predictors of success.
conclusionOperator experience was independently associated with successful initiation of labor analgesia using the DPE technique and was the only factor associated with both procedural success and early analgesic effectiveness. Operator- and patient-related factors should be considered when predicting the likelihood of successful initiation of labor analgesia using the DPE technique.
