Effect of butorphanol nasal spray administration on patient cooperativity during labor epidural placement: a single-center randomized controlled trial.
Article in Perioperative medicine (London, England), 2025. 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
backgroundEpidural block stands as the prevailing, secure, and efficient approach to labor analgesia. Inadequate maternal cooperation not only hampers anesthesia effectiveness but also may lead to severe consequences, including nerve damage due to positional changes.
methodsA randomized controlled clinical trial with 200 participants was conducted to compare painless delivery with epidural alone versus a combination of butorphanol nasal spray preceding epidural administration for painless delivery. The objective was to assess the combined approach's efficacy in diminishing maternal pain and enhancing maternal compliance.
resultsWithin 8-min post-anesthesia, the combined analgesic group (EXP group) exhibited significantly lower maternal pain intensity scores, improved maternal cooperation, reduced visual analogue scale (VAS) pain, and McGill scores compared to the epidural alone group (CTRL group). No statistically significant differences emerged in 24-h postpartum blood loss, labor duration, or lactation period. Neonatal indicators, including umbilical artery blood PCO2, base excess of extracellular fluid (BE-ecf), weight, and Apgar score, showed no significant differences between the EXP and CTRL groups. However, the EXP group demonstrated a higher umbilical artery blood pH than the CTRL group. The EXP group exhibited significantly higher probabilities of pain intensity scores ≤ 6, maternal cooperation scores ≤ 3, VAS scores ≤ 3 at 6-, 8-, and 10-min post-anesthesia, and McGill scores of 0 compared to the CTRL group.
conclusionButorphanol nasal spray emerges as an effective means to alleviate pain during epidural puncture in labor analgesia, markedly improving maternal anesthesia adherence. This combined analgesic method proves to be a safe and efficacious approach for maternal pain relief during labor.
