Spinal Analgesia and Labor Outcomes in Low-Risk Parturients, 800 Patients

A retrospective cohort study of 800 low-risk parturients from June 2024 to February 2026, assessing the association of a spinal analgesia-based management strategy with labor progression and maternal/neonatal outcomes. The dataset includes 610 patients in a non-SA group and 190 in an SA group, with primary outcomes of prolonged second-stage labor, emergency cesarean delivery, and umbilical arterial pH. The study was conducted by Shunsuke Maruyama and published on figshare.

Use Cases

• Modeling the risk of prolonged second-stage labor based on analgesia management strategy.
• Analyzing the association between spinal analgesia and the frequency of vacuum-assisted delivery.
• Investigating the relationship between a bundled management framework and emergency cesarean delivery rates.
• Assessing neonatal outcomes, such as low umbilical arterial pH, in the context of different intrapartum pain management approaches.

Strengths

• Includes data from 800 patients, with 610 in a non-SA group and 190 in an SA group.
• Reports specific statistical findings, such as an adjusted odds ratio (aOR) of 0.314 for reduced risk and an absolute risk reduction of 8.6%.
• Covers a defined time range from June 2024 to February 2026.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The study is described as single-center, which may limit generalizability.
