Main Article Content
The management of position during labor directly influences the maternal experience and obstetric outcomes. Objective: To compare the incidence of maternal and neonatal adverse outcomes between women who delivered in vertical versus horizontal birthing positions at the National Maternal Perinatal Institute. Methods: Analytical, observational, retrospective cohort study. A total of 304 women with singleton, term, vaginal deliveries between September and November 2022 were included, categorized into vertical (n=130) and horizontal (n=174) birth groups. Bivariate analyses and multivariate logistic regression were used to compare outcomes. Results: Women in the vertical birth group had a significantly lower rate of severe perineal tears (1,5% vs. 5,2%, p=0,041) and shorter duration of the second stage of labor (45,2 vs. 58,9 minutes, p<0,001). After adjustment, vertical position remained an independent protective factor against severe tears (Adjusted OR 0,28; 95% CI 0,09-0,89). No significant differences were observed in postpartum hemorrhage or neonatal adverse outcomes. Conclusion: In our cohort, vertical position was associated with more favorable maternal perineal outcomes, supporting its promotion as a safe option in clinical practice.
El manejo de la posición durante el parto influye directamente en la experiencia materna y en los resultados obstétricos. Objetivo: Comparar la incidencia de resultados adversos maternos y neonatales entre las mujeres que tuvieron un parto en posición vertical versus horizontal en el Instituto Nacional Materno Perinatal. Métodos: Estudio analítico, observacional, retrospectivo de cohortes. Se incluyeron 304 mujeres con partos vaginales a término entre septiembre y noviembre de 2022, categorizadas en grupos de parto vertical (n=130) y horizontal (n=174). Se utilizaron análisis bivariados y regresión logística multivariada para comparar resultados. Resultados: Las mujeres en el grupo de parto vertical tuvieron una tasa significativamente menor de desgarros perineales severos (1,5% vs. 5,2%, p=0,041) y una duración menor del segundo estadio del parto (45,2 vs. 58,9 minutos, p<0,001). Tras el ajuste, la posición vertical se mantuvo como factor protector independiente contra desgarros severos (OR ajustado 0,28; IC 95% 0,09-0,89). No se observaron diferencias significativas en hemorragia postparto o resultados neonatales adversos. Conclusión: En nuestra cohorte, la posición vertical se asoció con resultados perineales maternos más favorables, respaldando su promoción como opción segura en la práctica clínica.
