Informatized WHO Checklist with Standardized Oxytocin Slashes Post-Cesarean Hemorrhage by 60% and Improves Maternal Outcomes

Postpartum hemorrhage (PPH) remains a leading cause of maternal mortality and morbidity globally, particularly following cesarean section. Current standard-of-care protocols often lack the comprehensive, real-time integration needed to consistently prevent PPH, leading to variability in outcomes. This study addresses the critical gap in standardized, evidence-based interventions by evaluating an informatized system that combines a robust checklist with optimized oxytocin administration, aiming to enhance uterine contraction and reduce blood loss effectively.

Researchers conducted a retrospective study involving 100 women undergoing cesarean section, divided into a control group (routine care) and an intervention group (50 cases each). The intervention group received an informatized system based on the WHO "Safe Childbirth Checklist" combined with an optimized oxytocin strategy. Primary endpoints included blood loss at 2 hours and 24 hours, PPH incidence, hemoglobin reduction, additional uterotonic use, and hospital stay. Pelvic floor function and quality of life were also assessed. Multivariate logistic regression identified factors associated with PPH.

Compared to the control group, the intervention group demonstrated significantly lower blood loss at 2 hours (312.48 ± 70.21 mL vs 420.56 ± 85.34 mL) and 24 hours (415.76 ± 95.63 mL vs 540.12 ± 110.45 mL), with all P < .05.

The incidence of PPH was dramatically reduced in the intervention group, falling from 30.0% in the control group to just 12.0% (all P < .05). Hemoglobin reduction, additional uterotonic use, and hospital stay were also significantly decreased (all P < .05). Pelvic floor function improved, evidenced by higher vaginal dynamic pressure and muscle tone scores (P < .05). Process quality indicators, including checklist completion, timely oxytocin administration, and blood loss measurement accuracy, improved significantly, alongside shorter emergency response times and higher staff satisfaction (all P < .05). The intervention was identified as an independent protective factor for PPH, with an odds ratio = 0.157 (P < .05).
