Summary
Prenatal interventions significantly reduce shoulder dystocia in gestational diabetes mellitus patients. Intensive management, including diet and insulin, is more effective than diet alone for preventing this birth complication.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
- Perinatal Research
Background:
- Shoulder dystocia is a significant obstetric emergency with potential for severe neonatal and maternal morbidity.
- Effective prevention strategies are crucial for improving birth outcomes, particularly in high-risk pregnancies.
Purpose of the Study:
- To evaluate the efficacy of composite prevention strategies for shoulder dystocia.
- To synthesize evidence from randomized controlled trials (RCTs) on interventions aimed at reducing shoulder dystocia incidence.
Main Methods:
- A systematic literature search was conducted across major databases (PubMed, EMBASE, EBSCO, Cochrane Library) for RCTs on shoulder dystocia prevention.
- Included studies were screened, quality assessed, and data analyzed using meta-analysis with RevMan 5.1 software.
Main Results:
- Prenatal intervention significantly reduced shoulder dystocia in gestational diabetes mellitus (GDM) patients (OR=0.40).
- Intensive prenatal intervention (diet and insulin) was more effective than less intensive (diet only) management (OR=0.29).
- Early induction of labor showed marginal benefit for GDM patients with suspected macrosomia (OR=0.34) and GDM patients at 38-39 weeks gestation (OR=0.18).
Conclusions:
- Targeted interventions for high-risk pregnancies can effectively decrease the occurrence of shoulder dystocia.
- Management strategies for GDM and suspected macrosomia warrant further investigation to optimize prevention.
