The application value of the third-pregnancy comprehensive intervention led by midwives was analyzed.Results: the natural delivery rate was higher than the control group (P <0.05);lower (P <0.05);Lower self-efficacy and social support scores in the control group (P <0.05): lower GAD-7 and PHQ-9 (P <0.05);lower GQOL-74 scores than the control group (P <0.05). Conclusion: the comprehensive nursing intervention in the field, improve the cognition of natural delivery, improve the natural delivery rate, promote the effective improvement of maternal self-efficacy and social support evaluation, reduce the influence of postpartum bad mood, optimize the overall quality of life, has high clinical application value.展开更多
