Objective To explore the effect of perioperative management on the outcome of dangerous placenta previa. Methods A total of 95 patients of dangerous placenta previa in our hospital were selected as the research object randomly, the selected patients were randomly divided into observation group and control group, the control group were treated by routine management, and the observation group were treated by perioperative management, analyze the difference of operation indexes, complications and the pregnancy outcomes of the two groups. Results The operation time, intraoperative blood loss of the observation group of patients were significantly better than that of control group (P<0.05), the postoperative complications of observation group (22.92%) was significantly lower than the control group (59.57%), the neonatal Apgar score of the observation group was better than control group with statistical significance (P<0.05). Conclusion Perioperative management has a high application value in the treatment of patients with dangerous placenta previa, and can significantly improve the operation index, improve the level of neonatal health, help to improve the pregnancy outcomes, and It is worthy of clinical application.
