[Prevalence of maternal near miss and adverse pregnancy outcomes in Zhejiang province].

OBJECTIVE

To explore the prevalence of maternal near miss (MNM) and adverse pregnancy outcomes in Zhejiang province by MNM surveillance system.

METHODS

A cross-sectional study was conducted during 2012 and 2013. All MNM cases were recruited from the MNM surveillance system. The information was reported by direct network report system, including personal information, obstetric complications, maternal rescue measures, rescue process and severe maternal and perinatal outcomes.

RESULTS

A total of 826 MNM patients were recruited. The MNM rate was 5.6 cases/1 000 live births (LB). Maternal gestational hypertension was the most common disease among MNM, accounting for 19.9% (n = 164) . The second prevalent one was insufficient uterine contraction, accounting for 19.6% (n = 162). Placenta previa was the third one accounting for 17.7% (n = 146). Among adverse pregnancy outcomes, 139 cases underwent hysterectomy (n = 139, 16.8%). There were 81 perinatal deaths with a perinatal mortality of 10.4%. And 279 cases (39.9%) were preterm.

CONCLUSION

MNM surveillance system is valuable for grasping the prevalence of MNM. And it helps to reduce MNM rate by improving the quality of obstetrics and lower the preterm rate and perinatal mortality.
