目的 旨在了解宁夏回族自治区危重孕产妇妊娠合并症/并发症的发生情况，为降低该地区孕产妇死亡率、提高产科危重症救治能力提供依据。方法 回顾性分析2020年宁夏回族自治区13家危重孕产妇监测医院上报的《孕产妇个案调查表》中危重孕产妇的孕期保健、妊娠合并症/并发症、危重症和分娩等相关情况。结果 2020年宁夏回族自治区13家危重孕产妇监测医院共监测孕产妇24 087例，孕产妇合并症/并发症发生前5位的是贫血(286.84‰)、妊娠期高血压(73.53‰)、妊娠期糖尿病(46.42‰)、宫缩乏力(40.15‰)及胎盘早剥(7.43‰)。其中贫血、妊娠期高血压、宫缩乏力的发生率农村高于城市，妊娠期糖尿病和胎盘早剥的发生率城市高于农村。结论 应加强孕产期保健，提高产科医师对孕产妇合并症/并发症及其高危因素的识别能力，加强基层医疗保健机构对产妇的救治能力，开展健康宣教，建立科学合理的饮食理念，从而进一步降低孕产妇死亡率。

Objective To investigate the incidence of pregnancy complications among maternal near miss in Ningxia Hui Autonomous Region, in order to provide evidence for reducing maternal mortality ratio(MMR) and improve health professionals' ability to rescue critically ill pregnant women. Methods The situation of perinatal health care, pregnancy complications, critical illness and delivery reported by maternal case report form from 13 surveillance hospitals in Ningxia Hui Autonomous Region, 2020 were analyzed retrospectively. Results A total of 24 087 pregnant women were involved. The top 5 pregnancy complications were anemia(286.84‰), gestational hypertension(73.53‰), gestational diabetes(46.42‰), uterine inertia(40.15‰) and placental abruption(7.43‰),respectively. The incidence of anemia, gestational hypertension and uterine inertia in rural areas was higher than that in urban areas, while the incidence of gestational diabetes and placental abruption in urban areas was higher than that in rural areas. Conclusion Maternal mortality can be further decreased by strengthening maternal health care, improving obstetricians' ability to identify pregnancy complications and high-risk factors, strengthening the ability of primary care institutions to rescue parturients, carrying out health education, and establishing scientific and reasonable diet concepts.
