The total deliveries in Shanghai from 1981 to 1990 were 1,770,103 and there were 456 cases of maternal death. Among them, 42 cases were caused by pregnancy induced hypertension (PIH) which accounted for 9.21% and ranked fourth in the causes of maternal death in Shanghai. The maternal mortality of PIH was 2. 37/10(5). The cerebrovascular accident and heart failure were the leading causes which accounted for 66.67%. The study showed that strengthening prenatal care, supervising 3 main symptoms and signs of PIH, paying attention to mean arterial pressure (MAP), using antispasm drugs such as MgSO4 in proper way and timely termination of pregnancy are the key points of decreasing maternal death of PIH. The average MAP of 18 cases died of cerebrovascular accident was 17 kPa (1kPa = 7.5 mmHg). Among them, MAP > or = 18.7 kPa (140 mmHg) was found only in 4 cases which accounted for 22.22%. It suggested that the threshold value of cerebrovascular accident at the level of MAP > or = 18.7 kPa may be too high and need to be further studied.
1981年至1990年上海的分娩总数为1,770,103例，孕产妇死亡456例。其中，42例由妊娠高血压综合征（PIH）引起，占上海孕产妇死亡原因的9.21%，位居第四。PIH的孕产妇死亡率为2.37/10万。脑血管意外和心力衰竭是主要死因，占66.67%。研究表明，加强孕期保健，监测PIH的三大主要症状和体征，关注平均动脉压（MAP），合理使用硫酸镁等解痉药物并及时终止妊娠是降低PIH孕产妇死亡的关键。18例死于脑血管意外者的平均MAP为17kPa（1kPa = 7.5mmHg）。其中，MAP≥18.7kPa（140mmHg）的仅4例，占22.22%。这表明MAP≥18.7kPa水平的脑血管意外阈值可能过高，有待进一步研究。
