先兆子痫的病因还不清楚,多年来认为是由高血压、浮肿、蛋白尿构成的综合征。当前英国诊断先兆子痫广泛采用 Nelson 标准,该标准不包括浮肿,蛋白尿仅用于区别轻型或重型,标准规定舒张压达到90mmHg 即可诊断先兆子痫,但对血压增值未作规定。为探寻诊断先兆子痫的最好标准,作者对牛津产科资科系统中1981—1984年的16,211名单胎孕妇进行的分析。以了解血压增值是否有助于诊断先兆子痫,每例包括首次血压、围产期最高血压、舒张压增值、分娩时孕龄。因收缩压无恒定值,此前研究也无详细报道,故未作为一项指标。分析结果全部
The etiology of preeclampsia is unclear and has been considered for many years as a syndrome of hypertension, edema and proteinuria. Currently, the Nelson standard is widely used in the diagnosis of preeclampsia in the UK. The standard does not include edema. Proteinuria is only used for distinguishing between light and heavy types. The standard stipulates that diastolic blood pressure reaches 90mmHg to diagnose preeclampsia, but no stipulation on blood pressure increase. To explore the best criteria for diagnosis of preeclampsia, the authors analyzed 16,211 singleton pregnant women from 1981 to 1984 in the Oxford Obstetrics and Gynecology Systems. In order to understand whether the increase in blood pressure is helpful in the diagnosis of preeclampsia. Each case includes the first blood pressure, the highest blood pressure during perinatal period, the increase in diastolic blood pressure, and the gestational age at labor. No constant value due to systolic blood pressure, no previous study reported in detail, it is not as an indicator. Analysis of the results of all
