[Analysis of clinical early warning informations of severe preeclampsia before onset].

Objective

To explore the early warning informations of severepre-eclampsia before onset.

Methods

The study was an observational case-control study. The study group consisted of 77 single-pregnancy preeclampsia pregnant women and the control group took 154 normal cases who were delivered to Tianjin Fifth Central Hospital (Peking University binhai Hospital) from January 2014 to December 2017 in the perinatal care referral system in Tianjin. To analyze changes in clinical indicators before the onset of severe pre-eclampsia with statistical methods.

Results

Prehypertension, weight gain>0.85 kg/week, fetal growth restriction, edema and decline of plasma albumin, thrombocytopenia, poor compliance, perinatal examinations and examinations in tertiary hospitals were associated with severe pre-eclampsia (P<0.001). Multivariate regression analysis showed that the risk factors of severe preeclampsia were pre-hypertension, weight gain>0.85 kg/week, edema, thrombocytopeniaand poor compliance. The increase in the number of prenatal examinations in tertiary hospitals was a protective factor for severe preeclampsia.

Conclusion

Prehypertension, weight gain during pregnancy (>0.85 kg/week), edema, thrombocytopenia, and poor compliance were warning informations of severe pre-eclampsia, and the increased number of prenatal examinations in tertiary hospitals was a protective factor for severe pre-eclampsia.
