Application effect of modified early warning scoring combined with rapid response system on patients with severe preeclampsia
Objective To explore the application effect of modified obstetric early warning scoring(MEWS)combined with rapid response system(RRS)in patients with severe preeclampsia(SPE).Methods Clinical data of 252 patients with SPE admitted to Department of Obstetrics,Nanjing First Hospital from May 2019 to June 2021 were collected.One hundred and twenty-six patients with SPE underwent emergency RRS intervention from May 2019 to June 2020 were selected as control group,and 126 patients with SPE underwent emergency MEWS combined with RRS inter-vention from July 2020 to June 2021 were selected as intervention group.Treatment time,gestational age at termination,delivery mode,hospitaliza-tion time,incidence of complications,and perinatal outcome between two groups were compared.Results Treatment time and hospitalization time in intervention group were shorter than those in control group,gestational age at termination and percentage of natural delivery in intervention group were higher than those in control group(P＜0.05).The incidence of HELLP syndrome,placental abruption,liver and kidney injury and postpartum hemorrhage in intervention group were lower than those in control group(P＜0.05).There was no significant difference in the incidence of venous thromboembolism between two groups(P＞0.05).The incidence of premature delivery,fetal distress,neonatal asphyxia,and low birth weight in in-tervention group were lower than those in control group(P＜0.05).There was no significant difference in the mortality rate of perinatal infants be-tween two groups(P＞0.05).Conclusion MEWS combined with RRS can improve the speed of treatment for SPE patients,reduce hospitalization time,reduce the incidence of complications,and improve pregnancy and perinatal outcomes.The clinical application effect is relatively good.
