Abstract
Objective To study the characteristics of blood flow changes of preeclampsia under ultrasound monitoring and its relationship with the prognosis of perinatal infants.Methods From January 2010 to January 2014 100 cases of pregnant women with preeclampsia in Lishui Central Hospital were selected, and they were divided into two groups according to severity of disease: mild preeclampsia group ( group A) and severe preeclampsia group ( group B) with 50 cases in each group.These patients were also divided into four groups, normal group (T1 group), normal discharge high resistance group (T2 group), low discharge high resistance group (T3 group), high discharge low resistance group ( T4 group) , according to hemodynamic classification criteria with 25 cases in each group.Another 50 cases of pregnant women admitted in the same period in the hospital were selected as the control group.Pregnancy-induced hypertension monitoring system ( Mp) was used for testing.Results The mean arterial pressure and peripheral resistance of group A were significantly higher than the control group (t value was 4.303 and 2.571, respectively, both P<0.05), and the mean arterial pressure, K value, peripheral resistance and blood viscosity of group B were significantly higher than those of the control group ( t value was 4.303, 2.776, 2.571, 2.447 and 3.078, respectively, all P<0.05).The incidences of small for gestational age (SGA) infants and neonatal asphyxia in T3 group were significantly higher than other groups (t value was 7.38 and 7.81, respectively, both P<0.05), and the incidences of premature delivery and dead birth in T4 group were significantly higher than other groups (t value was 9.38 and 5.99, respectively, both P<0.05).Conclusion Ultrasound monitoring blood flow changes of preeclampsia can significantly enhance the detection rates of perinatal SGA and stillbirths, and make it convenient for early intervention in clinics.关键词
