Abstract：

Objective To explore clinical features of severe preeclampsia patients with adverse outcome, and the risk factors of adverse outcomes. Methods From Jan. 2008 to Dec. 2009 149 severepreeclampsia impatients who occurred adverse outcome enrolled as case,and 278 severe preeclampsia impatientswithout adverse outcome at the same period enrolled as control. The clinical features between the two groups were compared and the risk factors were investigated. Results No significant differences were found between the two groups in maternal age,times of previous prenancies. The gestation ages at the onset of preeclampsia and at delivery in the cases were less than controls(P ＜ 0. 05). There was significant difference in irregular antenatal checks between the two groups(x2 = 8. 515, P ＜ 0. 05). Proterinuria and the level of oedema in cases were higher than controls( P ＜ 0. 05). Fetal growth restriction (FGR) occurred more frequently in the cases (P ＜0. 05). Indirect bilirubin, total bilirubin, glutamic oxalacetic transaminase, glutamic pyruvic transaminase, uric acid, creatinine, white blood cell, thrombin time, D-dimeride of cases were higher than those of controls(Ps ＜0. 05). Albumin, platelet and profibrin of cases were lower than those of controls(Ps ＜ 0. 05 ＝. Multivariate logistic analysis showed that the gestation ages at the onset of preeclampsia, regular antenatal checks were significantly associated with adverse outcome(OR = 0. 899, P ＜ 0. 001; OR = 0. 600, P = 0. 022, respectively ＝Indirect bilirubin and D-dimeride were significantly associated with preeclampsia complications(OR = 1. 533,P =0. 010; OR = 1.001, P = 0. 003, respectively). Mean arterial pressure and creatinine were significantly associated with eyeground changes(respectively OR = 1. 030,P = 0. 048; OR = 1. 025, P = 0. 022, respectively).Regular antenatal checks was associated with dead fetus(OR = 0. 317, P = 0. 046). No significant differenceswere found between the two group in uterine-incision delivery(P ＞ 0. 05). Incidence rate of low birth weight infants and postpartum hemorrhage of cases were higher than controls and Apgar score was lower in cases than controls( all P ＜0. 05＝. Conclusion The gestation ages at the onset of preeclampsia,regular antenatal checks,fetal distress were risk factors for preeclampsia adverse outcome. Patients with.high indirect bilirubin and Ddimeride are more likely to suffer adverse pregnancy outcomes.     

Cerebroplacental Doppler ratio and adverse perinatal outcomes in intrauterine growth restriction: evaluating the impact of using gestational age-specific reference values.

OBJECTIVE: The purpose of this study was to compare the impact of using gestational age-specific reference levels of the cerebroplacental Doppler ratio (CPR) with categorical threshold in the prediction of adverse perinatal outcomes in growth-restricted pregnancies. METHODS: A retrospective cohort study of cases of intrauterine growth restriction over a 3-year period was conducted. The umbilical artery and middle cerebral artery pulsatility indices were converted to CPRs. The efficacy of using gestational age-specific reference levels of CPRs in predicting adverse outcomes was compared with the use of a CPR of less than 1.08. Adverse perinatal outcomes evaluated included cesarean delivery for nonreassuring fetal heart tones, umbilical artery pH less than 7.0, 5-minute Apgar scores less than 7.0, intraventricular hemorrhage greater than grade 2, periventricular leukomalacia, respiratory distress syndrome, and perinatal death. RESULTS: Of 183 pregnancies meeting our inclusion criteria, there were 70 with at least 1 adverse outcome. With the use of a CPR ratio below the 5th percentile for gestational age, the sensitivity, specificity, and positive and negative predictive values for predicting an adverse outcome were 65%, 73%, 73%, and 65%, respectively, with an odds ratio (95% confidence interval) of 5.2 (1.4-19.4; area under the receiver operating characteristic curve, 0.69). With a CPR threshold of less than 1.08, the sensitivity, specificity, and positive and negative predictive values were 72%, 62%, 68%, and 67%, with an odds ratio (95% confidence interval) of 4.2 (1.2-15.3; area under the receiver operating characteristic curve, 0.67). CONCLUSIONS: An abnormal CPR is associated with adverse perinatal outcomes in growth-restricted fetuses. The accuracy of using gestational age-specific reference levels was similar to that of using a categorical threshold.     

Dexamethasone on absent end-diastolic flow in umbilical artery,in growth restricted fetuses from early-onset preeclamptic pregnancies and the perinatal outcome

BackgroundAbsent end-diastolic flow (AEDF) in the umbilical artery (UA) worsens the already poor prognosis of growth-restricted fetuses (GRFs) in pregnancies complicated by early-onset preeclampsia with severe features (ESP).MethodWe assessed the correlation between the effect of maternal dexamethasone (Dex) on AEDF in the UA and perinatal outcomes, in 59 GRFs from EPS-complicated pregnancies. The maternal outcome was also evaluated.ResultsThe mean maternal age at inclusion was 22.4 ± 5.9 years. Dex transiently restored EDF in the UA in 38 (64.4%) cases (trAEDF group), but in 21 (35.6%) patients, the flow was persistently absent (prAEDF group). The effect lasted up to the 4th day.The gestational age at diagnosis, number of days from admission until delivery, and fetal weight were significantly lower in the prAEDF group than in the trAEDF group (p < .05). The same group had a significantly increased rate of fetal proximal deterioration, low APGAR scores, neonatal hypoxia, assisted ventilation, mild intraventricular haemorrhage (I/II), and respiratory distress syndrome, as well as maternal deterioration, especially in cases of resistant hypertension (p < .05). Although the rates of fetal acidemia and perinatal mortality in the prAEDF group were respectively three times and two times higher, the differences were not significant (p > .05).ConclusionsThe Dex no-effect on UA Doppler in GRFs with AEDF in the UA, in EPS-complicated pregnancies, can be a useful marker for a higher risk of proximal fetal deterioration, poor state at delivery, neonatal hypoxic complications, and worsening maternal condition, but not for perinatal mortality. The findings also highlight the alarmingly younger age of patients with EPS. Finally, all these pregnancies should be monitored in a complex multidisciplinary manner in tertiary referral units.

Key message

• The effect of dexamethasone on absent end-diastolic flow in the umbilical artery in growth-restricted fetuses from pregnancies complicated by early-onset preeclampsia with severe features can be a useful prognostic factor for perinatal outcomes.
