Objective To test the hypothesis that suboptimal factors in perinatal care services resulting deaths were more common among immigrant mothers from Horn of Africa, when compared with Swedish mothers. Design A audit, comparing cases children African immigrants residing Sweden, a stratified sample native women. Population and setting Sixty‐three east women delivered hospitals 1990–1996, 126 Time death type hospital stratified. Main outcome measures Suboptimal services, categorised as maternal,...

Eighteen pregnancies with nonimmune hydrops fetalis were referred for fetal echocardiography to rule out congenital heart disease. In 14 of these cases, pulsating blood velocities recorded in the umbilical vein, which a normal population had nonpulsatile velocity pattern. The four cases without pulsations vein found have intrauterine viral infections. last 10 examined, venous reflect abnormal central during atrial systole suggesting increased pressure. Right ventricular shortening fraction...

Objective To compare umbilical and uterine artery Doppler in predicting outcome of pregnancies suspected fetal growth restriction (FGR). Design A prospective study included 353 singleton complicated by an FGR fetus. Setting University Hospital setting. Sample Pregnancies diagnosed ultrasound biometry during a 5‐year period.

Abstract Umbilical and arcuate artery blood flow velocity waveforms (FVW) were recorded in 125 normal singleton pregnancies from 20 to 42 weeks of gestation. The FVW analysed for pulsatility index (PI), peak systolic velocity/minimum diastolic ratio (S/D ratio), rising slope (RS) descending (DS). Both the umbilical arteries, values all variables declined with advancing gestation, indicating decreasing placental vascular resistance. PI was unaffected by fetal heart rate, but negatively...

Anal sphincter rupture is a serious complication of vaginal delivery and almost half the affected women have persistent defecatory symptoms despite adequate primary repair. During past decade, incidence anal ruptures has been increasing in Sweden currently estimated to occur 2.5% deliveries.

Studies on blood flow velocity in the fetal middle cerebral artery have revealed signs of brain sparing chronic hypoxia. These can disappear terminal case, but whether this applies to whole or only parts it is unknown.Velocity waveforms cerebral, anterior and posterior arteries were recorded 221 pregnancies complicated by pregnancy-induced hypertension. The presence (pulsatility index < 2 standard deviations) was noted correlated outcome pregnancy, including emergency operative intervention...

Abstract High perinatal mortality has been reported in association with the finding of absent end‐diastolic flow velocities umbilical artery. The fetus is known to centralize its circulation during hypoxemia and abnormal venous blood have cases heart failure imminent asphyxia. aim this study was evaluate recorded Doppler ultrasound vein, inferior vena cava middle cerebral artery as predictors survival 17 fetuses or reversed There were five deaths, all having cord pulsations.

Background. Previously, we have found uterine artery blood veloeimetry performed with Doppler ultrasound without vessel visualization to be a poor predictor of perinatal outcome. The aim this study was ascertain whether the combination color imaging method would improve its predictive value. Methods. In cross‐sectional 110 uncomplicated pregnancies, velocity recorded bilaterally from 18 42 weeks gestation obtain reference values for pulsatility index (PI). Using imaging, main located as it...
