Sexual behavior and activity in Chinese pregnant women

Objective.  To evaluate sexual activities, attitudes, and complications related to intercourse among Chinese pregnant women and to study their source of the information.

Left ventricular diastolic function during normal pregnancy: assessment by spectral tissue Doppler imaging

Tissue Doppler imaging (TDI) is an echocardiographic technique for assessing the diastolic function that is relatively independent of preload. Since loading conditions change significantly during pregnancy, a load‐independent technique will give a more accurate assessment of diastolic function in pregnant women. The aim of this study was to evaluate maternal diastolic function using tissue Doppler imaging.

High incidence of obstetric interventions after successful external cephalic version

Objective To investigate the delivery outcome after successful external cephalic version (ECV).

Maternal experience of pain during external cephalic version at term

Background.  This study was designed to investigate maternal pain perception during external cephalic version (ECV).

Outcome of labour after successful external cephalic version at term complicated by isolated transient fetal bradycardia.

Objectives To investigate factors associated with the occurrence of transient fetal bradycardia after external cephalic version, and labour outcome after isolated transient fetal bradycardia.

Pitfalls in diagnosis of interstitial pregnancy.

Background.  To determine the incidence and reasons for misdiagnosis in interstitial ectopic pregnancy.

The effect of learning curve on the outcome of caesarean section

Objective  To evaluate the operative outcomes when trainees first perform caesarean sections independently.

Prediction of intrapartum Cesarean delivery for non‐reassuring fetal status after a successful external cephalic version by a low pre‐version pulsatility index of the fetal middle cerebral artery

To determine whether a pre‐version Doppler assessment of fetal cerebral and umbilical blood flow can predict the ultimate need for intrapartum Cesarean delivery after a successful external cephalic version (ECV).

Quantification of contact surface pressure exerted during external cephalic version

Background.  The amount of force exerted on the uterus and fetus during external cephalic version (ECV) may be associated with fetal effects or complications. We have designed an instrument to quantify the contact pressure exerted during the performance of ECV, as an indirect measurement of the applied force.

The influence of fetal position on amniotic fluid index and single deepest pocket.

To evaluate the effect of fetal position on measurement of amniotic fluid index (AFI) and of the single deepest pocket (SDP).
