BACKGROUND: Intraoperative haemodynamic monitoring is carried out in high-risk surgical patients, often using invasive methods, including pulmonary artery catheterisation. Early goal-directed therapy in high-risk surgical patients reduces tissue hypoxia, organ failure and improves outcomes. Significant maternal morbidity arises as a result of perioperative haemorrhage. At present, heart rate and brachial blood pressure are used as proxy markers to aid in fluid resuscitation, however, we know that these exhibit minimal change during early stages of shock, and are poor indicators of the adequacy of therapeutic intervention...

INTRODUCTION: Fetal growth restriction (FGR) is associated with poor perinatal outcomes. Screening and prevention tools for FGR, such as uterine artery Doppler imaging and aspirin, underperform in high-risk groups, compared with general antenatal populations. There is a paucity of sensitive screening tests for the early prediction of FGR in high-risk pregnancies. MATERIALS AND METHODS: This was a prospective observational study based in a dedicated antenatal hypertension clinic at a tertiary UK hospital...
