Several previous publications demonstrate the significant haemodynamic effects of oxytocin in healthy pregnant women, but there is only one publication of the oxytocin effects in women with severe preeclampsia. We investigated the haemodynamic effects of oxytocin in women with severe preeclampsia using invasive haemodynamic monitoring. ⋯ The haemodynamic effects of oxytocin in women with severe preeclampsia may be less predictable compared to findings in healthy pregnant women, suggesting that oxytocin should be given with caution in women with severe preeclampsia.

ReviewImaging evaluation of the pregnant patient with suspected pulmonary embolism.
Pulmonary embolism is the leading cause of maternal death in the developed world. The clinical diagnosis of pulmonary embolism is particularly challenging in pregnant patients as physiologic changes of pregnancy can mimic symptoms of pulmonary embolism or deep venous thrombosis. Clinical decision and imaging algorithms for venous thromboembolic disease have been proposed in the literature for the general population, but have not undergone wide-scale validation in pregnant patients. ⋯ Additional factors beyond test performance must be weighed during pregnancy: radiation exposure to the fetus and maternal breast tissue, the safety of intravenous contrast administration and the diagnostic accuracy of the various testing options so that diagnosis and proper management are not delayed. The epidemiology of pregnancy-related venous thromboembolic disease and the different diagnostic methods are reviewed, with emphasis on the pregnant patient. Finally, a diagnostic imaging algorithm is proposed for the evaluation of the pregnant patient when a clinical suspicion of pulmonary embolism exists.

Case ReportsMultiple complications following the use of prophylactic internal iliac artery balloon catheterisation in a patient with placenta percreta.
The incidence of placenta praevia/accreta is increasing, placing women at significant risk of postpartum haemorrhage with associated morbidity and mortality. National guidelines recommend prophylactic placement of internal iliac artery balloon occlusion catheters for women with abnormal placentation. ⋯ She developed bilateral pseudoaneurysms, unilateral arterial rupture and compromised vascular supply to her right leg secondary to thrombus formation, and suffered massive haemorrhage, both despite and as a result of intervention. This is the first case report of multiple complications in an obstetric patient after temporary internal iliac balloon occlusion in an elective setting.
