Case ReportsUse of Doppler ultrasound in the management of uteroplacental perfusion during cardiopulmonary bypass in pregnancy.
Cardiopulmonary bypass, the extreme of non-obstetric surgery during pregnancy, presents unique challenges to minimize maternal and fetal risk. We present our experience with a woman who was diagnosed with a left atrial myxoma following an ischemic cerebrovascular accident. ⋯ We recommend using intermittent Doppler ultrasound as a non-invasive real-time assessment of uteroplacental perfusion during non-obstetric surgery in pregnancy. Monitoring of perfusion facilitates active feedback for appropriate in utero resuscitation in these cases.

Prophylactic abdominal aorta balloon occlusion during caesarean section: a retrospective case series.
The management of patients with morbidly adherent placenta has been described using vascular balloon catheters placed in the iliac arteries, but rarely in the aorta. This case series presents our experience with prophylactic lower abdominal aorta balloon occlusion in 45 women. ⋯ Prophylactic lower abdominal aorta balloon occlusion has the potential to reduce intraoperative blood loss, transfusion and hysterectomy rate in patients with morbidly adherent placenta undergoing caesarean section. Careful patient selection is critical as the technique may be associated with potentially serious complications.

Although cardiac arrest in pregnancy is rare, it is important that all individuals involved in the acute care of pregnant women are suitably trained, because the outcome for both mother and fetus can be affected by the management of the arrest. Perimortem caesarean delivery was first described in 715 BC. Initially the procedure was performed principally for religious or political reasons. ⋯ While evidence is limited, it is probable that both maternal and fetal survival are improved with early delivery by perimortem caesarean delivery. More importantly, no evidence was found from case report reviews that either maternal or fetal survival was worsened. Perimortem caesarean delivery therefore remains a key consideration in the management of maternal arrest from the mid second trimester.
