Randomized Controlled TrialThe use of aortic occlusion balloon catheter without fluoroscopy for life-threatening post-partum haemorrhage.
This article describes the use of a balloon catheter introduced via the femoral artery into the abdominal aorta without the use of fluoroscopy to stabilize six patients with life-threatening post-partum haemorrhage. The femoral artery was localized blindly or with the use of ultrasound. ⋯ In these six cases, the procedures were carried out by interventional radiologists. However, this procedure can also be performed by anaesthesiologists or surgeons who are trained in vascular access techniques.

Venous flow dynamics during spinal block in normotensive and hypertensive elderly patients: a duplex ultrasonographic study.
Spinal block induces hyperkinetic change in lower extremity blood flow. We compared the venous flow dynamic responses to spinal block in normotensive and hypertensive elderly patients. ⋯ Blood pressure and flow dynamics in the popliteal vein showed similar changes during spinal anaesthesia in elderly patients taking antihypertensive medication and normotensive patients, despite differences in baseline values.

The saphenous nerve and its relationship to the nerve to the vastus medialis in and around the adductor canal: an anatomical study.
Recently, ultrasound-guided saphenous nerve blocks within and distal to the adductor canal have shown success. However, a potential side effect is an unintentional block of branches of the nerve to the vastus medialis resulting in undesired motor weakness. ⋯ Knowledge of this anatomy may help establish a safe region in preventing motor blockade when performing saphenous nerve blocks.

Multicenter StudyIs day surgery safe? A Danish multicentre study of morbidity after 57,709 day surgery procedures.
Day surgery is expanding in several countries, and it is important to collect information about quality. The aim of this study was to assess morbidity and unanticipated hospital visits 0-30 days post-operatively in a large cohort. ⋯ This large-scale Danish national study confirmed that day surgery is associated with a very low rate of return hospital visits. Despite the rapid expansion of day surgery, safety has been maintained, major morbidity being very rare, and no deaths being definitely related to day surgery.
