The objective of this paper is to characterise the frequency of different surgical techniques for targeting the lateral ventricle in shunt surgery and the attitudes of Australasian neurosurgeons and advanced neurosurgical trainees to stereotactic adjuncts. Secondarily, we aim to learn from and collate the practical experiences of neurosurgeons for those(More)
BACKGROUND The optimal site for local anesthetic placement during ultrasound-guided infraclavicular block remains controversial. METHODS Patients were randomized to receive lidocaine 2% 30 mL as a single injection posterior to the axillary artery (n = 51) or a triple injection ideally adjacent to each brachial plexus cord (n = 49). Pinprick sensory and(More)
BACKGROUND Medical graduate interest in surgery has declined and medical students are less capable in anatomy than they once were. Declining interest in surgery is because of factors, including growing number of women entering medical school. There has been less emphasis in teaching anatomy at various medical schools in recent years. The aim of this study(More)
BACKGROUND Prior to cholecystectomy it is important to assess the common duct for choledocholithiasis. Given that a proportion of common duct stones will pass without incident and that methods of removal of these stones are potentially morbid, it would be very useful to have a test that identified only those stones that need intervention.

AIM The presence of a trauma system has been associated with improved outcomes in patients with traumatic brain injury (TBI) by speeding up transfers to a neurosurgical centre. Improved outcomes are associated with time to neurosurgical intervention for those with significant extradural and subdural haemorrhages of less than 4 hours. To compare the outcomes(More)
