The Tasmanian devil, Sarcophilus harrisii, is the largest extant marsupial carnivore. In 1996, a debilitating facial tumor was reported. It is now clear that this is an invariably lethal infectious cancer. The disease has now spread across the majority of the range of the species and is likely to occur across the entire range within 5 to 10 years. The(More)
Trypanosomes were observed in 38% of blood smears from southern brown bandicoots (Isoodon obesulus) and in 10% of blood smears from eastern barred bandicoots (Perameles gunnii). This is the first record of such hemoparasites in Tasmanian marsupials. There appeared to be a statistically significant size difference between trypanosomes found in the 2(More)
BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine, and may be of particular use in the day-case setting. However, there are few data comparing the actions of plain and hyperbaric solutions of this drug. METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under(More)
We investigated the effect of leg position on the depth of the sciatic nerve and quality of ultrasound images taken at the proximal and mid-thigh level. Twenty-one volunteers with average body mass index were recruited to represent the younger population receiving sciatic nerve blocks for sports injury surgery. The volunteers were placed in the lateral(More)
We studied the effect of cricoid pressure and lateral tilt on airway patency during ventilation by facemask in a simulated obstetric setting. The lungs of 50 patients were ventilated by facemask and Guedel airway using a Nuffield Penlon 200 ventilator and Bain system with standard settings. Expired tidal volumes and peak inspiratory pressures were recorded(More)
There is a requirement for a basic approach to the provision of analgesia on the battlefield using the morphine autojet. Assuming there is cardiorespiratory stability and no contraindications to opioid therapy, morphine can be administered intramuscularly to a serviceman in pain on a 2 hourly basis provided that there are no adverse effects on the(More)
transient neurologic symptoms after intrathecal injection of lidocaine. Anesthesiology 2002; 97: 257±8 7 Sumi M, Sakura S, Kosaka Y. Intrathecal hyperbaric 0.5% tetracaine as possible cause of transient neurological toxicity. Anesth Analg 1996; 82: 1076±7 8 Sakura S, Sumi M, Sakaguchi Y, et al. The addition of phenylephrine contributes to the development of(More)
Until recently epidural abscess was considered a rare, almost theoretical, complication of central nerve block, but anecdotal reports suggest that this is no longer the case. Thus a review of the risk factors, pathogenesis, clinical features and outcome of this condition is appropriate, the primary aim being to make recommendations on best anaesthetic(More)
Regional anaesthesia for bilateral upper limb surgery can be challenging, yet surgeons are becoming increasingly interested in performing bilateral procedures at the same operation. Anaesthetists have traditionally avoided bilateral brachial plexus block due to concerns about local anaesthetic toxicity, phrenic nerve block and pneumothorax. We discuss these(More)
