ReviewApplying the cell-based coagulation model in the management of critical bleeding.
The cell-based coagulation model was proposed 15 years ago, yet has not been applied commonly in the management of critical bleeding. Nevertheless, this alternative model may better explain the physiological basis of current coagulation management during critical bleeding. ⋯ From a practical perspective, applying the cell-based coagulation model also explains why new direct oral anticoagulants are effective systemic anticoagulants even without affecting activated partial thromboplastin time or the International Normalized Ratio in a dose-related fashion. The cell-based coagulation model represents the most cohesive scientific framework on which we can understand and manage coagulation during critical bleeding.

Australian and New Zealand Anaesthetic Allergy Group/Australian and New Zealand College of Anaesthetists Perioperative Anaphylaxis Management Guidelines.
Anaphylaxis is an uncommon but important cause of serious morbidity and even mortality in the perioperative period. The Australian and New Zealand College of Anaesthetists (ANZCA) with the Australian and New Zealand Anaesthetic Allergy Group (ANZAAG) have developed clinical management guidelines that include six crisis management cards. The content of the guidelines and cards is based on published literature and other international guidelines for the management of anaesthesia-related and non-anaesthesia-related anaphylaxis. ⋯ These guidelines are intended to apply to anaphylaxis occurring only during the perioperative period. They are not intended to apply to anaphylaxis outside the setting of dedicated monitoring and management by an anaesthetist. In this paper guidelines will be presented along with a brief background to their development.

Biography Historical ArticleSt John's Hospital (Morton House), Launceston, Australia: A history of the hospital and Dr William Russ Pugh's first operations under ether.
On 7 June 1847, William Russ Pugh, MD, performed two operations at the St John's Hospital and Self-Supporting Dispensary, Launceston, Tasmania, while his patients were rendered insensible by the inhalation of sulphuric ether. These operations are the earliest documented surgical operations under ether in Australia. St John's Hospital officially opened on 1 September 1845. ⋯ The name Morton House may honour William T. G. Morton, MD, the Boston dentist who performed the first public demonstration of surgical etherisation on 16 October 1846.

Changes in cerebral oxygen saturation and haemoglobin concentration during paediatric cardiac surgery.
Although near-infrared spectroscopy (NIRS) enables bedside assessment of cerebral oxygenation, it provides little information on the cause of deoxygenation. The authors aimed to investigate the changes in cerebral oxygenation and haemoglobin concentration and their associations during paediatric cardiac surgery in order to elucidate the physiology underlying cerebral deoxygenation. An observational retrospective study on 399 patients who underwent paediatric cardiac surgery was conducted. ⋯ On the contrary, there was no evidence for a change in [HbO2] (+0.45 μmol/l [-4.76, +5.30], P=0.42). Cerebral oxygen saturation decreased after paediatric cardiac surgery and the decrease was greater in patients of higher risk groups. The increase in [HHb] was considered to play a predominant role in the cerebral deoxygenation noted, in particular in higher RACHS-1 category groups.
