Assessment of internal diameter and cross-sectional area of right internal jugular vein pre-induction and post-intubation.
This prospective observational study compared the internal diameter and cross-sectional area of the right internal jugular vein pre-induction and post-initiation of positive pressure ventilation. Twenty patients undergoing coronary artery bypass surgery were studied. ⋯ There was a statistically significant increase in both measurements post-intubation. This study suggests that it may be easier and safer to perform cannulation of RIJV after institution of intermittent positive pressure ventilation in patients in the modified Trendelenburg position.

Biography Historical ArticleHubert Ingham Clements: a pioneer of Australian anaesthesia.
Hubert Ingham Clements was an inventor, designer and engineer who manufactured many pieces of apparatus for use in the scientific and medical practice, particularly in the field of anaesthesia from 1917 when he designed and manufactured suction pumps and anaesthetic machines. His products were ingenious, light and portable where desirable, but sturdy, extraordinarily reliable, of low maintenance and high performance. His contribution to the specialty of anaesthesia is acknowledged.

Randomized Controlled Trial Comparative Study Clinical TrialComparative study between propofol in a long-chain triglyceride and propofol in a medium/long-chain triglyceride during sedation with target-controlled infusion.
This study was performed to compare the pharmacological characteristics of propofol in an emulsion of both medium- and long-chain triglycerides (MCT/LCT) with those of propofol in an LCT emulsion, by measuring the sedative level and the plasma concentration of propofol during sedation using a target-controlled infusion (TCI) technique. Forty ASA 1 or 2 adult patients who required spinal anaesthesia for surgery were enrolled in this study. The patients were divided into two groups: a propofol LCT group (n = 20) and a propofol MCT/LCT group (n = 20). ⋯ There were no significant differences between the two groups in BIS index or in plasma concentration of propofol at each predicted concentration. Computer-generated TCI of propofol MCT/LCT during sedation is comparable with that of propofol LCT with respect to pharmacokinetics and pharmacodynamics. The formulation of MCT/LCT has a beneficial effect with respect to less pain on injection.

ReviewOutcome-based clinical indicators for intensive care medicine.
The clinical indicator is a tool used to monitor the quality of health care. Its use in the Intensive Care Unit (ICU) is desirable for many reasons: the maintenance of minimum standards, the development of best practice and the delivery of cost-effective health care. ⋯ Monitoring of adverse events, system descriptors, and resource indicators is valuable but they have a limited relationship to the quality of care. ICU mortality prediction models provide a global measure of quality and, despite their inherent deficiencies, remain one of the most robust and useful clinical indicators.

Historical ArticleAnaesthesia in Hong Kong and the Faculty of Anaesthetists: 25 years of co-operation.
The development of anaesthetic services in Hong Kong started about five years after the Faculty of Anaesthetists, RACS, was founded. A nucleus of trained anaesthetists there sought assistance from the Faculty to establish adequate training posts and courses of instruction, and hence to provide consultants with an internationally accepted qualification. This paper describes the major features of the early decades of this development.
