“…Though unavailable to our team, the de livery of vapour anaesthesia via drawover equipment has proven benefi ts over plenum rebreather systems in terms of reduced reliance on heavy or complex ancillary equipment and oxygen supplies 4,5,11,12 and as such has been advocated as suitable for disaster, remote area or military anaes thesia 4,5,[11][12][13] . Indeed, drawover equipment is routinely carried by Aus tralian Defence Force medical teams, with Taylor and co-workers 1 reporting the use of both intravenous ketamine and drawover halothane/isofl urane techniques in over 200 surgical procedures following the 1998 Papua New Guinea tsunami.…”

We report on the experience of a 23-member Australian medical team in Banda Aceh, Indonesia, following the 2004 Boxing Day tsunami. Arriving 13 days after the tsunami that devastated the city, killed 100,000 of its inhabitants and injured thousands more, we carried out 130 surgical procedures in austere conditions over a 12-day period. Most surgery was peripheral, principally for plastic surgical or orthopaedic procedures to lower limb injuries. Intravenous ketamine anaesthesia was the technique of choice, with good surgical conditions and few significant side-effects.

“…Vapour output can be increased by arranging two units in the series and is required for induction with Sevoflurane. [1718] It is very convenient for field use and can be used in series with a self-inflating bag or for halothane induction in series with an EMO[19] [Figure 7]. …”

Vapourisers: Physical principles and classification

Vapourisers have evolved from rudimentary inhalers to the microprocessor controlled, temperature compensated and flow sensing devices, which are universal today. The improvements in the design was influenced by the development of potent inhalational anaesthetics, unique properties of some agents, a deeper understanding of their mechanism of action, inherent flaws in the older vapourisers, mechanical problems due to thymol deposition, factors influencing their output such as temperature and pressure variations. It is important to review the principles governing the design of the vapouriser to gain insight into their working. It is fascinating to know how some of the older vapourisers, popularly used in the past, functioned. The descendant of Oxford Miniature Vapourizer, the Triservice vapouriser is still a part of the military anaesthesia draw over equipment meant for field use whereas the Copper Kettle the first precision device is the fore-runner of the Tec 6 and Aladdin cassette vapouriser. Anaesthesia trainees if exposed to draw over techniques get a deeper understanding of equipment and improved skills for disaster situations. In the recent advanced versions of the vapouriser a central processing unit in the anaesthetic machine controls the operation by continuously monitoring and adjusting fresh gas flow through the vapouriser to maintain desired concentration of the vapour.

“…Liu & Dhara tested the vaporiser on a flow-bench and suggested that the output should be suitable [8]. Brook and Perndt subsequently used sevoflurane clinically and stated that it was possible to perform an inhalation induction with two vaporisers [9] but the modern penchant for gas induction with sevoflurane has been difficult to satisfy with the TSAA. The OMV was designed when the relatively potent halothane was the volatile agent of choice and maximum outputs are limited when 4 MAC of sevoflurane is the target.…”

The Triservice Anaesthetic Apparatus was designed around 30 years ago as a robust and highly portable anaesthesia delivery system for medical support to airborne operations and it has been the core anaesthesia system for the Defence Medical Services since then. Over this period there have been a number of equipment changes but issues remain which are in part mitigated by recent training developments. This article reviews these changes and developments and considers the future of this equipment.• Minimal reliance on compressed gases and electrical supplies • Robust • Compact and portable • Simple to operate • Able to withstand climatic extremes • Easily maintained and serviced • Economical in use • Versatile in the use of volatile agents • Versatile with regard to patient age/size group.bmj.com on July 6, 2015 -Published by
