  • costs of replacement of Anaesthetic Equipment projected expenditure for clinical Anaesthetic Equipment in a teaching health district
    Anaesthesia, 2007
    Co-Authors: N M Schofield

    A study was made of all the Anaesthetic Equipment in clinical use to substantiate estimates of the cost of its replacement on four hospital sites. The years during which replacement was likely to become necessary were estimated from the list compiled and an existing full inventory, together with costs at 1986 prices. The predicted costs for each year until 2000 AD were derived. To these were added sums required to make good existing shortfalls and to introduce a moderate amount of Equipment incorporating newer technology. The totals showed that the capital currently available in the health district is sufficient only for Anaesthetic Equipment and requires a substantial increase to replace medical apparatus belonging to all specialties already in routine clinical use. Health authorities must be given detailed projections of these costs.

  • Basic simulations for anaesthetists. A pilot study of the ACCESS system.
    Anaesthesia, 2007
    Co-Authors: A. J. Byrne, P. J. Hilton, J.n. Lunn

    Summary This paper describes the design and initial testing of the ACCESS (Anaesthetic Computer Controlled Emergency Situation Simulator) system, which has been designed to simulate Anaesthetic emergencies with the aim of providing training for junior doctors. The simulations require little or no capital expenditure with minimal use of time by staff or trainees. They are based on standard Anaesthetic Equipment, with a microcomputer providing an image of commonly used instruments. Problems are presented as scenarios administered by the teacher, and test the skills of the pupil. During 64 scenarios, five trainees caused two‘deaths’and solved the problems in a median time of2.5min, while an experienced group of anaesthetists caused one‘death’and took 1.8 min. The simulation was rated by the pupils as easy to use, realistic and a valuable educational tool.

  • an evaluation of the hamo ls 76 washing drying and disinfecting machine for Anaesthetic Equipment
    Journal of Hospital Infection, 1992
    Co-Authors: M D Smith, M L Pocklington, M C Kelsey

    Abstract This report evaluates a machine designed to wash, disinfect and dry Anaesthetic Equipment. Following adjustments to the program these objectives could be reliably achieved within a reasonable time. Multifunction machines should be considered for future use in Sterile Service Departments, although a careful assessment of the workload capacity should be made before purchase.

  • Inspiratory valve malfunction in a circle system: pitfalls in capnography
    Canadian journal of anaesthesia = Journal canadien d'anesthesie, 1992
    Co-Authors: A. Yasodananda Kumar, K. Bhavani-shankar, H. Moseley, Yvette Delph

    Capnography is a useful technique in monitoring the integrity of Anaesthetic Equipment such as the malfunctioning of unidirectional valves in circle system. However, the lack of a precise mechanism in existing capnographs to identify the start of inspiration and the beginning of expiration in the capnograms, makes the analysis of the carbon dioxide waveforms during inspiration difficult and thus results in inaccurate assessment of rebreathing. We report a case where, during the malfunction of the inspiratory unidirectional valve in the circle system, the capnograph failed to detect the presence of substantial rebreathing. Critical analysis of the capnogram recorded during the malfunction revealed that there was substantial rebreathing which was underestimated by the capnograph as it reports only the lowest CO2 concentration rebreathed during inspiration in such abnormal situations.

  • Investigation of phthalate release from tracheal tubes
    Anaesthesia, 2012
    Co-Authors: W. Morton, Antony Robert Wilkes, Carsten Theodor Muller, Naomi Goodwin, Judith Elizabeth Hall

    Summary Phthalates are chemicals used extensively in the manufacture of plastics for their desirable physical characteristics. In addition to enhancing the performance of plastics, phthalates have a number of undesirable effects, principally endocrine disruptor effects, that may have adverse effects on reproductive development and functioning. As a result, they have been banned from the manufacture of children’s toys. Despite this, they continue to be used in the manufacture of medical devices, including Anaesthetic Equipment. This study aimed to assess phthalate release from five brands of tracheal tube. Using gas chromatography–mass spectrometry, we analysed phthalate concentrations from samples of ultra pure water in which tracheal tubes had been submerged. Phthalate concentration increased from 6.7 to 149 μg.l−1 over a period of 4.8 days. Phthalate release from Anaesthetic Equipment has not previously been documented over short time periods and raises the possibility of iatrogenic endocrine disruption with routine anaesthesia.

  • The history of Anaesthetic Equipment evaluation in the United Kingdom: lessons for developing future strategy
    Anaesthesia, 2011
    Co-Authors: Antony Robert Wilkes, Jaideep J. Pandit, E. O’sullivan

    Recent guidance published by the Association of Anaesthetists of Great Britain and Ireland encourages the purchase of Equipment based on evidence of safety and performance. For many years, evidence of the safety and performance of Anaesthetic Equipment was published by various government departments and agencies. However, these schemes were gradually eroded over time such that many devices entered the market with little or no clinical evidence of their efficacy. This recently led to the Difficult Airway Society’s issuing guidance to its members on how best to select new airway devices; guidance that was based on the available evidence. This article provides a short history of the evaluation of Anaesthetic Equipment in the United Kingdom.
