“…In the present study, a series of sequential photographs were taken to indicate how the introducer uncoiled following initial shaping, following earlier studies [5,22,23]. Siena et al devised a method to assess the maintenance of curvature, which could be included in a standard for introducers [24,25].…”

An assessment of introducers used for airway management

Summary Different introducers are available to assist with tracheal intubation. Subtle differences in the design of introducers can have a marked effect on safety and performance. The Difficult Airway Society’s Airway Device Evaluation Project Team proposal states that devices should only be purchased for which there is at least a case–control study on patients assessing airway devices. However, resources are not currently available to carry out a case–control study on all introducers available on the market. This study comprised a laboratory and manikin‐based investigation to identify introducers that could be suitable for clinical investigation. We included six different introducers in laboratory‐based assessments (design characteristics) and manikin‐based assessments involving the participation of 30 anaesthetists. Each anaesthetist attempted placement in the manikin’s trachea with each of the six introducers in a random order. Outcomes included first‐time insertion success rate; insertion success rate; number of attempts; time to placement; and distance placed. Each anaesthetist also completed a questionnaire. First‐time insertion success rate depended significantly on the introducer used (p = 0.0016) and varied from 47% (Armstrong and P3) to 77% (Intersurgical and Frova). Median time to placement (including oesophageal placement) varied from 10 s (Eschmann and Frova) to 20 s (P3) (p = 0.0025). Median time to successful placement in the trachea varied from 9 s (Frova) to 22 s (Armstrong) (p = 0.037). We found that the Armstrong and P3 devices were not as acceptable as other introducers and, without significant improvements to their design and characteristics, the use of these devices in studies on patients is questionable. The study protocol is suitable for differentiating between different introducers and could be used as a basis for assessing other types of devices.

“…The authors recently presented the concept of accurate testing systems, including developing a Shape Retention Testing System (SRTS) capable of accurately measuring shape retention characteristics. 4 The SRTS aims to resolve issues identified from previous studies that fail to fully consider issues such as reliability, measurement accuracy, standardisation of applied pressures, calibration, data acquisition equipment accuracy, and repeatability of positional tracking.…”

Equipment design and selection can contribute to the success or failure of difficult airway management. The design of medical devices/testing systems completed by multidisciplinary design teams that include healthcare professionals can significantly influence device success or failure. This paper presents an overview of the design tasks used to develop the Shape Retention Testing System (SRTS) for the assessment of bougie introducers. By using a multidisciplinary design team that includes healthcare professionals, critical design tasks such as design criteria generation, product design specification (PDS) generation, focused design approaches, and iterative design processes have ensured essential feedback is collected to influence the SRTS's design and manufacture.
