Abstract

<abstract abstract-type="main" id="anae12534-abs-0001"> <title>Summary</title> <p>The bougie is a popular tool in difficult intubations. The hold‐up sign is used to confirm tracheal placement of a bougie. This study aimed to establish the potential for airway trauma when using this sign with an Eschmann re‐usable bougie or a Frova single‐use bougie. Airways were simulated using a manikin (hold‐up force) and porcine lung model (airway perforation force). Mean (SD) hold‐up force (for airway lengths over the range 25–45 cm) of 1.0 (0.4) and 5.2 (1.1) N were recorded with the Eschmann and Frova bougies, respectively (p &lt; 0.001). The mean (SD) force required to produce airway perforation was 0.9 (0.2) N with the Eschmann bougie and 1.1 (0.3) N with the Frova bougie (p = 0.11). It is possible to apply a force at least five times greater than the force required to produce significant trauma with a Frova single‐use bougie. We recommend that the hold‐up sign should no longer be used with single‐use bougies. Clinicians should be cautious when eliciting this sign using the Eschmann re‐usable bougie.</p> </abstract>
