Bonfils fiberscope vs GlideScope for awake intubation in morbidly obese patients with expected difficult airways

Airway devices for awake tracheal intubation in adults: a systematic review and network meta-analysis

“…Details of the screening process are illustrated in Supplementary Appendix B. FBs were compared with OSs, channelled VLs, and unchannelled VLs in three, 11,12,21 one, 29 and seven 18,23e28 trials, respectively, and OSs were compared with unchannelled VLs in one trial. 22 No trials compared DLs to any other airway device. The findings of the risk of bias assessment are presented in Figure 1, and only one trial was assessed to be at low risk of bias in all domains.…”

“…12,23,28 In the 10 instances where we needed to clarify details of trial methodology or request missing data, four authors responded with the required information. 21,22,28,29 Characteristics of the RCTs are detailed in Table 1. In all but one of the trials, 12 the operators were classified as experienced, although the level of this experience differed in seven trials 18,21e23,25,26,28,29 and was not specified in three trials.…”

“…Patients received local anaesthesia topicalisation and sedation before the ATI in all trials. ATI was performed through the nasal and oral route in four 11,18,22,27 and eight 12,21,23e26,28,29 trials, respectively. The Bonfils (Karl Storz, Tuttlingen, Germany), Disposcope endoscope (Yangzhou Dex Medical Co., Ltd, Yangzhou, China) and the Shikani (Clarus Medical, Minneapolis, MN, USA) were the OSs in one, 22 one, 12 and two 11,21 trials, respectively, while the Bullard (Olympus America, Center Valley, PA, USA), C-MAC® (Karl Storz, Tuttlingen, Germany), GlideScope® (Verathon Medical, Bothell, WA, USA), McGrath™ (Aircraft Medical, Edinburgh, UK), and the Pentax Airway Scope® (Hoya Service Corporation, Tokyo, Japan) were the VLs in one, 23 one, 18 five, 22,25e28 one, 24 and one 29 trial, respectively.…”

“…It was likely that this extent of heterogeneity was, at least in part, secondary to the variation in the definition of the TTI in these trials. The TTI was timed from the introduction of the specified airway device to the point at which the tracheal tube passed the glottic opening, 21 the pilot balloon of the tracheal tube was inflated, 18 the capnography trace appeared, 11,12,22,24,28 the end-tidal carbon…”

Optical Devices in Tracheal Intubation—State of the Art in 2020

“…Intubation with the Bonfils stylet should be beneficial in patients with suspected cervical spine injury because it is associated with significantly lesser cervical spine movements than with direct laryngoscopy [61,62]. Several studies have assessed Bonfils stylet as a device for awake tracheal intubation in patients with predicted difficult airway [63][64][65]. A relatively large number of studies was performed on children.…”
