Is Trachlight really better than the Bonfils fibrescope?
No full textThe recent article of J.-H. Sui et al.1 comparing the
transillumination-assisted orotracheal intubation using the
Bonfils fibrescope (Karl Storz, Tuttlingen, Germany) and the
lightwand [Trachlight (Laerdal Medical Co., Wappingers Falls,
NY, USA)] was of great interest. However, although they have
provided valuable information, there are several aspects of this
study that have to be clarified. We agree with the authors that
this is the first detailed report of the transillumination method of
modifying the use of the Bonfils fibrescope, but the results of this
study should be extrapolated to the clinical settings with
caution.As well reported in literature,2–7 the best intubation techniques
with Bonfils fibrescope (paraglossic or retromolar)
involves a continuous endoscopic vision, beginning from introduction
into the oral cavity to the visualisation of the vocal cords.
Because of its fixed curvature and rigid metallic structure, it
could be very dangerous using this device with a blind transoral
technique, as proved by the complications that occurred in
this study (sore throat 14% and hoarseness 8.7%)1 and the
absence of these when using it correctly.3,5,7 Furthermore, the
brightness of its light source is poorer than that of Trachlight, as
well reported by the authors.1 Moreover, the longer intubation
times with Bonfils fibrescope compared with Trachlight would
be due to an improper use of the device; a first blind oral introduction
was followed by an endoscopic view of the operator
through the eyepiece to localise the glottis before tracheal tube’s
insertion.7,8 We are conscious of the disadvantages of an endoscopic
view due to secretions, blood or fogging,7 but we think
that it is the ‘gold standard’ for Bonfils fibrescope. In 2006, Biro
et al.9 proved that aptitude for endoscopic viewing, more than
experience and skill in standard laryngoscopy, could improve
the learning curve of rigid fibrescope utilisation, so the use of
this device is not intuitive and needs a greater learning curve
when compared with blind devices as Trachlight.5–7 The Bonfils
fibrescope was previously compared with the intubating laryngeal
mask airway10 after conventional laryngoscopy failed. The
results of this study found a comparable success rate, but a
significantly shorter time to intubation and a decreased postanaesthesia
airway morbidity was noted in the Bonfils group.We
believe that the possibility to advance the endotracheal tube
under direct visualisation avoids some of the complications associated
with intubation using blind devices

No full textThe Bonfils fiberscope: a clinical evaluation of its learning curve and efficacy in difficult airway management.
No full textBACKGROUND: This study evaluated the use of the Bonfils fiberscope by analyzing its learning curve, efficacy and safety during airway management. METHODS: This was a prospective observational study where five anesthetists, with differing levels of experience, were asked to use the Bonfils rigid fiberscope (Karl Storz) for a six-month period. They used the scope when performing endotracheal intubations in patients undergoing general anesthesia. The patients were excluded if various clinical indicators predicted that they might be difficult to intubate. The patient's head was kept in the neutral position to simulate the intubation of a trauma patient. Direct laryngoscopy with a Macintosh blade was performed to assign a Cormack and Lehane grade prior to attempting laryngoscopy with the Bonfils fiberscope. After intubating the patient with the Bonfils fiberscope, intubation time and any complications or failures noted after the procedure were recorded. RESULTS: The study included 216 patients, three of which were failed intubations. No complications occurred during the study period. The median intubation time was 21.43 s. The learning curve improved significantly after 20 intubations (P<0.05) and was affected by the operator's experience and aptitude with endoscopic viewing. Seventeen patients were deemed to have "unpredicted" difficult airways: 15 subjects with a Cormack grade 3 (6.9%) and two subjects with a Cormack 4 (0.9%). Median time to intubation in subjects with a Cormack <3 was 16 s (95% CI=10-29 s), and in subjects with a Cormack ≥3, it was 15 s (CI 95%=15-18 s) with P=0.703. CONCLUSION:The Bonfils fiberscope is an efficient, easy to use and safe device for endotracheal intubation
Rigid fibrescope Bonfils: use in simulated difficult airway by novices
No full textAbstract Background The Bonfils intubation fibrescope is a promising alternative device for securing the airway. We examined the success rate of intubation and the ease of use in standardized simulated difficult airway scenarios by physicians. We compared the Bonfils to a classical laryngoscope with Macintosh blade. Methods 30 physicians untrained in the use of rigid fibrescopes but experienced in airway management performed endotracheal intubation in an airway manikin (SimMan, Laerdal, Kent, UK) with three different airway conditions. We evaluated the success rate using the Bonfils (Karl Storz, Tuttlingen, Germany) or the Macintosh laryngoscope, the time needed for securing the airway, and subjective rating of both techniques. Results In normal airway all intubations were successful using laryngoscope (100%) vs. 82% using the Bonfils (p Conclusion The Bonfils can be successfully used by physicians unfamiliar with this technique in an airway manikin. The airway could be secured with at least the same success rate as using a Macintosh laryngoscope in difficult airway scenarios. Use of the Bonfils did not delay intubation in the presence of a difficult airway. These results indicate that intensive special training is advised to use the Bonfils effectively in airway management.</p

Bonfils intubation fibrescope : use in simulation-based intubation training for medical students in comparison to MacIntosh laryngoscope
No full textBACKGROUND:
A variety of instruments are used to perform airway management by tracheal intubation. In this study, we compared the MacIntosh balde (MB) laryngoscope with the Bonfils intubation fibrescope as intubation techniques. The aim of this study was to identify the technique (MB or Bonfils) that would allow students in their last year of medical school to perform tracheal intubation faster and with a higher success probability. Data were collected from 150 participants using an airway simulator [‘Laerdal Airway Management Trainer’ (Laerdal Medical AS, Stavanger, Norway)]. The participants were randomly assigned to a sequence of techniques to use. Four consecutive intubation ‘trials’ were performed with each technique. These trials were evaluated for differences in the following categories: the ‘time to successful ventilation‘, ‘success probability’ within 90 s,’time to visualisation’ of the vocal cords (glottis), and ‘quality of visualisation’ according to the Cormack and Lehane score (C&L, grade 1–4). The primary endpoint was the ‘time to successful ventilation‘in the fourth and final trial.
RESULTS:
There was no statistically significant difference in the ‘time to successful ventilation’ between the two techniques in trial 4 (‘time to successful ventilation’: median: MB: 16 s, Bonfils: 14 s, p = 0.244). However, the ‘success probability’ within 90 s was higher when using a Macintosh blade than when using a Bonfils (95 vs. 87 %). The glottis could be better visualised when using a Bonfils (C&L score of 1 (best view): MB: 41 %, Bonfils: 93 %), but visualisation was achieved more rapidly when using a Macintosh blade (median: ‘time to visualisation’: MB: 6 s, Bonfils: 8 s, p = 0.003).
CONCLUSIONS:
The time to ventilation using the MacIntosh blade and Bonfils mainly did to differ, however success probabilities and time to visualisation primary favoured the MacIntosh blade as intubation technique, although the Bonfils seem to have a steeper learning curve. The Bonfils is still a promising intubation technique and might be easier to learn as the MB, at least in a manikin
Hemodynamic responses to tracheal intubation with Bonfils compared to C-MAC videolaryngoscope: a randomized trial
No full textAbstract Background Direct laryngoscopy (DL) produce tachycardia and hypertension that could be fatal in a patient with a brain injury. Bonfils fiberscope and C-MAC videolaryngoscope are associated with little hemodynamic instability compared to DL. Scientific evidence comparing these two alternatives does not exist. We conducted this study to determine the hemodynamic effects of Bonfils compared to C-MAC in patients undergoing elective surgery. Methods Fifty (50) patients listed for elective surgery were randomly assigned to endotracheal intubation with Bonfils or C-MAC. After a standardized induction, intubation was done via the retromolar approach (Bonfils group) or via videolaryngoscopy (C-MAC group). A research assistant, who was not blinded to the intervention, recorded heart rate (HR) and arterial blood pressure (systolic, diastolic and mean arterial blood pressure [MAP]) at induction and at every minute during the 5 min post intubation. The primary outcome was the hemodynamic response to intubation, as verified every minute for the first 5 min compared to baseline value. Results After randomization, the two groups were comparable except for ASA I/II ratio which was slightly higher in the C-MAC group (p = 0.046). Heart rate (p = 0.40) and MAP (p = 0.30) were comparable between the two groups within 5 min post intubation. Intubation time was shorter with C-MAC than with Bonfils (30 ± 2 s vs 38 ± 2 s; p = 0.02). Conclusion Hemodynamic responses to tracheal intubation using the Bonfils fiberscope is comparable to the C-MAC videolaryngoscope among patients scheduled for an elective surgery. In light of these findings, using either technique appears to be a reasonable course of action. Trial registration ISRCTN #34923, retrospectively registered, 26/03/2018
