Use of a Combined Laryngo-Bronchoscopy Approach in Difficult Airways Management: A Pilot Simulation Study
There are several airway devices available for difficult tracheal intubation (DTI) management, but the failure rate remains high. The use of laryngoscopy to facilitate the fibreoptic-bronchoscope intubation (CLBI) has been increasingly reported in DTI situations, but it has not been formally studied...

Zusammenfassung: | There are several airway devices available for difficult tracheal intubation (DTI) management, but the failure rate remains high. The use of laryngoscopy to facilitate the fibreoptic-bronchoscope intubation (CLBI) has been increasingly reported in DTI situations, but it has not been formally studied yet.
We designed a single-centre simulation study on DTI (neck rigidity and tongue oedema) comparing three techniques: direct laryngoscopy (DL), video-laryngoscopy (VLS) and CLBI. Eighteen anaesthesiologists naïve to VLS/CLBI approaches, participated in the study. The primary outcome was the intubation rate at the first attempt. Secondary outcomes were an overall time-to-intubate (TTI) and time-to-ventilate (TTV), success at the second and third attempt and ease of intubation as evaluated by a subjective 5-point Likert scale.
The CLBI technique had a higher success rate at the first attempt than DL (66% vs 22%, p=0.007), while VLS did not (44%, p=0.16). A trend towards higher success at the third attempt was found for both VLS and CLBI vs DL (p=0.07 and p=0.06, respectively). The VLS had a shorter overall TTV than DL (88±60 vs 121±59 sec, respectively, p=0.04) and a trend towards a shorter TTI (81±61 vs 116±64 sec, respectively, p=0.06). The CLBI approach showed a non-significantly lower TTI/TTV as compared to DL (p=0.10 and p=0.16, respectively). Anaesthesiologists judged that the intubation with VLS (3.7±1.0) and CLBI (3.8±1.0) was easier than with DL (1.7±0.8, both p |
