“…If videolaryngoscopy fails, one should follow the OAA/DAS guidelines, and attempt the use of a supraglottic airway device. Difficult videolaryngoscopy is not uncommon, occurring in over 25% of patients with anticipated difficult airway , but true failure appears to be rare. Difficulty should be anticipated in patients with small mouth opening, altered neck anatomy, and in those with an airway mass or history of neck irradiation, although these predictors are not specific for videolaryngoscopy .…”

“…However, time itself should not be the determining factor in cases where awake tracheal intubation is considered the safest approach, and the alternative, tracheal intubation attempt after induction of anaesthesia in a predicted difficult airway patient may well take longer, and bears the concomitant increased risk of having to revert to emergency front-of-neck access. Mallampati classification score, were common indications for awake tracheal intubation, but evidence suggests that asleep videolaryngoscopy may often overcome this barrier [8]. One may suspect that this advancement has resulted in a reduction in the incidence of awake tracheal intubations performed, but these presumptions have not been supported by evidence to date [9].…”

“…This suggested that VL may not make intubation easier in severe upper airway distortion caused by malignancy or extensive oropharyngeal infection. In a secondary analysis of a data set gathered from a multicentre prospective RCT by Aziz et al (29) comparing GlideScope and Storz C-MAC D-blade VLs in 1,100 patients with anticipated difficult DL, 301 were identified as difficult VL. The multivariate logistic regression analysis showed that four predictors of difficult VL were supine sniffing position, limited mouth opening, planned otolaryngologic or cardiac surgery, and intubation by an attending anesthesiologist.…”

Aim of review:The aim of this article is to convey several hotspot issues regarding the use of videolaryngoscopy (VL) in airway management that anesthesiologists are often concerned. Methods: Recent literature in the past 20 years about the use of VL in the clinical airway management were searched from the Pubmed and Cochrane databases and reviewed, in order to determine the strengths and weakness of VL and conflicting issues regarding the role of VL in airway management. Recent findings: The benefits of VL are most significant in patients with difficult airways, with an improved laryngeal view and an increased success rate of intubation. However, VL cannot give a 100% success rate and there is no specific evaluation system of difficult or failed VL as with direct laryngoscopy. Awake VL-assisted intubation is a useful alternative to awake fiberoptic intubation, but the fiberoptic bronchoscope cannot be discarded and still is gold standard tool of difficult airway management. There are several differenttype VLs available and their efficacies may be different between devices due to various designs and shapes. Due to the limited number of comparative studies, however, there is inconclusive evidence to recommend which VL design is more advantageous in various clinical situations. A Macintosh-type VL allows residents to learn laryngoscopy and intubation more quickly and effectively. Given that VL has tremendous advantages, it should be used as the first-line device for all tracheal intubations. Summary: The introduction of VL has resulted in a dramatic transformation of clinical airway management and is seen as the evolutionary step in intubation technology. There are considerable disagreements over the role of VL in airway management and the need of more investigation, but VL continues to get popularity both inside and outside the operating room. With increasing use of VL in airway management, experience and skill will undoubtedly increase, and the evidence will suggest that the attempt numbers and complications of intubations may be decreased, and patient safety can be improved.

Predictors of difficult videolaryngoscopy with GlideScope® or C-MAC® with D-blade: secondary analysis from a large comparative videolaryngoscopy trial

Abstract: This secondary analysis of an existing data set indicates four covariates associated with difficult acute-angle videolaryngoscopy, of which patient position and provider level are modifiable.
