“…An essential consideration for mask ventilation safety is whether sufficient ventilation has been achieved or not [2]. Nonmedical personnel often find it difficult to evaluate and differentiate sufficient or difficult mask ventilation [3]. Here, we conducted a survey on the subjective difficulty of evaluating the quality of adult and infant mask ventilation by non-medical personnel from various viewpoints.…”

“…from four upward, headsiderd, and lateral-horizontal b). The difficulty of evaluating the quality of ventilation by the same the four viewpoints was evaluated on a visual analog scale (VAS), which ranged from 0 (extremely easy) to 100 (extremely difficult) [3,4]. The order of evaluation was using random number table.…”

“…Cavus et al (51) evaluated the C-MAC videolaryngoscopy during prehospital emergency intubation performed by physicians and found a failure rate of 7.5% . The common causes of failed videolaryngoscopy include a limited mouth opening, a large tongue, a tumor in the oropharynx or blurred vision by fogging, secretions, blood, or vomitus, cricoid pressure, etc (43,(49)(50)(51)(52)(53)(54). b) Because videolaryngoscopes are larger than flexible fibrescope, they exert more tractions on the upper airway, and may therefore induce gagging and uncomfort in awake patients, independent of the type of the local anesthetic used (45).…”

Aim of review:The aim of this article is to review the recent literatures regarding videolaryngoscopes, compare performance of videolaryngoscopy versus direct laryngoscopy, discuss the role of videolaryngoscopy in clinical airway management and provide the measures that can improve the performance of videolaryngoscopy and decrease complications associated with videolaryngoscopy. Methods: The literatures about the use of videolaryngoscopes in the clinical airway management, published in the past decades, were searched from the Pubmed and Cochrane databases and reviewed, in order to determine their performance, and identify their limitations and find appropriate alternate techniques to overcome their shortcomings and failures. Recent findings: Videolaryngoscopes are promising intubation devices, which are easy to use, and the skills involved are easy to obtain by either novices or experienced intubators. In the current practice, videolaryngoscopes are commonly used as main devices of predicted difficult airways and as rescue tools of difficult or failed direct laryngoscopy. For patients with difficult airways, videolaryngoscopy can provide an improved laryngeal visualization and achieve a higher intubation success rate compared with direct laryngoscopy. Moreover, videolaryngoscopy has the potential to increase patient safety by facilitating learning, teaching, and success of tracheal intubation. Despite the very good laryngeal visualization, the insertion and advancement of the tracheal tube with videolaryngoscopy may occasionally fail, and the airway injuries associated with videolaryngoscopy can occur. Summary: The introduction of videolaryngoscopy has resulted in a dramatic transformation of clinical airway management and is seen as the evolutionary step in intubation technology. There are several different types of videolaryngoscopes available. Each device's features may offer advantages or disadvantages, depending on the situation the anesthetist has to deal with. To get the best out of videolaryngoscopy, all anesthetists must be trained in the use of videolaryngoscopes and such devices should be available in all sites where tracheal intubation is performed.

“…Reported difficulties include limited mouth opening, a large tongue, a tumor in the oropharynx, laryngospasm, and blurred vision [22]. Recent studies [25,26] have added several other risk factors-suboptimal head and neck position, cricoid pressure, inexperience, and patients undergoing otolaryngologic or cardiac surgery.…”

“…Videolaryngoscopes have roles in patients with difficult airways, but they may fail [21,25,26] and may not be able to reduce the incidence of anesthesia-related death [3]. Reported difficulties include limited mouth opening, a large tongue, a tumor in the oropharynx, laryngospasm, and blurred vision [22].…”
