Comparison of King Vision video laryngoscope and Macintosh laryngoscope: a prospective randomized controlled clinical trial

Hemodynamic changes during orotracheal intubation using Airtraq video laryngoscope and direct laryngoscope: A randomized comparative study

“…18 Similar finding for intubation time was observed in many other studies using KingVision video laryngoscope, Airtraq and Glidescope when all these were compared with Macintosh laryngoscope. 5,12,19 Unlike these studies, Castillo-Monzón CG et al and Dhonneur G et al found shorter intubation time with Airtraq when compared with Macintosh laryngoscope. 10,20 But, many researchers have observed significantly longer time for intubation using video laryngoscope mostly Glidescope when compared with Macintosh laryngoscope.…”

The importance of videolaryngoscopy in maxillofacial practice associated with restricted mouth opening in traumatized patients

“…The introduction of new tools in clinical practice for intubation is necessary in order to overcome the difficulties that may appear during an intubation of patients with difficult airways (VAD) (Ciccozzi et al, 2013, Kilicaslan et al, 2014, Cunha Andrade et al, 2018. Among the situations that require more caution from the professional and that can characterize a difficult intubation, are the removal distance (<12.5cm), hyoid distance (<6cm), Mallampati classification (3 or 4), reduced mandibular protrusion, neck circumference (> 40cm) , obstructive sleep apnea syndrome, macroglossia, mandibular or dental abnormalities, history of snoring, restricted mouth opening (interincisive distance), among others (Erdivanli et al, 2018, Cunha Andrade et al, 2018, Selvi et al, 2020, Apfelbaum et al, 2013, Detsky et al, 2019, Nausheen et al, 2019.…”

“…The patient's mouth opening must be at least 2 cm, and this means that there is enough space to position the blade between the upper and lower teeth. The presence of trismus and problems in the temporomandibular joint can reduce this distance and, consequently, increase the difficulty of visualization and manipulation of important anatomical structures, which can prevent the success of intubation (Erdivanli et al, 2018, Detsky et al, 2019, Turcio et al, 2017, Jungbauer et al, 2009.…”

“…Given this scenario, when conventional laryngoscopes are not satisfactory, videolaryngoscopy is one of the tools that can be used to facilitate intubation in the event of a difficult airway (Ciccozzi et al, 2013, Erdivanli et al, 2018, Kilicaslan et al, 2014, Apfelbaum et al, 2013, Jungbauer et al, 2009, Aziz et al, 2012 and through it, it is possible to obtain a better view of the laryngeal structures, with faster intubations and less need for optimization maneuvers through the use of video laryngoscopes (Ciccozzi et al, 2013, Kilicaslan et al, 2014, Jungbauer et al, 2009, Berkow et al, 2018, Niforopoulou et al, 2010. However, there are still controversies in the literature (Erdivanli et al, 2018& Aziz et al, 2012 whether videolaryngoscopy can increase the success of intubation particularly in the predicted difficult airway, as some studies have limited interpretive value (Aziz et al, 2012& Berkow et al, 2018.…”

“…Video laryngoscopes usually have a light source at the tip of their blade and a camera that projects the image in real time to a portable video system, thus, another advantage that can be mentioned, is that they allow to abandon the need for alignment of the oral, pharyngeal and tracheal axes to receive a direct view of the glottis, which facilitates the intubation of patients with pathology or immobilization of the cervical spine (Ciccozzi et al, 2013, Erdivanli et al, 2018, Kilicaslan et al, 2014, Jungbauer et al, 2009, Aziz et al, 2012, Berkow et al, 2018, Niforopoulou et al, 2010.…”
