BACKGROUND In regards to peri-anesthetic morbidity considerations, morbidly obese patients often have full stomach for extended periods secondary to delayed gastric emptying. Additionally, they may have difficulty lying supine because of multiple reasons. STUDY OBJECTIVES The purpose of the study was to compare endotracheal intubation of morbidly obese patients placed in semi-erect position w...

tracheal intubation is the most common factor related to serious airway complications during anesthesia [1]. Difficult tracheal intubation is defined as insertion of the endo-tracheal tube using direct laryngoscopy that requires more than two attempts lasting more than 10 min each or that requires an alternative technique [2]. The difficult airway involves interactions among patient factors, th...

O ver the past decade, video laryngoscopy has profoundly transformed airway management. Its recent inclusion in the American Society of Anesthesiologists Difficult Airway Algorithm validates its adoption. Not surprisingly, the commercial success of the GlideScope (Verathon Medical), the first mass-produced video laryngoscope (VL), has inspired many other companies to enter the airway management...

UNLABELLED BACKGROUND The purpose of our study was to organize the literature regarding the efficacy of modern videolaryngoscopes in oral endotracheal intubation, then perform a quality assessment according to recommended external criteria and make recommendations for use. METHODS Inclusion criteria included devices with recent studies of human subjects. A total of 980 articles were return...

We report the first case of near serious lingual nerve injury in an 80-y-old female caused by the Rigid GlideScope Stylet. This complication was discovered during oral surgery and may have been missed if the site of surgery was not oral cavity.

We thank Dr. Dupanovic for his interest in our study. As mentioned in our manuscript,1 we chose the two stylet angles to be studied based on the most common angulations used by anesthesiologists in our local practice. The distal 60° angulation used at our centre and in the study was heavily influenced by an expert in airway management who described using a stylet shape that closely approximates...
