BACKGROUND AND AIMS: The application of cricoid pressure (CP) for rapid sequence induction is questioned on two grounds: its effectiveness in clinical settings and its impact on the laryngeal view. The main reason cited for its ineffectiveness is the lack of knowledge and training in its correct application. This study assessed, the performance of anesthetists in applying effective CP in a clinical setting. MATERIAL AND METHODS: Eighty-five ASA I/II adult patients posted for elective surgery requiring oral endotracheal intubation with nasogastric tube (NGT) placement participated in the study...

BACKGROUND: Previous studies have reported that the ramped position provides a better laryngoscopic view, reduces tracheal intubation time, and increases the success rate of endotracheal intubation. However, the patient's head height changes while in the ramped position, which in turn changes the relative positions of the patient and intubator. Thus, making these changes may affect the efficiency of tracheal intubation; however, few studies have addressed this problem. This study analyzed intubation time and conditions during tracheal intubation using videolaryngoscope in the ramped position...

OBJECTIVE: Intubation is a highly aerosol-generating procedure. Recent airway management guidelines advocate the use of appropriate personal protective equipment, videolaryngoscope, and "intubation box" while intubating a suspected or infected coronavirus patient. We undertook a study to compare C-MAC videolaryngoscope with McGrath videolaryngoscope for tracheal intubation using an intubation box by donned anaesthesiologists. METHODS: The patients were randomly allocated to 2 groups by computer-generated random numbers, depending upon the videolaryngoscope used...

Rabbits are being increasingly used as companion animals, and in research; thus, the need for proper veterinary care for rabbits has increased. Surgical access is more challenging in rabbits under inhalation anesthesia compared to other animals, such as dogs and cats. Rabbits have a very narrow and deep oral cavity, large incisors, and a large tongue. Moreover, their temporomandibular joint has limited mobility, making it more difficult to approach the larynx. Various methods have been proposed to overcome this difficulty...

BACKGROUND: The head-elevated laryngoscopy position has been described to be optimal for intubation, particularly in obese patients and those with anticipated difficult airways. Horizontal alignment of the external auditory meatus and sternal notch (AM-S) can be used as endpoints for optimal positioning. Thus, we aligned the head-elevated position with the AM-S in the horizontal plane and evaluated its effect on laryngeal visualization and ease of intubation using a McGrath MAC videolaryngoscope in patients with a simulated difficult airway...

Intubation is required to maintain anesthesia in patients who are planned to undergo surgery under general anesthesia. One of the most important steps for successful intubation is to position head and neck appropriately. Sniffing position, head extension position, and neutral head position are the most known and used head and neck positions. The aim of this study is to examine the effect of head position on glottic visualization with McGrath MAC® video laryngoscope (VL) and intubation success in obese patients who are scheduled for surgery...

PURPOSE: Intubation and ventilation cannot be performed in cases of parapharyngeal space tumors as the enlargement of the upper airway leads to the obstruction and hindrance of the intubation procedure. However, there is limited literature on anesthetic management, including the airway, in this disease. Herein, we report a successful case of awake intubation in a patient with parapharyngeal space tumor. CASE PRESENTATION: A 64-year-old man with a history of giant parapharyngeal space tumor was scheduled for bilateral endoscopic sinus surgery and nasal septoplasty...

The use of both a video laryngoscope and a video intubation stylet, compared with the use of a direct laryngoscope, is not only easier to learn but also associated with a higher success rate in performing endotracheal intubation for novice users. However, data comparing the two video devices used by novice personnel are rarely found in literature. Nondelayed intubation is an important condition to determine the prognosis in critically ill patients; hence, exploring intubation performance in various situations is of clinical significance...

INTRODUCTION: During the coronavirus disease 2019 (COVID-19) pandemic, multiple guidelines have recommended videolaryngoscope (VL) for tracheal intubation. However, there is no evidence that VL reduces time to tracheal intubation, and this is important for COVID-19 patients with respiratory failure. METHODS: To simulate intubation of COVID-19 patients, we randomly assigned 28 elective surgical patients to be intubated with either McGrath™ MAC VL or direct laryngoscope (DL) by specialist anaesthetists who donned 3M™ Jupiter™ powered air-purifying respirators (PAPR) and N95 masks...
