Laryngoscopy facilitates successful i-gel insertion by novice doctors: a prospective randomized controlled trial

Abstract

Our results suggest that laryngoscopy facilitates i-gel insertion by novice doctors, as reflected in the rate of successful insertions, higher sealing pressure, and lower subjective difficulty of insertion in anesthetized patients.

Comparison of Pressure Changes by Head and Neck Position between High-Volume Low-Pressure and Taper-Shaped Cuffs: A Randomized Controlled Trial

“…After obtaining written informed consent, 40 patients aged 20 to 75 years who were to undergo general anesthesia in a supine position were randomly assigned (envelope method) to one of two groups: intubation by a tracheal tube with the HVLP cuff (HVLP group, 20 patients) or the taper-shaped cuff (Taper group, 20 patients). Exclusion criteria were morbid obesity defined by a body mass index >35, cervical disease or cervical movement restriction, gastroesophageal reflux, previous upper abdominal surgery, and a recent (within seven days) history of upper respiratory tract infection [ 7 ].…”

Successful airway management with i-gel in the lateral position for a patient combined with sulcus vocalis

“…In contrast, supraglottic airway management, such as use of the i-gel, minimizes the risk of glottis damage, although there is a risk of ventilation failure due to malpositioning in the lateral position. In the present case, we inserted the i-gel under guidance of the McGRATH MAC videolaryngoscope to minimize collisions with the glottis [3], and mechanical ventilation was performed uneventfully as a result.…”

Successful LMA-ProSeal insertion using a tracheal tube introducer in a patient with severe rheumatoid arthritis

“…Our study additionally demonstrated that the tracheal tube introducer can be applied to cases of difficult ProSeal insertion. To facilitate positioning of the tracheal tube introducer into the esophagus, we used the McGRATH videolaryngoscope, which provided a good laryngeal view [3,4]. Use of the videolaryngoscope prevented unnecessary injuries and migration of the introducer.…”
