Achieved Gain and Subjective Outcomes for a Wide-Bandwidth Contact Hearing Aid Fitted Using CAM2.

Objectives: The objective of this study was to test the ability to achieve, maintain, and subjectively benefit from extended high-frequency amplification in a real-world use scenario, with a device that restores audibility for frequencies up to 10 kHz.

Design: A total of 78 participants (149 ears) with mild to moderately-severe sensorineural hearing loss completed one of two studies conducted across eight clinical sites. Participants were fitted with a light-driven contact hearing aid (the Earlens system) that directly drives the tympanic membrane, allowing extended high-frequency output and amplification with minimal acoustic feedback.

A prospective, randomized trial of the Ambu AuraGain™ laryngeal mask versus the LMA® protector airway in paralyzed, anesthetized adult men.

Background: We hypothesize that oropharyngeal leak pressures differ between the LMA® Protector™ and the AuraGain™, two novel supraglottic airway devices offering the possibility of intubation.

Methods: Ninety-eight male patients ASAI-II were randomly assigned to the AuraGainTM or ProtectorTM group. Oropharyngeal leak pressure was measured by incrementing cuff volume in 10 mL steps from 10 mL to 40 mL.

Flexible bronchoscopic intubation through the AuraGain™ laryngeal mask versus a slit Guedel tube: a non-inferiority randomized-controlled trial.

Purpose: AuraGain, a novel third-generation laryngeal mask, can facilitate insertion of a gastric tube and provide the potential advantage of intubation. Data are lacking on intubation through the AuraGain laryngeal mask.

Methods: Eighty-eight hip or knee surgery patients were enrolled in this parallel randomized-controlled trial.

Randomized crossover study assessing oropharyngeal leak pressure and fiber optic positioning : Laryngeal Mask Airway Supreme™ versus Laryngeal Tube LTS II™ size 2 in non-paralyzed anesthetized children.

Background: As there are currently no data available comparing the practicability of the laryngeal mask airway (LMA) Supreme™ size 2 versus the laryngeal tube LTS II™ size 2 in children, this trial was conducted to quantify the differences between these two airway devices concerning leak pressure and fiber optic-controlled positioning in non-paralyzed, anesthetized pediatric patients.

Methods: A total of 56 children aged 1-6 years and weighing between 11 and 23 kg were enrolled in the study. Anesthesia was intravenously induced according to local standards using fentanyl and propofol.

Do mask aperture bars of extraglottic airway devices prevent prolapse of epiglottis causing airway obstruction? A randomized crossover trial in anesthetized adult patients.

Study Objective: The study objective is to determine whether extraglottic airway devices (EADs) with or without mask aperture bars (MABs) result in similar anatomical positions in patients undergoing surgery.

Design: Prospective, randomized, crossover comparison of four extraglottic airway devices.

Setting: Operating theatre at a large teaching hospital.
