Purpose: This study investigated dimension changes of various nasopharyngeal airways, including a novel self-supporting device, after saline submersion at body temperature to simulate in-vivo use. Dimension changes over time may reduce efficacy during long-term use and require sizing adjustments or limits on duration of use.
Materials And Methods: Cuffless Covidien endotracheal tubes, pediatric Rusch fixed flange polyvinyl chloride nasal airway tubes, pediatric Rusch Robertazzi style Mediprene nasal airway tubes, and novel silicone elastomer self-supporting nasopharyngeal airways were fully submerged in 0.
Hearing Outcomes of a New Cartilage Conduction Device vs Bone Conduction Devices.
Otolaryngol Head Neck Surg
April 2023
Article Synopsis
- A clinical trial was conducted to compare the audiometric performance of a new cartilage conduction device (CCD) against traditional bone conduction devices (BCDs) in individuals with congenital hearing issues.
- The results revealed that while both devices significantly improved hearing, BCDs generally provided better pure tone averages, particularly in high-frequency sounds, with average scores of 27 dB for BCDs compared to 32 dB for CCDs.
- Speech recognition scores were mostly similar between the two devices, but BCDs showed a statistically significant advantage in a specific noise condition (+5 dB SNR), indicating they may perform slightly better in some listening situations.
Background: At the patient level, optimizing risk factors before surgery is a proven approach to improve patient outcomes after hernia repair. However, nearly 25% of patients are not adequately optimized before surgery. It is currently unknown how surgeon-level adherence to preoperative optimization impacts postoperative outcomes.
