Randomized Controlled Trial
Incidence of gastric insufflation at high compared with low laryngeal mask cuff pressure in a first-generation laryngeal mask detected by ultrasound: A randomised controlled cross-over trial.
The success of ventilation with a laryngeal mask depends crucially on the seal between the mask and the periglottic tissue. Increasing the laryngeal mask's cuff volume is known to reduce oral air leakage but may lead to gastric insufflation. ⋯ The study was registered in the German Clinical Trials Register (DRKS00010583) https://www.drks.de.
