Summary
Brief summary
The laryngeal tube suction II (LTS-II) is a recent version of supraglottic airway devices allowing gastric drainage. In this prospective, randomized study we compared insertion and ventilation of disposable LTS-II with reusable type for airway management under conditions with elevated intra abdominal pressure induced by capnoperitoneum.
