Laryngeal Masks for Bariatric Surgery

Phase 3

• Conditions: Morbid Obesity

• Registration Number: NCT01724970
• Lead Sponsor: University of Padova

Brief Summary

Obese people pose specific problems as far as the management of airway during surgery. The study aims to compare efficacy and safety of two LMA devices.

Detailed Description

The study will investigate two types of LMA devices endowed of different constructive features. The two devices share common features as far as providing access to the stomach and reducing morbidity of the upper airway. The two device differ in regard to ease of insertion and sealing of the airway and these features are particularly important in the obese patient.
