Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Investigators study the performance of both masks, Proseal Laryngeal Mask Airway (PLMA) and I-gel, as temporary ventilatory supraglottic airway devices (SGDs) before tracheal intubation in morbidly obese patients. Data are lacking in such population of patients

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The available data regarding SGDs in morbidly obese patients have focused mainly on PLMA. In general, SGDs have been successfully used as temporary ventilatory devices before laryngoscope-guided tracheal intubation, conduits for endotracheal tube insertion, and primary airway devices during surgery. Second-generation SGDs are preferred for both rescue airway and routine use, compared with first-generation, non-gastric access devices. Data on comparison PLMA vs. I-gel in morbidly obese patient are lacking.

The PLMA is a second generation gastric access SGD. PLMA is composed of an airway tube that connects to a mask which, after insertion through the patient's mouth and inflation of cuff, forms an airtight seal on top the glottis allowing a secure airway to be managed by a health care provider. PLMA can be autoclaved and reused many times. I-gel is a new type of single use, second generation, gastric access SGD and doesn't have an inflatable cuff. Because of its thermoplastic elastomer structure, it exactly adapts to the supraglottic tissue by binding with body temperature, thus minimising air leakage.

The aim of this study is to compare PLMA and I-gel regarding insertion success rate, the time of insertion, gastric access tube positioning, oropharyngeal leak pressure, assessment of position by fiberoptic, ventilatory parameters and hemodynamic, and complications for each device placed before tracheal intubation in morbidly obese patients.

This study is conducted at University Medical Hospital of Padova, with approval from Hospital research Ethical Committee and written informed consents from patients,. Patients are randomly allocated into 2 equal groups, according to the inclusion and exclusion criteria.

PLMA (n=35) in which PLMA is used for ventilation. I-gel (n=35) in which I-gel is used for ventilation.
