Airway Clinical Trial - Multicenter Study of the Protector Laryngeal Mask

Status Completed

Clinical Trial Summary

The study was designed to evaluate the success rate, time of insertion, sealing efficacy and security of the Protector Laryngeal Mask, a new second generation disposable supraglottic airway device, in patients undergoing elective surgery.

Clinical Trial Description

Laryngeal masks (LM) and supraglottic devices (SGD), in all their different forms, have become an authentic innovation in airway management especially in day surgery.

LMA Protector (Teleflex Medical, Athlone, Ireland) is a new disposable SGD currently available for anaesthetic practice. It is made of silicone (with no latex in its composition) and shares some of the characteristics of the second generation SGDs (as the presence of a gastric access channel); however, it has an additional drainage channel, both channels terminate distally in a camera behind the mask cuff. The presence of two drainage channels ("male" and "female") increases the patient safety against regurgitation, both of distal gastric content and secretions located in the oropharyngeal region. The gastric access channel called "female" also allows the insertion of a nasogastric tube if required. These drainage channels are useful for diagnosing the correct position of the mask, since the observation of leaks or gas through it can help diagnose a displacement the mask.

LMA Protector is designed with a preformed anatomic curve, and the airway conduct has an elliptical cross section, which ends distally in the mask. This design follows the anatomy of the human airway, which facilitates the insertion of the device. The softness of the mask material allows easy insertion.

Doubts regarding the transmission of infectious diseases with reusable devices makes disposable devices such as LMA Protector, one of the most interesting devices for use in anaesthetic procedures that are usually performed with SGD.

Its characteristics in the design, composition by a smooth and atraumatic material, the presence of two gastric drainage accesses, with potential improved patient safety and its characteristic of being disposable suggests a significant expansion of its use in the coming years .

In contrast to other SGDs that have been evaluated extensively, to date there are no large clinical studies showing its suitably and performance in a daily clinical scenario. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
