Brief Summary

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

The goal of this randomized clinical trial is to compare two different orotracheal tubes in patients which require orotracheal intubation for general anesthesia. The main questions it aims to answer are:

* To assess the presence of laryngeal injury
* To evaluate the consequences in voice quality
* To ask for the presence of symptoms as sore throat, hoarseness, and cough

Participants will be randomly assigned into two groups, one will use conventional endotracheal tube and the other will use Triglotix® endotracheal tube.

Detailed Description

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

Endotracheal intubation is necessary in some patients undergoing surgical procedures and patients requiring mechanical ventilation in the intensive care unit. However, endotracheal intubation is associated with known complications. In post-surgical patients subjected to orotracheal intubation, the incidence of dysphagia, sore throat, hoarseness and cough is 43%,38%27%,32% respectivelly. These figures increase in cases of prolonged intubation, such as those in intensive care units, where reported rates are 76% for sore throat, 63% for hoarseness and 49% for dysphagia. No significant endotracheal tube design improvements have been developed over the past few decades addressing these issues.

The present study aims to compare the incidence of laryngeal injuries, and related symptoms as sore throat, hoarseness, swallowing problems, bucking and coughing between two defined sample populations: those utilizing a conventional endotracheal tube (ETT-C) and those employing the new Triglotix® endotracheal tube (ETT-T) in patients undergoing elective surgery requiring general anesthesia and mechanical ventilation.

ETT-T

Endotracheal tube Triglotix®

Group Type EXPERIMENTAL

Triglotix®

Intervention Type DEVICE

The Triglotix® has a biocompatible self-expanding viscoelastic cuff that is located in the supraglottic, glottic and subglottic space. This cuff separates the endotracheal tube from the laryngeal vestibule in the supraglottic space and the vocal cords avoiding direct tissue damage from the plastic components of the tube. The viscoelastic cuff self-expands after the endotracheal tube is in adequate position in the airway. Then it adapts progressively and gradually to the shape of structures it comes in contact with, applying minimal pressure to the surrounding tissue. The ETT-T also has two wire reinforced segments: the first is located outside the mouth to prevent deformation related with kinking, while the second segment is positioned distally along the larynx. The primary purpose of this design is to mitigate torsional, rotational and lateralization forces that the tube may encounter while the patient is intubated.
