Endotracheal Tube (ETT) 180: Stylet-loaded Endotracheal Tube Rotation Before Insertion
What this study is about
The main objective of the proposed study is to clarify whether rotating a stylet-loaded endotracheal tube (ETT) 180 degrees prior to intubation will decrease the incidence of postoperative throat soreness, when compared to standard technique used in the usual treatment.

The main objective of the proposed study is to clarify whether rotating a stylet-loaded endotracheal tube (ETT) 180 degrees prior to intubation will decrease the incidence of postoperative throat soreness, when compared to standard technique used in Standard of Care.
Interventions
DEVICE
Direct Laryngoscope (DL)
DL allows visualization of the larynx. It is used during general anesthesia, for surgical procedures of the larynx, and during resuscitation.
DEVICE
Video laryngoscope (VL)
VL facilitates intubation while allowing clinicians to share and record real-time high-resolution images and video.
PROCEDURE
Endotracheal Tube (ETT) 180
A novel maneuver has been described to decrease the insult from stylet named Endotracheal Tube (ETT) 180; a clockwise rotation of the stylet-loaded Endotracheal Tube (ETT) 180 degrees on its axis right after the tip of Endotracheal Tube (ETT) passes the patient's vocal cords (glottis) before fully inserting the Endotracheal Tube (ETT) and then, pulling the stylet out. This maneuverer allows the stylet to match the posterior angulation of the trachea.
Primary outcome measures
Incidence of postoperative sore throat
Time frame: 24 hours after Endotracheal Tube (ETT) placement
To assess the differences in incidence of postoperative sore throat after intubation between the conventional technique and ETT 180 rotation of the ETT.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
