Gag (medicine)

Medical device used to prevent speech or movement of the mouth

A gag is a device used in medicine to prevent a patient from speaking or moving their mouth. It is often used in anesthesia and surgery to ensure that the airway remains open and to prevent the patient from biting down on medical instruments or their own tongue.

Types of Gags

Gags come in various forms, each designed for specific medical purposes. Some common types include:

• Mouth Gags: These are used to keep the mouth open during dental or oral procedures. They are typically made of metal or plastic and can be adjusted to fit the patient's mouth.

• Bite Blocks: These are used to prevent the patient from biting down during procedures. They are often used in endoscopy and intubation.

• Tongue Depressors: While not a gag in the traditional sense, tongue depressors are used to hold the tongue down to allow for better visibility and access to the throat.

Uses in Medical Procedures

Gags are primarily used in procedures where it is crucial to maintain an open airway and prevent injury to the patient. Some common uses include:

• During general anesthesia, to prevent the patient from biting down on the endotracheal tube.
• In dental surgery, to keep the mouth open and provide access to the teeth and gums.
• In ENT (ear, nose, and throat) procedures, to allow access to the throat and airway.

Use of gag in anaesthetic procedures

Safety and Precautions

While gags are useful tools in medical procedures, they must be used with caution to avoid complications such as:

• Damage to the teeth or gums
• Obstruction of the airway
• Inducing gag reflex

Medical professionals must ensure that the gag is properly fitted and that the patient is monitored throughout the procedure.
