A chip camera at the tip of the endoscope – this has now replaced the coaxial optic fibers of older scopes that were prone to damage and consequent loss of picture quality Air/water channel to clean the lens using the water and air channel for drying the lens itself and to insufflate the esophagus and the stomach during the operation to ...
After the procedure, the patient will be observed and monitored by a qualified individual in the endoscopy room or a recovery area until a significant portion of the medication has worn off. Occasionally, the patient is left with a mild sore throat, which may respond to saline gargles or chamomile tea. It may last for weeks or not happen at all.
Anatomical parts seen during laryngoscopy. Direct laryngoscopy is carried out (usually) with the patient lying on their back; the laryngoscope is inserted into the mouth on the right side and flipped to the left to trap and move the tongue out of the line of sight, and, depending on the type of blade used, inserted either anterior or posterior to the epiglottis and then lifted with an upwards ...
The score is assessed by asking the patient, in a sitting posture, to open their mouth and to protrude the tongue as much as possible. [1] The anatomy of the oral cavity is visualized; specifically, the assessor notes whether the base of the uvula, faucial pillars (the arches in front of and behind the tonsils) and soft palate are visible.
Before inserting the probe, mild to moderate sedation is induced in the patient to ease the discomfort and to decrease the gag reflex. Usually a local anesthetic spray (e.g., lidocaine, benzocaine, xylocaine) is used for the back of the throat or as a jelly/lubricant anesthetic for the esophagus. Sedation and anesthesia are required to make the ...

A laryngeal mask is composed of an airway tube that connects to an elliptical mask with a cuff which is inserted through the patient's mouth, down the windpipe, and once deployed forms an airtight seal on top the glottis (unlike tracheal tubes which pass through the glottis) allowing a secure airway to be managed by a health care provider.
An oropharyngeal airway (OPA) is a rigid tube that is inserted into the mouth through the oropharynx and placed above the tongue to move it away from the back of the throat. [2] [4] They are more commonly used than nasopharyngeal airways (NPAs). [4] OPAs should only be used in profoundly unresponsive or unconscious patients without a gag reflex.
