The endoscope is a long thin flexible tube equipped with a miniature video camera and fibre optic lighting at its tip. It is inserted through the mouth and advanced inside slowly guided by the camera image.
Images are seen on a monitor and are recorded for later study and confirmation if required.
Appropriate patient preparation, skilled assistants, and monitoring of the patient’s well-being before, during and after the procedure ensures that endoscopic examinations can be carried out safely.
The maintenance of airway and cardio-respiratory equilibrium during sedated endoscopic examination requires dedicated medical personnel.
Recovery is in two stages.
- The first is complete when the patient is awake and the blood pressure is stable. This may require additional intravenous fluid therapy.
- During the second stage the patient regains all their usual bodily functions, however, may still be drowsy.
