Precautions for patients with nasopharyngeal carcinoma undergoing electronic endoscopy

Because the nasopharynx is located at the back of the nasal cavity and cannot be seen directly with the eyes, doctors often need to have certain clinical experience and examination tools to make a diagnosis of nasopharyngeal carcinoma. For example, electronic endoscopes are one of the tools commonly used by doctors.

Clinical electronic endoscopy usually uses a long fiberoptic soft endoscope, which is inserted into the back of the enemy through the nasal cavity or oral cavity to observe and photograph the tumor at close range. Before the examination, the patient generally does not need special preparation, but needs to be aware of some precautions.

1) Patients with fever, high blood pressure, bleeding disorders, or menstruation should inform the doctor during the examination or postpone the examination;

2) During the examination, the patient should bring relevant laboratory test results, CT or MRI films, etc. for the doctor's reference;

3) Before the examination, the nurse sprays 2% ephedrine into the bilateral nasal cavities to shrink the inferior turbinate, and sprays 1% to 2% cocaine into the bilateral nasal cavities and inhales it into the nasopharynx for surface anesthesia;

4) During the examination, the patient lies supinely on the examination bed in the operating room, and does not move his head or hands. If he feels uncomfortable, he can tell the doctor;

5) If any suspicious findings are found during the examination, a biopsy is required. This is a less invasive examination and you do not need to be too nervous. After the biopsy, there may be a short-term small amount of bleeding. Do not suction or blow your nose vigorously. Stay for observation for about half an hour. If there is no active bleeding, you can go home and rest. Avoid hot and irritating foods.
