In the gastroscope room of the endoscopy center, the patient Mr. Liu lay flat on the hospital bed according to the doctor's instructions, opened his mouth, and the doctor gently put the probe into Mr. Liu's mouth. Immediately, Mr. Liu's face showed a painful expression. With the progress of the operation, Mr. Liu kept twisting his body and showed symptoms of nausea, nausea and pain. This process lasted nearly 6 minutes. After that, Mr. Liu looked scared and even said, "I will never do a gastroscope again. It's too painful."

At the same time, in another gastroscope room, Ms. Li, a patient, was lying quietly in the hospital bed according to the doctor's instructions. The doctor inserted a needle in her right hand vein and the liquid medicine was slowly injected into her body. After a while, Ms. Li fell asleep, and she didn't know anything about the later process. After Ms. Li woke up, all the inspections had been completed.

This is the now popular painless gastroscope. The principle of painless gastroscope is to inject sedative drugs into patients, so that patients are in a state of sleep, and doctors complete all examinations in a state of sleep.

For some sensitive patients, painless examination can reduce discomfort during examination, such as nausea, nausea and pain. Let the patient cooperate with the doctor in a calm process and successfully complete the examination.

But patients should also pay attention to painless gastroscopy. Because patients are asleep during painless gastroscopy, they can't deal with improper operation in time, which may cause greater damage to digestive tract, such as scraping esophagus and bleeding. At the same time, painless gastroscopy also reduces the operating requirements for doctors, and it is difficult to improve the professional level of doctors.

How to choose a suitable gastroscope is the most important.

1. General gastroscope

Ordinary gastroscope is a intubation examination method, which is inserted into the stomach with the help of a slender and flexible tube. Doctors can directly observe the pathological changes of the mucosa of esophagus, stomach and upper duodenum, and take a small amount of mucosal tissue from suspicious lesions for pathological examination, which can greatly improve the accuracy of the examination.

trait

Gastroscopy will not cause pain, and the main discomfort is nausea. Generally, patients with pharyngeal sensitivity who are highly fearful, nervous, obese, short in head and neck, and prone to nausea when smoking and brushing teeth will have a greater reaction during gastroscopy.
