Things to note before doing an ultrasonic gastroscopy

Gastroscopy is a method of examination that can observe the esophagus, stomach and duodenum of the human body. If there is a disease in this area, it can be detected in time through gastroscopy, and the severity of the disease can also be discovered, which is very helpful for later treatment. However, before the examination, you must be well prepared, especially to understand the precautions. So what are the precautions before doing ultrasonic gastroscopy?

First, what are the precautions before doing ultrasonic gastroscopy? Do not smoke the day before to avoid intubation affected by coughing during the examination; no smoking can also reduce gastric acid secretion, making it easier for doctors to observe. The patient must fast for at least 6 hours before the examination. If the examination is conducted in the morning, you should fast after dinner the day before and skip breakfast on that day. If the examination is conducted in the afternoon, you can eat light semi-liquid food for breakfast and fast at noon. Patients with severe illness or weak constitution may have difficulty supporting themselves after fasting, and hypertonic glucose solution should be injected intravenously before examination.

Second, in order to eliminate the patient's nervousness, reduce gastric juice secretion and gastric motility, expel the foam in the stomach, and make the image clearer, the doctor should give the patient sedatives, antispasmodics and defoaming agents 20-30 minutes before the examination if necessary. Patients should understand this and cooperate with it.

Third, in order to allow the gastroscope to pass through the pharynx smoothly, the pharyngeal medication instructions are generally required before gastroscopy, and the patient must follow the doctor's requirements. Local analgesia is used for pain relief, limited to the throat and upper esophagus. Before using the above-mentioned medicines, tell your doctor your history of drug allergy, that is, what drugs you were allergic to in the past. Local analgesia is achieved by spraying 2% dicaine or 2% xylocaine. The patient opens his mouth and makes an "ah" sound. The soft palate and palatoglossal arch move up, and the root of the tongue moves down, so that the back of the tongue, throat, and soft palate are sprayed with the medicine. This is repeated three times. After each spray, the patient swallows the remaining medicine in the mouth to relieve pain. There are also pastes that are held in the mouth and the head tilted back so that the medicine stays in the throat and naturally flows into the esophagus, thereby achieving a local analgesic effect.

What are the precautions before doing ultrasonic gastroscopy? The patient and the doctor should cooperate. Before the examination, the patient should go to urinate to empty the bladder. After entering the examination room, loosen the collar and belt, take off dentures and glasses, lie on the left side, or change to other positions as needed. After inserting the mirror, do not bite it with your teeth to avoid biting the plastic tube of the mirror body. The body and head cannot be rotated to avoid damaging the mirror and injuring the internal organs. If there is any discomfort, the patient can endure it for a while. If it is unbearable, he or she can use gestures to signal the operator (doctor or nurse) so that necessary measures can be taken.
