Precautions before gastroscopy
1. Smoking is prohibited on the first day, so as not to affect intubation due to cough during examination. Smoking can also reduce gastric acid secretion, which is convenient for doctors to observe.
2. Don't eat or drink water at least 8 hours before the examination. Food in the stomach will easily affect the doctor's diagnosis, and it will easily lead to nausea and vomiting.
3. Patients should be on an empty stomach for at least 6 hours before the examination. If you check in the morning of the same day, you should fast after dinner the day before, and breakfast is free on that day. If you check in the afternoon, you can eat light and semi-liquid food for breakfast and fast at noon.
4. Patients who are severely ill and physically weak and unable to support after fasting should be injected with hypertonic glucose solution intravenously before examination.
5. In order to eliminate the patient's nervousness, reduce gastric juice secretion and gastric peristalsis, expel the bubbles in the stomach and make the image clearer, if necessary, the doctor should give the patient sedatives, spasmolytics and defoamers 2-3 minutes before the examination.
6. In order to reduce throat discomfort, the medical staff will spray anesthetic on the throat of the patient 3 minutes before the examination. In this regard, patients should understand and cooperate.
7. In order to make the gastroscope pass through the pharynx smoothly, medication is usually used before gastroscopy. Before taking the medicine, explain to the doctor your history of drug allergy, that is, what drugs you were allergic to in the past.
8. local analgesia is used to relieve pain, which is limited to the upper end of the throat and esophagus. Local analgesia is to spray 2% dicaine or 2% serocaine. When the patient opens his mouth, he makes an "a" sound. At this time, the soft palate and the arch of the tongue and palate move up, and the base of the tongue moves down, so that the medicine is sprayed on the back of the tongue, throat and soft palate for three times. After each spray, the patient will swallow the medicine left in the mouth to relieve pain in the pharynx.
9. Paste can also be used, which is contained in the mouth and lifted upward to make the medicine stay in the throat and naturally flow into the esophagus, thus playing a local analgesic role.
1. The patient should cooperate with the doctor. Before the examination, the patient should urinate and empty the bladder. After entering the examination room, loosen the neckline and waistband, remove the dentures and glasses, and take the left lateral position, or switch to other positions as needed.
Gastroscopy process and precautions
1. Gastroscopy is a slender tube with a diameter of about 1 cm wrapped in black plastic, and the front end is equipped with an endoscope that extends from the mouth into the esophagus → stomach → duodenum of the subject. With the strong light from the light source, the light can turn through the light guide fiber, so that doctors can clearly observe the health status of various parts in the upper digestive tract from the other end. If necessary, a small hole in the gastroscope can be inserted into the clip for biopsy.
2. The whole examination time is about 1 minutes, and it will take 2 to 3 minutes if biopsy is done.
3. The doctor will make the patient lie on his side and bend his legs. Ask the patient to hold the mouth pad and bite it gently. The nurse fixes the mouth pad with her left hand and stands at the front end of the patient's body 2cm with her right hand. Ask the patient to take a deep breath through her nose, keep her head still and relax her whole body. The gastroscope enters her mouth through the mouth pad. When inserting the tongue base to the entrance of esophagus, ask the patient to swallow, so that the gastroscope can pass through the pharynx smoothly.
4. In general gastroscopy, doctors usually hold the front end of the gastroscope with their right hand and slowly put the gastroscope into the mouth to the base of the tongue, which often leads to nausea. When nausea is obvious, or when swallowing, the upper mouth of the esophagus will be open, and the doctor will insert the gastroscope into the esophagus along the opening at the moment of opening.
5. If there is resistance in the process of inserting the endoscope, you can't force intubation. Let the patient rest for a while, and then send the end by swallowing.
6. During the lens insertion, the doctor will closely observe the patient's breathing, complexion, etc. At the same time, he will constantly give a simple explanation to the patient and instruct him to take a deep breath. Don't swallow saliva and let it naturally flow out of the curved plate. For those who need biopsy, the biopsy forceps should be used to take the focus tissue stably, accurately, lightly and carefully, put it in 1% formalin solution for fixation, and send it for inspection in time. 7, after entering the mirror, the patient can't bite the mirror with his teeth, in case of biting the plastic tube of the mirror body. The body and head can't rotate to avoid damaging the mirror and hurting the internal organs. If there is discomfort, the patient can't bear it for a while, so he can sign to the operator (doctor or nurse) to take necessary measures.
8. During the inspection, first put on loose clothes, and take a left lying position with legs slightly bent. When the doctor puts the gastroscope into the patient's mouth with a plastic device, he should relax all over and swallow slightly, so that the gastroscope can smoothly enter the esophagus through the throat. When you pass through your throat, you will feel pain and want to vomit for several seconds, which is a more uncomfortable moment during gastroscopy.
9. When making a diagnosis, doctors should not swallow, but inhale through the nose and exhale slowly in the mouth, so that the examination can be completed smoothly. Some people will feel flatulence and nausea because air enters the stomach with the tube.
1. If you feel pain and discomfort, please make a gesture to the medical staff, and never grab the tube or make a sound.
Precautions after gastroscopy
1. After the examination, the patient sat up and spit out saliva. Because some air was injected during the examination, although it was sucked out when leaving the mirror, some people still felt abdominal distension and a lot of belching.
2. There may be pain or foreign body sensation in the pharynx, and the symptoms can be alleviated or disappeared by delicious iodine-containing throat tablets and grass coral buccal tablets.
3. It's best to have a family member to accompany you for gastroscopy, and escort you home after the examination.
4. Patients who have undergone biopsy (especially the elderly) should not eat within 1 to 2 hours after the examination. If the throat does not feel uncomfortable, they can drink water first. If you don't choke, you can eat soft food first to avoid bleeding in the esophagus or stomach caused by rough food.
5. within 1 ~ 2 days after the examination, you should eat a semi-liquid diet and avoid raw, cold, hard and irritating food.
6. Smoking, drinking, drinking strong tea and strong coffee are prohibited to avoid bleeding on the wound surface.
7. Some people will have a brief sore throat and foreign body sensation, which usually can be recovered in 1 to 2 days.
8. Patients may feel discomfort or pain in the pharynx, but it does not hinder their diet. Most people can work as usual, and those with more illnesses can take a rest. Drivers cannot drive alone that day.
9. When the analgesic effect has not disappeared, eating too early will easily cause food to enter the trachea and cause choking or aspiration pneumonia, so don't eat too fast.
