What is an ordinary gastroscope? What is a painless gastroscope? General gastroscope: it is a medical examination method and also refers to the instruments used in this examination. With the help of a slender and soft tube, it extends into the stomach, so that doctors can directly observe the lesions of esophagus, stomach and duodenum, especially for minor lesions. Gastroscopy can directly observe the real situation of the examined site, and further diagnose it through pathological biopsy and cytological examination of the suspected lesion site. It is the first choice for upper digestive tract diseases.
Painless gastroscopy: On the basis of ordinary gastroscopy, propofol, fentanyl and lidocaine were injected intravenously. Intravenous fentanyl and propofol have sedative and analgesic effects, with quick onset, quick recovery, short half-life, strong controllability and no accumulation in the body. During gastroscopy, patients quickly fall into snoring and sleep state, and the cricopharyngeal muscles relax, which is helpful for gastroscopy.
What is the difference between painless gastroscope and ordinary gastroscope? During the examination, the common gastroscope stimulates the patient's pharynx greatly, and the patient is prone to nausea and vomiting, which leads to long operation time, unclear gastric cavity exposure, mechanical injury, unstable vital signs such as heart rate and blood pressure, and even death in severe cases. Due to various reasons, most patients are unwilling to accept examination and delay treatment.
In the process of painless gastroscope implementation, endoscopists and anesthesiologists cooperate with each other to complete it together. At present, propofol injection is commonly used in painless gastroscopy, which has the advantages of quick onset (30s), short action and rapid recovery from anesthesia, and is recognized and accepted by the majority of patients. The ideal anesthesia makes patients have no stress response to stimulation examination, and receive examination in a comfortable, painless and memoryless deep sleep state, which improves patients' satisfaction and reduces patients' anxiety. Endoscopists can observe the patient's examination site comprehensively and carefully, and anesthesia can effectively reduce the gastric juice secreted by gastroscope stimulation, and gastric peristalsis is also inhibited to a certain extent, which improves the accuracy of observation.
Painless gastroscopy also has the following advantages: 1, painless: Painless gastroscopy is the best choice for patients who are nervous and afraid of gastroscopy, because the subjects will not feel any discomfort during the examination and treatment of painless gastroscopy.
2. Minimal trauma: Under the painless electronic gastroscope, multiple minimally invasive treatments can be performed for gastrointestinal bleeding, polyps and ulcer stenosis, so that patients can avoid the pain of surgery.
3. Short time: excluding the preparation time before the inspection, it can be completed within a few minutes from the beginning of the inspection.
4. More accurate: Painless gastroscopy has advantages that can't be replaced by other examination methods at present, especially minor lesions and even mucosal lesions, which can make a definite diagnosis and have the function of amplification, further increasing the accuracy of diagnosis.
5. High accuracy: Another advantage of painless gastroscopy is its high diagnostic accuracy. It has the advantages of good image quality, large screen, clear image, high resolution, large bending angle and flexible control. Through it, doctors can directly observe the internal situation of digestive tract with naked eyes, find ulcers, polyps, diverticulum inflammation and other lesions, and see subtle changes such as mucosal congestion, edema and discoloration, and can biopsy under direct vision. At the same time, it also has many functions such as storage, video recording and photography. , convenient for reference and data preservation. By comparing the data before and after the examination, we can clearly know how the treatment effect is, understand the progress of diagnosis and treatment, and have more confidence in the treatment.
However, painless gastroscopy is not without its shortcomings. Painless gastroscope is expensive, and anesthesia also has certain risks. In particular, patients with cardiovascular diseases, liver diseases and poor kidneys should be cautious and strictly master the indications and contraindications of painless gastroscopy. So who can't do a painless gastroscope? Are there any precautions after painless gastroscopy? 1. Absolute taboo population 1, severe coronary heart disease and myocardial injury with severe cardiac insufficiency. 2. Esophageal stenosis or heart obstruction. 3. aortic aneurysm. 4. hemorrhagic shock. 5, acute pharyngitis and tonsillitis. 6, pneumonia or other infections accompanied by high fever. 7. Asthmatic dyspnea. 8. Severe pulmonary dysfunction. 9. Extremely weak. 10, the patient is unwilling to cooperate or mentally abnormal. Second, people who are relatively taboo, acute attacks of acute diseases or chronic diseases, can be recovered after treatment, such as acute gouty arthritis, pharyngitis, esophagitis and bronchial asthma.
Precautions after painless gastroscopy: Rest in the waiting area for more than half an hour, and leave with your family after no dizziness, drowsiness and other discomfort; Don't sleep for 3 hours (to avoid respiratory depression caused by sedative residues and drowsiness of patients); Fasting and water prohibition within 3 hours (to avoid swallowing anesthetics still works, and secretions mistakenly enter the trachea to cause suffocation or aspiration pneumonia); After painless gastroscopy, don't go out alone for 24 hours, and don't ride a bike, drive a car, work high above the ground or sign documents for 24 hours (to avoid the influence of sedative residues); For patients after biopsy and treatment, precautions such as fasting water after operation should be followed by doctor's advice in gastroscope room.
