What medicine should I drink before doing gastroscopy
Gastroscopy is an important means of diagnosing upper gastrointestinal diseases, and patients usually need to take specific drugs to optimize the effectiveness of the test before the examination. This article will combine popular topics and hot contents across the network for the past 10 days to analyze in detail what medicine was consumed before gastroscopy, and present relevant information with structured data.
1. Commonly used drugs before gastroscopy
Before gastroscopy, doctors usually recommend patients to take the following medications to ensure smooth examination and improve diagnosis accuracy:
| Drug name | effect | Time of taking |
|---|---|---|
| Silicone oil | Eliminates gastric bubbles and improves visual clarity | 30 minutes before the inspection |
| Lidocaine glue | Local anesthesia of the throat to reduce vomiting reflex | 5-10 minutes before inspection |
| Streptomyces | Decompose gastric mucus to improve lesion detection rate | 20-30 minutes before inspection |
2. Mechanism of action and precautions
1.Silicone oil: This is a defoaming agent that can reduce the surface tension of bubbles in the stomach and cause them to rupture, thereby reducing the interference of bubbles on the observation of gastric mucosa. Appropriate activity is required after taking it to help the medication be evenly distributed.
2.Lidocaine glue: As a local anesthetic, it can temporarily inhibit the sensitive nerves in the throat and relieve nausea when the gastroscopy passes. Some patients may experience short-term oral numbness, which is normal.
3.Streptomyces: This drug can decompose the mucus layer in the stomach, exposing the gastric mucosa to the gastric mucosa more clearly, and is especially helpful in the detection of tiny lesions such as early gastric cancer. Drink a small amount of water after taking it to promote the distribution of the drug.
3. Summary of popular issues across the entire network
Based on search data from the past 10 days, the following are high-frequency questions about pre-gasposcope medications:

4. Experts suggest sharing experience with patients
1.Medication taste: Lidocaine glue is often described as "slightly sweet and bitter", while simethanol is mostly odorless or slightly mint-flavored. You can communicate with the doctor in advance and choose medicines that suit your taste.
2.Allergy history declaration: If you have a history of allergic to local anesthetics or protease drugs, you must clearly inform your doctor before the examination, and if necessary, you can use other pretreatment plans.
3.Special treatment for children: For children under 12 years old, the drug dosage is usually required, and some hospitals will provide fruity additives to improve medication compliance.
5. Summary
Drug preparation before gastroscopy is a key link in ensuring the quality of the examination. By rationally using defoaming agents, local anesthetics and mucus scavengers, the detection rate of lesions and patient comfort can be significantly improved. It is recommended that patients take the medicine strictly as precautions and understand the relevant precautions in advance to complete the examination smoothly.
