How to Rescue Asphyxiation During Painless Gastroscopy?

Asphyxia during painless gastroscopy can be rescued through rapid respiratory tract cleansing, oxygen therapy, medication injection, etc.

1. Rapid Respiratory Tract Cleansing: During painless gastroscopy, anesthetic drugs are usually injected to facilitate the examination. Generally, asphyxia does not occur. When a patient undergoes painless gastroscopy, asphyxia may be caused by vomiting due to gastrointestinal stress reactions, with vomit blocking the respiratory tract, leading to asphyxia. Rapid respiratory tract cleansing is required to maintain smooth breathing, and oxygen therapy should be administered simultaneously to avoid hypoxic symptoms.

2. Medication Injection: If the patient aspirates due to an allergic reaction to anesthetic drugs, the painless gastroscopy should be immediately stopped, followed by the injection of chlorpheniramine maleate injection, dexamethasone sodium phosphate injection, and other medications for treatment. If necessary, drugs such as adrenaline hydrochloride injection can also be used for rescue. Painless gastroscopy is a relatively mature medical examination. Before the examination, doctors will make preliminary judgments based on the patient's constitution and specific conditions, and asphyxia is rare. Patients are advised not to worry too much.
