Research Progress on Prevention and Treatment of Hypoxemia in Painless Gastroscopy: A Review Article

Compared to ordinary gastroscopy, painless gastroscopy has more advantages due to the application of anesthesia techniques such as sedation and analgesia, providing patients with comfort and a quick recovery. However, patients undergoing painless gastroscopy are often at risk of hypoxia, which can result in serious complications. Fortunately, more anesthesia providers have recognized this problem. Therefore, it is essential for anesthesia providers to identify risk factors to prevent hypoxemia. In conclusion, this review highlights the assessment of risk factors for hypoxemia in painless gastroscopy and common airway management methods to prevent and treat hypoxemia in high-risk populations during painless endoscopy.
