During painless gastroscopy, the occurrence of hypoxia is a critical concern, especially under intravenous anesthesia using propofol. This study aimed to investigate the incidence of hypoxia during painless gastroscopy and evaluate preventive measures.
From June 15 th 2023 to August 15th 2023, 900 patients who underwent elective gastroscopy in the Renji Hospital, Shanghai Jiao Tong University School of Medicine were selected. They were divided into the high flow nasal cannula oxygen group and the conventional nasal cannula oxygen group by oxygen inhalation. Patient demographics, Mallampati class, and other relevant factors were compared between the two groups. Primary outcomes included the incidence hypoxia (SpO2 \< 90%), while secondary outcomes included subclinical respiratory depression, and adverse events related to nasal oxygen cannula.
