Routine premedication during gastroscopy can cause severe hypoxemia, particularly in older patients or those with anemia. Careful monitoring and prophylactic oxygen are recommended to mitigate risks associated with this common procedure.

Area of Science:

  • Gastroenterology
  • Cardiorespiratory Medicine

Background:

  • Routine premedication for gastroscopy is common but its necessity and safety are debated.
  • Serious cardiorespiratory complications, though rare, can occur during gastroscopy.
  • Current practices often lack vital sign monitoring during premedication.

Purpose of the Study:

  • To investigate the impact of gastroscopy premedication on patient oxygen saturation.
  • To identify patient groups at higher risk for complications.
  • To evaluate the effectiveness of prophylactic oxygen administration.

Main Methods:

  • Observational study involving 101 patients undergoing gastroscopy.
  • Continuous monitoring of oxygen saturation before, during, and after the procedure.
  • Analysis of complications in relation to premedication use, patient age, and anemia status.

Main Results:

  • A decrease in oxygen saturation was observed in most patients, typically minor.
  • Severe hypoxemia occurred in a subset of patients, notably those who received premedication.
  • Older patients and those with severe anemia were identified as high-risk groups.

Conclusions:

  • Premedication for gastroscopy requires cautious use and vigilant monitoring, especially in high-risk individuals.
  • Prophylactic oxygen administration can significantly reduce the risk of hypoxemia during gastroscopy.
  • The findings support a re-evaluation of routine premedication protocols in gastroscopy.
