Continuous monitoring during endoscopy revealed that 24% of patients experienced hypoxemia (low oxygen levels). Nine patients required treatment for this condition, highlighting the need for careful monitoring during gastrointestinal procedures.

Area of Science:

  • Gastroenterology
  • Cardiopulmonary Monitoring

Background:

  • Gastrointestinal endoscopy procedures like esophagogastroduodenoscopy and colonoscopy are common.
  • Monitoring vital signs during these procedures is crucial for patient safety.

Purpose of the Study:

  • To assess the incidence of hypoxemia and tachycardia during esophagogastroduodenoscopy and colonoscopy.
  • To determine the need for intervention in patients experiencing adverse cardiopulmonary events.

Main Methods:

  • Continuous pulse oximetry was used to monitor arterial oxygen saturation and heart rate.
  • 100 consecutive patients undergoing either esophagogastroduodenoscopy or colonoscopy were included.

Main Results:

  • Twenty-four patients (24%) developed hypoxemia (arterial PO2 < 60 mm Hg).

  • Nine patients required treatment for hypoxemia; 15 experienced transient episodes.
  • Twenty patients developed tachycardia (> 120 beats/minute).

    • Conclusions:

    • Hypoxemia and tachycardia are significant risks during gastrointestinal endoscopy.
    • Continuous cardiopulmonary monitoring is essential for early detection and management of these complications.
