Myths, fallacies and practical pearls in GI lab

Area of Science:

• Gastroenterology
• Anesthesiology
• Medical Practice Guidelines

Background:

• Current gastrointestinal (GI) endoscopy and procedural sedation practices often contradict scientific evidence.
• Prevalent guidelines may not reflect the latest physiological and clinical outcome data.

Purpose of the Study:

• To review and challenge common myths and outdated practices in GI endoscopy and procedural sedation.
• To promote evidence-based changes in institutional policies and clinical practices.

Main Methods:

• Literature review and critical analysis of existing scientific-physiological and clinical outcome data.
• Examination of prevalent institutional policies and guidelines versus published evidence.

Main Results:

• Extended pre-procedural fasting lacks evidence of benefit and may be unnecessary.
• Routine supplemental oxygen administration can hinder early detection of hypoventilation during sedation.
• Propofol use by gastroenterologist-nurse teams is safe and effective, contrary to some institutional prohibitions.
• Many advocated monitoring practices offer little value, and technological advances are slow to be adopted.

Conclusions:

• Outdated practices in GI endoscopy and procedural sedation should be revised based on current scientific evidence.
• Adoption of evidence-based guidelines can improve patient safety, satisfaction, and cost-effectiveness.
• Challenging established myths is crucial for advancing GI procedural care.
