Introduction: In Singapore, non-anaesthesiologists generally administer sedation during gastrointestinal
endoscopy. The drugs used for sedation in hospital endoscopy centres now include propofol in addition
to benzodiazepines and opiates. The requirements for peri-procedural monitoring and discharge
protocols have also evolved. There is a need to develop an evidence-based clinical guideline on the
safe and effective use of sedation by non-anaesthesiologists during gastrointestinal endoscopy in the
hospital setting.
Methods: The Academy of Medicine, Singapore appointed an expert workgroup comprising 18
gastroenterologists, general surgeons and anaesthesiologists to develop guidelines on the use of
sedation during gastrointestinal endoscopy. The workgroup formulated clinical questions related to
different aspects of endoscopic sedation, conducted a relevant literature search, adopted Grading of
Recommendations, Assessment, Development and Evaluation (GRADE) methodology and developed
recommendations by consensus using a modified Delphi process.
Results: The workgroup made 16 recommendations encompassing 7 areas: (1) purpose of sedation,
benefits and disadvantages of sedation during gastrointestinal endoscopy; (2) pre-procedural assessment,
preparation and consent taking for sedation; (3) Efficacy and safety of drugs used in sedation; (4) the
role of anaesthesiologist-administered sedation during gastrointestinal endoscopy; (5) performance
of sedation; (6) post-sedation care and discharge after sedation; and (7) training in sedation for
gastrointestinal endoscopy for non-anaesthesiologists.
Conclusion: These recommendations serve to guide clinical practice during sedation for gastrointestinal
endoscopy by non-anaesthesiologists in the hospital setting.
