Sedation-free colonoscopy is well-tolerated and accepted by most patients, with rare complications. This cost-effective and potentially safer procedure should be offered as an alternative to traditional colonoscopy with sedation.

Area of Science:

  • Gastroenterology
  • Endoscopy
  • Patient Safety

Background:

  • Sedation in colonoscopy presents drawbacks, including increased complication rates and costs.
  • Sedation-free colonoscopy offers potential advantages in terms of safety and cost-effectiveness.

Purpose of the Study:

  • To evaluate patient tolerance and acceptance of sedation-free colonoscopy.
  • To assess the feasibility and patient experience of undergoing colonoscopy without sedative drugs.

Main Methods:

  • A prospective study of 675 patients undergoing sedation-free colonoscopy.
  • Evaluation of patient pain using a four-point scale, willingness for future procedures, complication rates, and intubation times.
  • Independent pain assessment by patients and endoscopy nurses immediately post-procedure.

Main Results:

  • 99.6% of colonoscopies were successful with a low complication rate (four cases of bleeding after polypectomy).
  • Patients reported minimal pain: 69.6% nil, 28.0% mild, 2.2% moderate, 0.1% severe.
  • Only 1.0% of patients expressed unwillingness to undergo future sedation-free procedures due to pain.

Conclusions:

  • Carefully performed sedation-free colonoscopy is safe, well-accepted, and rarely causes complications.
  • Sedation-free colonoscopy is a viable, cost-effective, and potentially safer alternative to sedation-assisted procedures.
  • Offering sedation-free colonoscopy as an option can improve patient choice and procedural efficiency.
