Conscious sedation with propofol in elderly patients: a prospective evaluation

Area of Science:

• Geriatric Medicine
• Gastroenterology
• Anesthesiology

Background:

• Elderly patients often have comorbidities, raising concerns about sedation safety during endoscopic procedures.
• Propofol is a common anesthetic agent, but its safety in the very elderly requires careful evaluation.

Purpose of the Study:

• To assess the safety and tolerability of endoscopic procedures with nurse-administered propofol sedation in elderly patients.
• To compare outcomes in different age groups of elderly patients and with younger controls.

Main Methods:

• Prospective observational study of 1786 elderly patients (>70 years) undergoing endoscopy.
• Patients were divided into two groups: 70-85 years (Group A) and >85 years (Group B).
• Trained nurses administered propofol and monitored vital signs; younger patients served as controls.

Main Results:

• No mortality related to procedures or sedation occurred in elderly groups.
• Elderly patients showed a higher risk of transient oxygen desaturation but not more severe complications.
• Arterial hypotension was more frequent in the younger control group.

Conclusions:

• Gastrointestinal endoscopic procedures are safe and well-tolerated in the very elderly population.
• Nurse-administered propofol sedation is a safe and effective method for elderly patients undergoing endoscopy.
