Evaluation of postprocedure cognitive function using 3 distinct standard sedation regimens for endoscopic procedures.

Area of Science:

• Anesthesiology
• Neuroscience
• Gastroenterology

Background:

• Sedation is commonly used for endoscopic procedures.
• Understanding the impact of different sedation regimens on cognitive function is crucial for patient recovery.
• Complications during sedation require timely intervention.

Purpose of the Study:

• To evaluate postprocedure cognitive function across three standard sedation regimens for endoscopic procedures.
• To identify complications necessitating provider interventions during sedation.

Main Methods:

• A randomized trial involving 96 subjects undergoing colonoscopies.
• Cognitive function assessed using Mini-Mental State Examination (MMSE) and Telephone Interview of Cognitive Status (TICS).
• Comparison of propofol alone, propofol plus fentanyl, and midazolam plus fentanyl sedation groups.

Main Results:

• The propofol-alone group showed no significant change in TICS scores at 24 and 48 hours (P = .924).
• Both groups receiving fentanyl (propofol-fentanyl and midazolam-fentanyl) demonstrated significant changes in TICS scores over time (P = .017 and P = .004, respectively).
• Significantly more jaw lift interventions were required in groups that received fentanyl.

Conclusions:

• Propofol-alone sedation has the least impact on postprocedure cognitive function.
• Sedation regimens incorporating fentanyl are associated with a higher incidence of complications requiring intervention.
• Propofol alone appears to be the preferred regimen for preserving cognitive function post-endoscopy.
