NCT ID NCT07640243
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two types of sedation used during a procedure to drain blocked bile ducts. About 98 adults will receive either propofol-remifentanil or propofol-ketamine. The goal is to see which method leads to faster recovery, better comfort, and fewer side effects, especially in older or fragile patients.
