Study summary

Colonoscopy is a common endoscopic procedure as an investigation of colorectal pathology. Different modalities of pain control have been described in the past. Propofol is a perfect drug for endoscopic procedure since it has the characteristic of fast onset, short half-life and early recovery. Its unfamiliarity and its potential cardiovascular and respiratory side effect make it unpopular to endoscopists. Recent reports showed propofol is safe in bolus titration by nurse in Caucasian in all endoscopic procedures. Our previous pilot study showed nurse administered propofol sedation (NAPS) is effective and safe and highly acceptable by Chinese patients. Here we conduct a randomized controlled study to compare the effectiveness of NAPS versus traditional sedation.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 3, 2007, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
