Design: Multicentre, double-blind, placebo-controlled 2×2 factorial trial
Population: 360 adults aged 65–80 having bidirectional endoscopy
Primary outcome: Time to full alertness after the initial sedative dose
Effect: −1.42 min (95% CI −2.43 to −0.40); hypotension +15.6 points

A multicentre, double-blind factorial trial randomised 360 adults aged 65 to 80 having same-session gastroscopy and colonoscopy to oliceridine or placebo, with propofol or ciprofol.

Oliceridine cut the need for supplemental sedative doses (risk difference −16.7%) and shortened awakening by about 1.4 minutes, though that difference vanished when timed from the final dose. It increased hypotension by 15.6 percentage points. Propofol gave slightly faster awakening than ciprofol, under the 3-minute clinically important threshold.

In older adults the hypotension cost is real, and the time saved is small. This does not make an opioid adjunct a default.

Weigh hypotension risk before adding an opioid adjunct to sedation in older adults
Monitor blood pressure closely when combining opioids with propofol
Expect fewer supplemental doses but little real time saved
Note that oliceridine availability in India is limited

Why it matters

In older adults, small gains in sedation efficiency can be outweighed by haemodynamic cost.

The statistics, in plain English

A 15.6-point rise in hypotension means about one extra hypotensive patient for every six or seven treated. The 1.4-minute faster awakening is statistically significant but clinically small.
