NCT ID NCT05950646

First seen Jul 06, 2026 · Last updated Jul 07, 2026 · Updated 1 time

Summary

This trial tests whether a very low dose of two drugs—dexmedetomidine and esketamine—given at night can improve sleep quality in older adults (65-89 years) undergoing knee or hip replacement. Poor sleep after surgery is common and linked to worse recovery. The study compares the drug combination to a placebo, measuring sleep quality through questionnaires and wearable monitors.
