A Placebo Controlled Trial Of L-Tryptophan In Post-Operative Delirium

University of Colorado, Denver·interventional·Posted Mar 19, 2009·Updated Jun 1, 2017

In Brief

A Phase 3 clinical trial evaluating L-tryptophan supplementation and placebo for Post-operative Delirium. Completed, enrolled 301 participants across 1 site.

Detailed Summary

Post-operative delirium is a common and deleterious complication in elderly patients. The investigators have previously found lower levels of serum tryptophan in post-operative elderly patients who developed delirium in comparison to post-operative elderly patients who did not develop delirium. The investigators hypothesize that post-operative supplementation of L-tryptophan will reduce the duration and incidence of post-operative delirium. This study is a double-blinded placebo controlled trial of L-tryptophan supplementation in post-operative ICU patients 60 years and older. The primary outcome measure is the comparison of duration of post-operative delirium in subjects who receive L-tryptophan supplementation versus a similar appearing control.
