The Effects of Subanesthetic Ketamine on Respiratory Stimulation and Transpulmonary Pressures in Mechanically Ventilated Critically Ill Patients

Massachusetts General Hospital·interventional·Posted Oct 25, 2013·Updated May 19, 2026

In Brief

A clinical study evaluating Subanesthetic ketamine for Mechanical Ventilation and 2 related conditions. Completed, enrolled 15 participants across 2 sites.

Detailed Summary

Impairment of airway patency is a common cause of extubation failure and opioids and hypnotics can adversely affect airway patency. Ketamine, a noncompetitive antagonist of N-methyl-D-aspartate (NMDA), unlike other anesthetics activates respiratory effort and promotes bronchodilation. At subanesthetic plasma concentration, ketamine reduces both opioid and propofol requirements. The purpose of this pharmaco-physiological interaction trial is to evaluate the effects of ketamine on breathing and electroencephalography in mechanically ventilated patients.
