Inhaled Nitric Oxide in Prevention/Treatment of Ischemia-Reperfusion Lung Injury Related to Lung Transplantation

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00060450
Recruitment Status : Terminated (Slow Enrollment)

Brief Summary:
The purpose of this study is to evaluate the effects of inhaled nitric oxide on both short-term physiology as well as on the development of ischemia-reperfusion lung injury (IRLI) in the immediate post transplant period. The specific hypothesis is that inhaled NO post lung transplantation will improve gas exchange/hemodynamic and thus reduce the development of post transplant IRLI.

Condition or disease Intervention/treatment Phase
Ischemia-Reperfusion Injury Drug: nitric oxide for inhalation Drug: Placebo Phase 3

Detailed Description:

The objective is to determine the role of inhaled NO in the prevention/treatment of IRLI in lung transplant patients. The plan is to accomplish this objective in 2 phases:

Phase 1 - patients immediately post transplant will have a variety of physiologic measurements performed while breathing 0, 10, and 20 ppm inhaled NO. For the next 24 hours they will be kept on a mixture providing the best oxygen delivery and pulmonary artery pressure. Our specific aims in this phase are to characterize physiologic responses to inhaled NO and determine the incidence of IRLI in these patients over 24 hours.

Phase 2 - patients immediately post transplant will be randomized to either INO or placebo gas and followed for 24 hours. Our specific aim in this phase is to compare the rate of development of IRLI in the two groups.
