Evidence Hub

A Randomized Controlled Trial of the Effects of Tadalafil and Dexamethasone Versus Placebo on Pulmonary Edema Formation and Cerebral Blood Flow Autoregulation in High Altitude Newcomers With a Previous History of High Altitude Pulmonary Edema

ClinicalTrials.gov · COMPLETED, 2003

30 participants

Abstract

A double-blind placebo controlled study

* To compare the effect of tadalafil and dexamethasone versus placebo on Ppa and pulmonary edema formation in subjects susceptible to HAPE.

* To investigate the effect of dexamethasone on alveolar fluid clearance, as assessed by measurement of the nasal potential difference, and prevention of HAPE.

* To investigate the effect of the tadalafil and dexamethasone versus placebo on the dynamic CBF autoregulation properties and on the development of AMS in HAPE susceptible subjects.

Conditions: High Altitude Pulmonary Edema.

Primary outcome: prevention of high altitude pulmonary edema.

Enrollment: 30 participants.

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 30 participants or records.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
