Oxygen Inhalation Therapy Clinical Trial

Official title: Effect of a Double Trunk Mask Associated to Nasal Prongs During a High Flow Oxygenation Method

Status Completed

Clinical Trial Summary

The aim of this study is to determine the effect (on PaO2) of a modified mask associated to nasal cannula used for high flow oxygenation.

Clinical Trial Description

Study Design This is a single-center, randomized, blind investigator, 2-way crossover study design. Enrolled participants had severe hypoxia being treated at Intensive Care Unit associated with a hospital in Hornu (Epicura).

The study consisted of two intervention periods of 2 weeks separated by a washout period of 20 minutes. (Figure 1) The objective of the study is to determine whether adjunctive mask of our design (Double Trunk Mask - DTM) has an effect on increasing arterial pressure in Oxygen (PaO2) diagnosed with severe hypoxia.

The protocol and informed consent documents were reviewed and approved by a recognized ethics review board at the study facility. The study was performed in accordance with the Declaration of Helsinki.

Statistical Analysis

All participants who received this intervention and completed two phases of study were included in the efficacy analysis.

A sample size of 15 participants was needed to provide 90% power to detect a 10 mm Hg difference in PaO2. ANOVA for repeated measures followed by a post hoc test were used to compare the difference between participants receiving (CHFONP + DTM) and CHFONP alone.

The test was performed with a significance level of 0.05 (two-sided). Statistical analyses were carried out using SigmaPlot software version 11.0 (Systat Software Inc. UK).

Adverse Event Assessment

Safety was assessed by the number of participants with adverse events (AEs). AEs were collected by systematic assessment using terms from the Medical Dictionary for Regulatory Activities (MedDRA), version 11.1 in participants who received one or more doses of intervention. Adverse events during washout were not collected. ;
