About this study

Official title: Neural Triggering and Cycling-off of Pressure Support Ventilation Improves Synchrony and Reduces Inspiratory Effort in Chronic Obstructive Pulmonary Disease.

Acute exacerbation of chronic obstructive pulmonary disease patients with intrinsic positive end-expiratory pressure (PEEPi), Neurally adjusted ventilatory assist (NAVA) reduce work of breathing and trigger delay at any external positive end-expiratory pressure (PEEPe) level compared with pressure-support ventilation (PSV)

Read the detailed description

All patients randomly underwent a 30 mins PSV and NAVA crossover ventilation (15 mins each) at progressive PEEPe levels. Progressive levels of PEEPe were applied stepwise in increments of 40% of baseline static PEEPi, every 30 mins, from zero to 160% of baseline static PEEPi during the protocol (0, 40%, 80%, 120% and 160% of static PEEPi, respectively). During PSV, pressure support level was set to meet a Vt 6ml/kg, I/E cycling was 30% of the maximum inspiratory peak flow, flow trigger was 1L/min, and inspired fraction of oxygen (FiO2) was set to the similar level before the study protocol. During NAVA, NAVA Level was set at 15 cmH2O / µV and a peak airway pressure limit was set in order to apply the same inspiratory pressure support at each PEEPe level during PSV. The new setting of NAVA was defined as NAVA15. Moreover the trigger was set at 0.5 µV and the I/E cycling fixed at 70% of the peak of EAdi. During the entire protocol, FiO2 and peak air way pressure were maintained the same levels at each PEEPe level between PSV and NAVA. Arterial blood gases were measured at the end of PSV or NAVA15 ventilation at each PEEPe level.

Questions about this trial

What is this clinical trial studying?

A study testing PEEP titration in people with Acute Exacerbation Chronic Obstructive Pulmonary Disease, run by Southeast University, China at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Jul 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

trigger work of breathing (time frame: 1 day). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02114567, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Jul 2014.
