Overview

Animal experimentals have shown that the more physiology-driven airway pressure release ventilation (APRV) methodologies in ARDS may significantly improve alveolar recruitment and gas exchange, increased homogeneity, and attenuate lung injury, without circulatory depression, as compared with conventional low tial volume lung protective ventilation. our previous single centre,random control study showed that clinical benefit for early use of APRV in ARDS. Nonetheless, clinical data on ARDS are still limited, most of them derived from small clinical trials in which variable outdated APRV settings were used, consequently, the findings of these studies were controversial.

Additionally, the previous single-centre,random control study showed that clinical benefit for APRV.Therefore,the investigators are ready to design a multiple centres,random control study to further verify the effect of APRV plus protocol in ARDS.

Description

All the patients included will be randomly assigned to receiving APRV plus protocol or low tidal volume ventilation.

Eligibility

Inclusion Criteria:

  • Moderate and severe acute respiratory distress syndrome,according to the Berlin definition of ARDS
  • receiving tracheal intubation and mechanical ventilation was no longer than 48 hours

Exclusion Criteria:

  • The expected duration of mechanical ventilation was less than 48 hours
  • Intracranial hypertension (suspected or confirmed)
  • Neuromuscular disorders that are known to prolong the need for mechanical ventilation

  • Terminal stage of disease
  • Pneumothorax (drained or not)at enrollment
  • Treatment with extracorporeal support (ECMO) at enrollment
  • There was a lack of commitment to life support.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
