About this study

Official title: Clinical Evaluation of Ventilator Innovation Product in Colombia in the SARS Pandemic Covid 19, Unisabana Herons - A Cohort Study - Phase 1

The objective of this study is to evaluate the efficacy and safety of the Unisabana-Herons invasive mechanical ventilator designed to provide the basic ventilatory support necessary to preserve the life of patients with respiratory failure and indication of mechanical ventilation, especially for those who suffer from acute respiratory distress syndrome (ARDS) when conventional commercial invasive ventilators are not available in the context of the health emergency due to the COVID-19 epidemic.

The Unisabana-Herons ventilator allows to precisely configure the respiratory rate, tidal volume (or inspired air volume), inspiratory time, the inspiration: expiration ratio, the positive pressure at the end of expiration (PEEP), the inspired fraction of oxygen and inspiratory air flow, parameters that allow managing the respiratory failure associated with COVID-19. The ventilator also monitors peak inspiratory pressures (PIP), mean, PEEP, plateau, and graphs in real time the pressure-time, volume-time, flow-time curves, which allows detecting when one of these is at levels dangerous to induce ventilator trauma (barotrauma and volutrauma) and thus ensure effective and safe ventilation, so as to avoid ventilator-induced lung injury.

Read the detailed description

The Unisabana-Herons ventilator is an invasive mechanical ventilator that works on the same principles of invasive positive pressure mechanical ventilators that have existed for 80 years. Although the effectiveness of ventilatory assistance in saving human lives was known since biblical times, the first mechanical ventilators only appeared in 1800 and it was in 1900 when the first positive pressure ventilators were manufactured, which have a turning point in 1940 as a result of the polio epidemic, when invasive positive pressure mechanical ventilators were developed that could be used massively and have evolved to current models. These positive pressure fans completely replaced the first negative pressure models, have abundant support in the scientific literature, and are the most commonly used today.

Since the beginning of the COVID-19 epidemic in Colombia, the University of La Sabana, a multidisciplinary team in order to find solutions to deal with the disease, and its first project, consisted in the design and manufacture of an invasive mechanical ventilator (Ventilator Unisabana-Herons) able to supply the basic ventilatory needs of the patient with severe respiratory failure due to COVID-19 at the time when the installed capacity of classic commercial mechanical ventilators is exhausted. The Unisabana-Herons ventilator was built based on those recommended by INVIMA, the MHRA (UK Medicines and Devices Regulatory Agency) and the FDA, to provide efficient and safe volume controlled ventilation to patients with indications. of mechanical ventilation for respiratory failure according to the ventilatory modes already affected that have strong scientific evidence.

This study seeks to evaluate the effectiveness, usability and safety of the Unisabana-Herons ventilator for the management of patients with an indication for invasive mechanical ventilatory support, admitted to level III and IV university hospitals with Intensive Care services enabled through a cohort study of 5 patients with a 24-hour follow-up.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Invasive mechanical ventilation using the Unisabana-Herons Ventilator during 24 hoursDevice

    Recruited patients will receive volume-controlled mechanical ventilation (assist-control mode) using the Unisabana-Herons ventilator for 24 hours. Information on clinical, hemodynamic, and respiratory variables will be recorded from 30 minutes before the start of mechanical ventilation with the Unisabana-Herons ventilator. Recordings will be made in the first 4 hours every 15 minutes in the CFR, except for arterial blood gases which will be taken every 30 minutes. In the following 20 hours, arterial blood gas controls will be taken at hour 12 from the start of the ventilator and at hour 24. Other hemodynamic and respiratory variables will be recorded every hour from hour 4 of ventilator start until hour 24.

The record lists 3 sites in Colombia. 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?

Improvement or maintenance of the oxygenation level measured by PaO2 (time frame: 24 hours). The study lists 2 primary outcomes in all. 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 NCT04497623, which also lists 6 linked publications.

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 24 Sep 2020.
