About this study
Official title: Effects of Neuromuscular Blocking Agents on End Expiratory Lung Volume During Moderate-severe ARDS
This is a monocentric, prospective, observational study that will be conducted in the general ICU of San Gerardo Hospital (Monza, Italy). Study protocol will be started when NMBAs infusion will be stopped for clinical reason until regain of spontaneous breathing activity.
Patients will be enrolled at the moment of NMBAs infusion interruption ("baseline" phase). Clinical data will be collected: hemodynamics, ventilation parameters and respiratory mechanics, arterial blood gas analysis, drugs used for sedation and their dosages. An EIT belt will be positioned around the patient's chest when clinical signs of spontaneous breathing activity will be detectable (unstable flow curve on the ventilator, deflection in airway pressure during an expiratory pause). In this phase ("NMBA interruption") same clinical data will be collected as at baseline. Patients will be ventilated in the same ventilation mode as before (Volume Controlled mechanical ventilation), but the inspiratory trigger on the ventilator will be turned on to reduce patient-ventilator asynchronies. When an EIT trace lasting at least 10 minutes will be recorded, an NMBA bolus (as prescribed by the treating physician) will be administered and a continuous infusion will be restarted. Clinical data will be collected again in this phase ("NMBA restart").

What is being measured
The primary outcome is the main question the study is designed to answer.
End Expiratory Lung Volume
Patients will be enrolled at the moment of NMBAs infusion interruption ("baseline" phase). An EIT belt will be positioned around the patient's chest when clinical signs of spontaneous breathing activity will be detectable (unstable flow curve on the ventilator, deflection in airway pressure during an expiratory pause). In this phase ("NMBA interruption") same clinical data will be collected as at baseline. When an EIT trace lasting at least 10 minutes will be recorded, an NMBA bolus (as prescribed by the treating physician) will be administered and a continuous infusion will be restarted.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a monocentric, prospective, observational study that will be conducted in the general ICU of San Gerardo Hospital (Monza, Italy). Study protocol will be started when NMBAs infusion will be stopped for clinical reason until regain of spontaneous breathing activity.
Patients will be enrolled at the moment of NMBAs infusion interruption ("baseline" phase). Clinical data will be collected: hemodynamics, ventilation parameters and respiratory mechanics, arterial blood gas analysis, drugs used for sedation and their dosages. An EIT belt will be positioned around the patient's chest when clinical signs of spontaneous breathing activity will be detectable (unstable flow curve on the ventilator, deflection in airway pressure during an expiratory pause). In this phase ("NMBA interruption") same clinical data will be collected as at baseline. Patients will be ventilated in the same ventilation mode as before (Volume Controlled mechanical ventilation), but the inspiratory trigger on the ventilator will be turned on to reduce patient-ventilator asynchronies. When an EIT trace lasting at least 10 minutes will be recorded, an NMBA bolus (as prescribed by the treating physician) will be administered and a continuous infusion will be restarted.

Questions about this trial
What is this clinical trial studying?
An observational study of ARDS and Neuromuscular Blockade, run by University of Milano Bicocca at 1 site in Italy.
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 3 inclusion and 3 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 26 May 2023. 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 Italy. 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?
End Expiratory Lung Volume (time frame: Entire study duration (approx. 1 year)). 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 NCT04996394, which also lists 8 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 26 May 2023.
