About this study
Currently, the tools available for assessing peripheral muscle dysfunction in the intensive care setting require patient collaboration. Several studies have shown that peripheral muscle ultrasound is capable of reliably detecting morphological changes in critically ill patients, in addition to contributing to the identification of patients at higher risk of prolonged complications, especially when performed daily. In this sense, a valid, non-volitional alternative capable of determining muscle mass is through ultrasound assessment. However, current studies are characterized by a lack of standardization in their protocols, which include proper positioning of limbs, transducer, clear reference points and techniques for better visualization of the assessed muscle, in addition to significant methodological defects and inadequate sample sizes. We believe that, together with a tool capable of determining muscle mass and being a safe and non-invasive method, we can contribute to a more complete assessment of these patients, exploring outcomes such as survival, length of stay in the ICU, extubation success and functional capacity. In addition to having the potential to serve as a biomarker of muscle strength during rehabilitation, given little knowledge about the long-term physical consequences of COVID-19, thus promoting a more complete assessment, exploring morphological characteristics of the peripheral muscles resulting from the hospitalization process. and assisting the physiotherapist in clinical decision making in rehabilitation.
Read the detailed description
Introduction: the length of hospital stay may be associated with factors such as the need for mechanical ventilation, severity of the underlying disease, infections, use of sedation and neuromuscular blockers. In this context, the new coronavirus (SARS-CoV-2) presents itself as a group of viruses that can cause acute respiratory syndromes with mild and severe symptoms, contributing to increased hospital stays and periods of immobility. Peripheral muscle measurement through ultrasound is a topic of growing interest in the assessment of critically ill patients. Currently, this tool has been shown to be able to assess muscle dimensions and morphology during hospitalization in the intensive care unit (ICU) and can be performed at the bedside, presenting itself as a reliable inter and intraobserver method. As this tool does not depend on patient collaboration and is a non-invasive method available in most ICUs, it can provide additional information to the physical examination and clinical impression.
Objective: to evaluate the evolution of ultrasound pattern measurements in mechanically ventilated patients admitted to the ICU.
Methods: prospective cohort study that will be carried out in the ICU of the Recife Women's Hospital, located in Recife - PE, with individuals of both genders, over 18 years old, under mechanical ventilation due to suspicion or confirmation of COVID- 19. To carry out this study, the measurement of the ultrasound pattern of peripheral muscles will be performed from admission to the ICU, with follow-up on the 3rd, 5th and 7th days under mechanical ventilation. The length of stay in the ICU and mechanical ventilation, mortality in this population will also be evaluated. Clinical, laboratory, oxygenation, ventilation, respiratory system mechanics data will also be analyzed. Data will be collected and archived for analysis, which considers differences between groups with p<0.05. All ethical principles will be respected with either written Free and Consent Term by the patient or relatives at the intensive care phase or at the post ICU discharge phase.
Expected results: to contribute to a more complete assessment of these patients, exploring outcomes such as survival, length of stay in the ICU and effects of immobility on peripheral muscle mass.

Questions about this trial
What is this clinical trial studying?
An observational study of COVID-19 Respiratory Infection, run by University of Pernambuco at 1 site in Brazil.
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 1 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 2 Aug 2022. 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 Brazil. 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?
Peripheral muscle thickess measured during ultrasonography (time frame: 25 minutes). 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 NCT05055440, which also lists 16 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 2 Aug 2022.
