Trial summary

The purpose of this study is to monitor sleep in patients using breathing machines, because little is known about sleep when patients use masks to help their breathing. We'd like to compare sleep in patients using masks to that in patients with a tube in their throats. Read more about this study

About this study

Official title: Effects Of Invasive And Noninvasive Mechanical Ventilation On Sleep In The Icu

The purpose of this study is to monitor sleep in patients using breathing machines, because little is known about sleep when patients use masks to help their breathing. We'd like to compare sleep in patients using masks to that in patients with a tube in their throats.

Read the detailed description

Sleep in critically-ill patients is commonly severely fragmented, and sleep architecture is altered as compared to a healthy person. This abnormal sleep may cause some important adverse psychological and physiological consequences. Noise, light, patient-care activities, pain, or medications are some of the contributing factors to sleep disruption in the ICU. Recent evidence also suggests that invasive mechanical ventilation (IMV) itself may lead to sleep fragmentation in the ICU. Noninvasive ventilation (NIV) is a well-established, relatively new form of ventilation which improves sleep quality or gas exchange in some patients with chronic hypoventilatory disorders. Although sleep may be disrupted due to discomfort from the mask or air leaking during NIV use; intermittent use of NIV may result in better sleep quality between NIV sessions. The effects of NIV on sleep in the acute care setting have not yet been studied.

The purpose of the study is to describe the sleep architecture of a cohort of critically-ill patients using NIV, comparing findings to a reference group of patients using (IMV).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To define sleep characteristics in critically-ill patients receiving mechanical ventilation in medical ICU and coronary care unit (CCU)

    Measured: During 24-hour monitorization period (after recruitment into the study)

Secondary outcomes (4)
  1. To compare total sleep time and differences in sleep architecture including time spent in different sleep stages and arousals in critically-ill patients receiving mechanical ventilation in medical ICU and CCU

    Measured: During 24-hour monitorization

  2. To determine sleep patterns during NIV use, correlating sleep with periods of use and air leaking

    Measured: During 24-hour monitorization

  3. To monitor environmental factors including noise, light and patient care activities, and to associate these with sleep patterns

    Measured: During 24-hour monitorization

  4. To assess associations of severity of illness and sedation usage with sleep patterns

    Measured: During 24-hour monitorization period

Questions about this trial

What is this clinical trial studying?

An observational study of Respiratory Insufficiency and Respiration, Artificial, run by Tufts Medical Center at 1 site in United States.

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 7 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 6 Aug 2019. 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 United States. 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?

To define sleep characteristics in critically-ill patients receiving mechanical ventilation in medical ICU and coronary care unit (CCU) (time frame: During 24-hour monitorization period (after recruitment into the study)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 6 Aug 2019.
