Trial summary

Patients with chest trauma undergo ultrasound to detect a collapsed lung. Two techniques have been described. A single view for each hemi-thorax, and multiple views for each hemithorax. The investigators are comparing these two techniques in a randomized prospective trial. Read more about this study

About this study

Patients with chest trauma undergo ultrasound to detect a collapsed lung. Two techniques have been described. A single view for each hemi-thorax, and multiple views for each hemithorax. The investigators are comparing these two techniques in a randomized prospective trial.

Read the detailed description

This is a randomized, prospective blinded study on trauma patients arriving to an emergency department.

Study Setting and Population This study will be conducted on the University Campus of the University of Massachusetts Medical Center, which is an urban academic emergency department that sees 80,000 patients annually and has a dedicated Level I trauma service that is staffed by trauma surgery and emergency medicine. Adult patients with acute traumatic injury who are undergoing a CT scan of the chest are eligible for enrollment.

Study Protocol Trauma patients are enrolled as they arrived to the emergency department. The investigators will include any trauma patient aged 18 and over. The investigtors will exclude any patient who was too unstable and required clinical care that prevented performing a chest wall ultrasound, patients with a chest tube in place prior to arrival, pregnant women, and prisoners. Imaging decisions on trauma patients will be made early on in their evaluation. The patient will be assigned using a pre-determined randomization scheme to a single view or four views of each hemi-thorax prior to any imaging being done. Ultrasounds will be performed and interpreted by credentialed physicians using a 7.5Mhz linear array transducer on a portable ultrasound machine (Zonare z.one ultra) with digital clips recorded for later review. When the investigators obtain a single view of each hemi-thorax, the probe will be placed in a longitudinal orientation on the midclavicular line in the third intercostal space. When the investigators obtain four views of each hemi-thorax, the first image location will be the same as in the single view and then the probe will be moved inferiorly and laterally to obtain the additional three images. Immediately following the ultrasound examination, the patient will be transported to the CT scanner for further imaging.

The goal of this study is to determine if a single view of each hemi-thorax can identify a pneumothorax or if additional images should be included. The primary study endpoint is the presence of a pneumothorax on ultrasound.

Questions about this trial

What is this clinical trial studying?

A study testing Ultrasound Imaging in people with Pneumothorax, run by University of Massachusetts, Worcester.

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 1 inclusion and 5 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 7 Nov 2016. Status can change between updates, so confirm with the study contact before making plans.

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?

Yes. Results are posted in the registry (first posted 7 Nov 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Pneumothorax (Positive or Negative) (time frame: up to 20 minutes). 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 7 Nov 2016.
