Trial summary

This study evaluates the omission of incentive spirometry use following bariatric surgery. Half of participants will receive an incentive spirometer while the other half will not. Oxygen saturation and pulmonary complications after surgery will be measured to examine the effectiveness of incentive spirometry. Read more about this study

About this study

This study evaluates the omission of incentive spirometry use following bariatric surgery. Half of participants will receive an incentive spirometer while the other half will not. Oxygen saturation and pulmonary complications after surgery will be measured to examine the effectiveness of incentive spirometry.

Read the detailed description

Incentive spirometry is speculated to improve pulmonary function in the postoperative period, though data to support this is lacking. Patients undergoing bariatric surgery are at increased risk for pulmonary compromise as they are obese and undergoing foregut surgery.

This study aims to examine the effect of incentive spirometry after bariatric surgery by performing a prospective randomized trial. Subjects will be randomized to either receive an incentive spirometer or not. The primary outcome measure of oxygen saturation off of supplemental oxygen will be taken preoperatively and at 6,12, and 24 hours postoperatively. Secondary outcome measures include rate of pulmonary complications, and time to wean off of supplemental oxygen.

What participants receive

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

  • Incentive spirometerDevice

    Also called Control

    Incentive spirometer is provided to the patient, this is the current standard of care, and is the control arm.

  • No incentive spirometerDevice

    Also called Study

    No incentive spirometer is provided to the patient, this is the study arm.

What is being measured

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

  1. Hypoxia 6 Hours Postoperative

    Number of subjects with pulse oximetry reading of < 92% with subject off of supplemental oxygen for 5 minutes with head of bed at 30°, 6 hours postoperative.

    Measured: 6 hours postoperative

  2. Hypoxia 12 Hours Postoperative

    Number of subjects with pulse oximetry reading of < 92% with subject off of supplemental oxygen for 5 minutes with head of bed at 30°, 12 hours postoperative.

    Measured: 12 hours postoperative

  3. Hypoxia 24 Hours Postoperative

    Number of subjects with pulse oximetry reading of < 92% with subject off of supplemental oxygen for 5 minutes with head of bed at 30°, 24 hours postoperative.

    Measured: 24 hours postoperative

Secondary outcomes (1)
  1. Postoperative Respiratory Complication

    atelectasis found on chest imaging, pneumonia, or re intubation

    Measured: entire inpatient say, usually 1 to 7 days

Questions about this trial

What is this clinical trial studying?

A study testing Incentive spirometer and No incentive spirometer in people with Obesity, Morbid and Complications of Bariatric Procedures, run by Lahey Clinic 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 1 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 25 Aug 2016. 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?

Yes. Results are posted in the registry (first posted 25 Aug 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?

Hypoxia 6 Hours Postoperative (time frame: 6 hours postoperative). The study lists 3 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 NCT02431455, which also lists 1 linked publication.

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 25 Aug 2016.
