About this study

Official title: Use of Mechanical Insufflator-exsufflator in Patients After Video-assisted Thoracoscopic Operations With One-lung Ventilation on Postoperative Pulmonary Complications: a Randomized Trial

Postoperative pulmonary complications (PPC) are a common problem in patients undergoing surgery using one-lung invasive ventilation. Major pulmonary complications such as atelectasis, bronchospasm, and pneumonia can lead to respiratory failure. PPC are the main cause of mortality in the postoperative period in patients after thoracic surgery. The study aimed to compare the effectiveness of using a mechanical insufflator-exsufflator after video-assisted thoracoscopic surgery using one-lung ventilation to reduce postoperative pulmonary complications as compared to standard therapy.

Read the detailed description

Postoperative pulmonary complications (PPC) are a common problem in patients undergoing surgery using one-lung invasive ventilation. Major pulmonary complications such as atelectasis, bronchospasm, and pneumonia can lead to respiratory failure. PPC are the main cause of mortality in the postoperative period in patients after thoracic surgery. The incidence of PPC ranges from 5% to 80%. Patients undergoing thoracic surgery are usually at high risk. Most often these are elderly people with concomitant diseases. Most of these patients are smokers, have occupational exposures, and are therefore at even greater risk of developing pulmonary complications. Part of their problem is due to poor baseline pulmonary function. Improving mucus production in the postoperative period using a mechanical insufflator-exsufflator may help reduce the incidence of complications.

What participants receive

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

  • Mechanical insufflator-exsufflatorDevice

    In the active comparator group a mechanical insufflator-exsufflator will be used in the postoperative period 6 and 24 hours after extubation as follows ("coughing maneuver"): application of inspiratory pressure of 40-70 cm of water (the minimum value to achieve a peak cough flow of 300 l/min) for 2 seconds with the subsequent creation of an expiratory vacuum of -40 cm of water within 2 seconds. During inhalation and exhalation, the patient will apply oscillations with a frequency of 10 Hz and an amplitude of 10 cm of water. A series of 10 such maneuvers will be used, with a pause of a few seconds to ensure patient comfort. The "coughing" maneuver will be performed through an oronasal mask tightly pressed to the face.

    Measured: On 48 hour after operation

  5. The volume of atelectasis on chest computed tomography 36-48 hours after tracheal extubation

    The volume of atelectasis on chest computed tomography 36-48 hours after tracheal extubation

    Measured: On 36-48 hour after operation

Secondary outcomes (5)
  1. Pain according to visual analogue scale (VAS) of pain 6 hours after tracheal extubation

Questions about this trial

What is this clinical trial studying?

A study testing Mechanical insufflator-exsufflator in people with Thoracic Diseases, run by I.M. Sechenov First Moscow State Medical University at 1 site in Russia.

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 4 inclusion and 9 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 May 2025. 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 Russia. 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 oxygen saturation level (SpO2) when breathing atmospheric air 6 hours after tracheal extubation (time frame: On 6 hour after operation). The study lists 5 primary outcomes in all. 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 2 May 2025.
