About this study
Official title: Ventilation Strategies Impact on Oxygenation and Postoperative Pulmonary Complications in Lung Surgery Patients: a Prospective, Randomized, Triple-Blind Trial
The purpose of this clinical trial was to understand the effects of variable tidal volume ventilation (V-VCV), pressure-regulated volume-controlled ventilation (PRVC), conventional volume-controlled ventilation (C-VCV), pressure-controlled ventilation (PCV), and open surgery (Open Surgery). controlled ventilation (C-VCV), pressure-regulated volume-controlled ventilation (PRVC), conventional volume-controlled ventilation (C-VCV), and pressure-controlled ventilation (PCV) for open surgery, video-assisted thoracoscopic surgery, and segmental lung resection. VATS), segmentectomy (Segmentectomy), lobectomy (Lobectomy), and pneumonectomy (Pneumonectomy) on oxygen saturation and pulmonary complications, and length of hospitalization.
The main question it aims to answer is: variable tidal volume ventilation (V-VCV), pressure-regulated volume-controlled ventilation (PRVC), conventional volume-controlled ventilation (C-VCV), and pressure-controlled ventilation (PCV).Does it decrease patient oxygen saturation, and does it increase pulmonary complications, length of hospitalization? Researchers compared variable tidal volume ventilation (V-VCV), pressure-regulated volume-controlled ventilation (PRVC), conventional volume-controlled ventilation (V-VCV), pressure-regulated volume-controlled ventilation (PRVC), conventional volume-controlled ventilation (C-VCV), and pressure-controlled ventilation (PCV) to compare them to see which mode of ventilation has the least physiologic disruption for the patient.

Questions about this trial
What is this clinical trial studying?
A study testing variable tidal volume ventilation (V-VCV) in people with Lung Surgery, run by Inner Mongolia Baogang Hospital at 1 site in China.
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 2 inclusion and 4 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: opening soon, as of the sponsor's last update on 3 Feb 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 China. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Xiaguang XG Duan, Master's degree (+86 13314720012, alonlord2023@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
oxygen saturation (time frame: One week postoperative). 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 3 Feb 2025.
