About this study
Official title: Inhalational Versus Intravenous Anesthesia on Lung Injury After Major Surgery in Patients With Sepsis
This randomized controlled trial will compare the effects of intraoperative inhalational anesthesia versus intravenous anesthesia on postoperative lung injury in septic patients undergoing surgery. The primary goal is to determine if the choice of anesthetic technique influences the incidence or severity of this complication. Participants will be randomly assigned to one of the two anesthetic regimens during surgery. They will receive daily in-hospital assessments for lung injury and other outcomes and will be followed for clinical outcomes until 90 days after the procedure.
- Conditions
- Sepsis, Lung Injury
- Being tested
- Inhalation Anesthesia, intravenous anesthesia
- Medical subject headings
- Sepsis, Lung Injury
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Inhalation AnesthesiaDrug

intravenous anesthesiaDrug
The intravenous group will be maintained with continuous intravenous infusions of both ciprofol and remifentanil.

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.

What does the primary outcome measure?
Ventilator-free days at 7 days after surgery (time frame: From the surgery to the 7th day). 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 22 May 2026; AzTrials last refreshed its copy on 8 Nov 2026.
