About this study

The World Health Organization (WHO) has proposed the use of 80% high-dose inhalation oxygen (FiO2) during surgery to reduce postoperative infection in adult patients undergoing general anesthesia. However, high-dose inhaled oxygen increases the risk of oxygen toxicity by increasing reactive oxygen species, and according to a recent research, hyperoxia in the ICU is one of the causes of mortality. In patients with general anesthesia requiring intubation, high-dose inhaled oxygen was associated with postoperative pulmonary complications in a dose-proportional manner and was significantly associated with mortality within 30 days after surgery. Therefore, it is necessary to study the optimum oxygen concentration during surgery to reduce postoperative pulmonary complications in general anesthesia patients who require intubation. Esophagectomy for esophageal cancer still has higher morbidity and mortality rates than other common procedures. There are several factors such as aneurysmal leakage, esophageal substitute necrosis, cardiac complications, and pulmonary complications. Pulmonary complications have been reported to be a very important factor. Therefore, various methods have been proposed to reduce pulmonary complications after esophageal cancer surgery. One of them is minimally invasive surgery. However, even in the case of a thoracoscopic operation using a robot, one lung ventilation is inevitable for securing the visual field during surgery, and hypoxia and hyperoxia are known to be associated with postoperative acute lung injury. Therefore, in order to reduce postoperative pulmonary complications in the esophagectomy using robots, it is necessary to study the optimum oxygen concentration during surgery. The recently developed oxygen reserve index (ORI) uses a non-invasive sensor attached to the finger, similar to pulse oximetry, to detect persistent hyperoxia of more than 100 mmHg and less than 200 mmHg. Therefore, if the oxygen reserve index is used for robotic esophagectomy, which requires one lung ventilation, the degree of oxygenation of the patient can be monitored continuously and accurately. The authors will measure the oxygen reserve index in robotic esophagectomy, and analyze the correlation between oxygen reserve index and postoperative pulmonary complications. Furthermore, the cut-off value of the oxygen reserve index, which can reduce pulmonary complications, will be calculated.

Questions about this trial

What is this clinical trial studying?

An observational study of Endotracheal Intubation and Robotic Esophagectomy, run by Yonsei University at 1 site in South Korea.

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 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: status not confirmed, as of the sponsor's last update on 15 Jun 2022. 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 South Korea. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact So Yeon Kim, MD (82-2-2228-2429, KIMSY326@yuhs.ac), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The value of oxygen reserve index during anesthesia (time frame: Participants will followed until discharge (within about 2 months after surgery).). 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 15 Jun 2022.
