Recruiting
Research Sponsored by Beth Israel Deaconess Medical Center
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
* Elective surgery with general anesthesia and endotracheal intubation
Be older than 18 years old
Timeline
Screening 3 weeks
Treatment Varies
Follow Up the cov is measured at six points: pre-induction, post-intubation, pre-washout, pre-extubation, 1 min post-extubation, and 60 min post-extubation in the pacu. the primary outcome is the difference between pre-induction and 1 min post-extubation.

No Placebo-Only Group

Summary

This trial aims to study whether using a lower oxygen concentration (70% compared to 100%) before removing a breathing tube reduces the risk of lung tissue collapse (atelectasis) in patients under anesthesia

Who is the study for?
This trial is for adults over 18 who are having elective surgery with general anesthesia and endotracheal intubation, lasting between 1-5 hours. They must consent to participate in the study.
What is being tested?
The study tests if using a lower oxygen concentration (70%) before removing a patient's breathing tube reduces lung collapse compared to the standard high oxygen level (100%). Patients are randomly assigned to one of these two approaches.
What are the potential side effects?
Potential side effects may include difficulty breathing or low blood oxygen levels after extubation. The risk of re-intubation or needing non-invasive ventilation post-surgery might also be affected.
