U.S., Dec. 20 -- ClinicalTrials.gov registry received information related to the study (NCT07293286) titled 'Effect of Different Oxygen Concentrations Before Extubation After General Anesthesia on Hypoxemia After Extubation in Post-anesthesia Care Unit' on Nov. 18.
Brief Summary: Before extubation during the anesthesia recovery period, 100% oxygen is routinely inhaled to increase the oxygen reserves, maximizing the time window for anesthesiologists to adjust strategies when they encounter hypoxemia after extubation.
However, even inhaling a short period of pure oxygen can cause absorptive atelectasis, and may even impair the effectiveness of intraoperative protective ventilation measures continuing to post-operative period. The purpose of...
