Popis: Background: Controversy exists regarding the effects of a high versus a low intraoperative fraction of inspired oxygen (FiO 2) in adults undergoing general anesthesia. This systematic review and meta-analysis investigated the effect of a high versus a low FiO 2 on postoperative outcomes. Methods: PubMed and Embase were searched on March 22, 2022 for randomized clinical trials investigating the effect of different FiO 2 levels in adults undergoing general anesthesia for non-cardiac surgery. Two investigators independently reviewed studies for relevance, extracted data, and assessed risk of bias. Meta-analyses were performed for relevant outcomes, and potential effect measure modification was assessed in subgroup analyses and meta-regression. The evidence certainty was evaluated using GRADE. Results: This review included 25 original trials investigating the effect of a high (mostly 80%) versus a low (mostly 30%) FiO 2. Risk of bias was intermediate for all trials. A high FiO 2 did not result in a significant reduction in surgical site infections (OR: 0.91, 95% CI 0.81–1.02 [p =.10]). No effect was found for all other included outcomes, including mortality (OR = 1.27, 95% CI: 0.90–1.79 [p =.18]) and hospital length of stay (mean difference = 0.03 days, 95% CI −0.25 to 0.30 [p =.84). Results from subgroup analyses and meta-regression did not identify any clear effect modifiers across outcomes. The certainty of evidence (GRADE) was rated as low for most outcomes. Conclusions: In adults undergoing general anesthesia for non-cardiac surgery, a high FiO 2 did not improve outcomes including surgical site infections, length of stay, or mortality. However, the certainty of the evidence was assessed as low.
