ABSTRACT=<sec><title>Purpose</title><p>This study was performed to assess the postoperative recovery outcomes in obese patients undergoing general anesthesia.</p></sec><sec><title>Methods</title><p>The eligible studies were identified from PubMed, EmBase, and the Cochrane library until December 2020. The standard mean differences (SMDs) with 95% confidence intervals (CIs) were used to calculate the role of desflurane, sevoflurane, and propofol on recovery outcomes, and the analyses using the random-effects model.</p></sec><sec><title>Results</title><p>Eleven randomized controlled trials involving 713 obese patients undergoing general anesthesia were selected for final meta-analysis. We noted desflurane was associated with a shorter time to eye-opening than sevoflurane (SMD: −0.86; 95% CI, −1.43 to −0.28; <italic>P</italic> = 0.003). The use of desflurane with shorter time to extubation as compared with propofol (SMD: −1.13; 95% CI, −1.52 to −0.73; <italic>P</italic> &lt; 0.001) or sevoflurane (SMD: −1.19; 95% CI, −2.15 to −0.22; <italic>P</italic> = 0.016), while sevoflurane was associated with longer time to extubation as compared with propofol (SMD: 1.47; 95% CI, 1.03 to 1.91; <italic>P</italic> &lt; 0.001). Desflurane were associated with shorter time to stating name as compared with propofol (SMD: −1.40; 95% CI, −2.32 to −0.48; <italic>P</italic> = 0.003) or sevoflurane (SMD: −2.09; 95% CI, −3.33 to −0.85; <italic>P</italic> = 0.001). In addition, desflurane was associated with a longer time for orientation to place as compared with propofol (SMD: 0.65; 95% CI, 0.22 to 1.07; <italic>P</italic> = 0.003), while desflurane with shorter time for orientation to place as compared with sevoflurane (SMD: −0.88; 95% CI, −1.46 to −0.30; <italic>P</italic> = 0.003).</p></sec><sec><title>Conclusions</title><p>The use of desflurane could provide better recovery outcomes in obese patients undergoing general anesthesia. Further large-scale trials should be comparison the long-term effectiveness of various anesthetics.</p></sec>
