IntroductionBougies and stylets are widely acknowledged as effective tools for managing endotracheal intubation, uncertainties persist regarding the comparative efficacy and safety of bougie versus stylet approaches in endotracheal intubation.Evidence AcquisitionA comprehensive electronic search was conducted on the Cochrane Library, PubMed, and Embase databases from inception to December 9, 2023, using the keywords "endotracheal intubation," "bougie," and "stylet." This meta-analysis aims to evaluate and compare the performance of bougies and stylets in patients undergoing endotracheal intubation.Evidence SynthesisA total of 12 articles, encompassing 2534 participants, were included in this meta-analysis. The bougie approach did not exhibit superiority in first-attempt success rate (83.6% vs. 81.7%; OR, 1.06, 95% CI, 0.49 to 2.29; P=0.89) and total intubation success rate (99.3% vs. 97.6%; OR, 2.32, 95% CI, 0.44 to 12.34; P=0.32, I2>50%, P<0.001). However, in patients with difficult airways, the bougie approach demonstrated a superior first-attempt success rate compared to the stylet approach (93.8% vs. 76.4%; OR, 5.25, 95% CI, 2.74 to 10.05; P<0.001). There was no significant difference in complications between the bougie and stylet approaches (P>0.05).ConclusionsFor patients with difficult airway characteristics, our recommendation is to perform endotracheal intubation (ETI) using the bougie approach over the stylet approach, as it has been associated with a better first-attempt success rate. Notably, the advantages of using a bougie may be less pronounced for patients without signs of a difficult airway.
