Key Takeaway
Note extreme heterogeneity limits certainty of trend toward shorter intubation time with video double-lumen tubes.
This meta-analysis examined the impact of video double-lumen tubes compared to standard double-lumen tubes on intubation time within a thoracic surgery setting. The analysis included data from 1,332 patients across multiple studies. The primary outcome assessed was the duration of intubation required to secure the airway.
The synthesized results demonstrated a trend toward shorter intubation time in the video double-lumen tube group. The mean difference was calculated at -102.68 seconds, with a 95% confidence interval ranging from -123.71 to -81.66 seconds. No specific adverse events or discontinuations were reported in the source data.
A critical limitation identified by the authors is extreme and unexplained between-study heterogeneity, quantified as an I2 value of 99%. This high level of variability suggests that the results may not be consistent across all clinical contexts. Consequently, the practice relevance of these findings remains uncertain due to the lack of reported funding information and the inability to establish causality.

BackgroundDouble-lumen tube (DLT) is generally regarded as the gold standard for one-lung ventilation during thoracic surgery. Compared with DLT, video double-lumen tube (VDLT) has an integrated camera, allowing continuous visualization of its position in the trachea. However, the clinical efficacy of VDLT for one-lung ventilation in thoracic surgery is unclear. This meta-analysis aims to evaluate the clinical efficacy of VDLT for one-lung ventilation in thoracic surgery.MethodsThe PubMed, EMBASE, Web of Science, the Cochrane Library, CNKI, WanFang, and CBM databases were searched for relevant studies from inception to July 2025. This meta-analysis used RevMan and Stata software to implement statistical analysis. The primary outcome was the intubation time. Sensitivity analysis and Egger’s test were performed to evaluate the stability of the results and the publication bias.ResultsEighteen studies involving 1,332 patients were included. For the primary outcome intubation time, extreme and unexplained between-study heterogeneity was observed (I2 = 99%). A random-effects model was applied, and the pooled result suggested a trend toward shorter intubation time in the VDLT group (MD = −102.68 [95% CI: −123.71 to −81.66], p
