Search Strategy and Selection Criteria
This systematic review and meta-analysis was conducted in accordance with the protocol specified in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.14 We searched RCTs in the PubMed, Embase, and Cochrane databases from inception through January 30, 2017, to identify potentially relevant studies. Search terms included: “videotape recording” OR “video-laryngoscope” OR “video laryngoscopy” OR “video recording” OR “laryngoscopes” AND “critically ill” OR “intensive
Trial Identification and Characteristics
The literature search yielded 382 records through database searching, and five RCTs fulfilling inclusion criteria were eligible for final analysis.7, 8, 12, 13, 17 The overview of the study selection process is presented in Figure 1. The Cochrane risk of bias score varied across these studies (e-Figs 1 and 2). The main characteristics of included studies and predefined outcomes are shown in Tables 1 and 2, respectively, and the definitions of operator experience and first-pass success during
Discussion
In the current meta-analysis, we compared the use of VL with the DL technique in critically ill patients requiring EI. Despite better glottic visualization, use of VL did not increase the first-attempt success rate during EI. In addition, there were no differences between the VL and DL groups in terms of the secondary outcomes, such as time to intubation, difficult intubation, and mortality rate. Our results are in contrast with the findings of a previous meta-analysis,6 which showed that,
Conclusions
VL did not improve the first-pass success rate during EI in ICU patients compared with DL. These findings do not support routine use of VL during EI.
