Video-assisted versus macintosh direct laryngoscopy for intubation of obese patients: a meta-analysis of randomized controlled trials

INTRODUCTION: We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) to compare the usefulness video-assisted (VL) approaches with Macintosh direct laryngoscope for endotracheal intubation obese patients. MATERIAL AND METHODS: Studies were obtained via search SCOPUS, Medline, Web Science, CINAHL, Cochrane Central databases. The polled relative risks (RRs) odds ratios (ODs) or standard mean differences (SMD) 95% confidence intervals (CIs) calculated random–effects model. Subgroup analyses evaluate influence VL types on association. RESULTS: First attempt success rate in DL group varied amounted 94.7% vs 89.5% respectively (OR = 2.04; CI: 1.21–3.42; p 0.007) overall was 99.0% 97.5% 2.20; 0.45–10.67; 0.33). Intubation time which 48.0 ± 37.7 48.4 37.5 seconds (SMD 0.14; –0.33–0.61; 0.56). Cormack-Lehane 1 2 grade during using observed 95.9% cases statistically significantly higher than case laryngoscopy (79.6%; OR 6.68; 3.32–13.42; < 0.001). CONCLUSIONS: Our suggests that may be superior conventional an patient population due first–attempt rate, better glottis visibility, lower intubation-related injuries.
