McGrath Series 5 videolaryngoscope vs Airtraq DL videolaryngoscope for double-lumen tube intubation

Abstract

Background:Many studies have shown Airtraq videolaryngoscope provided faster tracheal intubation and a higher success rate than other videolaryngoscopes. Recently, different types of videolaryngoscopes have been reported for use in double-lumen tube (DLT) intubation. However, the advantages and disadvantages between them remain undetermined for DLT intubation. In this study, we compared the Airtraq DL videolaryngoscope with the McGrath Series 5 videolaryngoscope for DLT intubation by experienced anesthesiologists.Methods:Ninety patients with expected normal airways were randomly allocated to either the Airtraq or McGrath group. The primary outcome was DLT intubation time. The secondary outcomes were glottic view, success rate, subjective ease of intubation (100-mm visual analog scale, 0 = easy; 100 = difficult), incidence of DLT malposition, and postoperative intubation-related complication.Results:The airway characteristics were comparable between the 2 groups. Cormack and Lehane grades significantly improved with the use of the McGrath and Airtraq videolaryngoscopes, compared with the Macintosh laryngoscope. The intubation success rate on the first attempt was 93% in the Airtraq group and 95% in the McGrath group (P > 0.05). The intubation time in the McGrath group is longer than that in the Airtraq group (39.9 [9.1]s vs 28.6 [13.6]s, P < 0.05). But intubation difficulty score, the incidence of DLT malposition and intubation-related complication were comparable between groups (P > 0.05).Conclusions:When using videolaryngoscopes for DLT intubation, the Airtraq DL is superior to the McGrath Series 5 in intubation time, but it does not decrease intubation difficulty.

Different classes of videoscopes and direct laryngoscopes for double-lumen tube intubation in thoracic surgery: A systematic review and network meta-analysis

“…Not only SV but also the other videoscopes showed better success rates than Mc. The results were consistent with the previous studies on DLT intubation [ 1 , 8 , 17 , 18 , 20 , 25 , 26 , 29 , 30 , 32 , 36 , 37 ]. However, the best choices differed according to the indicators.…”

“…Four groups of devices from 14 studies were available for the analysis [ 7 , 18 , 20 , 25 , 27 – 30 , 32 , 33 , 35 , 37 – 39 ]. Eligible comparisons in the NMA are shown in Figs 3D and 4D .…”

“…For blinding, given that different devices were used in almost all RCT studies, all studies (100%) were evaluated as high risk in blinding of participants and personnel to the intervention of the studies (performance bias). Eight studies (35%) that reported blinding of the outcome assessors were assessed as having unclear risk of bias [7,8,25,[27][28][29][30][31], and the other…”

“…Success rate of the first attempt intubation of DLT. Four groups of devices from 21 studies were available for the analysis [1,7,8,17,18,20,[24][25][26][27][28][29][30][31][32][33][35][36][37][38][39]. Eligible comparisons in the NMA are shown in Figs 3A and 4A.…”
