Double-lumen intubation is more difficult than single-lumen tracheal intubation. Videolaryngoscopes have many advantages in airway management. However, the advantages of videolaryngoscopy for intubation with a double-lumen tube remain controversial compared with traditional Macintosh laryngoscopy. In this study, we searched MEDLINE, Embase, Cochrane Library and the Web of Science for randomised controlled trials comparing videolaryngoscopy with Macintosh laryngoscopy for double-lumen tube intubation. We found that videolaryngoscopy provided a higher success rate at first attempt for double-lumen tube intubation, with an odds ratio (95%CI) of 2.77 (1.92-4.00) (12 studies, 1215 patients, moderate-quality evidence, p < 0.00001), as well as a lower incidence of oral, mucosal or dental injuries during double-lumen tube intubation, odds ratio (95%CI) 0.36 (0.15-0.85) (11 studies, 1145 patients, low-quality evidence, p = 0.02), and for postoperative sore throat, odds ratio (95%CI) 0.54 (0.36-0.81) (7 studies, 561 patients, moderate-quality evidence, p = 0.003), compared with Macintosh laryngoscopy. There were no significant differences in intubation time, with a standardised mean difference (95%CI) of -0.10 (-0.62 to 0.42) (14 studies, 1310 patients, very low-quality evidence, p = 0.71); and the incidence of postoperative voice change, odds ratio (95%CI) 0.53 (0.21-1.31) (7 studies, 535 patients, low-quality evidence, p = 0.17). Videolaryngoscopy led to a higher incidence of malpositioned double-lumen tube, with an odds ratio (95%CI) of 2.23 (1.10-4.52) (six studies, 487 patients, moderate-quality evidence, p = 0.03).

Because it is difficult to identify the location of the DLT in the lateral position when using a standard laryngoscope, we used a McGRATH MAC ® laryngoscope to confirm the precise location.…”

Multidetector-row computed tomography (MDCT) allows visualization and measurement of anatomical structures. Because we seek a reliable method by which we can predict displacement of the double lumen endotracheal tube (DLT) in patients when supine to lateral repositioning is required during surgery, we performed MDCT preoperatively for 84 patients scheduled for elective respiratory surgery with a left DLT. We obtained 3D MDCT reconstruction images of each patient's bronchus and then measured the distance between the vocal cords and the bifurcation of the left upper lobe bronchus. We defined this distance as the MDCT-derived appropriate depth of placement (ADP). We used two other methods to determine ADP: the standard measurement method based on the patient's height and the chest X-ray method based on the distance from the superior border of the sixth cervical vertebra to the tracheal bifurcation. During surgery, we evaluated the actual change in ADP when the patient was moved from the supine to the lateral position. We then compared the actual ADP with the MDCT-derived ADP to assess whether the MDCT-derived ADP predicts DLT displacement during the patient repositioning.We found that during surgery, the DLT had slipped out of position in 31 (44%) patients, had moved too deeply in 6 (7%), and had not changed in 41 (49%). Multiple logistic regression analysis showed that the MDCT-derived ADP was significantly associated with DLT displacement upon patient repositioning (odds ratio, 2.9; 95% CI, 1.5-5.6; p=0.002), whereas standard ADP and chest X-ray-derived ADP were not associated with DLT displacement. We postulate that various factors, such as extension or flexion of the neck and size of the DLT, may contribute the DLT displacement during patient repositioning.We believe, on the basis of our study data, that ADP derived from pre-operative MDCT will be useful for predicting DLT displacement when patients are moved from the supine to lateral position during surgery.

“…Rocuronium was administered as a muscle relaxant. Laryngoscopy was performed with the McGRATH MAC [1], and the i-gel was gently placed so as to avoid collisions with the glottis. Sealing pressure was sufficient (N 30 cm H 2 O), and mechanical ventilation was performed uneventfully.…”
