“…Although videolaryngoscopes improve the laryngeal view and have an easy learning curve, no advantages over Macintosh laryngoscopy in terms of the C-spine motion and intubation procedure time have been observed (13)(14)(15)(16)(17). Consistent with these studies, our study revealed that the C-MAC videolaryngoscope has no superiority over Macintosh laryngoscope regarding the C-spine motion.…”

Objective: Endotracheal intubation should be performed with care when cervical spine (C-spine) injury is suspected. The aim of this study was to evaluate the movement of the C-spine using fluoroscopy during intubation with Laryngeal Mask Airway (LMA) CTrach, C-MAC videolaryngoscope and Macintosh laryngoscope. Methods: This was a single-centre, prospective, observational, controlled trial. In total, 22 surgical patients aged 18-65 years planned to undergo operation under general anaesthesia, were enrolled. X-ray images of the C-spine were obtained using fluoroscopy with the patients' head in a neutral position. All patients underwent laryngoscopy using a Macintosh blade, LMA CTrach and C-MAC videolaryngoscope, and fluoroscopic images of the C-spine were obtained. All the patients were intubated at the last laryngoscopy simulation (using the C-MAC). The atlanto-occipital distance (AOD) and angles between C 0 C 1 , C 0 C 2 , C 0 C 3 , C 0 C 4 , C 1 C 2 and C 2 C 3 lines were measured and compared between each device. Results: The mean AOD was measured as 20.4 mm in a neutral position, which decreased to 13.1, 17.2 and 12.3 mm after the insertion of the Macintosh laryngoscope, LMA CTrach and C-MAC videolaryngoscope, respectively. The differences were significant (p<0.001). Moreover, significant difference was noted in C 0 C 2 , C 0 C 3 and C 1 C 2 angles with the insertion of the three devices (p<0.001). The LMA CTrach resulted in significantly lesser C-spine movements in C 0 C 2 , C 0 C 3 and C 0 C 4 angles compared to the Macintosh laryngoscope and C-MAC videolaryngoscope (p<0.001). Conclusion:The LMA CTrach resulted in lesser C-spine movements compared to Macintosh laryngoscope and C-MAC videolaryngoscope. In case of the C-spine injury, LMA CTrach may be preferred and may cause fewer traumas during endotracheal intubation. Keywords: Cervical spine motion, LMA C Trach, videolaryngoscopy, fluoroscopy Amaç: Servikal omurga hasarından şüphelenildiğinde endotrakeal entübasyon dikkatli yapılmalıdır. Bu çalışmanın amacı LMA (Laryngeal Mask Airway) CTrach, C-MAC Videolaringoskop ve Macintosh Laringoskop ile entübasyon sırasında floroskopi ile servikal omurga hareketini değerlendirmektir. Yöntemler: Bu tek merkezli, prospektif, gözlemsel kontrollü bir çalışmaydı. Çalışmaya 18-65 yaşları arasında genel anestezi altında operasyon uygulanan 22 hasta dahil edildi. Endotrakeal entübas-yondan önce, hastanın başı nötr konumda iken servikal omurga floroskopi görüntüleri elde edildi. Tüm hastalarda standart Macintosh laringoskop, LMA CTrach ve C-MAC Videolaringoskop kullanıldı. Laringoskopi simülasyonları sırasında servikal omurgadaki değişikliklerin floroskopik görüntüleri elde edildi. Tüm hastalar son laringoskopi sırasında C-MAC kullanılarak entübe edildi. Floroskopi görüntüleri üzerinde C 0 C 1 , C 0 C 2 , C 0 C 3 , C 0 C 4 , C 1 C 2 ve C 2 C 3 arasındaki Atlantooksipital mesafeler ve açılar ölçüldü ve aradaki farklar cihazlar arasında karşılaştırıldı. Bulgular: Ortalama Atlantooksipital mesafe, nötral pozisyonda 20,4 mm ölçül...

“…The McL blade has been the standard instrument of choice for placing DLTs for several decades. The McL blade displaces a greater volume of soft tissue, and its angle appears to strike the best balance between achieving an adequate direct laryngeal view and providing the necessary space for DLT trajectory control in most airways [11]. The suboptimal visualization with the McL often leads to difficult DLT placement.…”

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.
