. Evaluation of C-MAC PM® in combination with a standard Macintosh blade size 3 in direct and indirect laryngoscopy and D-Blade® in indirect laryngoscopy in a simulated difficult airway. Primary outcome was defined as the best view of the glottic structures. Secondary endpoints were subjective evaluation and assessment of the intubation process. . Prospective monocentric, observational study on 48 adult patients without predictors for difficult laryngoscopy/tracheal intubation undergoing orthopedic surgery. Every participant preoperatively received a cervical collar to simulate a difficult airway. Direct and indirect laryngoscopy w/o the BURP maneuver with a standard Macintosh blade and indirect laryngoscopy w/o the BURP maneuver using D-Blade® were performed to evaluate if blade geometry and the BURP maneuver improve the glottic view as measured by the Cormack-Lehane score. . Using a C-MAC PM® laryngoscope, D-Blade® yielded improved glottic views compared with the Macintosh blade used with either the direct or indirect technique. Changing from direct laryngoscopy using a Macintosh blade to indirect videolaryngoscopy using C-MAC PM® with D-Blade® improved the Cormack-Lehane score from IIb, III, or IV to I or II in 31 cases. . The combination of C-MAC PM® and D-Blade® significantly enhances the view of the glottis compared to direct laryngoscopy with a Macintosh blade in patients with a simulated difficult airway. . This trial is registered under number NCT03403946.
. 在模拟困难气道中，评估C-MAC PM®喉镜联合标准3号Macintosh叶片进行直接和间接喉镜检查以及D-Blade®喉镜进行间接喉镜检查的效果。主要结局定义为声门结构的最佳视野。次要终点为插管过程的主观评估。. 对48例接受骨科手术且无喉镜检查/气管插管困难预测因素的成年患者进行前瞻性单中心观察性研究。每位参与者术前佩戴颈托以模拟困难气道。使用标准Macintosh叶片在不进行BURP手法的情况下进行直接和间接喉镜检查，以及使用D-Blade®喉镜在不进行BURP手法的情况下进行间接喉镜检查，以评估叶片几何形状和BURP手法是否能改善由Cormack-Lehane评分衡量的声门视野。. 使用C-MAC PM®喉镜时，与直接或间接技术中使用的Macintosh叶片相比，D-Blade®能提供更好的声门视野。在31例患者中，从使用Macintosh叶片的直接喉镜检查改为使用C-MAC PM®和D-Blade®的间接视频喉镜检查后，Cormack-Lehane评分从IIb、III或IV级提高到I或II级。. 在模拟困难气道的患者中，与使用Macintosh叶片的直接喉镜检查相比，C-MAC PM®和D-Blade®的组合显著增强了声门视野。. 该试验已在编号NCT03403946下注册。
