Abstract

Predicting and managing the difficult airway is a lifesaving and vital basic task for the anesthetist. Current guidelines of all important societies include thyromental distance (TMD, "Patil") as a possible predictor for a difficult airway and includes two important aspects for airway management: the mandibular space and the flexibility of the cervical spine. We evaluated knowledge and execution regarding TMD for predicting a difficult airway on participants at the Euroanaesthesia (ESA) congress and German Anaesthesia Congress (DAC) in 2014. Our evaluation consisted of a theoretical part with questions regarding general knowledge and a practical evaluation with anesthetists performing on a human airway model. Practical evaluations were performed separately from other participants. During the DAC 245 (ESA 230) physicians participated, of which 64% were male (ESA 58%). At the DAC 182 (74.3%) and ESA 82 (35.6%) participants knew about Patil/TMD. Its use as a predictive score for a difficult airway was known by 122 (49.8%; DAC) and 79 (34.4%; ESA) participants. The correct definition for intubation was given by 45 (25.7%) at the DAC and 56 (24.3%) at ESA. Only 40-41% of the participants measured the correct distance for TMD. Only 6.1-6.5% completed both the theoretical and practical parts correctly. As non-invasive TMD includes two different aspects of patient airways and is part of current guidelines, education and training must be extended to assure adequate evaluation in the future.

Abstract

Several studies have shown that video laryngoscopy enhances the laryngeal view in patients with apparently normal and anticipated difficult airways. The utility of the novel, portable, battery-powered C-MAC video laryngoscope is unproven, but its design makes it potentially useful for emergency situations. We hypothesized that, in patients with a simulated difficult airway created by means of a rigid cervical immobilization collar, the rate of glottic views considered "failed" under direct laryngoscopy could be significantly reduced with the C-MAC video laryngoscope.Following power analysis and ethical approval, 43 adults undergoing surgery under general anesthesia were studied. First, direct laryngoscopy was performed with the naked eye with and without applying external laryngeal pressure (BURP maneuver). The best-obtained view was graded by the laryngoscopist without looking at the video monitor. A second anesthesiologist, who was blinded to the laryngeal view obtained under direct laryngoscopy, graded the laryngeal view on the video monitor. A difficult airway was then created and the laryngoscopy sequence repeated. Endotracheal intubation was then attempted under video-aided visualization.In patients with a normal airway, the glottic view was considered as "good" in the vast majority of patients (40-43/43; 93-100%) regardless of the laryngoscopy technique used. When a difficult airway was created, the glottic view was graded as "failed" in 30/43 (70%) and 16/43 (37%) of patients under direct laryngoscopy without and with the BURP maneuver, respectively (P=0.0047). Using video laryngoscopy, significantly fewer laryngoscopic views were graded as "failed" without (14%, P0.0001) and with the BURP maneuver (5%, P=0.0003) compared to direct laryngoscopy. Endotracheal tube placement was successful in 88% of patients with a difficult airway.The C-MAC video laryngoscope effectively enhanced the laryngeal view in patients with limited inter-incisor distance and eliminated cervical spine clearance. However, endotracheal tube placement failed in 5/43 patients despite a mostly good laryngeal view.
