Summary: A model based on intubation-related variables was developed to classify the difficulty of videolaryngoscopic tracheal intubation. The model was validated and found to have good discrimination ability in predicting difficult airway alerts after videolaryngoscopy, outperforming the Cormack-Lehane classification. The findings of this study provide a useful tool for assessing the probability of difficult airway management.

Summary: The head-elevated position, achieved by aligning the external auditory meatus and sternal notch in the horizontal plane, improves laryngeal visualization and ease of intubation in patients with simulated difficult airways.

Summary: In patients with difficult airways, there was no significant difference in the first-pass success rate of double-lumen tube (DLT) intubation between the GlideScope and C-MAC D-blade videolaryngoscopes. However, the C-MAC D-blade provided a better glottic view, easier and faster intubation, and lower incidence of postprocedure sore throat.

Summary: Management of the difficult airway is crucial as failure to establish an airway can be life-threatening. Advances in visualization techniques can be helpful, and difficult intubation can often be anticipated and prepared for.

Summary: This study compared videolaryngoscopes with direct laryngoscopes in simulated cardiopulmonary resuscitation scenarios. Videolaryngoscopes showed shorter intubation times in normal airway scenarios, with VividTrac outperforming in difficult airway scenarios. However, Macintosh laryngoscopes demonstrated better glottis views and less esophageal intubation.

Summary: This study evaluated the feasibility and safety of GlideScope(TM) videolaryngoscopes in patients with severely restricted mouth opening. The results showed that GlideScope(TM) successfully achieved tracheal intubation, with more difficulty in patients with an inter-incisor gap < 2.0 cm. The study concluded that GlideScope(TM) videolaryngoscopy is feasible and safe in patients with restricted mouth opening if given limitations are respected.

Summary: This study evaluates the value of Upper Lip Bite Test (ULBT) and Modified Mallampati Test (MMT) in predicting difficult intubation under direct laryngoscopy and finds that both tests have only poor to moderate discriminative power when used alone, and their combination does not improve the sensitivity in predicting difficult intubation.

Summary: Analysis of sonographic parameters revealed that the hyomental distance in the neutral position is the most reliable indicator for predicting a difficult airway.

Summary: This study demonstrates that using McGrath videolaryngoscopy improves first-pass tracheal intubation success in patients having elective surgery compared with direct laryngoscopy. Randomly allocating 2092 adult patients without predicted difficult airway, this multicentre randomized trial found that the first-pass success rate was higher in the McGrath group (94%) compared with the direct laryngoscopy group (82%).

Summary: This prospective study found that preoperative transnasal videoendoscopy (TVE) improves the prediction of difficult videolaryngoscopic intubation in adults with expected difficult airway management, especially when combined with the Simplified Airway Risk Index (SARI).

Summary: This study compares the predictive values of different tests for prediction of difficult intubation in obese patients and finds that thyromental height and upper lip bite test have the highest sensitivity in predicting difficult intubation.

Summary: The American Society of Anesthesiologists has developed a decision tree tool to assist anesthesiologists in managing difficult airways. The tool considers various factors such as the risk of difficulty with laryngoscopy and intubation, the need for facemask or supraglottic ventilation, the risk of gastric contents aspiration, and rapid oxyhemoglobin desaturation. It aims to improve communication and decision-making among anesthesiologists.

Summary: The study found that C-MAC Miller and McGrath MAC showed similar intubation timings, success rates, and intubation difficulty scores in neonates and infants, but the former provided superior glottic views.

Summary: This study aimed to compare different optimization techniques in cases where Macintosh videolaryngoscopy was difficult. The results showed that both direct epiglottis lifting and conversion to hyperangulated videolaryngoscopy improved glottis visualization, with no significant difference between the two techniques. The combination of both methods yielded the best results.
