Summary: In a randomized trial of 140 adult patients undergoing general anesthesia, paratracheal pressure was found to be noninferior to cricoid pressure in terms of its effect on glottic view during direct laryngoscopy. Additionally, it was easier for mask ventilation and led to a decrease in peak inspiratory pressure during mechanical ventilation compared to cricoid pressure.

Summary: The study found that the dimensions of the cricoid cartilage change with age in adult population, with males having larger cricoid diameters and angle than females. The shape of the cricoid outlet varies greatly among individuals.

Summary: This report presents a rare case of delayed subglottic stenosis in a 17-year-old female who suffered severe neck trauma in a car accident. She developed dyspnea 30 days later and eventually died 58 days after the accident due to hypoxic-ischemic encephalopathy and severe pulmonary infection. The postmortem findings revealed tracheal stenosis caused by a cricoid cartilage fracture, fibrous tissue proliferation, and inflammatory cell infiltration.

Summary: In this meta-analysis, the application of cricoid pressure did not significantly affect the successful first-attempt intubation rate or laryngoscopic view, but it may slightly prolong intubation time and increase the risk of postoperative hoarseness.

Summary: Difficulties in airway management were observed in two dogs with narrow cricoid cartilage, leading to the use of smaller endotracheal tubes or supraglottic airway devices. The narrowness of the cricoid cartilage may be associated with brachycephalic airway syndrome, making posterior glottic intubation easier in these cases. This is the first clinical case report highlighting the challenges of airway management in dogs with narrow cricoid cartilage.

Summary: This study compared the first-attempt success rate and complications of sedated tracheal intubation versus tracheal intubation under general anesthesia in children with difficult airways. The results showed that sedation and general anesthesia had a similar rate of first-attempt success. However, 27.6% of the sedation cases needed to be converted to general anesthesia to complete tracheal intubation. The overall rate of complications was similar between the groups, and the rate of severe complications was low.

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: A 76-year-old man with dyspnea and initial prostate-specific antigen of 216 ng/mL was diagnosed with prostate cancer. Despite initial therapy, he later developed castration-resistant state with additional tumors detected. The use of PET/CT scans revealed metastasis to T5 vertebra and duodenum.

Summary: This study aimed to define the length of the subglottis and trachea in children to predict a safe intubation depth. The best predictor of subglottic and tracheal length was found to be patient height. Current strategies for determining appropriate depth of intubation were found to pose a high risk of subglottic endotracheal tube cuff placement.

Summary: This study confirms the glottis as the narrowest level of the larynx in young children. Croup-related narrowing is more severe closer to the glottis.

Summary: This study measured anthropometric parameters of bilateral internal jugular veins in children and determined the best puncture site. The right internal jugular vein at the cricoid cartilage level was found to be the most suitable site for puncture. There was a weak correlation between the anthropometric parameters and children's biological characteristics.

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