This systematic review aims to assist clinical decision-making in selecting appropriate preoperative prediction methods for difficult tracheal intubation by identifying and synthesizing literature on these methods in adult patients undergoing all types of surgery. 

Evaluation of preoperative difficult airway prediction methods for adult patients without obvious airway abnormalities: a systematic review and meta-analysis

Controllo delle vie aeree in anestesia

Control de las vías respiratorias en anestesiología

The practice of pediatric anesthesia, especially when performed for pediatric airway disorders, has evolved remarkably over the past century. This chapter will cover the interesting story of the evolution of anesthesia beginning with ether and later development of mask, endotracheal tube, LMA and TIVA, and current state of the art and highlight current areas of controversy regarding pediatric airway management.

Evolution of Anesthesia for Pediatric Airway Surgery: From Ether to TIVA and Current Controversies

<title>Abstract</title> <bold>Background: </bold>The presence of giant epiglottic cysts can lead to throat discomfort, foreign body sensation within the throat and respiratory distress. However, asymptomatic sufferers who remain undiagnosed may additionally face demanding situations in airway control during anesthesia emergencies. In intense instances, a tracheotomy may be required. <bold>Case presentation:</bold> A 61-year-old male, recognized with heel spur, underwent optionally available arthroscopic osteotomy. However, ventilation was difficult during anesthesia and impossible post-laryngeal mask insertion. Video laryngoscopy revealed a giant epiglottic cyst. Tracheal intubation under video laryngoscopy was eventually successful. <bold>Conclusion: </bold>In asymptomatic giant epiglottic cysts, preoperative anaesthetic assessment must be comprehensive, especially regarding the risk of a difficult airway. If the epiglottic cyst is discovered during anaesthesia, a difficult airway should be managed appropriately. Prompt use of video laryngoscopy in difficult airways increases successful intubation probability and appropriate ventilation tools may aid ventilation in cases of failed intubation. However, calling for help in all cases remains paramount. 

Asymptomatic giant epiglottic cyst causing an unexpectedly difficult airway: A case report

Routine preoperative methods to assess airway such as the interincisor distance (IID), Mallampati classification, and upper lip bite test (ULBT) have a certain risk of upper respiratory tract exposure and virus spread. Condyle-tragus maximal distance(C-TMD) can be used to assess the airway, and does not require the patient to expose the upper respiratory tract, but its value in predicting difficult laryngoscopy compared to other indicators (Mallampati classification, IID, and ULBT) remains unknown. The purpose of this study was to observe the value of C-TMD to predict difficult laryngoscopy and the influence on intubation time and intubation attempts, and provide a new idea for preoperative airway assessment during epidemic. Adult patients undergoing general anesthesia and tracheal intubation were enrolled. IID, Mallampati classification, ULBT, and C-TMD of each patient were evaluated before the initiation of anesthesia. The primary outcome was intubation time. The secondary outcomes were difficult laryngoscopy defined as the Cormack-Lehane Level > grade 2 and the number of intubation attempts. Three hundred four patients were successfully enrolled and completed the study, 39 patients were identified as difficult laryngoscopy. The intubation time was shorter with the C-TMD>1 finger group 46.8 ± 7.3 s, compared with the C-TMD 1 finger group 98.9% than in the C-TMD<1 finger group 87.1% (P<0.01). The correlation between the C-TMD and Cormack-Lehane Level was 0.317 (Spearman correlation coefficient, P<0.001), and the area under the ROC curve was 0.699 (P<0.01). The C-TMD < 1 finger width was the most consistent with difficult laryngoscopy (κ = 0.485;95%CI:0.286–0.612) and its OR value was 10.09 (95%CI: 4.19–24.28), sensitivity was 0.469 (95%CI: 0.325–0.617), specificity was 0.929 (95%CI: 0.877–0.964), positive predictive value was 0.676 (95%CI: 0.484–0.745), negative predictive value was 0.847 (95%CI: 0.825–0.865). Compared with the IID, Mallampati classification and ULBT, C-TMD has higher value in predicting difficult laryngoscopy and does not require the exposure of upper respiratory tract. The study was registered on October 21, 2019 in the Chinese Clinical Trial Registry (
 ChiCTR1900026775
 ).
