The applicability of telemedicine is vast and increasingly relevant. There is a lack of research on utilizing telemedicine for remote evaluation of the airway. The primary aim of this pilot study was to validate a telemedical airway exam as a viable alternative to an in-person evaluation. Three anesthesiologists evaluated 48 volunteers by telemedicine and live examination. The telemedical exam consisted of transmitting still images of four established, predictive parameters of difficult airways: Mallampati score;neck extension;ability to prognath;and thyromental distance. Each subject’s telemedical and face-to-face scores were compared to determine their degree of correlation. Still images were taken using standardized positioning with four pictures of mouth opening, neck extension, prognath, and thyromental distance. Data were analyzed using Wilcoxon signed-rank tests and free-marginal multirater kappa analysis. Average respective scores for live versus telemedicine examination were as follows: Mallampati scores were 1.73 versus 2.54;neck extension scores were 3.77 versus 3.60;thyromental distance (measured in finger breadths) was 2.95 versus 2.92;and prognath scores were 0.97 versus 0.94. There was no difference in grading of thyromental distance or prognathy ability between live and telemedical exams, and interrater reliability was very good for both parameters. This study supports telemedicine as a reliable tool for preoperative anesthesia airway exams to identify airway difficulties. This may be especially useful as an alternative in patients with COVID-19 undergoing urgent surgery.展开更多
