Lee D, et al. - Given accurate localisation of the cricoid cartilage has relevance for the safe conduct of rapid sequence induction, researchers investigated the accuracy of conventional landmark technique for cricoid localisation using ultrasound scanning in 100 patients in this multicentre, prospective cohort study. Findings pointed to a high degree of variability with regard to identification of cricoid position using a landmark technique. Furthermore, identification of cricoid position via this technique had little correlation with age, sex or body mass index. These findings have significant implications for the safe application of cricoid pressure in the context of rapid sequence induction.
