Basaran B, et al. - Given accurate identification of the cricothyroid membrane (CTM) has paramount importance in the event of a ‘cannot intubate, cannot oxygenate’ scenario, researchers investigated whether anesthesiologists were able to correctly identify the CTM in obese and non-obese children. They asked anesthesiologists to mark the entry point of the cricothyroidotomy device with an ultraviolet invisible pen on obese and non-obese (BMI < 95th percentile for age and sex) children aged 7–12 years. The definition of a correct estimation was a mark made between the upper and lower borders of the CTM and within the 3-mm midline. They found that CTM was poorly identified, percutaneously, in children aged 7–12 years. They also noted that percutaneous identification of the CTM was not significantly different for obese and non-obese children. In addition, the landmarks for cricothyroidotomy may be identified via pre-procedural ultrasonography.
