To evaluate cricothyroidotomy in the field and the influence of physicians' medical specialty or previous experience on the success rate of this procedure, a retrospective study was conducted. Between October 1991 and April 1995, 29 cricothyroidotomies were performed in the prehospital setting in Israel. Twenty-six (89.6%) cricothyroidotomies were successfully performed. ⋯ All physicians had successfully completed the Advanced Trauma Life Support (ATLS) course, but only three had previously performed cricothyroidotomy. Acute complications included failure to establish an airway in 3 cases, minor bleeding in 2 cases, and an air leak around the cannula in 1 patient. These results show that following brief training (eg, the ATLS course) physicians are capable of performing emergency cricothyroidotomy in the field with a high success rate and minimal complications, regardless of medical specialty.

Early identification of patients presenting with myocardial infarction (MI) is necessary for rapid initiation of treatment. Currently, MI has been diagnosed using the combination of the history, electrocardiogram (ECG), and biochemical markers of myocardial necrosis. Unfortunately, all lack sufficient sensitivity and specificity to confidently identify most patients with MI in a timely enough fashion to influence early intervention. ⋯ When patients with diagnostic ECGs were excluded, the sensitivity of the combination at 0 hours was 80% with a specificity of 84%, while the use of the 0- and 4-hour markers had a sensitivity and specificity of 100% and 100%, respectively. We conclude that the combination of CK-MB mass and myoglobin can rapidly diagnose or exclude MI in as short as 4 hours after ED presentation, and accuracy is not different in patients without diagnostic ECGs. Application of this strategy could potentially lead to more rapid intervention in patients with MI, while also allowing early identification of lower risk patients.
