Comparison of emergency airway management techniques in the performance of emergent Cricothyrotomy

INTRODUCTION: Emergent cricothyrotomy (EC) is a rare and lifesaving procedure to secure a difficult airway when other methods have failed. Many techniques have been discussed in the literature. This study aimed to identify major techniques used to perform EC in a regional trauma center and evaluate outcomes associated with the techniques. METHODS: Patients who underwent EC at Arrowhead Regional Medical Center between 1-1-2009 and 1-1-2019 were reviewed for eligibility for this study. Patients’ data were extracted from the trauma database. Chi-square tests were conducted to assess the difference on variables between the techniques. RESULTS: A total of 51 (0.17%) of these patients required EC and were included in the database. The two most prevalent techniques were the scalpel-bougie-tube (SBT) and the surgical cricothyrotomy technique (SCT). More than half (n = 27, 52.9%) of the cohort received the SBT. There was no statistically significant difference between the two techniques with regards to demographic variables, including age (p = 0.7528), injury severity score (ISS, p = 0.896), gender (p = 0.3709), and race (p = 0.8935). However, the SCT group had a statistically higher Glasgow Coma Scale (GCS) than the SBT group (p = 0.0036). There was no statistically significant difference in mortality or complications between these two groups (p = 0.2172 for mortality). DISCUSSION: Two techniques of EC were identified as preferred techniques. Both procedures were successful in securing an emergency airway, noting a difference in the time to completion of the two techniques. Given the rarity of the procedure, practitioners may choose the method based on their training and the availability of appropriate instruments.
