A randomized cross-over study comparing surgical cricothyrotomy techniques by combat medics using a synthetic cadaver...

Area of Science:

• Emergency Medicine
• Surgical Procedures
• Medical Device Technology

Background:

• Cricothyrotomy is a critical airway procedure with a high complication rate.
• Novel devices like Control-Cric™ and QuickTrach II™ aim to improve cricothyrotomy outcomes.
• Comparison of new devices against standard surgical techniques is essential.

Purpose of the Study:

• To compare the efficacy of the Control-Cric™ System and QuickTrach II™ against standard open surgical cricothyrotomy.
• To evaluate time to successful cannulation and first-attempt success rates.
• To assess user preference for the tested cricothyrotomy devices.

Main Methods:

• A randomized crossover study was conducted with US Army combat medics.
• Participants used a synthetic cadaver model to perform cricothyrotomy with three techniques: standard, Control-Cric™, and QuickTrach II™.
• Primary outcome: time to successful cannulation; Secondary outcome: first-attempt success; User preference survey.

Main Results:

• Mean cannulation times were comparable across all three methods (Standard: 51.0s, QuickTrach II™: 39.8s, Control-Cric™: 53.6s).
• Cannulation failure rates (Standard: 6.2%, QuickTrach II™: 13.9%, Control-Cric™: 18.5%) and first-pass success rates (93.4%, 91.1%, 88.7%) showed no significant differences.
• A majority of participants (52.3%) preferred the QuickTrach II™ device.

Conclusions:

• No statistically significant differences were found in time to successful cannulation or first-pass success among the three cricothyrotomy techniques.
• While not statistically significant, the QuickTrach II™ device demonstrated a trend towards faster cannulation and was preferred by users.
• Further research may explore factors influencing user preference and long-term device efficacy.
