Quick cuts: A comparative study of two tools for ring tourniquet removal

Area of Science:

• Emergency Medicine
• Traumatology
• Medical Device Evaluation

Background:

• Ring tourniquets, caused by entrapped rings, can lead to severe finger swelling and complications.
• Prompt ring removal is critical in emergency situations to prevent nerve damage and other adverse outcomes.
• Existing ring removal devices lack sufficient comparative efficacy data.

Purpose of the Study:

• To compare the efficacy, user satisfaction, and complication rates of two ring removal devices.
• To evaluate the performance of a motorized diamond disc ring cutter (MDDRC) versus ring cutters attached to trauma shears (TS).

Main Methods:

• A randomized study involving emergency medicine providers removing rings from 30 subjects.
• Ring removal time was measured for both MDDRC and TS devices.
• User and participant satisfaction, along with complications, were assessed using visual analog scales.

Main Results:

• Trauma shears (TS) demonstrated significantly faster ring removal times (7.7s) compared to MDDRC (67.0s).
• Both user and participant satisfaction scores were significantly higher with the TS device.
• Participant discomfort was significantly lower when using the TS device.

Conclusions:

• The trauma shears (TS) device is a more effective and satisfactory tool for emergency ring tourniquet removal than the MDDRC.
• This study provides the first comparative data on the efficacy and satisfaction of these two common ring removal tools.
• Faster removal and higher satisfaction suggest TS as a preferred method in emergency settings.
