Prolonged Field Care Podcast 174: AAJT

In this episode, Dennis interviews John and Paul about the Abdominal Aortic and Junctional Tourniquet (AAJT). They discuss the background and reasons for inventing the AAJT, including the need to control bleeding in the pelvis. They also talk about the first application of the AAJT and the positive results seen in combat situations. The conversation then moves on to study data and research on the device, including some negative studies that have been conducted. They also discuss the pressure levels used with the AAJT and the potential for extending the application time. Finally, they address the negative consequences of high pressure and the comfort level of wearing the device. The conversation explores the application and function of the Abdominal Aortic Junctional Tourniquet (AAJT) and its potential use in pre-hospital care. It discusses the challenges of prolonged application and the risks associated with it. The conversation also delves into alternative techniques and future developments in the field. The importance of reperfusion and monitoring is highlighted, along with the impact of the AAJT on breathing and inspiratory pressure. The discussion touches on the considerations for reducing pressure during reperfusion and the duration of application. The risk-benefit analysis of heroic interventions is examined, emphasizing the need for rapid hemorrhage control. The limitations and risks of Roboa are discussed, and a cadaveric study on the AHAT is presented. The conversation concludes with the role of the AHAT in preparing for future wars and its potential use in traumatic cardiac arrest.

Takeaways
The AAJT was invented to control bleeding in the pelvis and junctional areas.
The device has been successfully used in combat situations and has saved lives.
There have been several studies conducted on the AAJT, with mixed results.
The device applies pressure to occlude blood flow, but the pressure levels are safe and well-tolerated. The Abdominal Aortic Junctional Tourniquet (AAJT) is a fielded device that can be used for rapid hemorrhage control in non-compressible torso hemorrhage.
Prolonged application of the AAJT should be avoided, and it is important to consider the risks and benefits of its use.
Alternative techniques and future developments, such as foams, are being explored for the treatment of non-compressible torso hemorrhage.
Reperfusion and monitoring are crucial considerations when using the AAJT, and the pressure can be reduced during transfusion to mitigate ischemic change.
The AAJT has shown promising results in traumatic cardiac arrest and can be a valuable tool in pre-hospital care.
