Official title
Abdominal Aortic Junction Tourniquet (AAJT-S) for Non-compressible Torso Haemorrhage A Prospective Multicentre-study
Overview
This study seeks to evaluate the feasibility of a Abdominal Aortic Balloon Occlusion of the Aorta (AAJT-S) in exanguinating trauma patients with non-compressible truncal haemorrhage in the emergency room and the pre-hospital setting.
Detailed description
Much like REBOA, AAJT-S can potentially stop blood flow distal to the device and therefore improve proximal aortic perfusion, minimize haemorrhage and stabilize patients until definite surgical repair/bleeding control is feasible. In contrast to REBOA, there is no need of femoral access and therefore, appropriate training is easily achieved.
This study seeks to gather further information on the benefits and potential harms of this intervention on a multicentre level.
Primary outcome measures
- effective placement of the device [Time frame: 1 hour]
Secondary outcome measures (3)
- Outcome Measure [Time frame: 30 days]
- Complications [Time frame: 90 days]
- hemodynamic improvement after application [Time frame: 1 hour]
Eligibility criteria
Inclusion criteria
- Written consent of the participant after being informed
- Aged, or believed to be aged, 18 years or above
- Confirmed or suspected life-threatening lower body trauma (i.e. signs of inadequate perfusion of tissues, tachycardia, hypotension, suspected blood loss)
- Thought to benefit from trauma resuscitation with AAJT-S or REBOA zone III
- Traumatic cardiac arrest
