Abdominal Aortic Junction Tourniquet (AAJT-S) for Non-compressible Torso Haemorrhage

Abdominal Aortic Junction Tourniquet (AAJT-S) for Non-compressible Torso Haemorrhage: a Prospective Observational Pilot Study

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.

The study is designed as a prospective observational study to accomapany the impementation of this device in clinical routine. However, the device has already been used in the emergency room and AAJT-S application is no study specific intervention.

Inclusion Criteria:

• 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)
• is thought to benefit from trauma resuscitation with AAJT-S or REBOA zone III

Exclusion Criteria:

• suspected additional bleeding source proximal to the umbilicus, or
• known or suspected pregnancy at presentation, or
• known abdominal aortic aneurysm
