Renal Perfusion and the Development of AKI Following Traumatic Injury

Renal Perfusion and the Development of AKI Following Traumatic Injury - A Longitudinal Observational Cohort Study

Acute kidney injury (AKI) is a complication of traumatic haemorrhagic shock (THS) and together these conditions increase mortality risk. Although septic shock patients who develop severe AKI are known to develop hypoperfusion of the renal cortex, little is known regarding intra-renal perfusion changes in THS. The aim of the current study is to investigate the effects of THS on renal microcirculatory perfusion.

Inclusion Criteria:

• Age > 18 years
• Within 24 hours of ICU admission following traumatic injury
• Received any blood products during initial resuscitation
• Lactate > 2 mmol/l at any stage prior to study enrolment

Exclusion Criteria:

• Known intolerance to Sonovue or any other ultrasound contrast agent
• Patients with un-survivable injuries / not expected to survive 24 hours in whom the intent of treatment is palliative
• Known CKD 4 or end stage renal failure
• Pregnancy
