Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
