AKI Studies

Acute Kidney Injury (AKI) is a well-known complication following surgical procedures. So says the weight of clinical evidence. AKI has negative consequences for patient and healthcare provider, leading to worsened long term prospects and heightened costs of care.

AKI consequences

Randomised Controlled Trials agree that anaesthetists can best avoid AKI if they manage the patient’s fluid balance. This means preventing hypoperfusion while also avoiding fluid overload. Furthermore it requires management of dosing and timing of fluid, inotropes and vasopressors.

Oesophageal Doppler is the leading haemodynamic monitoring technology. It features strongly in the main clinical studies. The system’s sophisticated algorithm delivers real-time, accurate flow and pressure data direct from the aorta. As a result, it provides the anaesthetist with a degree of control that informs clinical decisions. Moreover it enables them to keep the patient in their haemodynamic “sweet spot”. In so doing it avoids stress to the vital organs and helps to minimise AKI and other complications.

Unequalled body of supportive clinical evidence shows AKI reduction

The independent body of clinical evidence confirms the role of haemodynamic monitoring in achieving significant reductions in peri-operative AKI, even in patients considered to be low risk.
