Patients undergoing elective or in-house urgent cardiac surgery will be approached for the KIDNEY study if they fulfil the inclusion criteria. Upon consent pre-operative blood tests will be as per the usual practice. Moreover, 2ml of the serum will be stored for NGAL analysis.
Following the consenting process, patients will be randomised (envelop- based) into either having the RenalGuard® System (Study group) or current medical management (Control group).
Patients in the study group will have the RenalGuard® System started in anaesthetic room once the peripheral line and arterial lines are sited. The RenalGuard® System will continue to run throughout the cardiac procedure in the operating room and up to 6 hours post-op after the patient has been transferred to the unit. Patients will be managed at a zero balance i.e. volume of the urine output will be matched to the volume of Hartmann's fluid infusion. Forced diuresis is then initiated.
Patients in the control group will be managed as per current medical practice which will include no forced diuresis in operating room and the use of inotropes for maintenance of mean arterial pressure and intravenous furosemide for diuresis.
An additional blood test (NGAL) at six hours post-op will be taken and would require 2mls of blood. The NGAL specimens will be dealt with by the biochemistry lab (centrifuged & stored) so that the specimens can be analysed in batches.
Patients kidney function (U&Es) will be tested at the time of post-operatively as per usual practice (Day1, pre-discharge and as clinically indicated) and at the post-operative surgical out-patient visit.
Pre-operative, intra-operative and post-operative data will be collected for each patient group.
