Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intravenous infusion of 20% albumin. The infusion will begin within 6 hours of surgery and will be administered for 15 hours at 20mL/hour. The infusion will be given in addition to standard care as per the clinician in charge.

Adherence to the study protocol will be monitored via clinical notes (e.g. ICU observation charts).
Intervention code [1] 315572 0
Treatment: Drugs
Intervention code [2] 315645 0
Prevention
Comparator / control treatment
Standard care as per the clinician incharge. This includes any background treatments considered routine care and may include vasopressors, inotropes, ventilation and initiation of dialysis. Patients in the standard care arm will be permitted to receive 4% albumin fluid but will not be permitted to receive 20% albumin within the first 24hrs following enrolment.

Efficacy
Statistical methods / analysis
Sample size was determined according to the following characteristics:
Anticipated incidence (comparator): 30%
Anticipated incidence (intervention): 20%
Enrolment ratio: 1:1
Alpha: 0.05
Power: 0.8

Data will be analysed using an intention-to-treat methodology.

Normal distribution of continuous data will be assessed. Continuous variables will be expressed as mean ± SD or median (IQR). Differences between the two cohorts of patients will be tested. Categorical variables will be described as frequency (%).

The relative risk (RR) and the median differences (Albumin group vs comparator group), including 95% confidence intervals, will be used to describe the differences of perioperative characteristics, the occurrence of AKI, hospital mortality, and initiation of dialysis.
