Two thirds of patients had a significant level of AKI before a diagnosis was made and there was inadequate senior review of these patients... More severe AKI is associated with higher mortality... Temporary cessation of ACEi and ARBs is appropriate in patients with dehydration, hypotension (systolic blood pressure < 110 mmHg) and / or deteriorating renal function... However, hypotension (SBP < 110 mmHg), a postural fall in blood pressure with increase in heart rate, reduction in peripheral perfusion / skin turgor and dry mucous membranes are indicative signs... Large volumes of 0.9% sodium chloride can provoke a hyperchloraemic metabolic acidosis... Failure of the patient to maintain an effective blood pressure following this regime should raise the possibility of underlying sepsis or significant ongoing losses... Absolute hypotension (defined as a SBP < 90 mmHg) has been shown to be associated with the development of AKI following sepsis and major surgery... In patients with AKI and hypotension, blood pressure should be targeted to a MAP of > 65 mmHg... It should be stressed that there is no evidence for a role for “renal dose” dopamine in the management of AKI... In addition, dobutamine has significant vasodilatory effects which can aggravate hypotension and worsen renal perfusion in patients with sepsis and AKI... Antihypertensive medications (including diuretics) should be withheld in patients with both absolute (SBP < 90 mmHg) and relative (SBP < 120 mmHg) hypotension... Patients treated with beta blockers need careful consideration of the risk / benefit of temporary cessation... The indication for dialysis is based on the complications of AKI rather than an absolute value for serum urea, creatinine or GFR... There is no clear benefit for undertaking dialysis solely on the basis of a low GFR.

Mentions: Perioperative AKI is common. Recognition of patients who are at risk will allow measures to be undertaken to reduce exposure to renal insults and maximize renal recovery should AKI occur14. An similar risk assessment tool for use in Surgical patients is shown in Figure 6.
