ischuria renalis, was by William Heberden in 1802.

At the beginning of the twentieth century, Acute Bright’s disease, was well described in William Osler’s Textbook for Medicine (1909), as a consequence of toxic agents, pregnancy, burns, trauma, or operations on thekidneys.

During the First WorldWar the syndrome was named ‘‘war nephritis’’, and was reported in several publications.

The syndrome was forgotten until the Second World War, when Bywaters and Beall published their classical paper on crush syndrome.

It is Homer W. Smith who is credited for the introduction of the term ‘‘acute renal failure’’, in a chapter on ‘‘Acute renal failure related to traumatic injuries’’ in his textbook The kidney-structure and function in health and disease (1951).

AKI is defined by an abrupt decrease in kidney function that includes, but is not limited to, ARF.

Because the manifestations and clinical consequences of AKI can be quite similar (even indistinguishable) regardless of whether the etiology is predominantly within the kidney or predominantly from outside stresses on the kidney, the syndrome of AKI encompasses both direct injury to the kidney as well as acute impairment of function.

Define and stage AKI after administration of intravascular contrast media as per Recommendations.

In individuals who develop changes in kidney function after administration of intravascular contrast media, evaluate for CI-AKI as well as for other possible causes of AKI.

Many studies have now shown that patients who develop CI-AKI have a greater risk for death or prolonged hospitalization, as well as for other adverse outcomes, including early or late cardiovascular events.

when patients with CI-AKI require dialysis, the mortality is higher compared to those not requiring dialysis.

Additional radiological measures to reduce CI-AKI

Some CT strategies in patients at risk of CI-AKI Perform CT, when possible, without contrast media. Dosing per kilogram body weight to reduce the

amount of contrast media is needed in thin patients. Adapt injection duration to scan duration when

performing CT-angiography, so that the injection is not still running when the scan is finished.

Use a saline chaser to decrease the amount of contrast media, by using the contrast medium that otherwise would remain in the dead space of the arm veins; this may save 10–20 ml of contrast media.

…Some CT strategies in patients at risk of CI-AKI

Further reduction of contrast media may be instituted in patients with known decreased cardiac output (not unusual in patients with renal impairment) undergoing CT-angiographic studies.

Some angiographic strategies in patients at risk of CI-AKI

Avoid test injections; the same amount may be enough for a diagnostic digital-subtraction angiography run.

Scrutinize each series before performing the next; avoid unnecessary projections.

Decrease kilovoltage in a thin patient; a lower iodine concentration may be used.

Page 50: In the name of GOD 1. 2 ischuria renalis, was by William Heberden in 1802. At the beginning of the twentieth century, Acute Bright’s disease, was

50

Avoid ventriculography: echocardiography (and ‘‘echo contrast’’) is always a reasonable alternative.

Use plasma isotonic contrast-media concentrations for renal artery injections.

CO2 may be used as contrast medium in venous examinations and below the diaphragm for arterial examinations or alternatively use iodinated contrast media with the same contrast effect, i.e., about 40mg iodine per milliliter.

Page 51: In the name of GOD 1. 2 ischuria renalis, was by William Heberden in 1802. At the beginning of the twentieth century, Acute Bright’s disease, was

51

We recommend using either iso-osmolar or low osmolar iodinated contrast media, rather than high-osmolar iodinated contrast media in patients at increased risk of CI-AKI.

Use selective or superselective catheterizations when appropriate, e.g., ‘‘single leg run-off’’.

We recommend i.v. volume expansion with either isotonic sodium chloride or sodium bicarbonate solutions, rather than no i.v. volume expansion, in patients at increased risk for CI-AKI.

Page 54: In the name of GOD 1. 2 ischuria renalis, was by William Heberden in 1802. At the beginning of the twentieth century, Acute Bright’s disease, was

We recommend not using oral fluids alone in patients at increased risk of CI-AKI.

Page 55: In the name of GOD 1. 2 ischuria renalis, was by William Heberden in 1802. At the beginning of the twentieth century, Acute Bright’s disease, was

Initiate RRT emergently when life-threatening changes in fluid, electrolyte, and acid-base balance exist.

Page 62: In the name of GOD 1. 2 ischuria renalis, was by William Heberden in 1802. At the beginning of the twentieth century, Acute Bright’s disease, was

62

Consider the broader clinical context, the presence of conditions that can be modified with RRT, and trends of laboratory tests—rather than single BUN and creatinine thresholds alone—when making the decision to start RRT.

Potential applications for RRT

Renal support This approach is based on the

utilization of RRT techniques as an adjunct to enhance kidney function, modify fluid balance, and control solute levels.

Page 64: In the name of GOD 1. 2 ischuria renalis, was by William Heberden in 1802. At the beginning of the twentieth century, Acute Bright’s disease, was

64

Volume control Recent studies have shown

potential benefits from extracorporeal fluid removal in CHF.

Intraoperative fluid removal using modified ultrafiltration has been shown to improve outcomes in pediatric cardiac surgery patients.

65

Potential applications for RRT Nutrition Restricting volume

administration in the setting of oliguric AKI may result in limited nutritional support and RRT allows better nutritional supplementation.

Drug delivery RRT support can enhances the

ability to administer drugs without concerns about concurrent fluid accumulation.

Page 66: In the name of GOD 1. 2 ischuria renalis, was by William Heberden in 1802. At the beginning of the twentieth century, Acute Bright’s disease, was

66

Regulation of acid-base and electrolyte status

Permissive hypercapnic acidosis in patients with lung injury can be corrected with RRT, without inducing fluid overload and hypernatremia.

Solute modulation Changes in solute burden should be anticipated :tumor lysis syndrome. Although current evidence is unclear,studies are ongoing to assess the efficacy of RRT for cytokine manipulation in sepsis.

Discontinue RRT when it is no longer required,

either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs, or because RRT is no longer consistent with the goals of care.

Page 69: In the name of GOD 1. 2 ischuria renalis, was by William Heberden in 1802. At the beginning of the twentieth century, Acute Bright’s disease, was

69

We suggest not using diuretics to enhance kidney function recovery, or to reduce the duration or frequency of RRT.

In a patient with AKI requiring RRT, base the decision to use anticoagulation for RRT on assessment of the patient’s potential risks and benefits from anticoagulation .

Page 72: In the name of GOD 1. 2 ischuria renalis, was by William Heberden in 1802. At the beginning of the twentieth century, Acute Bright’s disease, was

72

For patients without an increased bleeding risk or impaired coagulation and not already receiving effective systemic anticoagulation, we suggest the following:

For anticoagulation in intermittent RRT, we recommend using either unfractionated or low-molecular-weight heparin, rather than other anticoagulants.

Page 73: In the name of GOD 1. 2 ischuria renalis, was by William Heberden in 1802. At the beginning of the twentieth century, Acute Bright’s disease, was

73

For patients with increased bleeding risk who are not receiving anticoagulation, we suggest the following for anticoagulation during RRT:

We suggest using regional citrate anticoagulation, rather than no anticoagulation, during CRRT in a patient without contraindications for citrate.

Page 74: In the name of GOD 1. 2 ischuria renalis, was by William Heberden in 1802. At the beginning of the twentieth century, Acute Bright’s disease, was

74

In a patient with HIT, all heparin must be stopped and we recommend using direct thrombin inhibitors (such as argatroban) or Factor Xa inhibitors (such as danaparoid or fondaparinux) rather than other or no anticoagulation during RRT.

In a patient with HIT who does not have severe liver failure, we suggest using argatroban rather than other thrombin or Factor Xa inhibitors during RRT.

When choosing a vein for insertion of a dialysis catheter in patients with AKI, consider these preferences (Not Graded):

First choice: right jugular vein; Second choice: femoral vein; Third choice: left jugular vein; Last choice: subclavian vein with

preference for the dominant side.

Page 81: In the name of GOD 1. 2 ischuria renalis, was by William Heberden in 1802. At the beginning of the twentieth century, Acute Bright’s disease, was

We recommend obtaining a chest radiograph

promptly after placement and before first use of an internal jugular or subclavian dialysis catheter.

100Prevention of aminoglycoside- and amphotericin-related AKI

Page 101: In the name of GOD 1. 2 ischuria renalis, was by William Heberden in 1802. At the beginning of the twentieth century, Acute Bright’s disease, was

101

We suggest not using aminoglycosides for the treatment of infections unless no suitable, less nephrotoxic, therapeutic alternatives are available.

Page 102: In the name of GOD 1. 2 ischuria renalis, was by William Heberden in 1802. At the beginning of the twentieth century, Acute Bright’s disease, was

102

We suggest that, in patients with normal kidney function in steady state, aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens.

Page 103: In the name of GOD 1. 2 ischuria renalis, was by William Heberden in 1802. At the beginning of the twentieth century, Acute Bright’s disease, was

103

We recommend monitoring aminoglycoside drug levels when treatment with multiple daily dosing is used for more than 24 hours.

Page 104: In the name of GOD 1. 2 ischuria renalis, was by William Heberden in 1802. At the beginning of the twentieth century, Acute Bright’s disease, was

We suggest monitoring aminoglycoside drug levels when treatment with single-daily dosing is used for more than 48 hours.

Page 105: In the name of GOD 1. 2 ischuria renalis, was by William Heberden in 1802. At the beginning of the twentieth century, Acute Bright’s disease, was

105

We suggest using topical or local applications of aminoglycosides (e.g., respiratory aerosols, instilled antibiotic beads), rather than i.v. application, when feasible and suitable.

Page 106: In the name of GOD 1. 2 ischuria renalis, was by William Heberden in 1802. At the beginning of the twentieth century, Acute Bright’s disease, was

106

We suggest using lipid formulations of amphotericin B rather than conventional formulations of amphotericin B.
