    Insights

    Acute kidney injury (AKI) is a critical condition in sick patients. This review summarizes AKI management, focusing on prevention and treatment for perioperative clinicians.

    Area of Science:

    • Nephrology
    • Critical Care Medicine

    Background:

    • Acute kidney injury (AKI) is a frequent complication in critically ill patients.
    • AKI significantly increases patient morbidity and mortality.
    • Management requires addressing diverse etiologies and severity.

    Purpose of the Study:

    • To summarize the clinical management of AKI in critically ill patients.
    • To provide guidance for clinicians in the perioperative setting.
    • To focus on prevention, cause treatment, and supportive care.

    Main Methods:

    • This is a narrative review.
    • Literature search on AKI management strategies.
    • Focus on perioperative clinical practice.

    Main Results:

    • AKI management is multifaceted, involving prevention and treatment.
    • Supportive care, including renal replacement therapy, is often necessary.
    • Tailored approaches are essential due to varying AKI causes and severity.

    Conclusions:

    • Effective AKI management is crucial for critically ill patients.
    • Perioperative clinicians need concise guidance on AKI care.
    • A comprehensive strategy encompassing prevention, treatment, and support improves outcomes.

    Acute Kidney Injury IV: Diagnostic Studies and Prevention

    Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

    Acute Kidney Injury I: Introduction

    Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...

    Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

    Acute Kidney Injury III: Clinical Manifestations

    Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...
