Insights

This bibliometric analysis reveals trends in contrast-induced acute kidney injury (CI-AKI) research. Clinical trials are a current hotspot, with future work focusing on injury mechanisms to reduce CI-AKI incidence.

Area of Science:

  • Nephrology
  • Radiology
  • Bibliometrics

Background:

  • Contrast-induced acute kidney injury (CI-AKI) is a significant cause of hospital-acquired kidney injury.
  • No prior bibliometric analyses have comprehensively reviewed CI-AKI research.

Purpose of the Study:

  • To conduct a bibliometric analysis of CI-AKI literature.
  • To identify research trends, hotspots, and future directions in the field.

Main Methods:

  • Literature search of the Web of Science Core Collection.
  • Data analysis using CiteSpace and VOSviewer software.
  • Analysis of 4775 papers published on CI-AKI.

Main Results:

  • The United States and Guangdong Acad Med Sci are leading contributors.
  • J AM COLL CARDIOL published the most articles.
  • Clinical trials, risk assessment, prevention strategies, risk factors, and vascular lesions are key research areas.

Conclusions:

  • Clinical trials represent a current research focus in CI-AKI.
  • Future research should prioritize understanding CI-AKI injury mechanisms.
  • Investigating mechanisms is crucial for reducing clinical CI-AKI incidence.

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...

Acute Kidney Injury II: Pathophysiology

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

Acute Kidney Injury V: Interprofessional Care

Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...

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...

Acute Kidney Injury VI: Nursing Management

Acute Kidney Injury (AKI) results in an inability to maintain fluid, electrolyte, and acid-base balance. Effective nursing management is critical in improving patient outcomes and includes comprehensive patient assessment and targeted interventions.Comprehensive Patient AssessmentA detailed history collection is essential, focusing on any recent infections, nephrotoxic medication use, or chronic conditions such as hypertension and diabetes that may contribute to AKI.
