Acute Kidney Injury III: Clinical Manifestations01:29

Acute Kidney Injury III: Clinical Manifestations

44
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 V: Interprofessional Care

30
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 IV: Diagnostic Studies and Prevention

40
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...

Cardiac Catheterization I: Pre-Procedure Overview

73
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Acute Kidney Injury I: Introduction01:22

Acute Kidney Injury I: Introduction

38
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...

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...

Summary

Postoperative acute kidney injury (AKI) after extra-cardiac Fontan conversion increases the risk of heart failure re-admission. This finding highlights the importance of monitoring kidney function post-surgery.

Area of Science:

  • Cardiology
  • Nephrology
  • Pediatric Surgery

Background:

  • The Fontan procedure is a palliative surgery for complex congenital heart disease.
  • Extra-cardiac Fontan conversion aims to improve outcomes in Fontan patients.
  • Postoperative complications, including acute kidney injury (AKI), can impact long-term prognosis.

Purpose of the Study:

  • To investigate the association between postoperative AKI and unplanned re-admission due to heart failure.
  • To evaluate this association at a 2-year follow-up period.
  • To analyze outcomes in patients undergoing extra-cardiac Fontan conversion.

Main Methods:

  • Retrospective single-center study.
  • Inclusion of patients who underwent classic to extra-cardiac Fontan conversion (January 2014 - December 2021).
  • AKI diagnosis based on Kidney Disease Improving Global Outcomes (KDIGO) criteria.

Main Results:

  • 47 patients underwent Fontan conversion.
  • AKI occurred in 22 patients (46.8%), with 5 requiring renal replacement therapy.
  • Patients with AKI had a significantly higher rate of unplanned re-admission for heart failure at 2 years (36.4% vs. 12.0%, p=0.026).

Conclusions:

  • Postoperative AKI following extra-cardiac Fontan conversion is linked to increased heart failure re-admission.
  • This association persists even when renal function recovers to baseline.
  • Findings underscore the importance of vigilant renal monitoring in Fontan patients post-conversion.
