Indicators Of Fontan Circulatory Failure In Pediatric Patients: A Scoping Review Of Early Clinical And Hemodynamic Factors, Marina Mcmahon Apr 2026

Indicators Of Fontan Circulatory Failure In Pediatric Patients: A Scoping Review Of Early Clinical And Hemodynamic Factors, Marina Mcmahon

Student Works

Structured Summary

a. Background/Introduction:

For patients with single ventricle congenital heart disease, the Fontan procedure is the definitive palliative procedure. Although advancements have been made in the surgical technique and management, the Fontan circulation is inefficient and prone to progressive dysfunction. Elevated central venous pressure, non-pulsatile pulmonary blood flow, and reduced cardiac output can lead to many complications, and eventual failure. These conditions can lead to protein losing enteropathy, plastic bronchitis, and hepatic fibrosis which often indicate advanced decline. Though a known problem, there is a lack of standardized criteria to guide optimal intervention timing of Fontan revision prior to …

The Impact Of Normothermic Regional Perfusion Compared With Cold Storage On Warm Ischemia Time In Donation After Circulatory Death Organ Transplantation: A Scoping Review, Chris Turner

Student Works

ABSTRACT

2.Structured summary:

Background: Donation after circulatory death (DCD) has expanded the donor pool but introduces an inevitable period of warm ischemia that threatens graft viability. Preservation techniques such as normothermic regional perfusion (NRP) and static cold storage (SCS) aim to minimize this injury and improve transplant outcomes.

Objective: This scoping review identifies and synthesizes published evidence comparing NRP with SCS in DCD organ transplantation, focusing on their respective effects on warm ischemia time, graft function, and early post‑transplant outcomes.

Methods: Following the PRISMA‑ScR framework [23], searches were conducted in MEDLINE, PubMed, Embase, and Scopus for English‑language studies involving DCD …


Pharmacologic Interventions To Reduce Cardiopulmonary Bypass Induced Inflammation In Cardiac Surgery: A Scoping Review, Wyatt Anderson Apr 2026

Pharmacologic Interventions To Reduce Cardiopulmonary Bypass Induced Inflammation In Cardiac Surgery: A Scoping Review, Wyatt Anderson

Student Works

ABSTRACT

  1. Structured summary

Background

Cardiopulmonary bypass (CPB) is essential in cardiac surgery but can trigger a systemic inflammatory response that contributes to postoperative complications. The scoping review conducted has a purpose to map the existing literature on pharmacologic interventions to mitigate CPB related inflammation. While several interventions demonstrated potential anti-inflammatory effects, findings were inconsistent, and no standardized pharmacologic approach is currently agreed upon.

Methods

This scoping review followed PRISMA-ScR guidelines.Both PubMed, and CINAHL were screened for studies published between 2000 and 2024 that evaluated pharmacologic interventions aimed at reducing CPB related inflammation. After screening and duplicate removal, 10 studies met …


Pharmacological Treatment Options For Vasoplegia Syndrome During And After Cardiopulmonary Bypass: A Scoping Review, Bradley Darby Apr 2026

Pharmacological Treatment Options For Vasoplegia Syndrome During And After Cardiopulmonary Bypass: A Scoping Review, Bradley Darby

Student Works

ABSTRACT

2: Structured summary

Background

Vasoplegia Syndrome (VS) is a form of distributive shock that is characterized by profound hypotension, low systemic vascular resistance, and high to normal cardiac output during/after cardiopulmonary bypass. VS is associated with increased mortality, morbidity, and length of stay in the intensive care unit.

Objective

The main objectives of this scoping review are to note the available treatment options, characterize potential risk factors, and identify gaps in knowledge for vasoplegia syndrome during and after cardiopulmonary bypass.

Method

This scoping review utilized the Preferred Reporting Items for Systematic reviews and MetaAnalyses extension for Scoping Reviews (PRISMA-ScR) …


Albumin Use In Cardiopulmonary Bypass Pump Prime And Its Association With Postoperative Renal Function And Acute Kidney Injury: A Scoping Review, Hannah Talbot Apr 2026

Albumin Use In Cardiopulmonary Bypass Pump Prime And Its Association With Postoperative Renal Function And Acute Kidney Injury: A Scoping Review, Hannah Talbot

Student Works

ABSTRACT

1.Structured summary:

Background: Cardiopulmonary bypass (CPB) is associated with significant hemodilution, inflammatory activation, and alterations in renal perfusion, all of which may contribute to postoperative acute kidney injury (AKI). Albumin is frequently used as a component of CPB pump prime due to its oncotic properties and potential to mitigate fluid shifts and support intravascular volume. However, the extent to which albumin-containing priming solutions influence postoperative renal outcomes remains unclear.

Objective: This scoping review aimed to map the available literature examining the use of albumin in CPB pump prime and its reported effects on renal function and the incidence …


Clinical Applications Of Topical Platelet-Rich Plasma In Cardiac Surgery: A Scoping Review, Jaron M. Davis Apr 2026

Clinical Applications Of Topical Platelet-Rich Plasma In Cardiac Surgery: A Scoping Review, Jaron M. Davis

Student Works

Background: Postoperative wound complications persist as a significant challenge within adult cardiac surgery. Deep and superficial sternal wound infections, along with complications at saphenous vein harvest sites, are linked to increased morbidity, extended hospital stays, and substantial healthcare expenses. Topical platelet-rich plasma (PRP), commonly known as platelet gel, has been suggested as a biologically active adjunct that may facilitate tissue repair and mitigate postoperative complications. While PRP has garnered attention in surgical practice, the overall scope and consistency of the supporting evidence in cardiac surgery remain ambiguous.

Objective: The purpose of this scoping review is to map and describe the …


Goal-Directed Perfusion Strategies And Postoperative Acute Kidney Injury: A Scoping Review, Austin Davis Apr 2026

Goal-Directed Perfusion Strategies And Postoperative Acute Kidney Injury: A Scoping Review, Austin Davis

Student Works

Background: Acute kidney injury (AKI) remains a frequent and clinically important complication following cardiopulmonary bypass (CPB). Goal-directed perfusion (GDP) strategies—most commonly targeting indexed oxygen delivery (DO₂i) and/or other hemodynamic and metabolic parameters—have been proposed to reduce renal injury by improving renal oxygenation and perfusion during CPB.

Methods: A Preferred Reporting Items for Systematic Reviews and Meta-Analyses – Scoping Review (PRISMA-ScR) compliant scoping review identified 28 adult CPB studies evaluating GDP strategies and postoperative AKI outcomes.

Results: Maintenance of indexed oxygen delivery (DO2i) above critical thresholds and minimizing hemodilution were consistently associated with reduced AKI.

Conclusion: GDP strategies centered on maintaining …

Alternative Anticoagulation Strategies For Heparin-Intolerant Patients Undergoing Cardiopulmonary Bypass: A Scoping Review Of Patient Outcomes, Zachary Nelson

Student Works

Background/Introduction: Heparin intolerance, most notably heparin-induced thrombocytopenia (HIT), presents a major clinical challenge during cardiopulmonary bypass (CPB), where systemic anticoagulation is essential for safe circulation through the extracorporeal circuit. While several alternative anticoagulants have been described, there is limited consensus regarding their safety, dosing, and outcomes. The objective of this study was to map existing evidence describing alternative anticoagulation strategies for heparin-intolerant adult patients undergoing CPB and to summarize reported patient outcomes, dosing strategies, and intraoperative management considerations.
