Therapeutic Plasma Exchange To Alleviate Ventricular Tachycardia After Diphenhydramine Ingestion, Kaushal Dosani, Lejla Music Aplenc, Stephen Pfeiffer

Research Days

Background: The Covid-19 pandemic has adversely affected the mental health of children causing an increased incidence of suicide attempts. Diphenhydramine is a common household medication and is frequently ingested by children. Toxic doses of diphenhydramine can affect the cardiovascular and central nervous system. In the heart, diphenhydramine blocks fast sodium channels and potassium channels which can result in conduction abnormalities including sinus tachycardia, widening of QRS duration, ventricular tachycardia and torsades de pointes. Massive ingestion can cause severe cardiovascular collapse which may require ECMO support

Objectives/Goal: To describe a novel method of clearing highly protein-bound diphenhydramine molecules from circulation after …

Safety, Timing And Outcomes Of Early Postoperative Cardiac Catheterization Following Congenital Heart Surgery, Karoline Krzywda

Research Days

Watch recording of live presentation

Background: Early postoperative ( < 6weeks) cardiac catheterization (EPOCC) has been considered high risk and often delayed. Recently, the safety of EPOCC has been demonstrated. The optimal timing of catheterization and its outcomes in struggling postoperative patients remains uncertain.

Objective: To describe EPOCC in our center and its impact on length of stay (LOS), number of mechanical ventilation days, number of ECMO days, and catheter-based interventions.

Methods: This is a retrospective cohort study of patients who underwent cardiac surgery between 01/01/2010 and 12/31/2019 and EPOCC within 30 days after surgery. Cohorts were early EPOCC (≤72 hr) vs late EPOCC ( >72 hr). Data on timing, indication, and complications of EPOCC; days of mechanical ventilation and ECMO; and CICU/total hospital LOS were collected. Data was analyzed using chi-square and Student’s t-test, …

Pediatric Pulmonary Artery Aneurysms Causing Pulmonary Hemorrhage: A Case Of Transcatheter Intervention While On Va Ecmo Support, Igor Areinamo

Research Days

Background: The incidence of pulmonary artery aneurysm (PAA) in children remains unknown. There are few reports of a transcutaneous interventional approach to address this type of pathology. Management of PAAs while on VA ECMO has not been described in pediatrics.

Objectives/Goal:

Methods/Design:

Case: 9-year-old previously healthy male presented with MRSA associated ARDS and sepsis requiring urgent VA ECMO cannulation. Chest CT done on ECMO day 22 showed development of right sided PAAs. Patient had an episode of significant pulmonary hemorrhage. Angiogram demonstrated two fusiform right PAAs, one of which had ruptured and was bleeding into the lung parenchyma. Patient had …

Pre-Implementation Of A Fontan Post-Operative Clinical Pathway: Summary Of 2016 Pdsa Cycles, Sarah M. Lagergren, Bryan Beaven, Suma Goudar, Megan Jensen

Posters

Background/Introduction: Post-operative hospitalization for the Fontan procedure tends to have an extended hospital length of stay (LOS). From 2013-2014, the average LOS at Children’s Mercy for the Fontan procedure is 14 days, whereas the U.S. national reported average is 11 days. Post-operative management of this patient population is often caregiver dependent. It has been theorized that developing a more standardized post-operative management regimen tailored specifically toward the unique physiology of Fontan patients may be able to improve outcomes and decrease LOS.

Methods: A review of literature was performed and revealed three pediatric institutions have published their post-operative Fontan care guidelines. …

A Quality Improvement Project For The Evaluation And Management Of Possible Necrotizing Enterocolitis In Single Ventricle Patients, Laura Miller-Smith, Jennifer Flint, Lisa Laddish

Posters

Background:

Infants with single ventricle (SV) physiology are at high risk for interstage complications, including necrotizing enterocolitis (NEC). The underlying pathophysiology and age at presentation differs from NEC literature described in premature infants, making NEC in SV patients challenging to diagnose and treat. We perceive significant variability in the approach to possible NEC in SV patients at our institution.

Aims:

To identify variability & standardize the approach to management of NEC

To create a management algorithm for diagnosing and treating NEC

Methods:

After review of current practice and review of medical literature, an algorithm to guide medical decision making specific …

Obstacles To Introducing A Post-Operative Feeding Protocol In The Single Ventricle Population, Lisa Laddish, Laura Miller-Smith, Jennifer Flint

Objective:

To decrease the morbidity associated with feeding complications by implementing a post-operative feeding protocol for infants with single ventricle physiology

B-Type Natriuretic Peptide (Bnp): A Potential Biomarker For Extubation Failure In Infants Following Cardiac Surgery, Jennifer Flint, Lori Erickson, Dawn Tucker, Erica Molitor-Kirsch

Posters

Background: BNP is a hormone released from the cardiac ventricles in response to increased pressure and volume overload1 and is an important biomarker in heart failure. Following congenital heart surgery, elevated BNP levels correlate with longer duration of mechanical ventilation, low cardiac output syndrome, and increased ICU length of stay2-4 Mechanical ventilation (MV) has an exaggerated impact on cardiopulmonary interactions in children with myocardial dysfunction, and extubation readiness can be difficult to determine post-operatively following congenital heart surgery.

Hypothesis: An increase in post-extubation BNP levels can predict extubation failure and the need for reintubation within 48 hours.

Methods:

Design: prospective, …
