Module 5 Pediatric Cardiac Disorders Fetal Circulation What is the main route of blood flow through the fetal heart? Fetal Circulation Why does the blood flow in that route? Fetal Circulation What is the secondary route of circulation? And third route? Fetal Circulation
What is the main route
of blood flow
through the fetal heart?
Why does the blood
flow in that route?
What is the secondary route of circulation?
And third route?
What is the stimulus for the change in circulation?
What Happens after
the Umbilical cord is
1. Decreased pulmonary vascular resistance
Increased pulmonary blood flow
Closure of ductus arteriosus
2. Increase pressure in left atrium, decrease pressure in right atrium
Closure of foramen ovale
How would the nurse recognize digitalis toxicity in an infant or child?
What are the pulse rate criteria in administration of digitalis?
Infant – 100 BPM or greater
Child – 80 BPM or greater
Adolescent – 60 BPM or Greater
Measure oxygen saturations and pressure in the cardiac chambers and great arteries
Evaluate cardiac output
Patent Ductus Arterious
Atrial septal defects
Ventricle septal defects
During cardiac catheterization the occluder is placed in the
Surgical repair with a patch inserted
When is surgery
Pulmonic stenosisTetralogy of fallotTransposition of the great arteriesTruncus arteriosus
Tetralogy of fallot
Four defects are:
a. Tissue oxygen need
b. Low iron level
C. Low blood pressure
Increased Pulmonary Flow
These present the greatest risk to survival
compatible with survival unless there is a large defect present in ventricular or atrial septum.
Microorganisms grow on the endocardium, forming vegetations, deposits of fibrin, and platelet thrombi. The lesion may invade adjacent tissues such as aortic and mitral valves.
A systemic inflammatory (collagen) disease of connective tissue that usually follows a group A beta-hemolytic streptococcus infection.
This disorder causes changes in the entire heart (especially the valves), joints, brain, and skin tissues.
Erythrocyte sedimentation rate
What additional laboratory test helps to confirm the diagnosis of Rheumatic Fever ?
Multisystem vasculitis – inflammation of blood vessels in the body especially the coronary arteries with antigen-antibody complexes.
