Peds Exam 2 Flashcards
pre-procedure for cardiac cath
-accurate height and weight
-allergy history (especially to iodine)
-NPO for 6-8 prior
-locate and mark distal pulses
post-procedure for cardiac cath
-position affected leg STRAIGHT
-check temperature bilaterally
-ASSESS INSERTION SITE AND PRESSURE DRESSING
-assess peripheral perfusion
disorders with increased pulmonary blood flow
patent ductus arteriosus (PDA), atrial septal defect (ASD), and ventricular septal defect (VSD) in these defects, blood is shunted from high pressure left side to low pressure right side
patent ductus arteriosus (PDA)
passageway (ductus arteriosus) between the aorta and the pulmonary artery remains open (patent) after birth
treatment for patent ductus arteriosus (PDA)
Indomethacin (Indocin)
atrial septal defect (ASD)
an opening in the septum separating the atria; may close spontaneously, if it doesn’t surgical intervention is needed
ventricular septal defect (VSD)
an opening in the septum separating the ventricles; may solve spontaneously, but if VSD is severe enough HF can result
Disorders with decreased pulmonary blood flow
Tetralogy of Fallot, Tricuspid atresia; pressure of right heart is high so desaturated blood from right side shunts to left
What are the 4 defects of Tetralogy of Fallot?
-Pulmonary stenosis
-ventricular septal defect
-overriding aorta
-right ventricular hypertrophy
key symptom of tetralogy of fallot
Tet spells manifested as increased cyanosis, hypoexemia, agitation comes with crying feeding or defacating
for hypercyanotic spells
-calm the child
-knee to chest postion
-administer O2
-administer morphine
-IV fluids
interventions for tetralogy of fallot
KNEE TO CHEST POSITION; helps to improve pulmonary blood flow by increasing systemic vascular resistance
tricuspid atresia
Tricuspid valve orifice fails to develop; right ventricle is hypoplastic
in tricuspid atresia, what must remain open to maintain minimally adequate oxygenation?
foramen ovale and PDA
Tricuspid Atresia Treatment
Prostaglandin (PGE) to maintain patency of PDA, Surgical Repair
coarctation of the aorta
congenital cardiac condition characterized by a narrowing of the aorta
key symptom of coarctation of the aorta
blood pressure higher in the upper extremities and decreased in lower extremities (20mmHg or >)
intervention for coarctation of the aorta
-balloon angioplasty
-resection of narrowed aorta followed by end-to-end reanastomosis
aortic stenosis
narrowing of the aorta; resulting in decreased CO
difference in symptoms for coarctation of the aorta and aortic stenosis
coarctation of the aorta: dizzy and LEG PAIN
aortic stenosis: dizzy and CHEST PAIN
Transposition of the great vessels
a congenital abnormality where the aorta is attached to the right ventricle and the pulmonary artery to the left ventricle (this is backwards and leads to two separate blood routes)
Transposition of the great vessels presents with
significant cyanosis at birth
interventions for Transposition of the great vessels
corrective surgery performed at 4-7 days
Hypoplastic Left Heart Syndrome
underdevelopment of the left side of the heart, usually resulting in an absent or nonfunctional left ventricle
without intervention of hypoplastic left heart syndrome…
death will occur rapidly
treatment of choice for hypoplastic left heart syndrome
heart transplant
s/s of heart failure in children
-weight gain
-activity intolerance
-poor feeding
-depends on L or R side HF
medication for improved cardiac function
digoxin, ACE, B-Blockers
do not give digoxin to infants if pulse is
<90-110bpm
do not give digoxin to older children if pulse is
<70bpm
medication to remove accumulated fluid and sodium
Furosemide
Digoxin effects on heart
slows HR but deepens contractions
interventions for heart failure
-semi-fowlers
-feeding every 3 hours and have infant take required food in within a 30 minute time period
-neutral environment to prevent cold stress
-cool humidified oxygen
rheumatic fever
inflammatory disease that may develop as a delayed reaction to insufficiently treated group A beta-hemolytic streptococcal; effects connective tissues of the heart, joints, skin, blood vessels, CNS
rheumatic fever can manifest
2-6 weeks after strep throat
