Q

What is the surgical treatment option for ASD?

Study These Flashcards
A

Surgical treatment: open repair with cardiopulmonary bypass before school age

mam jez lecture PLACEMENT OF PATCH same with VSD

22
Q

What important teaching should be provided to families regarding small ASD defects?

Study These Flashcards
A

A: Small defects may spontaneously close, and regular follow-up is important.

23
Q

What is the non-surgical intervention for closing an ASD?

Study These Flashcards
A

A: The defect can be closed using devices during a cardiac catheterization procedure.

24
Q

Why might surgical repair of ASD be preferred for some patients before they reach school age?
.

Study These Flashcards
A

A: Surgical repair is often recommended to prevent long-term complications such as pulmonary hypertension

25
What should be included in nursing education for families about post-surgical care for ASD repair?
Provide information on monitoring for signs of infection, activity restrictions, and follow-up appointments after open repair surgery.
26
In patients with ASD, why should nurses be vigilant for signs of respiratory infections?
A: Frequent respiratory infections are common in ASD due to increased pulmonary blood flow, and they should be managed promptly to avoid complications. H-heart failure & pulmonary HTN O-often respi infection L-low growth and weight E-extra heart sound S-stroke
27
main cause of Patent Ductus Arteriosus (PDA)
A: Failure of the fetal ductus arteriosus to close completely after birth.
28
direction of abnormal blood flow in Patent Ductus Arteriosus
Blood flows from the aorta back to the pulmonary artery and lungs.
29
How does PDA affect the left ventricle?
It increases the left ventricular workload.
30
DOC that stimulates closure of ductus in premature infants and some newborns
prostaglandin Synthetase inhibitors such as INDOMETHACIN
31
What is a characteristic heart sound associated with PDA?
loud machine-like murmur. Loud systolic murmur – VSD Machinery like murmur – PDA
32
What signs of congestive heart failure (CHF) might be seen in a child with PDA?
A: Poor feeding, fatigue, splenomegaly, poor weight gain, tachypnea, and irritability.
33
DOC to close a Patent Ductus Arteriosus in premature infants or some newborns
INDOMETHACIN (prostaglandin inhibitors) A: Ibuprofen or Indomethacin, which are prostaglandin inhibitors.
34
What are s/sx of Patent Ductus Arteriosus?
1.Cardiac 2.Heart Failure 3.Continous Machine-like murmur 4.Wide pulse pressure 5.Endocarditis 6.Activity Intolerance 7.Lungs 8.Low weight
35
What is a common non-surgical treatment option for PDA in premature infants?
A: Administration of prostaglandin synthetase inhibitors to stimulate closure of the ductus.
36
In PDA, does less than 5cm hole has effect?
naurr.
37
Anatomical defect in Coarctation of the Aorta?
A localized narrowing of the aorta | which can occur proximal to, at, or distal to the ductus arteriosus
38
Characteristic blood pressure finding in patients with Coarctation of the Aorta?
A: Elevated upper-body blood pressure, leading to symptoms like headache and vertigo. | HTN @ upper extremities
39
COA pathognomonic sign
* Bounding radial pulse * Absent femoral pulse.
40
What common symptoms might result from Coarctation of the Aorta affecting circulation?
A: Epistaxis (nosebleeds), headache, fainting, and lower leg cramps.
41
What medical therapy is typically used to manage congestive heart failure symptoms in Coarctation of the Aorta?
Digoxin and diuretics are used to reduce the severity of congestive heart failure caused by hypertension. | To reduce the severity of the congestive heart failure from hypertension
42
SURGICAL treatment- Coarctation of the Aorta
BALLOON ANGIOPLASTY
43
What surgical procedure is performed to correct Coarctation of the Aorta?
END-TO-END ANASTOMOSIS | narrowed portion of the aorta is removed, and the two ends are anastomos
44
What are some typical signs or symptoms related to the lower body in Coarctation of the Aorta?
A: Lower leg cramps and fainting due to decreased blood flow to the lower body.
45
What is the main anatomical defect in Pulmonary Stenosis?
Narrowing at the entrance to the pulmonary artery.
46
What is the extreme form of Pulmonary Stenosis called, where no blood flows to the lungs?
A: Pulmonary atresia, where there is total fusion of the commissures.
47
Common symptoms in newborns with severe Pulmonary Stenosis?
* Cyanosis * signs of congestive heart failure (CHF).
48
mild Pulmonary Stenosis present?
may be asymptomatic.
49
surgical treatment - Pulmonary Stenosis
* infant 1. Valvuloplasty or TRANSVENTRICULAR VALVOTOMY * child 1. PULMONARY VALVOTOMY
50
What is the surgical treatment option for infants with Pulmonary Stenosis?
Transventricular valvotomy
51
What surgical procedure is commonly performed for** older children **with Pulmonary Stenosis?
Pulmonary valvotomy
52
Pulmonary Stenosis SURGICAL TREATMENT
SURGICAL TREATMENT * In infants, transventricular valvotomy * In children, pulmonary valvotomy
