FINAL CARDS Flashcards
(206 cards)
A pt presents with acute intracranial hemmorage, what is the approach to lowering the BP
If the BP is above 220, start lowering tx with IV infusion
If below 220 the lower BP to less than 140 (can cause harm)
A pt presents with acute (less than 72 hrs) with ischemic stroke
What is the BP lowering Tx approach
Does the pt qualify for thrombolytics?
Yes? Then lower BP to less than 185/100-110 in the first hour and before starting thrombolytics then maintain BP less than 180/105 for the first 24 hours.
No?
Is the SBP above 220?
No? Then restart pts BP medication
yes? Lower BP by 15% during the 1st 24hrs
What are the acyanotic congenital heart dz
VSD/ASD (without eisnmenger)
PFO
PDA
Coart
All these are L to R shunts (high pressure to low pressure)
What are the Cyanotic Congenital Heart Dz
Transpo of the Great vessels (incompatible with life)
Truncus Arteriosis ( basically an overriding aorta)
Hypoplastic L heart (pt never develops a left ventricle)
Tetralogy of fallout ( VSD +PS+RVH+Overriding Aorta)
Pentalogy of Fallot (tetra +ASD)
Total Anomolous Pulm Venous return
All are naturally R to L shunts
What are the common risk factors for Congeintal Heart Dz
Genetics Rubella exposure Alcohol while pregnant Multi fetal births DM HTN Connective Tissue Disorders Mood D/o Epilepsy Thyroid D/o
You are evaluating an infant and you heard a harsh systolic murmur over the left scapula or left shoulder
Think >?./
Coart of the aorta
These pts will have life long HTN problems
You are listening to lung sounds and you hear an ejection/ Systolic murmur at the LUSB that increases with inspiration, with a Wide Split S2
Think?
PS
What is the MC obstructive Heart Lesion in Children/ Infants
AS, Harsh sys ejection murmur that radiates to the carotids. Increases with expiration, and increases with hand grip
Where is the common site for Coart to occur
Adjacent to the Ductus Arteriosis
What is the Tx appraoch to Coart (congenital)
Surgical repair, ballon angio
Life long HTN tx
You hear a fixed wide S2 split, tat first is acyanotic and later develops cyanosis, and clubbing
Think what MC congenital HDz later found in adults
ASD
ASD is a L to R shunt that eventually develops RVH and eisnmerger syndrome leading to cyanosis
At what age does the PFO close
At 6 months
A new born presents with HF s/s , poor growths, and has an increased risk of infections,
You hear a pansystolic murmur at the LSB
Think
VSD
These pts present acyanotic and then later can develop eisnmerger syndrome and become cyanotic
Increased R Vent pressure lead to what looks like CHF with Edema in the periphery
O se the shunt reverse these pts has a large apical pulse and pulm congestion
With labored RR, grunting, rib contractions
CXR will show Cardiomegaly and prom pulm arteries
EKG LAE, LVH leading to RVH
What is the Treatment approach to VSD in infants
Is its small and AS/s then f/u at 8-10 weeks
Then again at 12 months
Most will spont. Recovery
If its large
Then Diet intervention 2 prevent wt gain
Dietetics, the ACEI, and SRGRY if PAP is greater than 50mmHg
pts with need ABX prophylaxis for dental and RR procedures for any produced with in 6 months of SRGICAL repair
You hear a continous machine like murmur In a new born, with Lower extremity cyanosis yet uppers are not
What natural pathway of circulation has not closed
PDA
Which normally closes at 1 wk
Leads to LHF to RHF to eisnmerger syndrome leading to LE cyanosis and UE acyanotic
Pt will also have a wide pulse pressure
Tx with SRGY ligation
What is the MC cyanotic Heart lesion
Tetralogy
What are the 4 findings in tetralogy
- VSD
- RVOO (PS)
- RVH
- Overriding aorta
- ASD? =pentalogy
PS leads to RVH leading to Eisnmerger through the VSD, and Cyanosis
Describe the murmur of PS
Sys ejection murmur at the LUSB
With a loud s2 sound
+/- systolic thrill
Prominent RV pulse
A mother says her baby gets cyanotic but then does a squat and is able to keep playing
What is this ?>
Text spell seen in tetralogy
Then squat increases SVR which increase LV pressure
Causing reversal of eisnmergers and reduces cyanosis
What are the later findings of tetralogy in infants
Poor feeding Tets spells Increase HR and BP Cyanosis Syncope Poor growth And late puberty
You see a “boot shaped” heart on CXR
With a right aortic arch
Think
Tetralogy
How do you Dx tetralogy
Gestalt and ECHO!
What is the immediate Tx approach to a baby with tetralogy
Place the knees againt the chest
Start O2
And give fluid bolus
May need to treat HF with morphine, propranolol/ esmolol and then SRGY
(With out SRGY 50% DIE)
What are the major bad outcomes of Tetrology
Pulm regurgition, RV enlargement, RV dysfunction
Aortic root dilation
High risk of developing infectious endocarditis
