Q

What is the problem with stents in coronary angioplasties?

A

Stents collect plaque and blockage can reappear

Drug eluting stents fix this problem by releasing drugs from the stent that stops blockages from occuring

Q

what are complications of an IABP?

A

the balloon goes through the aorta which can block BF to the extremities, so check capillary refill and pulses

can also cause damage to the vessel itself - cause arterial thrombus

25
What is an impella heart pump?
same precautions and complications as IABP, but it goes into left ventricle and sucks up blood and pushes it into aorta to decrease workload of heart
26
what is the purpose of percutaneous procedures?
reestablish blood supply!
27
what is the most commonly replaced valve?
aortic valve
28
true or false: most of the time physicians seek to repair the mitral valve instead of replace it
true why? because then they wont need blood thinners for the rest of their life. They would if it was a replacement the aortic valve cannot be repaired, its replaced by pulmomnary valve
29
What is the ross procedure?
using pulmonary valve to replace aortic valve then pulmonary valve is replaced by donor
30
true or false: tricuspid and mitral valve rarely need to be replaced
true
31
What are the advantages of a bioproshesis instead of a mechanic valve?
reduces risk of stroke Only patients with a mechanical valve will need blood thinners for rest of life!
32
why is it hard/impossible to repair the aortic valve
pressure is too high
33
what is the purpose of an annuloplasty?
flexible ring placed around mitral valve for support, reinforced annulus prevents dilation of valve
34
valve repair procedures are usually done how?
minimally invasive percutaneous procedure where a catheter goes through femoral vein
35
what is the risk of catheter based valve repair procedures
risk of bleeding fatigue may be issue usually patients can go home from hospital after a day or 2
36
what is "something to think about" when a patient is coming off of a heart/lung machine
fatigue may be issue
37
True or false: Mitral valve repair typically does better than replacement
True Also: Patients with repair dont have to use blood thinners for as long
38
what is the problem with anticoagulation medication for long periods of time?
bleeding
39
What is a cardiac ablation?
destroys ectopic cells in myocardium that cause arrhythmias produces scar on myocardium using ablation catheter typically radiofrequency or cryotherapy note: very good for a-fib, can be used for v-fib too
40
What needs to happen before a cardiac ablation procedure
electrophysiological mapping to find the arrythmia
41
what is a risk of cardiac ablation?
it may end up causing another arrythmia because the inflammation response
42
Cardiac ablation patients typically need ____ days of rest
4-7 days of rest
43
what is a pace maker primarily for?
slow rhythm and heart blocks OR fast rhythm in UPPER chamber
44
whats the most important thing to know about a patients pacemaker
what their particular pace maker is for 1. always works to maintain regular rate 2. only works if rate is below certain amount 3. or if they are used stop the atrias from going to fast
45
what are the 2 kinds of pace makers
Unipolar- one electrode (- at myocardium and + at pacemaker box) bipolar (Biventricular) - 1 lead on right atrium, 2 at ventricles, (3 total leads)
46
pacemaker precautions for 4 weeks
no ROM of UE > 90 degrees, it might stretch the incinsion or move the lead
47
what is an Implantable cardioverter defibrillator for?
Used to correct life threatening arrythmias (designed for fast ventricular arrythmias)
48
What will you see on an ECG if the patient has a pacemaker?
Pacemaker spikes if spike is infront of P-wave- the pace maker is working at atria If spike is infront of QRS- pace maker is working at ventricles
49
If a patient comes to PT and says theyve recently been shocked by their ICD what do u say
go talk to your physician before PT
50
What is important to know for a patient with a pacemaker/ICD
Need to know at what heart rate their device is designed to deploy stay 10-20 BPM below that
51
Endocardial vs epicardial pace makers
endocardial- inside the right atrium and ventricle via access through a large vein (transvenous) epicardial- more often used in patients undergoing heart surgery often only used for temporary pacing
52
If a patient has a surgically placed pace maker what is a common precaution associated with this
no raising arm overhead no contact sports no lifting more than 10lbs incinsion is made in pec major and minor
53
What is a temporary ICD (vest)
patient who has had an MI in the past, there is a risk of arthmyias but as the heart heals the risk of arthymia drops
54
When looking at a ECG for someone with a pacemaker, what does it mean if you see the pacemaker spike before the p wave? what about QRS?
Before Pwave- atrial pace maker before QRS- ventricular pace maker
55
Abdominal aortic aneurysm repair is indicated for aneurysm's larger than...
5cm or rapid enlargement or sudden change in characteristic of pain
56
If a patient get's an abdominal aortic aneurysm repair where there is a midline incision at the xiphoid process, what is a common precaution youll see?
No thoracic extension 4-6 weeks
57
What are patients at high risk for following an AAA surgery?
Atelectasis! lung collapse pulmonary complications because incisional pain limits inspiration
58
If a patient has an abdominal aortic aneurysm repair, what does PT need to teach them?
bronchiole hygene techniques. this patient cannot use their abdominals to huff or cough!!! no huffing or coughing! note: you can teach them how to huff later on
59
what is a bronchoscopy?
procedure using endoscope to inspect airways of lung, remove obstructions or tumors, stop bleeding
60
What is a Lung resection? What are the three types?
surgical removal of all or part of lung due to diseases such as cancer - wedge, lobectomy and pneumonectomy
61
What vitals would you watch if your pt had a lung resection?
SpO2, RR, Swann catheter
62
What is a thoracocentesis?
drains excess fluid from pleural space
63
What should you as PT focus on following a thoractomy?
Proper positioning (semi fowler upright best for lung expansion) breathing exercises, chest wall expansion exercises
64
Where is the incision for a posterolateral thoracotomy? what nerve is in this region?
T4 and scapula to 5-6th intercostal space divides the serratus anterior (SALT) makes it difficult to breathe
65
where is the incision for an anterolateral thoracotomy?
4-5th intercostal space to midaxillary line (pec major is incised, serratus anterior fibers separated)
66
What is a very common complication following thoracic surgery, specifically the anterolateral approach?
damage to the phrenic nerve causes SHOULDER PAIN (ipsilateral) position during AL surgery shoulder stabilizers are cut (SA, pec major)
67
where is the incision for a lateral thoracotomy?
near nipple line extending toward scapula
68
where is the incision for a thoracoabdominal incision?
8th,9th IC space at post axillary line to midline of abdomen transection of : lats, SA, External oblique, rectus abdominus note: with this patient you cannot activate these muscles too aggressively at first allow them to heal
69
what are post-op difficulties for thoracoabdominal incision?
-coughing -deep breathing -thoracic extension -80% experience ipsilateral shoulder pain, referred pain from phrenic nerve NO AGGRESSIVE STRETCH OR STRENGTHENING
70
T/F: Chest tubes are portable and should be monitored before and after PT treatment
T
71
Chest tube PT precautions
do not tip the collection system = results in lung collapse! treat them all as drainage tubes encourage upright positioning, ambulation, deep breathing to aid in removal of secretions
72
A video assisted thorascopic surgery is less or more invasive, allowing for what?
less invasive, no rib spreading allows for eariler mobilization, less pain, less blood loss
73
peripheral vascular procedures
used to remove plaque and reestablish BF to periphery can be surgical or translumenal angioplasty
74
What is a carotid endarectomy?
the common and external carotid have plaque removed and then are surgically closed and a bypass shunt is inserted to make sure blood gets to the head used when stenosis > 50% or 60% in asymptomatic patient
75
What is a common symptom for a patient who just had a carotid endarectomy?
the incision ins made at the SCM so they will get dizzy with head turns
76
What might you hear when auscultating the carotid artery is blocked?
brewy
77
True of false, peripheral vascular procedures and carotid endarectomies increase BP
FALSE, these open up the vessel so they dont increase BP
78
how does anesthesia affect pts respiratory fxn?
depresses breathing, alters tone and contractile patterns of the diaphragm and intercostal muscles
79
anesthesia can cause alveolar collapse which causes
intrapulmonary shunting
