- no lifting higher then 90
184
what are the populations that have an increase risk in having a sternal infection
1) women
2) diabetes
3) obesity
4) bilateral mammary artery harvesting
5) re operation procedures
6) increased blood product requirement
185
a 0 on the sternal instability scale
clinically normal sternum - no detectable motion
186
a 1 of the sternal instability scale
minimally separated sternum. slight increase in motion when special testing
187
a 2 on the sternal instability scale
partially separated sternum - moderate increase in movement at special testing
188
a 3 on the sternal instability scale
completely separated sternum- marked increase in motion when special testing
189
what are ACSM guidelines for movement with sternal precautions
- 5-8 weeks: lifting should be limited to 5-8 lbs
- ROM exercises and lifting 2-3 lbs
- pts adversed to limit ROM within the onset of feelings of pulling on the incision or mild pain
190
Post operative recommendations after CABG
- avoid stretching both arms backwards at the same time(10 days)
- keep elbows close to the body (8weeks)
- move within a pain free range
- use leg rolling when getting out of bed
- self hug when coughing
- wear supportive bra with big breasted women
191
PT considerations for post op CABG
- monitor vitals
- monitor cognition
- signs of PICS
- lab values for anti-coagulation and infection
- lines and tubes
- infection control and healing promotion
- deep breathing, coughing and pulmonary hygiene
- functional mobility
- discharge planning
192
what is an abdominal aortic aneurysm
dilation of the abdominal aorta 50% larger than normal due to a weekend vessel wall
193
risk factors for AAA abdominal aortic aneurysm
- smoking
- male
- age
- Caucasian
- atherosclerosis
- family history
- other aerial aneurysms
- connective tissue disorders
- prior hx of aortic dissection
- prior hx of aortic surgery or instrumentation
194
a ruptured AAA
high mortality rate. more common in women
195
pain location of someone with AAA
abdominal, back, flank, pelvis, groin, or thigh
may present with general malaise
196
AAA treatment
1) abdominal aortic aneurysmectomy
2) endovascular repair
197
reasons for getting a heart transplant
- end stage heart disease
- NYHA class 3 and 4 or AHA stage D uncompensated
- poor quality of life
198
absolute contraindications for heart transplant
- organ or blood malignancy in the past 5 years
- substance abuse within the last 6m0
- HIV
- SLE, Sarcoidosis, Amyloidosis, with multisystem involvement still active
- irreversible hepatic or renal dysfunction
- COPD
- pulmonary HTN
- Cerebrovascular disease
- Hep B or C infection
199
relative heart transplant contraindications
- over 70
- active infection
- active peptic ulcer
- severe DM with end organ damage or poor glycemic control
- severe PVD limiting rehab and revascularization not possible
- AAA
- BMI over 35
- HTN
- dementia or poor social support
200
what are the surgical techniques for heart replacement
1) heterotypic heart transplantation - piggyback
2) total transplantation
3) biatrial technique
4) orthotopic/biatrial
201
heterotypic heart transplantation - piggyback
native heart is not removed
donor heart is connected to the native heart via the atria
202
biatrial technique
biatrial anastomoses whereby donor and recipient atrial cuffs are sewn together
203
orthotopic/biatrial
leaves the recipient SA node intact and functional while donor heart SA is denervated
- 2 separate P waves will be seen
204
PT considerations for a heart transplant pt
- infection control
- aerobic endurance
- vitals - ex BP
- denervated heart: extended warm up and cool down, use RPE, SV lower then normal
205
heart transplant rejection signs and symptoms
- low grade fever
- myalgia and fatigue
- Hypotension with activity by hypertension at rest
- decreased exercise tolerance and dyspnea
- arrhythmias
- weight gain
- decreased fluid output
206
PT dosing considerations post heart transplant
- aerobic power at q year 40-50% of age matched norms
- peak ex CO 30-40% lower then age matched controls
- innunosuppressant drugs have effect on skeletal muscle
