Q

Post op pain assessment

A

Give opioids with caution as they may mask anesthetic responses
Document pain response 5-10 min after IV injection
Around the clock pain meds are best
No knee gatch or pillows under knees
Don’t massage calves

23
Q

Opioid overdose

A

Prepare to administer naloxone hydrochloride (Narcan)* in a dose of 1 to 2 mg IV.
• Repeat naloxone every 2 to 3 minutes up to 10 mg, as needed, depending on the patient’s response.

24
Q

Post op diet to promote wound healing

A

High in protein, Vitamin C, zinc, and calories

25
Q

Cardiac Output

A

amount of blood pumped from the left ventricle each minute
CO=Heart Rate X Stroke Volume
Normal CO is 4-7 liters/minute

26
Q

Stroke Volume

A

amount of blood ejected by the left ventricle during each contraction.

27
Q

Determined by the amount of RESISTANCE the ventricles must overcome to eject blood through the semilunar valves into the peripheral blood vessels

A

Afterload

28
Q

Determined by the VOLUME of blood returning from the venous and pulmonary systems

A

Preload

29
Q

Is the FORCE of cardiac contraction independent of preload

A

Myocardial contractility

30
Q

cardiac output X peripheral vascular resistance

A

Blood Pressure

31
Q

RETURNS the blood to the right side of the heart

A

Veins

32
Q

Deliver oxygen and nutrients

A

Arteries

33
Q

Pumps blood out of heart

A

Left Ventricle

34
Q

More cardio deaths

A

American Indians, Alaska Natives

35
Q

Triglycerides desired range

A

<150

36
Q

HDL desired range

A

> 40

37
Q

LDL desired range

A

<100 in moderate risk pts

38
Q

Cardiac Cath Surgery

A

Performed in “Cath Lab”
Local Anesthesia
Instruct patient to report chest pain or pressure
Catheter inserted through:
Femoral VEIN to superior vena cava (Right heart only)
Basilic VEIN to superior vena cava (Right heart only)
Femoral or brachial ARTERY up the aorta into left heart

39
Q

Echocardiography

A 
Non-invasive
Risk free
Use of ultrasound waves to assess cardiac structure and mobility
Cardiomyopathy
Valvular disorders
Pericardial effusion
LV function
Ventricular aneurysms
40
Q

Transesophageal echo

A

Ultrasound transducer placed immediately behind the heart in the esophagus or stomach
Allows for a good look at the posterior cardiac structures

41
Q

Splinter hemorrhages

A

Infective endocarditis

42
Q

Often transmitted as a single-gene autosomal dominant trait

A

Hypertrophic cardiomyopathy

43
Q

Usually from rheumatic carditis (developing countries) or is often congenital in industrialized countries causing valve thickening by fibrosis and calcification

A

Mitral Stenosis

44
Q

Etiology varies-Marfan, family tendency, other congenital cardiac defects
Valve leaflets enlarge and prolapse into LA during systole
Usually benign but may progress to mitral regurgitation

A

Mitral Valve Prolapse

45
Q

Most common in US and in all countries with aging populations
Disease of “wear and tear”, congenital, rheumatic disease, atherosclerosis
Aortic orifice narrows
Obstructs LV outflow during systole
Resistance leads to LV hypertrophy
Cannot meet demands of body during exertion
LV fails
Blood back up into LA-lungs-RHF
When valve surface 1cm or less EMERGENCY SURGERY!

A

Aortic Stenosis

46
Q

Collect family history
Ask about rheumatic fever or endocarditis-obtain date of disease and whether or not patient used antibiotics
IV drug abuse?
Clue to infective endocarditis
Activity level
Vital signs, auscultation, palpation
-avoid MRIs, wear medicine alert bracelet

A

Valvular Heart Dz

47
Q

Accomplished with cardiac bypass during open heart surgery
Surgeon visualizes valve
Removes thrombi from atria
Incises fused leaflets
Debrides calcium from the leaflets, widening the orifice

A

Direct Open Commissurotomy

48
Q

Mitral regurgitation
Surgeon to make annulus (valve ring) smaller
May repair leaflets
Valve can close completely
Regurgitation eliminated or markedly reduced

A

Mitral Valve Annuloplasty (reconstruction)

49
Q

Sensitivity Response
Develops after upper respiratory tract infection with group A beta-hemolytic streptococci
-pleural friction rub

A

Rheumatic Carditis

50
Q

Replacement of myocardial tissue with fibrous and fatty tissue
1/3 of patients also have left ventricular disease
Familial association
Some have symptoms, others do not

A

Arrhythmogenic Right Ventricular Cardiomyopathy (dysplasia)

51
Q

Restrictive filling during diastole

A

Restrictive Cardiomyopathy

52
Q

Heart Transplant Requirements

A 
Life expectancy less than 1 year
< 65 years of age
Normal or slightly increased PVR
Absence of infection
Stable psychosocial status
No evidence of current drug or alcohol abuse
53
Q

Monitor the patency of the graft by checking the extremity every 15 minutes for the first hour and then hourly for changes in color, temperature, and pulse intensity.
Compare the operative leg with the unaffected one. If the operative leg feels cold; becomes pale, ashen, or cyanotic; or has a decreased or absent pulse, contact the surgeon immediately!
May require emergency thrombectomy

A

Graft Occlusion

54
Q

Initiate treatment promptly
Heparin therapy
Angiography
Surgical thrombectomy or embolectomy
