Cards

Term
average number of people who die each day waiting for a transplant
Definition
22
Term
non-solid organs for transplant
Definition
skin, bone, bone marrow, veins, heart valves, corneas
Term
Werdnig-Hoffman disease
aka
what is it
Definition
aka spinal muscular atrophy
a muscle wasting condition
Term
Allograft
Definition
-homograft
-between individuals of the same species
Term
autologous
Definition
transplant within the same individual
Term
xenogenic transplant
Definition
-heterograft
-between individuals of different species
Term
allogeneic transplant
Definition
the source comes from a human leukocyte antigen (HLA) matched donor
Term
syngeneic transplant
Definition
between genetically identical members of the same species, AKA identical twins
Term
types of transplantation by location
Definition
-orthotopic homologous - replacement
-in heterotopic - "piggybacking"
Term
orthotopic homologous transplant
Definition
replacing the organ with the donor organ
Term
heterotopic transplant
Definition
leaving the original organ, but adding the donor organ at another site of the body, "piggybacking"
Term
organ donation considerations
Definition
-urgency and likelihood of benefit from transplant
-age: usually unfer 50
- smoker: less than 30 pack-years HX
-blood type compatible (hUMAN LEUKOCYTE ANTIGEN)
-no evidence of malignancy, HIV, HepB, or sepsis
-Hep C is precaution, but not contraindication
-body weight w/in 20% normal
Term
location concerns with organ transplants
Definition
preservation
-heart: 6 hours
-Liver: 24 hours
- kidneys: 72 hours
- lungs: 4-5 hours
Term
criteria for transplant recipient
Definition
-matched blood type
-body weight: w/in 20% normal
-presence of other illness
-infections (put on immunosuppressants)
-malignancy
-PVD
-non-ambulatory
-non-compliant
-ETOH abuse
-psychological stability
-family/financial support
Term
xenotransplantation advances
Definition
-used as a short term bridge
-risk rejection
-risk animal - human deisease
Term
tissue engineering advances
Definition
-lab grown tissues decreases chance of rejection
Term
medication and transplant advences
Definition
help with rejection prevention
Term
legal and ethical topics with transplantation
Definition
-embryonic stem cells
-adult (somatic) stem cells
Term
buying/selling organs, legal/ethical
Definition
selling is illegal, but offering incentive is ok for now
Term
biopsychosocial issues with transplantation
Definition
-emotional: waiting, fear, excitement
-postop: graft rejection, acceptance of organ, memory transference
Term
complications with transplantation
Definition
-surgery associated ischemia
-histocompatibility (HLA)
-Graft vs. host disease
- graft rejections
Term
types of graft rejection by time
Definition
-hyperacute - minutes or hours after SX
-acute or late acute - days to years
- chronic - months to years
Term
complications of immunosuppression
Definition
-increased susceptibility to infection
-cancer
- nephrotoxicity and hepatotoxicity
-osteoporisis
- Hypertension
- tremor
- suppressed wound healing
- diabetes
Term
solid organ transplants complications
Definition
those who require transplant have chronic disease pre-op, leading to
-muscle weakness
-possible prolonged hospitalization
- fatigue,
-extended confinement to bed, room, house
-poor ambulatory skills
- poor breathing
- inability to clear resp. secretions
Term
benefits of physical therapy pre-hab
Definition
faster recovery
better outcomes
-can qualify someone as a recipient
Term
post operative physical therapy benefits
Definition
-start ASAP
- helps with balance
-addressed weakness, poor endurance, poor flexibility, decreased ROM
- loss of independent ambulation, poor bed mobility
- inability to perform transfers -> skin breakdown, edema
- breathing re-training, airway clearance
-resistance exercise increases bone density
Term
rehab monitoring while still in the ICU
Definition
-heart rate
- rate of perceived exertion scale
- blood pressure
- dyspnea index
- signs/symptoms of fatigue
- lab values
Term
rehab monitoring after the ICU
Definition
-increased MET levels
- focus on independence in ADLs
- increase endurance(4-5 days/week, 30 min)
-progression of exercises and guidelines for termination of exercise
- preparing for discharge
-patient education: know signs/symptoms
-HEP
-quality of life
Term
MET
Definition
resting metabolic rate
Term
living after transplant
Definition
-avoid contact sports
-monitor for hypertension, myopathies, neuropathies
Term
hematopoietic cell transplntation
Definition
transplantation of multipotent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood.
Term
indications for hematopoietic cell transplantion
Definition
-malignancies
-bone marrow failure
-genetic diseases
-auto immune disease
Term
hematopoietic cell transplantation complication
Definition
-infection
-liver disease
-graft vs host disease
-fatigue
-effects of chemotherapy
Term
kidney transplant
-function
-occurrence
-common complication
-survival rate
Definition
-kidneys filter waste
-the most common transplant
-complications include graft rejection, infection, or dysfunction
-5 year survival rate has increased to 90% today
Term
liver transplant
-function
-living vs. deceased donor
-complication
Definition
-liver processes drugs, fats, carbs, and produces platelets for clotting
-living donor, you can take part of the liver and it grows back
-deceased donor - you can take the whole thing
-complications: infections, failure
Term
liver transplant causes
Definition
-non-cholestatic cirrhosis
-cholestatic live disease/cirrhosis (Crohn's, ulcerative colitis)
-biliary atresia (blockage)
-acute hepatic necrosis (hep C and B)
-metabolic disease
-malignant neoplasms
-cystic fibrosis
Term
sovaldi
Definition
drug that cures Hep C
Term
heart transplantation
-causes
Definition
-cardiomyopathy
-coronary artery disease
-congenital heart disease
-valvular heart disease
-retransplant/graft failure
-cancer
Term
heart transplantation
-cpmplications
Definition
failure
rejection
infection
Term
heart transplantation heart rate response
Definition
due to cutting vagas nerve, which regulates SA nodes tendency to fire at 100bpm
-elevated heart rate at rest
-blunted heart rate response to exercise
-use RPE
Term
Ventricular assist device
Definition
-can be destination or bridge
-continuous flow means no pulse rate
Term
lung transplant
-function
-preservation
-donor (live vs deceased)
-
Definition
-function in gas exchange

Definition
-emphysema
-cystic fibrosis
-pulmonary fibrosis
-pulmonary hypertension
-occupational inhalation
-burns/trauma
Term
lung transplant complications
Definition
-denervation mean no cough reflex, diminished mucociliary function, which contributes to frequency of pulmonary infection
-graft failure
-infection
-rejection
