Basic Flashcards
Extravasation
vesicant agent infiltrates into the tissue surrounding the vein and causes cellular damage or tissue destruction
irritant agent
medication that can cause pain and inflammation at the administration site or along the path of the vein that is used
treatment protocol
a “recipe” that defines the drug combinations that will be used to treat a specific cancer, including:
- standard dose of the drug
- the administration frequency of the drug
- the time interval between drugs
- the treatment for side effects
- routine monitoring
- the laboratory tests
Infections in BMT setting
results from:
1. neutropenia
2. depressed T- and B-1 lymphocyte function
3. disruption of anatomic barriers
4. immunosuppressive agents used to manage GVHD
Most common sites:
1. GI tract
2. oropharynx
3. lung
4. skin
5. indwelling catheter sites
Prophylaxis:
1. handwashing
2. meticulous oral hygiene
3. prophylactic anti-fungal/viral drug
4. protective isolation
Treatment:
1. prompt initiation of Abx therapy in febrile neutropenic pts
2. identifying the invasive organism
3. treating the accompanying infection with appropriate Abx
Manifested by FEVER AND SHAKES (RIGORS)
To resolve: WHITE CELL RECOVERY is critical
Abx related side effects:
1. skin rash
2. nausea
3. liver/kidney dysfunction
4. diarrhea (eg. Abx induced overgrowth of C.diff)
Abx effectiveness in BMT
- reduction of fever
- subjective improvement in other signs of infection with 2-3 days (pt states they feel well)
- blood cultures remain or become NEGATIVE
Abx related side effects:
- skin rash
- nausea
- liver/kidney dysfunction
- diarrhea (eg. Abx induced overgrowth of C.diff)
Aspergillus
- a fungus that usually affects the lungs or sinuses
- most common life-threatening infection in BMT pts
- some pts already have this organism in body at the time of hospitalization
HEPA filtration is utilized to filter it out
Problems associated with use of Abx
- immunocompromised pts that at an increased risk for infection may respond POORLY to Abx
- bacteria develops resistance to Abx
- Abx toxicities
- specific damage produced by Abx
- Abx induces allergic response
S&S of allergic reactions
- maculopapular rash (red bumps on a flat, red patch of skin)
- urticaria (hives)
- pruritus
- difficulty breathing
Interventions when allergic reactions occur
- stop the drug immediately
- administer Epinephrine, antihistamines, corticosteroids
- may require assisted ventilation
Interventions when diarrhea occurs
- collect a sample for C.diff toxin assay
- notify Dr.
**at VGH, lab will not run a specimen if c.diff is done WITHIN the last 7 days.
