splenectomy Flashcards
what percent of cardiac ouput filters through the spleen?
25%
tears of the ……… can result in massive hemmorrhage or tear of the splenic capsule
short gastric arteries
these vessel may be ligated with no impact on organ viability
short gastric arteries
this ligament poses a risk of tearing the splenic capsule during gastric surgeries
splenocolic ligament
structures surrounding the spleen
stomach
diaphragm
splenic flexure of colon
part of the spleen can be resected due to its
segmental internal vasculature
the spleen produces …….. that aids in opsonization
IgG, IgM
the spleen is vital to preventing infections from
encapsulated bacteria
splenomegaly implies
advanced/late stage disease
the spleen must be quite large to be palpable
the spleen produces …….. which accelerates opsonization
tuftsin
major pathogens that pose risk to asplenic patients
Hib
N. meningitides
S. pneumo
vaccination should be given…….prior to planned splenectomy
2 weeks
asplenic patients should receive vaccinations every….
5 years
asplenic patients should carry an Rx for
prophylactic antibiotics to be taken at symptom onset
most critical for preventing OPSI in asplenic patients
patient education
function of the spleen
filters blood
removes senescent RBCs
asplenic patients are
immunologically impaired
do not clear bacteria well
more susceptible to DVT
organisms not associated with OPSI
E. coli
S. aureus
85% of splenic trauma bleeding
w
will self resolve
if patient is hemodynamically unstable,
proceed to splenectomy
indications for splenectomy
multiple organs injured
in shock
acidotic
splenic embolization is an option if
the patient is stable
if the patient is already in a conventional OR for massive hemorrhage
embolization is not primary option
if possible, avoid splenectomy prior to …. years of age
