Skin and Soft Tissue Infections Flashcards
What are some conditions that are purulent SSTI?
Bullous impetigo, carbuncles, abscess, folliculitis, purulent cellulitis
What are some conditions that are non-purulent?
Non-bullous impetigo, non-purulent cellulitis
What are the most common symptoms of typical Cellulitis?
hot
pain
redness
swelling
fever, chills malaise
perhaps pus
What microorganisms cause SSTI’s and do they generally purulent or non-purulent?
GAS- Non-purulent
Staph aeurus= purulent
What are the Risk factors for MRSA?
crowded, contact, compromised skin, contaminated, lack of cleanliness
under the age of two or greater than 65
Gay
Athletes
antibiotic use recently (6 months)
trauma
surgery/ IV use
When should we decide to cover for MRSA?
if endemic
if at risk
if immunocompromised or seriously ill
What are the go-to agents for non-purulent cellulitis?
1st= Cephalexin 500mg QID (100mg/kg/day QID for child)
If penicillin allergy= Clindamycin 300mg QID or erythromycin 250mg QID
What are the go-to agents for purulent cellulitis?
1st= cephalexin 500mg QID, Cloxacillin 500mg QID
if MRSA or Penicillin allergy= TMP/SMX 1-2 DS tab BID or Doxycycline 100mg BID
ALT= clindamycin- resistance is an issue, Ciprofloxacin- resistance is an issue
If we wanted to cover for both GAS and MRSA what agents would we use?
Cephalexin AND TMP/SMX or Doxy
Clindamycin covers both but resistance is high
True or False: The duration of therapy for SSTI’s 7 days
FALSE
for uncomplicated 5 days is sufficient
True or Flase: SSTI’s often worsen after starting antibitotics
TRUE
When can the patient expect full healing (including inflammation and symptoms)?
1-2 weeks after antibiotics are stopped
What are some methods of non-drug treatment for SSTI’s?
Incision and drainage= KEY for purulent
Elevate limb= can be essential as well
True or False: Drainage of Cellulitis is essential for treatment
FLASE Only helps for purulent cellulitis
