I.
The management of burn wounds continues to rely
largely on daily surveillance by routine clinical examination.
Care plans may vary depending on the appearance of the
burn wound, skin graft, or donor site.
II.
The burn dressing is central to burn wound care and
serves three functions:
A.
protection of the thermally injured skin from
bacterial colonization by wound isolation
B.
minimizing metabolic disturbances by reducing
evaporative heat loss and reducing shivering
C.
providing comfort by eliminating surface air
currents from the wound and by absorbing wound secretions.
III.
Tub daily
Tubbing facilitates the removal
of debris and exudate that accumulates between dressing
changes. Patients receiving dressing changes should, if
possible, be brought at least once daily to the burn tub to
have wounds cleansed. The
frequency of tubbing can be increased if wounds have
especially profuse drainage.
IV.
Topical Agents
A.
Systemic antibiotics are rarely able to reach areas
of avascular eschar. Topically applied antimicrobials provide
high concentrations of antibiotic on the wound surface, where
microbial numbers are the highest. Topical antimicrobial therapy delays and minimizes wound
microbial colonization[i]
and the subsequent risk of invasive burn infection.
However, none of the topical antimicrobials will
totally eliminate the colonization of major burns.
Only in conjunction with close clinical monitoring and
debridements will topical antimicrobials provide the best
defense against the septic burn wound.
B.
Initially there are few bacteria on the surface of
the burn wound and usually consist of normal cutaneous flora
such as Staphylococcus
epidermidis, some diptheroids, and perhaps Staphylococcus aureus. After
several days, S. aureus numbers
begin to increase and typically will predominate. Gram-negative species can also appear, and usually are from
the Pseudomonas,
Proteus, Klebsiella, and coliform species.[ii],[iii],[iv]
Clostridium are seen in high-voltage electrical
injuries.

ssd
bid to___________________
C.
Silver sulfadiazine (a.k.a. Silvadeneâ,
Thermazeneâ,
and SSDâ)
is the most commonly used prophylactic topical antimicrobial
in burn patients. SSD
is an insoluble, white cream, available in a 1% concentration
and is applied twice daily.
SSD has the advantages of being relatively painless to
apply, and its activity against a wide variety of organisms,
including S. aureus, E.
coli, Klebsiella, Pseudomonas aeruginosa, Proteus, the
Enterobacteriaceae, and Candida
albicans.
D.
The
disadvantages of SSD are its poor penetration of eschar, and a
transient leukopenia which occurs 2 to 3 days after therapy is
initiated. This
leukopenia occurs in between 5 and 15% of patients, resolves
whether or not the agent is withdrawn, and is not associated
with any infectious complications.
Often a yellow-gray film, termed
“pseudo-eschar,” may form as a result of
interaction between SSD and the wound exudates that can mask
true burn depth diagnosis.
IV.
sulfamyalon
cream bid to____________
A.
Mafenide (a-amino-p-toluene
sulfonamide monoacetate) or Sulfamylonâ,
is a water-soluble cream.
It has excellent antibacterial activity against most
gram-positive (including clostridia) and gram-negative
species. However,
it has limited activity against some staphylococci, especially
methicillin-resistant strains, and limited antifungal
activity.1 Sulfamylon
has excellent eschar penetration. It is applied twice daily.
B.
Sulfamylon is a potent carbonic anhydrase
inhibitor, and hyperchloremic metabolic acidosis is frequent
when it is used on large burns.[v]
Respiratory compensation for the acidosis is typical
and is manifest by hyperventilation and low PaCO2.
The risk of systemic toxicity increase as the area
treated increases.
IV.
bacitracin
to_____________________
Bacitracin
, Neosporin, and Polysporin are petroleum and mineral
oil-based topical antimicrobial ointments.
They are bactericidal for a variety of gram-positive
and gram-negative bacteria, but have limited ability to
penetrate eschar. These
ointments are applied to partial-thickness burn wounds.
V.
xeroform
daily to______________
Xeroform
is a fine mesh gauze dressing containing bismuth, and is
designed to be an inexpensive, nonadherent covering with some
antimicrobial properties.
On partial-thickness wounds and skin grafts, xeroform
is applied once daily and covered with gauze.
For skin graft donor sites it is applied once and left
to air dry in place.
VI.
other__________
A.
Acticoat is an antimicrobial silver-coated barrier
wound dressing. In
a study comparing Acticoat to silver nitrate, silver
sulfadiazine, and mafenide acetate, Acticoat had the lowest
minimum inhibitory and bactericidal concentrations, and
generated similar zones of inhibition to silver nitrate and
silver sulfadiazine. Viable bacteria were undetectable 30
minutes after inoculation with the dressing, whereas it took 2
to 4 hours for silver nitrate and silver sulfadiazine to
achieve the same result.[vi]
B.
The
dressing is applied to a clean, partial-thickness burn and is
covered with gauze. The dressing is then moistened with sterile water once daily
for three days, after which time the patient returns to have
new Acticoat placed, which remains in place until the next
follow-up appointment.
