Local anaesthesia should be used with caution, as
the application of anaesthetics (ointments, creams)
may be insufficient and infiltrate local anaesthesia.
In particular, vasoconstrictive agents (epinephrine)
may lead to suppression of local immune protection
and thus enhance bacterial load and infection.
Benefits
The primary benefit of sharp and surgical
debridement is the speed of removal of dead
tissue. These procedures allow fast and effective
removal, allowing the healing process to start
immediately. A further benefit of sharp excision
is the low cost of treatment compared with, for
example, surgical debridement.
Among the benefits of surgical debridement is that
it is possible to remove dead tissue when other
alternative methods are ineffective. This method is
quick and essential when the presence of devitalised
tissue becomes life threatening for the patient.
Another benefit is the possibility to close the wound
when immediate reconstruction is performed.
There is some documentation available on the
benefits of surgical debridement with regard to
increased healing rates, improved status of the
wound and a reduction in pain related to the
wound status after the procedure.

Contraindications
Surgical and sharp debridement are non-selective
methods, bringing the risk of over-excision into
consideration.

Over-excised wounds might heal
with scarring, lead to a significant delay in healing
(when debridement is brutal/not gentle), or cause
damage to the deeper structures may occur. However,
this is rarely the case for sharp debridement, as this
method is usually performed with the intention to
remove small amounts of visible non-viable tissue.
Considerations and precautions should be taken
in specific areas, such as temporal areas, neck,
axilla, groin and other areas where neurovascular
bundles pass superficially and damage to the vitally
and functionally important structures (major
blood vessels, nerves and tendons) may occur. In
these situations, whenever removal of necrotic
tissue is indicated, surgical debridement must be
performed by an experienced specialist. Usually
these procedures take place in a dedicated facility
(operating theatre or procedural room) and with
use of appropriate anaesthesia.
Although the risk is small, a potential enlargement
of the wound in the deeper layers must be
considered and pre-procedural planning and
proper evaluation must be performed. Pocketing of
the wound, involving the deep structures (blood
vessels, nerves, tendons or even bones), may
require an major procedure, involving removal and
replacement of the affected structures.
As sharp and surgical debridement may be very
invasive procedures, special precautions must be
taken into account when treating functionally
and cosmetically important areas, such as the face,
hands, perineum and feet. Excessive damage of the
tissue should be avoided and alternative techniques
should be considered for treatment of these areas.
Contraindications for sharp and surgical
debridement are few. The most important are
a poor general state of the patient and the
disturbance of the blood coagulation. Usually
these contraindications are relative, as sharp
debridement is a small intervention that drastically
improves the patient state in the majority of
cases, leading to the release of cytokines and
mediators of the inflammation. Debridement will,
in all cases, improve the wound healing if over-
debridement is avoided.
However, an absolute contraindication for any
sharp debridement is refusal from the patient and
choice of alternative treatment method should be
