Antidepressants


There
was
no
significant
difference
in
pain
or
disability
in
SCI
patients
with
chronic
pain

treated
with
amitriptyline
or
placebo
(Cardenas
et
al,
2002
Level
II);
however
amitriptyline

improved
below‐level
neuropathic
pain
in
patients
with
depression
(Rintala
et
al,
2007
Level
II).

There
are
no
studies
of
selective
serotonin
reuptake
inhibitors
(SSRIs)
in
the
treatment
of

central
pain
(Finnerup,
Otto
et
al,
2005
Level
I).

Anticonvulsants

Pregabalin
significantly
reduced
central
pain
and
improved
sleep,
anxiety
and
global

impression
of
change
in
patients
with
SCI,
compared
with
placebo
(Siddall
et
al,
2006
Level
II).

Smaller
trials
supported
the
effectiveness
of
gabapentin
in
decreasing
central
pain
and

improving
quality
of
life
(Levendoglu
et
al,
2004
Level
II;
Tai
et
al,
2002
Level
II).
Lamotrigine

reduced
spontaneous
and
evoked
pain
in
patients
with
incomplete
SCI
(Finnerup
et
al,
2002

Level
II).
Valproate
was
ineffective
in
the
treatment
of
SCI
pain
(Drewes
et
al,
1994
Level
II).


Intravenous
anaesthetics


An
IV
bolus
of
low‐dose
propofol
reduced
the
intensity
of
central
pain
and
allodynia
for
up

to
1
hour
in
approximately
50%
of
patients
(Canavero
&
Bonicalzi,
2004
Level
II).

Non‐pharmacological
techniques

Self‐hypnosis
as
well
as
electromyelograph
(EMG)
biofeedback
training
led
to
reduced
pain

intensity
in
patients
with
SCI;
in
some
aspects
self‐hypnosis
was
superior
to
EMG
biofeedback

(Jensen
et
al,
2009
Level
II).

Treatment of nociceptive and visceral pain after spinal cord injury
There
is
no
specific
evidence
to
guide
the
treatment
of
acute
nociceptive
and
visceral
pain

in
SCI
patients.
Treatment
must
therefore
be
based
on
evidence
from
other
studies
of

nociceptive
and
visceral
pain.


Key
messages

1.
 Gabapentinoids
(gabapentin/pregabalin)
(S),
intravenous
opioids,
ketamine
or
lignocaine

(lidocaine)
(U)
tramadol,
self‐hypnosis
and
electromyelograph
biofeedback
(N)
are

effective
in
the
treatment
of
neuropathic
pain
following
spinal
cord
injury
(Level

9.3 ACUTE BURN INJURY PAIN


Acute
pain
following
burn
injury
can
be
nociceptive
and/or
neuropathic
in
nature
and
may
be

constant
(background
pain),
intermittent
or
procedure‐related.
There
is
limited
evidence
for

the
management
of
pain
in
burn
injury
and
treatment
is
largely
based
on
evidence
from
case

reports
and
case
series,
or
data
extrapolated
from
other
relevant
areas
of
pain
medicine.


Burn
pain
is
often
undertreated,
particularly
in
the
elderly
(Choiniere,
2001).
However,
effective

pain
management
after
acute
burn
injury
is
essential,
not
only
for
humanitarian
and

psychological
reasons,
but
also
to
facilitate
procedures
such
as
dressing
changes
and
