There can be variation in the licensing of
different medicines containing the same drug.

1.3 Peri-operative analgesia
Peri-operative analgesia
Non-opioid analgesics
Since non-steroidal anti-inflammatory drugs (NSAIDs) do
not depress respiration, do not impair gastro-intestinal
motility, and do not cause dependence, they may be useful
alternatives or adjuncts to opioids for the relief of
postoperative pain. NSAIDs may be inadequate for the relief
of severe pain. Diclofenac sodium p. 1198, diclofenac
potassium p. 1197, flurbiprofen p. 1203, ibuprofen p. 1203,
ketoprofen p. 1207, paracetamol p. 465, parecoxib p. 1413,
and ketorolac trometamol p. 1412 are licensed for
postoperative use. Diclofenac and paracetamol can be given
by injection as well as by mouth. Diclofenac sodium can be
given by intravenous infusion for the treatment or
prevention of postoperative pain. Intramuscular injections
of diclofenac sodium and ketoprofen are rarely used; they
are given deep into the gluteal muscle to minimise pain and
tissue damage. Ketorolac trometamol is less irritant on
intramuscular injection but pain has been reported; it can
also be given by intravenous injection.
Suppositories of diclofenac sodium and ketoprofen may be
effective alternatives to the parenteral use of these drugs.
Opioid analgesics
Opioid analgesics are now rarely used as premedicants; they
are more likely to be administered at induction. Pre-
operative use of opioid analgesics is generally limited to
those patients who require control of existing pain. See
general notes on opioid analgesics and their use in
postoperative pain.
See the management of opioid-induced respiratory
depression in Pre-medication and peri-operative drugs
p. 1403.
Intra-operative analgesia
Opioid analgesics given in small doses before or with
induction reduce the dose requirement of some drugs used
during anaesthesia.
Alfentanil p. 1413, fentanyl p. 479, and remifentanil
p. 1414 are particularly useful because they act within
1–2 minutes and have short durations of action. The initial
doses of alfentanil or fentanyl are followed either by
successive intravenous injections or by an intravenous
infusion; prolonged infusions increase the duration of effect.
Repeated intra-operative doses of alfentanil or fentanyl
should be given with care since the resulting respiratory
depression can persist postoperatively and occasionally it
may become apparent for the first time postoperatively when
monitoring of the patient might be less intensive. Alfentanil,
fentanyl, and remifentanil can cause muscle rigidity,
particularly of the chest wall or jaw; this can be managed by
the use of neuromuscular blocking drugs.
In contrast to other opioids which are metabolised in the
liver, remifentanil undergoes rapid metabolism by
nonspecific blood and tissue esterases; its short duration of
action allows prolonged administration at high dosage,
without accumulation, and with little risk of residual
postoperative respiratory depression. Remifentanil should
not be given by intravenous injection intraoperatively, but it
is well suited to continuous infusion; a supplementary
analgesic is given before stopping the infusion of
remifentanil.
