Intralesional injection of triamcinolone acetonide (TA) which is widely
used for the treatment of keloid, is painful and as a result many
patients discontinue the treatment. We evaluated the effect of
pretreatment with topical 60% lidocaine tape on pain and tolerability of
intralesional TA treatment in keloid patients. We studied 20 patients
with keloid who had previous experience with intralesional injection of
TA and intolerable pain leading to discontinuation of treatment. All
patients were pretreated with 60% lidocaine tape that was placed on the
keloids for more than 120min before intralesional injection of TA. The
patients’ assessment of pain was based on a 100-mm visual analog scale
(VAS) anchored at 0 for ‘‘no pain’’ and 100 for ‘‘worst possible pain.”
Pain assessment was performed immediately after the TA injection using
VAS score. Finally, the patients’ tolerability towards this treatment
was assessed. The Mean VAS score in the control patients who received
intralesional injection of TA without lidocaine pretreatment was
82.6±14.4mm. On the other hand, the VAS score of the patients with
lidocaine pretreatment was 18.9±11.3mm, which was significantly lower
than that of the control group. Thus, the pain during intralesional
injection of TA for treatment of keloids was relieved by pretreatment
with lidocaine tape and patients could tolerate this therapy. |
