Background:
Routinely kirshner wires are left above skin level to facilitate re-
moval once the fracture is sufficiently healed. In children wire removal may be
associated with pain and discomfort. The procedure is frequently done in the
outpatient clinic without any anesthesia or analgesia.
Purpose / Aim of Study:
Prior to implementing topical analgesia as a standard
procedure, we wanted to evaluate potential benefits of topical analgesia on pain
associated with wire removal. We conducted a study comparing the intensity of
pain with or without topical analgesia.
Materials and Methods:
The study was conducted as a prospective study with
81 patients included in two consecutive groups. Mean was age 8.5 years (range
4-14). The first 40 patients were allocated to wire removal without analgesia.
The following 41 patients underwent removal after topical application of Emla
(lidocaine, prilocaine) around the wires one hour prior to the procedure. Pain
scores were recorded prior to wire removal/application of Emla and after wire
removal using FPS-R (4-12 years) and a numerical scale (1-10) (12-17 years)
indicating baseline pain and the maximum level of pain. Data were normally dis-
tributed and evaluated using student’s t-test.
Findings / Results:
We found no statistically significant effect of topical anal-
gesia vs. no topical analgesia. Both groups had similar baseline scores; mean 1.1
vs. 1.2 (p=0.78). Increase in the level of pain was 3.7 vs. 2.9 (p=0.28).
Conclusions:
Based on this study, topical analgesia does not provide any posi-
tive effect on pain related to wire removal. Besides the expenses related to ac-
quisition, application of Emla prolongs the stay in the outpatient clinic for these
young patients and may also cause local side effects. Therefore, topical analge-
sia with Emla is not warranted as a standard procedure for children undergoing
wire removal.
