Abstract
Introduction
Coolant spray application in musculoskeletal injuries is an effective and harmless
method to treat pain and reduce functional limitation. This study assessed the clinical
value of coolant spray application on patient comfort before and during the radiographic
imaging process along with its early analgesic and anti-edema effects.
Methods
A total of 155 patients, admitted to the emergency department between April 1, 2019,
and June 31, 2019, were included in this study. The patients were randomly assigned
to either a coolant spray or a saline spray (placebo) group. To the coolant spray
group patients, Cryos ®Spray (Phyto Performance, Italy) was applied. To the placebo
group patients, a normal saline solution in a bottle covered with white opaque paper
and refrigerated at 4 °C was sprayed. Radiographic images of the patients were scored
for appropriateness of the standard imaging characteristics.
Results
The mean scores were 8.13 ± 1.8 and 6.58 ± 2.2 for the coolant spray and normal saline
spray groups, respectively; the differences were statistically significant between
the two groups (mean difference: -1.56, 95% CI:-2.20 to −0.92; p = .000). Patients with fractures on their radiographs and treated with coolant spray
received higher scores than similar patients treated with normal saline spray (mean
difference:-1.92, 95% CI:-3.28 to −0.55; p = .009). The proportion of patients requesting analgesic treatment before discharge
was statistically lower in the coolant spray group compared to the normal saline group
(p = .025).
Conclusions
The radiographic images taken after coolant spray intervention in patients with acute
ankle trauma were more successful in showing the target structures.
