Effects of subcutaneous injection after coolant spray on pain, hematoma,
and ecchymosis in three different regions
Abstract
Aims: This study determined the effect of subcutaneous (SC) low
molecular weight heparin (LMWH) injection in three different areas
(abdomen, leg, and upper arm) after coolant spray application on pain,
hematoma, and ecchymosis formation. Methods: The sample of this
randomized controlled study consisted of 50 patients that were
administered SC LMWH once a day. The SC injection occurred after
applying coolant spray to the arm, leg, or abdominal region. The sample
of this randomized controlled study consisted of 50 patients that were
administered SC LMWH once a day. The SC injection occurred after
applying coolant spray to the arm, leg, or abdominal region. Results:
The study determined that there was no statistically significant
difference in pain severity, hematoma, and ecchymoses between the
regions of SC injection after coolant spray was applied
(p>0.05). However, the highest average pain intensity
directly and 15 minutes after the SC injection was in the leg region.
Conclusion: SC injection after coolant spray application in three
different regions led to the biggest hematoma in the abdominal region,
the biggest ecchymosis in the arm region, and the lowest pain severity
in the abdominal and arm regions. Key words: Coolant spray, ecchymosis,
hematoma, pain, subcutaneous injection (SC).
