BACKGROUND: Intramuscular (IM) injection is one of the causes of anxiety and pain in patients,
using new techniques and creating a pleasant experience is of the legal and ethical duties of nurses.
We aimed to investigate comparison of skin traction, pressure, and rapid muscle release with
conventional method on IM injection pain.
MATERIALS AND METHODS: This clinical trial investigated 28 patients (56 samples) who required
Methocarbamol injection. Two 5 cc Methocarbamol were injected for each patient by the conventional
and innovative methods. In the innovative technique, after applying skin traction and imposing deep
pressure to the muscle, the needle was inserted at a 90° in the muscle and injected after aspiration.
However, this deep pressure was not applied in the conventional method. The pain was measured
using visual analog scale. STATA software version 12 was used for statically analysis. P < 0.05 was
considered statistically significant.
RESULTS: The findings showed pain intensity in innovative method and conventional method was
1.17 ± 0.75 and 2.78 ± 1.61, respectively. The difference was statistically significant (P = 0.001). The
minimum pain intensity in innovative method was 0 and maximum was 4, meanwhile in conventional
injection, the lowest and highest pain intensity was 0 and 6 respectively.
CONCLUSION: The results of this study showed that innovative method can be used as a substitute
for conventional method to reduce IM injection pain.
