The effect of duration of pressure on bruising and pain in the subcutaneous heparin injection site.

It was concluded in this study that the duration of pressure applied to the injection site after subcutaneous LMWH injection did not affect the size of bruising or the severity of pain, and, unlike in the literature, that 60 s of applied pressure did not have a positive effect. Also, it was found that gender had an effect on the formation of bruising and the severity of pain, and body mass index had an effect on pain severity. Ten seconds of pressure applied to the injection site after subcutaneous LMWH injection may be enough to reduce complications.
