Background and Objective: Injection of subcutaneous low molecular weight heparin often causes some local reactions such as ­bruising, hematoma­, and pain, directly related to inappropriate injection method­. This study aimed at determining the effect of injection duration of­ Subcutaneous Enoxaparin Sodium on the size of bruising and the severity of injection pain.   Material and Methods: This experimental study was conducted on ۳۶ patients medicated by subcutaneous Enoxaparin Sodium (۶۰mg). ­­They were randomly divided into two groups.­ The first group received routine method of subcutaneous anoxaparine injection (۱۰ second duration injection technique) and in the second group in addition to routine method, ­“۱۰ second waits” before removing needle was performed. Data collection was carried out by using a researcher-made check-list consisting of a section for demographic data and a section to record the extent o f bruising and pain intensity.­ The Extent of bruising was measured by using a clear flexible ruler within ۲۴, ­ ۴۸ and ۷۲ hours and pain intensity by visual analog scale (VAS) ,immediately after injection­.­­We analyzed the Data by independent T test and Chi square.   Results: ­ The ­Results indicate ­­that­ the mean ­of pain intensity in second group (­۳.۰۵ ± ۱.۷۱­)­ is less than first group (­۳.۸۶ ± ۲.۷۵­)­.­There is no significant difference between two groups for the extent of bruising in ۲۴, ­ ۴۸ and ۷۲ hours (P>۰.۰۵).   Conclusion: with regard to ­pain intensity and the size­ of the bruising, the two groups are not significantly different.
