Bruising is an unpleasant result of subcutaneous injection of Enoxaparin, which causes physical discomfort,
limitation of injection site, patient's refusal of treatment, and distrust in nurses’ ability. The application of
techniques which reduce patients’ fear, anxiety, and physical damage is one of the tasks of nurses. This
clinical trial investigated the effect of duration of subcutaneous Enoxaparin injection on the bruising size in
acute coronary syndrome patients
Seventy 3575yearold acute coronary syndrome patients hospitalized in Coronary Care Units were selected
randomly. Each subject received 10 and 30sec duration of injections by a single researcher on both sides of
the abdomen in 12h intervals. The bruising size was measured using a transparent millimeter measuring
paper, 24 and 48 h after each injection. Data were gathered by a data recording form (demographic and
measurements data) and analyzed by descriptive statistics and nonparametric tests through SPSS.
