The effect of subcutaneous injection angle on pains

Objective To investigate the effect of subcutaneous injection angle on pains and improve compliance of injection. Methods A total of 80 diabetic patients initially receiving insulin injection were randomly divided into intervention group and control group, 40 subjects in each group. The subjects were assigned to conventional angle (30°～40°) injection and 90 degrees injecion respectively , so as to compare the effects of inject angle on pains, site callosity, first injection success rate, compliance and episodes of hypogly-cemia. Results A significant difference was observed between two groups in respect of injection pains (P 0.05) . Conclusions Changing the injection angle to 90 degrees can relieve patients' injection pains and improve compliance of injection without decreasing treatment effects. Key words: Subcutaneous injection angle;  Site callosity;  First injection success rate;  Compliance;  Pain
