The Effect of Vibration on Pain During Subcutaneous Heparin Injection

Aim: The aim of this research was to examine the effect of the local vibration technique applied to the injection site during subcutaneous low molecular weight heparin (LMWH) injection. Methods: The patients were randomly assigned to an experimental (vibration) group (n= 32), a placebo control group (n= 30), and a nonintervention control group (n= 31). Participants in the experimental group were given slight vibration to the injection site before the injection was administered; for participants in the placebo group, the device was placed on the injection site but with the vibration button kept switched off, while for the nonintervention control group, routine subcutaneous low molecular weight heparin injection was administered. The level of pain felt by the participants during the administration of the injection was assessed with a visual analog scale.
