This randomized controlled study with a comparative experimental design investigated the effects of using lidocaine spray with regard to the pain and anxiety of patients administered a contrast medium during venipuncture. Data were collected from 55 patients who visited the Department of Radiology at N General Hospital, Seoul, for undergoing computed tomography or magnetic resonance imaging, met the subject-selection criteria, and provided consent for participating in the study during February and March 2015. The visual analog scale (VAS) was used to measure subjective pain, and the objective pain behavior checklist developed by Park was used to measure objective pain. Subjective anxiety was measured using the VAS, and the anxiety state was measured using the anxiety scale revised and supplemented by Leek. The study found that the experimental group sprayed with lidocaine during venipuncture scored significantly lower points for subjective pain (t = -2.86, p = .006), objective pain (t = -3.82, p < .001), subjective anxiety (F = 4.36, p = .042), and anxiety state (F = 5.02, p = .028) than did the control group. These findings indicate that lidocaine spraying influences pain reduction.
