LidocaineHydrochloride ۲% solution was sprayed on the margin and center of the wounds in both groups. The painscores were measured by the VAS instrument and anxiety levels by the RASS questionnaire. Blood pressureand heart rate were measured during the first hour after the intervention at minutes ۰-۳-۱۰, and then, by ۱۰-minute intervals.Results: The mean pain score, systolic blood pressure, and heart rate ۱۰ to ۶۰ minutes after the interventionwere significantly lower in the test group than in the control group. However, the mean diastolic blood pressurewithin one hour, as well as the mean heart rate and anxiety in the two groups, did not differ significantly untilthe tenth minute after the intervention.
