Purpose: to determine the effectiveness of using patterned spalk on the level of anxiety in children who have an IV in the children's ward at RSUD Muntilan. The method used in this study was a quasi-experimental study using 2 groups of pres test and post test with a control group and an intervention group. Respondents in this study were 52 child respondents in the children's ward at RSUD Muntilan, by using purposive sampling technique. The measuring instrument used to measure the level of anxiety of children aged 1 to 6 years uses the SCAS (Spance Children's Anxiety Scale) and the observation sheet. Result: there is a significant effect on the level of anxiety of the child who is given. The act of using spalk is patterned in the intervention group with p value = 0.000 (p <0.05). There was a positive effect on the children who were attached with patterned spalks, the children looked happy and the anxiety decreased compared to the children who only wore plain spalk wrapped in gauze. So that the use of patterned spalk on children who have the IV line is proven to be effective in reducing anxiety levels.
