Abstract: Objectives: To find out the effect of “animated cartoon” on behavioral response to pain perception among children undergoing surgery. Methods: A quantitative research approach with a quasi-experimental design was used to conduct the current study. 60 numbers of samples were selected by purposive sampling technique (30 in each interventional and control group) ages 3-6 years of children undergoing surgical dressing, admitted in the surgical unit of IMS and SUM Hospital, Bhubaneswar. During the surgical dressing “Animated cartoon” video was played and shown to the experimental group. The behavioral response to pain perception was measured by the “FLACC” behavioral pain assessment tool. Result: As per the statistical analysis in the experimental group 46.6% of the samples were having a moderate level of pain whereas in the control group 53.3% of samples were having moderate pain. The mean and standard deviation of the score of behavioral response to pain perception in the interventional and control group were 2.83 ±1.36 and 1.7 ± 1.9 at p>0.0001 respectively. The inferential statistics t-test analysis showed that animated video cartoons can be an effective diversion method for reducing pain. Conclusion: Animated cartoon video is an effective method of pain reduction among children undergoing surgery.
