Abstract Background and Objective: The purpose of the study was to assess the incidence of superficial thrombophlebitis among Pediatric patients and to identify the determinants associated with the development of superficial thrombophlebitis among pediatric patients. Material and Methods: The research design used in this study was a descriptive cross – sectional study. Population of the study comprised of all the children who are on intravenous therapy. Four hundred samples were selected by convenient sampling. Data collection proforma included subjective data sheet, visual infusion phlebitis (VIP) scale and questionnaire to determine the determinants of superficial thrombophlebitis. Results: The incidence of thromboplebitis was 80 .75 %. There was a significant association (p<0.05) between the incidence of thromboplebitis and site of cannulation, cannula size and cannulation duration. Conclusion: It was detected that the incidence of superficial thrombophlebitis was higher among hospitalised children receiving intravenous therapy in pediatric ward. Nurses need to be trained in skills required for cannulation. Early identification and prompt treatments are required to reduce the complications related to peripheral intravenous cannulation.
