Objective: to describe nursing care in peripheral intravenous catheterization in hospitalized children. Method: integrative review carried out in November 2020 in LILACS, CINAHL, MEDLINE, SciELO, BDENF and COCHRANE databases. The analysis was constructed from the processes of this review. Results: 19 articles were analyzed, classified according to the level of evidence: level II (5%), level IV (21%), level V (5%), level VI (63%) and level VII (5%). Analytical category "Care for hospitalized child requiring peripheral intravenous catheter". Ultrasound was considered a useful technology. The most used and recommended catheter is the 24 Gauge caliber and the ideal dressing is to use sterile transparent film. Venipuncture in children is more difficult than adults and is often associated with adverse events. Elective catheter replacement is not recommended in children, but there are still doubts. The Difficult Intravenous Access score determines the probability of catheterization failure. Specialized and trained nursing professionals make a difference in this procedure. One should be concerned with pain, using pharmacological and non-pharmacological devices to minimize it. Conclusion: this review contributes to good practices in the care of peripheral intravenous catheterization in children and was based on data on the main technologies used, forms of prevention of adverse events, as well as nursing actions that ensure the safest and least stressful process for children and their families.
