Objectives: to map the Nursing prescriptions for patients with diagnoses related to hypothermia in the intraoperative period with the activities proposed by the Nursing Interventions Classification, and to characterize the sample based on the risk factors for the development of this discomfort. Method: a descriptive, documentary and retrospective study, with a quantitative approach that followed three stages: cataloging of the interventions, documentary analysis, and cross-mapping. The following variables were analyzed: patient's age and gender; surgery duration; minimum, mean and maximum temperatures, and variation of the surgery room and patient temperatures; and whether or not the type of surgery involved opening a body cavity, in a sample of 138 medical charts evaluated from August to September 2019 by using a checklist composed of identification data and diagnosis components from the NANDA-International diagnoses: risk of perioperative hypothermia and hypothermia. Absolute and percentage frequency analyses, mean, standard deviation, and the R software were employed. Results: 419 activities incorporated in 12 interventions were verified that were related to hypothermia in the corresponding taxonomy; as well as 13 Nursing care measures prescribed and five interventions mapped. The variables which reached significance were surgery duration and cavity opening. Conclusion: by means of cross-mapping, it can be asserted that the care measures prescribed are based on the standardized language, thus contributing to unification of the Nursing practice.
