Objective: To correlate the support surfaces used in the surgical positioning with the occurrence of pressure injuries resulting from this practice.
Method: exploratory, descriptive, retrospective study of correlation with patients of a large, private philanthropic hospital in São Paulo - Brazil. We evaluated 145 patients from a database of a previous study on positioning lesions. Inclusion criteria were elective adult surgical patients admitted to the preoperative and day clinic from 6 to 7 pm, who spontaneously agreed to participate in the study. Were excluded pediatric patients, adults from other hospitalization units, and who did not use a support surface for surgical positioning. The previous project was approved by CEPIEPHSL 1.935.424, with the objective of evaluating the occurrence of skin lesions due to the surgical positioning, the patients were approached in the preoperative period, the skin evaluation was performed, were collected the antecedents, type of positioning and surfaces used, and a new evaluation of the skin in the postoperative period. Data were analyzed using Pearson's statistical correlation test.
Results: the procedures were small, medium and large, different specialties and the support surfaces used were viscoelastic, pyramidal foam, adhesive dressing, vacuum mattress, cotton cloth field and pillow, in some procedures there was a combination of more a surface. The occurrence of lesions by positioning was observed in five patients. The correlation tests were significant for viscoelastic (p 0.003), pyramidal foam (p 0.024), adhesive dressing (p 0.055) and pillow (p 0.003).
Conclusion: the low incidence of lesions by positioning in this sample shows the importance of the use of support surfaces as a prevention method, the significant values of the correlation reinforce the potentiality of these surfaces in the prevention of pressure lesions in the surgical positioning.
