Abstract
Aim of the study: To investigate the effect of support surface usage and positions on interface pressure during surgery. Materials and methods: This randomized controlled experimental study was conducted between October 2018 and June 2019. The study included patients who had planned surgery in supine and prone positions. The sample size was 72 patients. Patients were assigned to three groups (gel support surface, viscoelastic support surface and standard operating table) according to the determined randomization table. During the surgery, the pressure in the patients' body was recorded. The statistics program IBM SPSS Statistics 25.0 packaged software was used in the analyses of data. Results: There was no statistically significant difference between the total body average interface pressure (mmHg) values between the supporting surfaces in the prone position. There was a statistically significant difference between the total body average interface pressure (mmHg) values between the support surfaces in the supine position, and the average interface pressure measured on the viscoelastic foam support surface was significantly lower than the gel support surface and the standard operating table. Conclusion: In the study, the use of viscoelastic foam support surface was found to be more effective than the use of a standard operating table and gel support surface. Viscoelastic foam support surface is recommended for patients at risk for pressure injury in the operating room. © 2021 Tissue Viability Society
