Abstract: Aims and objectives. In this experimental study, a 4‐cm thermoactive viscoelastic foam overlay and a heating source on the operating room table was compared with the standard operating room table with a heating source for the effect on the postoperative pressure ulcer incidence in cardiac surgery patients. Background. Pressure ulcer incidence in the cardiac surgery population is reported to be up to 29·5%. The prolonged compressive forces from lying on the operating room table are one source of pressure ulcer development in this population. Pressure‐reducing devices on the operating room (OR)‐table should reduce the patients’ interface pressure and thus the hazard of skin breakdown. Methods. A randomized controlled trial was performed to test the effect of a 4‐cm thermoactive viscoelastic foam overlay with a water‐filled warming mattress on the OR‐table (test OR‐table) compared with the standard OR‐table (a water‐filled warming mattress, no pressure‐reducing device) on the postoperative pressure ulcer incidence in cardiac surgery patients. Instruments. The pressure ulcer classification system of the European Pressure Ulcer Advisory Panel (EPUAP) was used for pressure ulcer grading. Results. The results show that patients lying on the 4‐cm thermoactive viscoelastic foam overlay suffer slightly more pressure ulcer (17·6%) than patients on the standard OR‐table without the foam overlay (11·1%). Because of the clinical relevance of the results, the randomized controlled trial was terminated after 175 patients at the interim analysis although the power calculation stated 350 patients. Conclusions. The combination of a 4‐cm viscoelastic foam overlay and a warming source cannot be recommended for pressure ulcer prevention on the operating room table. Relevance to clinical practice. Foam overlays are used to prevent pressure ulcers in patients. It is necessary to use such devices according to patient safety and use of resources.
