Efficacy of D33 Sealed Foam in Preventing Skin Injury from Surgical Positioning: Randomized Clinical Trial.

Abstract

Objective: To evaluate the efficacy of density-33 (D33) sealed foam in preventing skin injuries from surgical positioning. Approach: The study, reported according to the Consolidated Standards of Reporting Trials, is characterized as a randomized clinical trial, double mask, with 64 adult patients undergoing elective surgery, 35 allocated to the control group (CG), positioned on a conventional surgical table, and 29 to the experimental group (EG), positioned on a conventional surgical table overlaid with a D33 sealed foam support surface (SS) in the occipital, sacral, and heel regions. Simple randomization was carried out, as was masking of the researcher who evaluated the skin of the patient and the statistician. Data collection was carried out immediately preoperatively, intraoperatively, and postoperatively until the third day or until patient discharge. Statistical analysis included measures of association in contingency tables, χ², and relative risk to compare the incidence of injuries between groups. Results: Skin injuries were greater in the CG, with blanchable erythema being the main injury. The use of D33 sealed foam reduced the incidence of injury in the EG by 61.2% (relative risk: 0.39; 95% confidence interval: 0.220-0.684; p < 0.001). Innovation: One of the first clinical studies to demonstrate that using a D33 sealed foam SS decreased the incidence of blanchable erythema from surgical positioning. Conclusion: D33 sealed foam was effective in preventing skin injury from surgical positioning in patients undergoing elective surgeries.
