“…To examine both these processes, we not only measured peak pressures but also the PPI, which is the mean pressure over a 14.5-cm 2 area. 24 The PPI values for the sacrum on both the standard long spineboard and the vacuum mattress were close to peak pressure, indicating that the peak pressure is not redistributed over the contact site. This leaves areas of high pressure over the sacrum, which is the body region most susceptible to developing pressure ulcers.…”

: This study revealed a relevant reduction in tissue-interface pressures and discomfort when using a soft-layered long spineboard compared with using a standard rigid long spineboard or a vacuum mattress. Emergency care providers should consider the use of the soft-layered long spineboard to reduce the discomfort and potential tissue damage caused by immobilization and transport on a rigid long spineboard or vacuum mattress.

“…Improved padding and mattresses on the operating table may contribute to lower postoperative CK levels and subsequently decrease the risk of organ failure. Keller and colleagues recently demonstrated in a randomized control trial that fluid mattresses are most effective in reducing interface pressure 10 .…”

OBJECTIVE: Several cases of highly elevated serum levels of creatine kinase (CK) after surgical interventions have been described in the literature. A consensus on possible risk factors is still lacking. We therefore studied CK-levels in a large population of patients undergoing neurosurgical interventions and sought to determine possible risk factors. METHODS: We retrospectively analyzed 150 elective neurosurgical interventions where pre-and postoperative CK serum levels were determined. The cases were selected such that 50 patients were operated in lateral position and 100 in prone or supine position. During the hospital stay, routine clinical diagnostics were conducted, including medical status and laboratory examinations. RESULTS: In the patient group (median age 50, 63 male) there were 129 cranial and 21 spinal interventions. In 55 cases, intraoperative neurophysiological monitoring (IONM) was performed so that in these patients muscles were not relaxed pharmacologically. In a linear regression model, the maximal postoperative CK-level increased compared to baseline (p<0.001). While age and obesity were not identified as risk factors, the CK-level was enhanced after surgery in lateral position (p<0.001) and if IONM was performed (p=0.04). CONCLUSIONS: The strong association of postoperative serum CK-level with intraoperative positioning and IONM may be related to the elevated body pressure on the operating table in the lateral position, in particular if muscles are not relaxed pharmacologically, which was the case if intraoperative monitoring was performed. In these cases special care has to be taken for the positioning and during the peri-operative management.

“…Clinicians and researchers have sought a reliable method to distinguish between blanching and nonblanching erythema to confirm Category I pressure ulcers (Bader & White, 1998;Clarys, Alewaeters, Lambrecht, & Barel, 2000;Ek, 1987;Holloway & Watkins, 1977;Keller, van Overbeeke, & van der Werken, 2006;Kragelj, Jarm, & Miklavcic, 2000;Schubert, 2000;Schubert, Perbeck, & Schubert, 1994;Sprigle, Linden, & Riordan, 2003). Nonblanching erythema can be falsely classified as a risk for pressure ulceration rather than as a Category I ulcer (Halfens et al, 2001;Lyder, 1991;Papanikolaou, Lyne, & Lycett, 2003).…”

Interface pressure measurement during surgery: a comparison of four operating table surfaces.

Abstract: As long as no reference values are available for interface pressures under which no pressure-related damage will occur, clinical testing of OR table surfaces is still necessary.
