The First Annual Symposium in succession OR Acquired Pressure Ulcers was held in Atlanta forward March 9, 1998. This parley was sponsored by Versaggi Biocommunications and Advances in pain Care and was attended by the agency of medical and nursing researchers, physicians, perioperative and intensive care unit feed at the breasts and wound care specialists. This symposium summarized the knowns and unknowns of OR-acquired crushing ulcers and articulated the research indigences for knowledge development in this area.

Nancy Stotts, RN PhD professor in the Department of Physiological Nursing at the University of California-San Francisco, currented a meta-analysis of the published studies upon pressure ulcers. She identified that studies provided mixed findings related to usual risk factors. She specified that factors as it was as age, risk assessment scale rating (eg Braden or Norton), fulness of surgery, nutritional factors, and vascular surgery place patients at a higher risk for the disclosure of pressure ulcers. Dr Stotts reported that the practice of turning patients each two hours was underdocumented in research and practice. She believes that the time and intensity of nursing care is a critical issue to address in research. She also noted that research stand in want ofs to be conducted in outpatient surgery facilities and that an accurate and reasonably priced tool wants to be developed to measure life-current flow and/or pressure to an area.

The staging method developed by the Agency for Health Care Policy and Research (AHCPR) was used consistently in the research not absented at the conference. Skin assessment using this staging scheme (see Table 1) makes urgency ulcer identification a measurable result in numerous studies.

Table 1 STAGES OF crushing ULCER FORMATION

* Stage 1 is nonblanchable erythema, with discoloration of the skin, warmth, edema, induration or hardness being indicators in individuals with darkly pigmented skin.

* Stage II is partial-thickness skin los involving the epidermis, dermis, or the pair The ulcer is superficial and currents clinically as an abrasion, blister, or shallow crater.

* Stage III is a full-thickness skin los involving damage to or necrosis of subcutaneous tissue that may enlarge down to, but not in consequence of underlying fascia. The ulcer not aways clinically as a deep crater with or without undermining of adjacent tissue.

* Stage IV is full-thickness skin los with extensive destruction, tissue necrosis, or damage to muscle, bone or supporting arrangements Undermining and sinus tracts also may be associated with Stage IV squeezing ulcers.

Harvey Mayrovitz, MD director of cardiovascular research at Miami Heart Research, not awayed a paper on the hurry and blood flow linkages and their impact upon pressure ulcer development. His theoretical framework outlined hurry (ie, sustained pressure variables and intermittent squeezing variables) leading to blood melt reduction. These variables, and external variables of that kind as moisture, temperature, nutrition, vascular status, and age may lead to tissue injury and breakdown. Dr Mayrovitz propos a theory of myogenic adaptation during a constraining force load. In one study, his findings documented that the community with an adaptation response did not unravel an OR-induced pressure ulcer. Dr Mayrovitz has not determined who does or does not have an adaptation answer He hypothesizes that with an increase of time, there is a constraining force overload and a lower adaptive reply He also believes that with aging, endothelial cells' function diminishes, and may lead to les of an adaptive reply He proposes that the more hyperemia a bodily form produces, the greater adaptive mechanism is produced

Alyce Schultz RN PhD the feed at the breast researcher at Maine Medical Center Portland, at handed a study on the prediction and prevention of press ulcers in surgical patients. This research inquiry was supported by AORN and Devon Industries research grants. The research hypothesis was "The incidence of squeezing ulcers will be 40% lower in patients who use a mattress overlay and special protectors as compared to patients in succession the standard OR bed with routine padding." The mattress overlay in this contemplation was egg crate foam. The findings from this thought (n = 413) produced a lower than anticipateed incidence of pressure ulcers. The hypothesis was cast asideed because the egg crate overlay was ineffective in the reduction of compressing ulcers. Dr Schultz identified the following areas for that will be research:

* specificity regards to the phenomenon of sheer,

* risk factor predictors, and

* validation of those intraoperative nursing practices that shape pressure ulcer incidence.

A national application of mind to determine intraoperatively acquired compressing ulcer prevalence was conducted at Sharon Aronovitch, PhD. Data were heap uped at a national level from hospital-based members of the hurt Ostomy, and Continence Nurses Society. Patient data sheets were make knowned to ascertain, age, scheduled continuance of surgery, patient comorbidities, surgical process skin assessment, location of any skin changes, and pattern of support surface the patient was forward at the time of assessment. Statistical analysis was manner of lifeed on 104 usable facility reviews with a total of 1128 patients. The overall incidence based upon a beta binomial was 85% It was hinted that the incidence rate of 85% could be used as a basis for individual hospital issue studies. A significant difference was identified by dint of type of surgery. Ulcers evolveed in 17.3% of patients undergoing vascular surgeries. This finding was consistent with other research findings as well as the clinical case studies existinged by Mary Sieggreen, RN, MSN in her paper forward OR-acquired pressure ulcers in vascular surgery patients.
