摘要:

Transcutaneous oxygen tension (TCPO2) is a recognized technique for evaluating support surfaces as a pressure ulcer prevention method. Transcutaneous oxygen tension was measured over the sacral area of 20 volunteers positioned on five different mattresses, including a standard mattress. No specific change was noted on resting values (M = 68.2 mm Hg, SD = 9.4) before each of the five protocols were begun. Mean values were 17.9 mm Hg(SD= 27.9) for a nonspecific hospital mattress, 30.15 mm Hg (SD = 29.5) for the first foam mattress, 30.25 mm Hg (SD = 28.5) for the second foam mattress, 50.5 mm Hg (SD = 23.1) for the air mattress, and 50.95 mm Hg (SD = 21.6) for the water-filled mattress.Results showed statistical differences between the standard mattress and the four mattresses tested and between the foam mattresses and the two other mattresses. There was an inverse correlation between skinfold thickness and a decreased TCPO2in contact area. Skinfold thickness could be an indicator of pressure ulcer risk. Further studies are needed to confirm the interest of this parameter.

摘要:

Despite a plethora of recommendations, protocols and dictums in the nursing literature, no research studies have defined the basic elements of preventive skin care for incontinent patients, and the prevalence of skin problems associated with incontinence is unknown. Yet the importance of skin care for incontinent elderly or immobilized patients has long been acknowledged.1–6This literature review sought to determine current practices and principles for skin care of frail, elderly, dependent, incontinent patients. Protocols vary widely. And although there is mounting evidence that incontinence, particularly fecal incontinence, is a primary risk factor for pressure ulcer development, most preventive efforts focus on pressure relief, repositioning, and nutrition, rather than incontinence care.More clinical trials are needed in this area. The design and analysis of these trials should take into account the frequency and manner in which skin is cleansed, products used for skin care, risks and benefits of absorbent products and devices, the presence of infection, and patients' concomitant medical conditions and degree of immobility.

摘要:

This study used an animal model to investigate whether exposure to intermittent noise affects wound healing. Forty male and female rats were anesthetized and received a 2.5×2.5-cm excisional wound on the back. For 19.5 days, 20 of the rats were exposed to periods of broad-band white noise ranging from 2 to 16 KHz. Data analysis revealed that the treatment group's wounds healed more slowly than the control group's (F = 12.64, p < .01). The rats' food intake and weights were also measured, and the treatment group's average weight was lower than the control group's (F = 18.94. p ≤.01), although food intake did not difter significantly for the two groups. The rats' gender had no apparent effect on the study results. Because this study used healthy animal subjects, more research is needed to determine if noise delays wound healing in hospitalized patients.
