The short measurement time with the VISITRAK system, and the ability to use it at the bedside, make it a useful, convenient device for clinical use.

BackgroundMost older adults with urinary incontinence use absorbent pads. Because of exposure to moisture and chemical irritating substances in urine, the perineal skin region is always at risk for development of incontinence-associated dermatitis (IAD). The aim of this study was to examine the efficacy of an improved absorbent pad against IAD.MethodsA cluster randomized controlled design was used to compare the efficacy of two absorbent pads. Female inpatients aged ≥65 years who had IAD and used an absorbent pad or diaper all day were enrolled. Healing rate of IAD and variables of skin barrier function such as skin pH and skin moisture were compared between the usual absorbent pad group (n = 30) and the test absorbent pad group (n = 30).ResultsThirteen patients (43.3%) from the test absorbent pad group and 4 patients (13.3%) from the usual absorbent pad group recovered completely from IAD. Moreover, the test absorbent pad group healed significantly faster than the usual absorbent pad group (p = 0.009). On the other hand, there were no significant differences between the two groups in skin barrier function.ConclusionThe test absorbent pad for older adults with urinary incontinence might be more efficacious against IAD than usual absorbent pad.Trial registrationUMIN-CTR: UMIN000006188

Skin care to minimise contamination and more effective ways of applying medical adhesive tape may be needed to prevent contact dermatitis.

Based on these results, the use of the vibrator may facilitate the healing of Stage I PrUs.

This finding suggests that the presence of diarrhoea is significantly related with contact dermatitis. Therefore, when a patient has diarrhoea, health-care professionals should immediately implement a preventative care program which includes careful skin observation and improved skin care. It is also necessary to develop a more effective absorbent pad to protect the skin of incontinent patients who suffer from the irritating effects of liquid stool.

The prognosis of stage I pressure ulcers cannot be predicted; therefore, nursing interventions for preventing their deterioration have not been clearly established. This study describes the clinical course of stage I pressure ulcers and prospectively investigates the factors related to their deterioration. Thirty-one stage I pressure ulcers in 30 patients in a long-term care facility were studied, and morphological changes were assessed every day until the ulcers healed or deteriorated. The physiological changes were assessed by ultrasonography and thermography. Twenty ulcers healed, and 11 deteriorated. The characteristics of deterioration were as follows: (1) double erythema; (2) non blanchable erythema across the whole area determined by glass plate compression; (3) erythema away from the tip of the bony prominence; and (4) expanding erythema on the following day. We analysed the sensitivity, specificity, positive predictive value, negative predictive value and positive likelihood ratio for the diagnostic utility of the indicators of deterioration double erythema and distance from the tip of bony prominence, which can be instantly assessed without the use of any special device. The values were 36.4%, 95.0%, 80.0%, 73.1% and 7.28, respectively. These results suggest that clinicians can predict the prognosis of stage I pressure ulcers by initial assessment and provide appropriate care based on the assessment.

Evaluation of wound fluid characteristics for pressure ulcer (PU) assessment in clinical settings remains subjective, requiring considerable expertise. This cross-sectional study focused on nutritional markers in wound fluid as possible objective tools and investigated whether they reflect the PU status according to the healing phase, infection, and granulation, especially after adjusting for serum values. Twenty-eight patients with 32 full-thickness PUs were studied. The concentration of albumin, total protein, glucose, and zinc in wound fluid were measured. For PU status, the healing phases and infection were evaluated by clinical signs, and the degree of granulation tissue formation was determined as the hydroxyproline concentration. The wound fluid/serum ratio for albumin was significantly lower during the inflammatory phase than during the proliferative phase (p=0.020). Infected wound fluid contained less glucose (0.3-1.0 mmol/L) than noninfected ones did (5.0-7.6 mmol/L) in an intraindividual comparison of three cases. The wound fluid/serum ratio for glucose was negatively correlated with hydroxyproline level in the proliferative phase (rho=-0.73, p=0.007), while zinc level in wound fluid showed a positive correlation (rho=0.61, p=0.028). Our results suggest that these traditional nutritional markers in wound fluid, especially wound fluid/serum ratio may be useful to evaluate local PU status.
