“…15 Thermography has been tested to detect latent inflammation in PUs, including those with critical colonization. 16 Nakagami et al reported that PUs were classified into two groups depending on whether the wound site temperature was lower or higher than the peri-wound skin temperature; a higher wound site temperature may imply the presence of critical colonization. 16 However, international studies on the mechanisms and effects of critical colonization are only in the early stages, and no interventional studies have focused on DTI and critical colonization with the aim of preventing PU deterioration or providing systematic protocols for the management of PUs.…”

Aims and objectives:We investigated the effectiveness and safety of an advanced pressure ulcer (PU) management protocol comprising 1) ultrasonography to assess the deep tissue, 2) use of a non-contact thermometer to detect critical colonization, 3) conservative sharp debridement, 4) dressing selection, 5) negative pressure wound therapy, and 6) vibration therapy in comparison with those of a conventional approach. Each protocol was followed by trained wound, ostomy, and continence nurses (WOCNs). Background: At present, there is no systematic PU management protocol for nurses that includes appropriate assessment and intervention techniques for deep tissue injury and critical colonization. In Japan, there is no such protocol that the nurses can follow without a physician's orders. Design and methods: This was a prospective non-randomized controlled trial. Over a 3-week period, we evaluated the effectiveness of an advanced protocol by comparing the PU severity and healing on the basis of the DESIGN-R scale and presence of patients' discomfort. We recruited ten WOCNs to follow the advanced protocol and 19 others as controls. Statistical analysis included a linear mixed-effects model and a logistic regression model. Results: In week 0-1, the advanced protocol was significantly associated with prevention of PU deterioration. Using the linear mixed-effects model, we observed a greater decrease in the DESIGN-R score (healing) in the advanced protocol group. There were no reports of excessive bleeding, pain or infection with the advanced protocol. Conclusion: Using the advanced protocol, WOCNs detected PU severity, assessed PUs, and treated PUs safely. This protocol prevented PU deterioration and/or facilitated wound healing. Relevance to clinical practice: With proper training, WOCNs can assess and treat PUs safer and quicker than when a physician's assessment is required, leading to an improvement in wound healing and prevention of PU deterioration.

“…Wearable temperature sensors are important as the temperature of the human body is considered as one of the main vital signs that are measured and monitored in hospital patients [1], with temperature being a useful method to detect various pathologies, including infection in wounds [2][3][4]. This work builds on previous studies that have created a wearable temperature sensing yarns [5,6].…”

Abstract:Body temperature is an important parameter to measure in a number of fields such as medicine and sport. In medicine temperature changes can indicate underlying pathologies such as wound infections, while in sport temperature can be associated to a change in performance. In both cases a wearable temperature monitoring solution is preferable. In earlier work a temperature sensing yarn has been developed and characterized. The yarns were constructed by embedding an off-the-shelf thermistor into a polymer resin micro-pod and then into the fibers of a yarn. This process created a temperature sensing yarn that was conformal, drapeable, mechanically resilient, and washable. This work builds on this early study with the purposes of identifying the steady state error bought about on the temperature measurements as a result of the polymer resin and yarn fibers. Here a wider range of temperatures than previously explored were investigated. Additionally two types of polymer resin with different thermal properties have been tested, with varying thicknesses, for the encapsulation of the thermistor. This provides useful additional information for optimizing the temperature sensing yarn design.

“…Although IR and LSCI techniques have been used previously to examine ulcerated tissue [8][9][10], low-frequency oscillations of temperature and blood flow related to vascular tone have yet to be assessed. We hypothesize that fluctuations in these parameters could be used as sensitive, non-invasive markers to quantify different aspects of vascular pathophysiology in the ulcer bed and surrounding tissues.…”

Infrared (IR) imaging and Laser Speckle Contrast Imaging (LSCI) were used to measure skin temperature and blood flow, respectively, in leg ulcers of sickle cell anemia patients. Regional maps of the power of oscillations were computed via Fast Fourier Transform within the ulcers and surrounding tissues. We hypothesize that measurements of regional oscillations of temperature and perfusion by IR imaging and LSCI, respectively, may be sensitive, quantitative, non-invasive markers for ulcer pathophysiology, including local vascular tone and functional connectivity between ulcers and surrounding tissues.
