“…Some investigators have suggested that operation time is proportional to the risk of pressure ulcers, which also indicates an increase in the risk of operation. Therefore, the risk of pressure ulcers may be reduced by ensuring sufficient preoperative planning; this would in turn facilitate a smooth surgical workflow and shorten the operation time as much as possible [ 10 – 12 ].…”

Pressure ulcers are a common complication of immobility and frequently occur in surgical patients. The occurrence of pressure ulcers is affected by many factors, such as operation time and position, anesthesia method, and postoperative nursing. The aim of this study was to investigate the Munro Pressure Ulcer Risk Assessment Scale’s value in predicting acute pressure ulcers in general anesthesia patients. This case-control study included patients who underwent more than 2 hours of general anesthesia in our hospital from January 2018 to December 2020. The case group comprised 42 patients who had pressure sores in surgical compression sites within 3 days after surgery. The control group consisted of 84 patients without acute pressure sores after surgery. Baseline patient data were compared between the two groups, and a logistic multivariate model was used to analyze potential risk factors for acute pressure ulcers. The Munro Pressure Ulcer Risk Assessment Scale scores and Braden scale scores were compared between the two groups during and after surgery. A receiver operating characteristic curve was used to evaluate the clinical value of the two scales (administered at the two time points) in predicting the occurrence of acute pressure ulcers after surgery. The operation and anesthesia times of patients in the case group were longer than those in the control group ( P < 0.05 ). The proportion of comatose patients and patients with diabetes were significantly higher in the case group. While the case group had higher Munro scores during and after surgery compared to the control group ( P < 0.05 ), Braden scores at the corresponding time points were lower ( P < 0.05 ). The following variables were identified as independent risk factors of acute pressure ulcers: prolonged operation time and anesthesia time, increase in Munro scores during and after operation, decrease in Braden scores during and after operation, and comatose status ( P < 0.05 ). The area under the receiver operating characteristic curve (AUC) of the postoperative Munro score for predicting postoperative pressure ulcer risk was 0.774; the sensitivity and specificity were 67.73% and 80.58%, respectively. The AUC of the intraoperative Braden score for predicting postoperative pressure ulcer risk was 0.836, with a sensitivity of 78.95% and specificity of 78.00%. The AUC of the postoperative Braden score for predicting postoperative pressure ulcer risk was 0.809, with a sensitivity of 73.58% and specificity of 64.26% ( P < 0.05 ). Our results indicate that the intraoperative Munro Pressure Ulcer Risk Assessment Scale is highly effective for predicting the risk of postoperative pressure ulcers in surgical patients who require general anesthesia.

“…The observed thermal modulation of skin friction supports the potential therapeutic benefits of skin cooling regarding minimising friction over vulnerable skin sites. Microclimate conditions at the interface between a loaded skin site at risk of damage (e.g., the sacrum) and a support surface (e.g., a hospital mattress) are commonly associated with ~38°C skin temperatures[35], which is equivalent to the warm-plate condition of the current study. Under this real-life scenario, both our 24°C- and 16°C-plate conditions would represent skin cooling stimuli for a warm, mechanically loaded skin site and they could provide meaningful decreases in friction in a dose-dependent fashion (i.e., −23% at 24°C and −35% at 16°C), resulting from short periods of pre-conditioning (i.e., 60s).…”

Preliminary human studies show that reduced skin temperature minimises the risk of mechanically-induced skin damage. However, the mechanisms by which cooling enhances skin tolerance to pressure and shear remain poorly understood. We hypothesized that skin cooling below thermo-neutral conditions will decrease friction at the skin-material interface. To test our hypothesis, we measured the friction coefficient of a thermally pre-conditioned index finger sliding at a normal load (5N) across a plate maintained at three different temperatures (38, 24, and 16°C). To quantify the temperature distribution of the skin tissue, we used 3D surface scanning and Optical Coherence Tomography to develop an anatomically-representative thermal model of the finger. Our data indicated that the sliding finger with thermally affected tissues (up to 8mm depth) experienced significantly (p<0.01) lower frictional forces at 16°C-plate temperature than at the 24°C [-23% (19% SD)] and 38°C plate interactions [-35% (11% SD)], respectively. This phenomenon occurred without changes in skin hydration during sliding. Accordingly, our experiments demonstrate thermal modulation of skin friction in the absence of skin-moisture effects. Our complementary experimental and theoretical results provide new insight into thermal modulation of skin friction that can be employed for developing thermal technologies to maintain skin integrity under mechanical loading.

“…This localised change of climate reduces skin stiffness; hence the skin succumbs to the formation of PU. [40][41][42] On the other hand, skin dryness due to cell necrosis leads to reduced oxygen and blood flow, thus resulting in a fall in localised temperature. 41,43 Hence there are observations in both ways; rise or decrease in temperature during PU by various researchers.…”

Pressure ulcer (PU) is one of the most common occurrences in bedridden subjects. Despite the standard of care, there is a huge challenge in monitoring immobile subjects in all the bodily pressure points. This increases the chance of onset of PU which in turn increases the expenditure for treating and managing the PU. Hence, we made a study on the biological and physiological factors that are responsible for the formation of PU and also on various techniques used for diagnosis. Thus, we have summarised the efficacy of various advanced diagnostic procedures with their limitations. Though there are advanced imaging techniques, risk assessment tools based on the visual inspection are widely followed in hospitals. Based on our observation, we here have identified three major areas; one being the development of mathematical modeling, the second is towards the development of non-invasive devices and finally to automate cot facility. We have also provided possible suggestions as to solutions that could be useful to researchers and for society. Thus, this review covers the present difficulty faced by bedridden subjects and respective care-takers along with the knowledge gap and a few suggestions as to future scope.
