Pressure ulcers (PU) are caused when persistent pressure and/or friction/shear force is applied to an area of skin, generally over bony prominences, e.g., heel, trochanter, and sacrum, sufficient to impair the blood supply (National Health Service (NHS) Improvement, 2018; European Pressure Ulcer Advisory Panel (EPUAP), National Pressure Injury Advisory Panel (NPIAP), and Pan Pacific Pressure Injury Alliance (PPPIA), 2019). PUs are characterised on a severity scale that ranges from discoloured skin to open wounds with exposed underlying muscle and bone (NPUAP, 2017). Those at risk for the development of a PU are people that are unable to move regularly, especially the critically ill, the elderly, or anyone with a lack of sensory perception, e.g., spinal cord injury or neurological impairment. In addition, the condition of the soft tissue and its microclimate, as well as the nutrition status and comorbidities of the patient, can influence PU formation (NPUAP, 2017). Once a PU has developed, especially if it proves hard-to-heal, it can significantly impact on the quality of life of the patient. Patients report that their emotional, mental, physical, and social wellbeing is affected, especially when an PU proves hard to manage and fails to heal (Gorecki et al, 2012). Therefore, it is imperative that patients are provided with a comprehensive PU treatment plan that ensures the best possible healing outcome for the patient, with the best economic outcome for the healthcare provider.

Abstract: This case series investigates the recovery of chronic wounds treated with hyaluronic acid-collagenase (Hyalo4® Start), which facilitates enzymatic debridement, helping prepare the wound bed for healing and closure on top of first-line therapy. We recruited 15 patients with different underlying comorbidities who consented to participate in the case study. Selection criteria include patients with chronic wounds classified as Class 2 and Class 3 according to Harikrishna Periwound Skin Classification (HPSC). Treatment duration varied. The study observed a minimal to 100% reduction in wound size, notably diminished exudate excretion, healthy wound edge, and lower pain score as Hyalo4® Start was applied as part of standard care.

摘 要

目的：观察偏瘫患者下肢健侧与患侧的温度差异，并且分析可能导致出现这种差异现象的原因，提出相应的解决方法，为偏瘫患者的临床护理与治疗提供一定的理论支持和专业指导。方法：本文将应用ATIR-M301红外热像仪采集47名偏瘫患者下肢健侧和患侧的温度图像，并应用ATIR-M301红外热像仪自带的温度图像分析软件对偏瘫患者下肢的温度图像进行分析，得出数据，并对采集的数据进行统计学检验。结果：偏瘫患者下肢健侧温度与患侧温度比较有统计学意义(P < 0.05)。结论：偏瘫患者下肢健侧温度与患侧温度有差异，患侧温度比健侧温度低1℃~1.5℃。

Abstract

Objective: To observe the temperature difference between the healthy side and the affected side of the lower limbs of patients with hemiplegia, and analyze the possible causes of this difference, and propose the corresponding solutions, so as to provide certain theoretical support and professional guidance for the clinical nursing and treatment of patients with hemiplegia. Methods: In this paper, ATIR-M301 infrared thermal imager was used to collect the temperature images of the healthy side and the affected side of the lower limbs of 47 patients with hemiplegia, and the temperature image analysis software of ATIR-M301 infrared thermal imager was used to analyze the temperature images of the lower limbs of patients with hemiplegia, obtain the data, and conduct statistical test on the collected data. Results: The comparison between the healthy side temperature and the affected side temperature of the lower limbs in patients with hemiplegia was statistically significant (P < 0.05). Conclusion: In the patients with hemiplegia lower temperature and with the contralateral side temperature difference, the same temperature is lower than the contralateral temperature 1˚C~1.5˚C.
