下肢動脈潰瘍護理處置原則

The Principle of Management for Lower Extremity Arterial Ulceration

下肢無法癒合之潰瘍傷口常見於複雜性病因，如：糖尿病、週邊動脈疾病，引發週邊血管阻塞而形成潰瘍性傷口，進而影響病患及照護者的生活品質及醫療支出甚鉅。本文目的為透過文獻整理提供醫療專業人員有關動脈潰瘍傷口相關的病理生理變化、危險因素、診斷、評估、治療及傷口照護策略，期望相關人員能對動脈潰瘍傷口照護有所了解及關注此相關議題，進而透過預防性策略去預防及減少因動脈血流灌注不足對潰瘍性傷口造成的影響。

A non-healing ulcer of the lower extremity may have many causes, such as diabetes and peripheral arterial disease. An ulcer is an obstructive condition where the flow of blood through peripheral arteries is impeded. Lower extremity ulcers impact the quality of life and increase the health expenses of patients and their caregivers. The purposes of this article were to provide physicians and nurses with an overview of the pathophysiology, risk factors, assessment, diagnosis, treatment and wound management strategy of arterial insufficiency and ulceration. This review article is intended for physicians and nurses with an understanding and interest in managing patients with arterial insufficiency and ulceration. Clinical nurses are encouraged to use proven strategies to prevent and decrease the impact of lower extremity ulcers with arterial insufficiency.
