Basınç Ülserleri
Özet
Basınç ülserleri, genellikle kemik çıkıntıları üzerinde yoğun veya uzun süreli basınç ile makaslama ve sürtünme kuvvetlerinin etkisiyle meydana gelen lokalize deri ve yumuşak doku hasarlarıdır. Bu lezyonlar, özellikle hareket kabiliyeti kısıtlı veya duyu kaybı olan hastalarda yaygın olarak görülmekte ve küresel ölçekte önemli bir hasta güvenliği sorunu teşkil etmektedir. Ulusal Basınç Yaralanmaları Danışma Paneli (NPIAP) sistemi uyarınca yaralar, doku kaybının derinliğine bağlı olarak 1. dereceden 4. dereceye kadar sınıflandırılmakta; ayrıca evrelenemeyen ve derin doku yaralanması olarak da kategorize edilmektedir. Hastanede yatan bireylerde prevalansı %3 ila %14 arasında değişen bu durum, hastanede kalış sürelerini uzatarak sağlık sistemlerine yüksek ekonomik maliyetler yüklemektedir. Etyopatogenezinde dış basıncın kapiler basıncı aşmasıyla tetiklenen iskemi, nekroz ve reperfüzyon hasarı temel rol oynar. Bu nedenle yönetimde öncelikli hedef; beslenme desteği, pozisyon değişimi, nem dengesi ve uygun destek yüzeylerin kullanımıyla ülser oluşumunu engellemektir. Gelişmiş vakalarda ise pansumanlar, debridman, negatif basınçlı yara tedavisi ve elektrik stimülasyonu gibi konservatif yöntemler uygulanmakta, başarısızlık durumunda cerrahi müdahaleye başvurulmaktadır. multi-disipliner ve erken müdahale iyileşme sürelerini belirgin şekilde azaltmaktadır.
Pressure ulcers are localized damages to the skin and underlying soft tissue, typically occurring over bony prominences as a result of intense or prolonged pressure combined with shear and friction forces. These lesions are commonly observed in patients with restricted mobility or sensory loss, presenting a significant global patient safety concern. According to the National Pressure Injury Advisory Panel (NPIAP) system, these injuries are classified from Stage 1 to Stage 4 based on the depth of tissue loss, alongside unstageable and deep tissue pressure injuries. With a prevalence rate of 3% to 14% among hospitalized patients, pressure ulcers prolong hospital stays and impose high economic burdens on healthcare systems. The etiopathogenesis centers on ischemia, necrosis, and reperfusion injury triggered when external pressure exceeds capillary occlusion pressure. Consequently, the primary objective is prevention through nutritional support, repositioning, moisture balance, and appropriate support surfaces. Once ulcers develop, management strategies include specialized dressings, debridement, negative pressure wound therapy, and electrical stimulation. Surgical interventions such as skin or musculocutaneous flaps are indicated when conservative measures fail. Tailoring optimal treatment plans significantly reduces recovery times and prevents severe complications.
