壓瘡是住院病患普遍的問題之一，不論就醫療品質或醫療、社會成本的考量，都是一個值得重視的議題。本研究目的在瞭解手術病患壓瘡之發生率以及發生手術後壓瘡之病患個人特質與手術特質等影響因素。研究設計採橫斷式調奎法，以方便取樣於北部某醫學中心手術室進行收案。研究工具包括自擬之個人特質、手術特質及壓瘡記錄表，自89年4月至10月止，共計收案983名。研究結果如下：手術病患手術後之壓瘡發生率為7%；個人特質中，病患年鹼、手術前的身體質量指數、"tota1 protein level" albumin值及Braden量表得分等變項為影響因子；而手術時間、麻醉種類、手術後體溫及手術中低血壓等手術特質會影響手術後壓瘡之發生。研究結果有助於手術全期護理之實務，並提供進一步實證研究的方向與基礎。
