17、e system,Urinary catheter securement,導尿管固定好可降低尿管意外脫落，及由於過拉扯尿管或尿袋所造成的組織損傷及發炎尿管滑脫之比例為17%-41%，而不適當的固定是主要的危險因子，常引起沒有計劃性的尿管拔除。創傷及發炎與重複導尿管移動及尿道受壓有關，當尿管沒有適當固定或病人拉扯尿管會造成尿管沒有目的的移動，移動尿管會造成創傷及發炎，使其更容易造成感染、組織壞死、尿道腺體阻塞及膀胱不穩定或痙攣。,Urinary catheter securement,膠布是最古老的固定方法，將尿管黏貼於大腿或腹部，採chevron method ，即使臨床研究其固定效果不佳，然
18、在沒有其他選擇下，膠布仍然是主要固定尿管之方法。優點：便宜、方便缺點：易脫落常引起皮膚不同程度的反應重複的膠布使用，使得尿管感覺黏黏的，微生物即容易聚積在上面，而增加管腔外染污之危險性，使微生物進而進入膀胱引起泌尿道感染。,Maintaining a closed urinary drainage system,Urinary catheter securement,導尿管固定帶Dale Foley Catheter Holder,Urinary catheter securement,導尿管固定帶為專利產品，利用容易鬆綁之魔鬼膠帶，將導管固定，避免導管晃動拉扯脫出、感染，適合長期照護，急診手
