The study evaluated the effects of different techniques used to secure intravenous (i.v.) catheters. An angiocatheter attached to standard i.v. tubing was taped to human forearm using a standard taping method. A calibrated piezoelectric force transducer was attached to the i.v. tubing. The force applied along the longitudinal axis to pull out the taped catheter was measured and recorded on paper. Three tape types, Curity, Leukopor and Transpore, were evaluated alone, with benzoin skin pretreatment and with mastisol pretreatment. A randomized 3 x 3 block design with 20 replications per block was utilized, and a total of 180 pullout tests were performed on two adult volunteers. Without pretreatment, the forces required to dislodge catheters were (means +/- SEM) 46 +/- 2, 37 +/- 2 and 38 +/- 2 Newtons for Curity, Leukopor and Transpore tape, respectively. Corresponding values for mastisol pretreatment (64 +/- 1, 64 +/- 3 and 52 +/- 3 Newtons) were greater (P < 0.05) for each tape compared with benzoin (54 +/- 3, 53 +/- 2 and 40 +/- 2 Newtons) and no pretreatment. The most frequent failure mode for Transpore tape was by tape fracture, for Curity tape was by separation from the skin of tape and catheter as a single unit, and for Leukopor tape was by catheter separation while tape remained attached to skin (P < 0.001). The data suggest that the application of mastisol prior to taping i.v. catheters with Curity or Leukopor tape helps to minimize the risk of accidental dislodgement.
该研究评估了用于固定静脉（i.v.）导管的不同技术的效果。将连接到标准i.v.输液管的血管导管使用标准粘贴方法粘贴到人的前臂上。将一个校准的压电式力传感器连接到i.v.输液管上。测量并记录沿纵向轴线施加的拔出粘贴导管的力，并记录在纸上。单独评估了三种胶带类型，即Curity、Leukopor和Transpore，以及使用安息香皮肤预处理和使用马替溶胶预处理的情况。采用随机3×3区组设计，每个区组进行20次重复，对两名成年志愿者共进行了180次拔出试验。在未进行预处理的情况下，对于Curity、Leukopor和Transpore胶带，拔出导管所需的力分别为（平均值±标准误）46±2、37±2和38±2牛顿。与安息香预处理（54±3、53±2和40±2牛顿）和未进行预处理相比，马替溶胶预处理（64±1、64±3和52±3牛顿）时每种胶带的相应值更大（P<0.05）。Transpore胶带最常见的失效模式是胶带断裂，Curity胶带是胶带和导管作为一个整体与皮肤分离，Leukopor胶带是胶带仍附着在皮肤上而导管分离（P<0.001）。数据表明，在用Curity或Leukopor胶带粘贴i.v.导管之前应用马替溶胶有助于将意外移位的风险降至最低。
