The purpose of the study was to compare the relative effectiveness of several combinations of tapes and taping methods with respect to the force required to pull out intravenous catheters. A simulated forearm model consisting of a section of firm PVC pipe was used for the first and second series of experiments. In the third experiment, one method of taping catheters was compared in the PVC model and in volunteers. Pullout forces were measured with a force transducer and recorded on paper. In the first experiment, catheters secured with Curity tape resisted pullout to a greater extent than those with Transpore tape and provided approximately twice the force advantage (P < 0.05). In the second experiment using Curity tape, minimum forces to dislodge the catheters were (means +/- SD) 53 +/- 13, 82 +/- 13, 113 +/- 29, 124 +/- 24, 176 +/- 29 and 141 +/- 46 N, for methods 1-6, respectively. In the third series, the minimum pullout forces were higher for Curity than with Transpore tape for both the human and simulated PVC forearm surfaces (63 +/- 11 and 55 +/- 12 N vs 52 +/- 7 and 44 +/- 12 N, P < 0.01), and the pullout forces were higher for the simulated vs. the human skin surface for both tape types (P < 0.01). Compared with Curity tape, Transpore tape was more likely to fail by tape fracture in both the simulated and human skin surfaces (P < 0.05). The data suggest that there are important differences in pullout forces and mechanisms of dislodgement depending on taping method and tape type.(ABSTRACT TRUNCATED AT 250 WORDS)
本研究的目的是比较几种胶带及粘贴方法的组合在拔出静脉导管所需力量方面的相对有效性。在第一和第二系列实验中，使用了由一段硬质聚氯乙烯（PVC）管组成的模拟前臂模型。在第三个实验中，对PVC模型和志愿者使用的一种粘贴导管的方法进行了比较。拔出力通过力传感器进行测量并记录在纸上。在第一个实验中，用Curity胶带固定的导管比用3M思高透明胶带固定的导管更能抵抗拔出，且提供了约两倍的力量优势（P < 0.05）。在使用Curity胶带的第二个实验中，方法1 - 6使导管移位的最小力量分别为（均值±标准差）53±13、82±13、113±29、124±24、176±29和141±46牛顿。在第三系列实验中，对于人体和模拟PVC前臂表面，Curity胶带的最小拔出力均高于3M思高透明胶带（分别为63±11和55±12牛顿对52±7和44±12牛顿，P < 0.01），并且对于两种胶带类型，模拟皮肤表面的拔出力均高于人体皮肤表面（P < 0.01）。与Curity胶带相比，在模拟和人体皮肤表面，3M思高透明胶带更易因胶带断裂而失效（P < 0.05）。数据表明，根据粘贴方法和胶带类型的不同，拔出力及移位机制存在重要差异。（摘要截选至250词）
