The development of materials based in moist wound healing has meant an important step in wound care. The progressive development of knowledge referred to this issue has showed the importance of the management of wound exudate to obtain an optimal wound healing, which has concluded in a development of dressings orientated to manage exudate.
Experimental "in vitro" study to evaluate the absorption capacity and exudate management of three moist wound healing dressings, Allevyn Adhesive (dressing A), CombiDERM (dressing B) and Tielle (dressing C). For each of this dressings the following parameters have been assessed: rate between the total surface and the absorption surface of the dressing, volume needed to saturate the retention capacity, pH evolution on the absorption surface and macroscopic aspect.
Dressing A presents the major value in the rate between the total surface and the absorption surface (with a 64% rate, versus 28.7% for dressing B and 40.5% for dressing C). Dressing B was the one which needed a major quantity of exudate to saturate, with statistical significant differences versus dressings A and C (0.51 ml/cm2 versus 0.40 and 0.37 respectively). Dressing B was also the one that presented a best performance in reference to the leakage of exudate under pressure (with a loss of its initial weight of 8.34%, versus dressing C with a loss of 9.48%, and dressing A with a loss of 24.42%). None of the dressings presented pH modifications in the absorption surface.
The results of this study let us establish that according to the used experimental evaluation methodology and the limitations that have been described in the manuscript, the dressing which presents the best performance in reference to absorption capacity and management of wound exudate is dressing B (CombiDERM) followed by dressing A (Allevyn Adhesive) and dressing C (Tielle). Experimental and clinical research will be required to examine thoroughly the absorption capacity and management of wound exudate of these dressings.
基于湿性伤口愈合的材料发展是伤口护理领域的重要一步。关于这一问题的知识不断发展，已表明伤口渗出液管理对于实现最佳伤口愈合的重要性，这促成了旨在管理渗出液的敷料的发展。
进行“体外”实验研究，以评估三种湿性伤口愈合敷料（爱立敷粘性敷料（敷料A）、康倍德（敷料B）和缇艾尔（敷料C））的吸收能力和渗出液管理情况。对于每种敷料，评估了以下参数：敷料总表面积与吸收表面积的比率、使保留能力饱和所需的体积、吸收表面的pH值变化以及宏观外观。
敷料A在总表面积与吸收表面积的比率方面具有最大值（比率为64%，而敷料B为28.7%，敷料C为40.5%）。敷料B需要最大量的渗出液才能饱和，与敷料A和C相比具有统计学显著差异（分别为0.51 ml/cm²，而敷料A为0.40，敷料C为0.37）。在压力下渗出液渗漏方面，敷料B也表现最佳（初始重量损失8.34%，而敷料C损失9.48%，敷料A损失24.42%）。没有一种敷料在吸收表面出现pH值变化。
本研究结果使我们能够确定，根据所采用的实验评估方法以及手稿中所述的局限性，在吸收能力和伤口渗出液管理方面表现最佳的敷料是敷料B（康倍德），其次是敷料A（爱立敷粘性敷料）和敷料C（缇艾尔）。需要进行实验和临床研究，以全面检验这些敷料的吸收能力和伤口渗出液管理情况。
