Wound contact layers (WCLs) are intended to protect and support wounds during the healing process. An open, non comparative, case series clinical evaluation was undertaken to assess the impact of these dressings on establishing an undisturbed wound environment that supports effective wound management, and to allow the establishment of limits of duration of the wear time for the experimental WCLs.
The primary objectives of this clinical evaluation were to assess the ability of the WCLs to prevent tissue disturbance to the wound and surrounding skin and for the clinicians to have confidence to extend the wear time of the WCL dressings. For them to have confidence in leaving the dressings in place for extended periods, the assessment of the wound and periwound skin condition and an assessment of patient comfort was performed: assessment of wound and periwound condition in relation to tissue adherence of the dressing to the wound resulting in tissue damage/bleeding (to wound and/or periwound skin) and cellular infiltration into the WCL; assessment of patient wearing comfort and satisfaction; assessment of WCL wear time, relating to times between dressing changes as judged by the clinician.
Based upon five parameters used to assess the extent to which the WCLs Atrauman, Atrauman Silicone and Atrauman Ag (HARTMANN, Germany) disturbed the underlying tissues-bleeding, wound tissue damage, periwound skin damage, tissue ingrowth and dressing adherence-the majority (>95%) of assessments indicated low or no disturbance of tissue. Over the 14 days of study assessment, the mean (±standard deviation) wear time was 7.3±1.2 days for the Atrauman group, 9.9±2.8 days for the Atrauman Silicone group, and 5.8±1.0 days for the Atrauman Ag group. All dressings were well tolerated by patients and rated highly in terms of in-use dressing performance.
The results indicate that Atrauman WCLs are suitable for the management of a variety of wounds as they promote an undisturbed wound environment, including extended wear time.
伤口接触层（WCL）旨在保护和支持伤口在愈合过程中的愈合。进行了一项开放、非比较、病例系列临床评估，以评估这些敷料对建立一个不受干扰的伤口环境的影响，该环境支持有效的伤口管理，并确定实验性 WCL 的穿戴时间的持续时间限制。
该临床评估的主要目的是评估 WCL 防止伤口和周围皮肤组织受到干扰的能力，以及让临床医生有信心延长 WCL 敷料的佩戴时间。为了让他们有信心将敷料长时间留在原处，对伤口和周围皮肤状况以及患者舒适度进行了评估：评估与敷料对伤口的组织粘附导致组织损伤/出血（伤口和/或周围皮肤）以及细胞浸润到 WCL 相关的伤口和周围皮肤状况；评估患者佩戴舒适度和满意度；评估 WCL 的佩戴时间，与临床医生判断的敷料更换之间的时间有关。
基于用于评估 WCL 对底层组织干扰程度的五个参数——出血、伤口组织损伤、周围皮肤损伤、组织内生长和敷料粘附——大多数（>95%）评估结果表明对组织的低或无干扰。在 14 天的研究评估中，阿特曼（Atrauman）、阿特曼硅胶（Atrauman Silicone）和阿特曼银（Atrauman Ag）组的平均（±标准差）佩戴时间分别为 7.3±1.2 天、9.9±2.8 天和 5.8±1.0 天。所有敷料均被患者耐受良好，并在使用中的敷料性能方面获得高度评价。
结果表明，阿特曼 WCL 适用于多种伤口的管理，因为它们促进了一个不受干扰的伤口环境，包括延长的佩戴时间。
