NURSING INTERVENTIONS:HEALING DECUBITUS ULCERS WITH TENS

这项研究的目的是为了确定 经皮神经电刺激对压疮愈合的影响 溃疡。具体地说，这项研究的目的是：(1)比较 传统疗法治疗压疮的疗效观察 而那些接受常规治疗的患者则增加了 TENS，以及(2)比较溃疡愈合率和 特定的患者变量或溃疡情况变量。 样本将包括40名受试者，年龄在18岁及以上， 至少有一处压疮已经抵抗了 治愈至少三个月。受试者将从 退伍军人管理机构的住院病房，将是 随机分配到两种治疗方法之一。一 将对他们的压疮进行常规治疗 包括用湿润的细网纱布填塞溃疡 用0.25%的醋酸，并用一层棉花覆盖 装满了4x4的调味汁。调味料一年换三次 白天(上午、中午和晚上)。第二组将收到 对他们的溃疡进行相同的常规治疗并结合 TENS每天申请三次30分钟。主题将是 随访8周或直到他们的溃疡愈合。速度 愈合情况将通过每周测量溃疡来确定。 周长、表面积、深度和表面特征。 将测量溃疡周长、表面积和深度。 利用立体照相测量法，提出了一种遥测三元的方法。 使用立体照相对进行尺寸测量 使用计算机化的图像处理器进行分析。溃疡 表面特征将通过直接观察和 通过摄影。还将收集有关类型和类型的数据 支持性治疗的时间安排和患者的在场 可能影响死亡率的变量和溃疡情况变量 治愈。一组按时间重复测量的方差分析 将用于检查治愈率的差异 组。将应用弗里德曼双向方差分析 确定两组患者溃疡表面特征的差异 治疗组。在治疗组内，患者和溃疡 条件变量将与以下方面的差异相关 治愈率的量度。

The purpose of this study is to detemrine the effectiveness of transcutaneous nerve stimulation (TENS) on healing of decubitus ulcers. Specifically, the study will aim to: (1) compare the rate of healing of decubitus ulcers treated with conventional therapy and those treated with conventional therapy augmented with TENS, and (2) compare the rate of ulcer healing and the presence of specific patient variables or ulcer condition variables. The sample will consist of 40 subjects, 18 years of age and older, who have at least one decubitus ulcer that has been resistant to healing for at least three months. Subjects will be obtained from in-patient units of a Veterans' Administration facility and will be randomly assigned to one of two treatment approaches. One group will receive conventional treatment to their decubitus ulcer consisting of packing the ulcer with fine mesh gauze dampened with .25% acetic acid and covering it with a single layer of cotton filled 4 x 4 dressing. The dressing will be changed three times a day (morning, midday and evening). The second group will receive the same conventional treatment to their ulcer combined with TENS applied for 30 minutes three times per day. Subjects will be followed for eight weeks or until their ulcer heals. Rate of healing will be determined by weekly measurement of ulcer circumference, surface area, depth and surface characteristics. Ulcer circumference, surface area, and depth will be measured with sterophotogram-metry, a method of remote three- dimensional measurement using steroscopic pairs of photographs that are analyzed using a computerized image processor. Ulcer surface characteristics will be assessed by direct observation and by photography. Data will also be collected on the type and scheduling of supportive therapies and the presence of patient variables and ulcer condition variables that may influence rate of healing. A group by time repeated measures analysis of variance will be used to examine differences in rate of healing treatment groups. A Friedman two-way analysis of variance will be applied to determine differences in ulcer surface characteristics between the treatment groups. Within treatment groups, patient and ulcer condition variables will be correlated with differences in measures of rate of healing.
