Many conventional dressings are painful when removed, and may be detrimental to healing. In a pilot study ten consecutive abscesses, requiring incision and drainage, were packed with a calcium alginate dressing: this was well tolerated, its removal causing minimal pain. No adverse effects were attributable to its use. A controlled trial was therefore carried out to compare calcium alginate with the more traditional saline-soaked gauze for packing abscess cavities, following incision and drainage. Patients were randomized to receive either calcium alginate (16 patients) or gauze dressing (18 patients). At the first dressing change the patient marked on a linear analogue scale the pain experienced; the nurse noted similarly the ease of removal of the dressing. Calcium alginate was significantly less painful to remove after operation (P less than 0.01), and also easier to remove (P less than 0.01) than gauze dressings. If abscess cavities are packed after incision and drainage, calcium alginate appears to be an improvement on conventional dressings.
许多传统敷料在拆除时会引起疼痛，并且可能对愈合不利。在一项试点研究中，对连续10例需要切开引流的脓肿使用藻酸钙敷料进行填塞：患者对其耐受性良好，拆除时引起的疼痛极小。使用该敷料未出现不良反应。因此，开展了一项对照试验，比较藻酸钙敷料与更传统的盐水浸湿纱布在脓肿切开引流后填塞脓腔的效果。患者被随机分为两组，分别接受藻酸钙敷料（16例患者）或纱布敷料（18例患者）。在首次换药时，患者用线性模拟量表标记所经历的疼痛程度；护士同样记录拆除敷料的难易程度。术后拆除藻酸钙敷料时的疼痛明显较轻（P<0.01），而且比纱布敷料更容易拆除（P<0.01）。如果在脓肿切开引流后填塞脓腔，藻酸钙敷料似乎比传统敷料有所改进。
