Foam alternatives to the standard hospital foam mattress can reduce the incidence of pressure ulcers in people at risk. The relative merits of AP and CLP devices and of the different AP devices for pressure ulcer prevention are unclear. There is some evidence from one study to suggest that LAL beds may reduce the incidence of pressure ulcers compared with standard intensive care beds. There is insufficient evidence to make conclusions on the value of various CLP devices and sheepskins as pressure ulcer prevention strategies, although Australian Medical Sheepskin was an effective preventive strategy in a recent study. There is evidence from two trials that air-fluidized therapy may improve pressure ulcer healing rates. There is insufficient evidence to make conclusions on the value of other beds and mattresses as pressure ulcer treatments. There is insufficient evidence to recommend any particular wound dressing or debridement technique. Research about pressure ulcer prevention and treatment is generally conducted on a small scale and is of poor quality; few economic evaluations have been undertaken of pressure area care strategies. Only when a clinically relevant research agenda has been developed and appropriate research methods have been used in sufficiently large studies can evidence-based pressure ulcer prevention and treatment be a possibility. Until then, nurses and other health care professionals can only rely on what little research evidence exists together with their professional judgment to make decisions in this field.
标准医院泡沫床垫的替代泡沫材料可降低高危人群中压疮的发生率。空气压力床垫(AP)和持续低压预防(CLP)装置以及不同AP装置在预防压疮方面的相对优点尚不清楚。一项研究的一些证据表明,与标准重症监护病床相比,低压空气床垫(LAL)床可能会降低压疮的发生率。尽管在最近一项研究中澳大利亚医用羊皮是一种有效的预防策略,但关于各种CLP装置和羊皮作为预防压疮策略的价值,仍缺乏足够证据得出结论。两项试验的证据表明,气悬浮疗法可能提高压疮愈合率。关于其他病床和床垫作为压疮治疗手段的价值,缺乏足够证据得出结论。对于推荐任何特定的伤口敷料或清创技术,证据不足。关于压疮预防和治疗的研究通常规模较小且质量较差;很少有对受压部位护理策略进行的经济学评估。只有当制定出具有临床相关性的研究议程,并在足够大的研究中使用适当的研究方法时,基于证据的压疮预防和治疗才有可能实现。在此之前,护士和其他医疗保健专业人员只能依靠现有的少量研究证据以及他们的专业判断来在该领域做出决策。
