《每周一问》活动目的有二，其一是为了让大家更好的学习和交流，其二是增加获得奖励的机会。每周一专家发帖提问，同周五专家公布答案。期间答对问题的用户将获得奖励，奖励多少由专家视情况而定，宠医帮的专家出手都挺大方的。
问题：上图显示了伤口有大量的渗液，下列哪种物料不适合用于中度至高度渗出的伤口？ The figure above shows a wound covered in exudate. Which of the following materials is not appropriate for use in a moderately to highly exudative wound? A.凡士林纱布 B.蜂蜜 C.糖 D.藻酸钙敷料 E.高渗盐水敷料 A. Petrolatum-impregnated gauze B. Honey C. Sugar D. Calcium alginate dressing E. Hypertonic saline dressing
正确答案是A 凡士林浸渍纱布不适用于伤口愈合的这一阶段，因为其不会吸收渗液。也不应使用聚四氟乙烯（特富龙）衬垫。此外，凡士林浸渍纱布以及聚四氟乙烯垫设计用于在修复阶段保护健康伤口，因为表面虽然完整，但上皮依然脆弱。两种产品都使伤口干燥，抑制肉芽组织形成。 蜂蜜、糖、藻酸钙和高渗盐水适用于炎症期和早期修复阶段的伤口，因为材料可吸收大量液体，同时保持健康、湿润的伤口环境，并鼓励伤口自体清创。此外，它们还能促进肉芽组织形成。由于蜂蜜含过氧化氢，还具有抗菌性。 Petrolatum-impregnated gauze is not appropriate to use in this phase of wound healing, as it does not absorb exudate.Teflon pads also should not be used. In addition, petrolatumimpregnated gauze, along with Teflon pads, were designed to protect a healthy wound in the repair phase, as there is an intact surface with a fragile epithelium. Both products are drying, which has an inhibitory effect on wound maturation to granulation tissue. Honey, sugar, calcium alginate, and hypertonic saline are indicated for use on wounds in the inflammatory phase and into the early repair stage, as the materials can absorb large volumes of fluid while maintaining a healthy, moist wound environment and encouraging autolytic wound debridement.In addition, they can promote granulation tissue formation.Because of its hydrogen peroxide content, honey also has antibacterial properties
