《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。
问题一只9岁的被诊断为1级软组织肉瘤的大丹犬,切除胫骨近端内侧15 cm组织。http://www.vetgroup.cn/forum.php?mod=viewthread&tid=27198&extra=
用绷带包扎(胫骨内侧手术伤口部分闭合,部分保持开放)的切口部位,在首次更换绷带时,一期闭合区域裂开,伤口被渗液覆盖。对该区域进行彻底冲洗。 以下哪种冲洗溶液可以降低伤口感染率? A.无菌生理盐水 B.自来水 C.蒸馏水 D.这些溶液的感染率无差异
The incision site in Question 3 (surgical wound on the medial tibia partially closed and partially left open) was bandaged and at the first bandage change, the areas of primary closure had dehisced and the wound was covered in exudate. The area was thoroughly lavaged. Which of the following lavage solutions can result in a lower wound infection rate? A. Sterile saline B. Tap water C. Distilled water D. Infection development does not differ for any of these solutions. 正确答案是D 在人体和动物中进行的多项研究显示,当使用这些溶液中的任何一种进行冲洗时,伤口感染无差异,这可能是因为冲洗的作用是通过物理方式清除严重污染。因此,溶液的无菌性或抗菌特性不如物理去除污染物重要。必须用大量液体冲洗伤口。 Multiple studies in humans and in animals show no difference in the development of wound infection when irrigated with any of these solutions, likely because the function of irrigation is to physically remove gross contamination. Sterility or antimicrobial properties of the solution are, therefore, less important than the physical removal of contaminants. Large volumes of fluid are considered more important when decontaminating a wound
