简介:摘要分娩为正常生理现象,故需给予一定的护理,而且近年来人们对护理要求也越来越高,因此需对分娩产妇给予更高质量的护理。本文对在我院分娩的产妇给予人性化护理,主要有人性化的入院接待,人性化的病房布置,心理护理及分娩护理等。护理后结果表明产妇对护理质量的总满意率高达98.2%,显著性高于往年水平,这说明人性化护理具有满意应用效果。
简介:目的明确乳腺癌旁腺体退化程度及乳腺内不同部位腺体退化一致性.方法选择2010年12月1日至2011年12月1日北京协和医院乳腺外科乳腺癌保乳改良根治术22例,测量88张HE染色切片乳腺小叶面积及小叶内腺泡数量,评估乳腺小叶退化程度.应用两变量相关分析考察乳腺小叶面积和小叶内腺泡数量间相关性;应用方差分析、列联表分析和信度分析考察不同位置腺体退化程度一致性(P<0.05).结果乳腺小叶平均面积(90248.5±56909.4)μm2,每个小叶平均含腺泡(25.68±18.86)个,乳腺小叶面积和小叶内腺泡数量具有显著相关性(Pearsonr=0.78,P<0.01).乳腺癌保乳改良根治术患者癌旁腺体退化程度具有一致性(方差分析小叶面积19例无差异,小叶面积/腺泡数量18例无差异;Kappa系数=0.65;组内相关系数ICC=0.73).结论乳腺癌旁腺体退化不全,表现为乳腺小叶面积大及腺泡数量多,且2者具有相关性.乳腺癌旁不同位置腺体退化程度基本一致,单点退化程度能代表全乳腺情况.
