一、收敛鼻粘膜,清除鼻道内分泌物:以10%盐酸麻黄素溶液浸湿棉片数块,分别置于鼻下甲和鼻中甲的周围,以消除粘膜肿胀,充分暴露鼻中道与鼻上道,并可使窦口粘膜消肿,有利于窦膣内分泌物的引流。如鼻道内已有脓性分泌物积聚,即可初步判断分泌物来自何窦,以供头位引流后的参考。然后清净鼻道内的脓性分泌物,直至鼻道内无脓液积聚为止。二、改变头位,引流窦腔内分泌物:由于副鼻窦开口部位不一,故应采用不同的头位,以利于分泌物的引流。检查上颌窦时,让患者将头俯垂于二膝之间,如检 First, the convergence of nasal mucosa, clear the nasal secretions: 10% hydrochloric acid ephedrine solution soaked pieces of cotton, respectively, placed under the nose and nose A in order to eliminate mucosal swelling, fully exposed nasal passages and Nasal Road, and can make mucosal swelling of the ostium, is conducive to sinus drainage of endocrine.
