病毒肺炎是怎么回事?

来源:华人健康网 | 发布时间:2010-11-14 23:31:02 | www.chinesejk.com

  腺病毒肺炎是小儿冬春季的常见病,可以散发或流行,尤其是在北方地区多见,这种肺炎比其他原因引起的支气管肺炎病情要重,而且容易发展为迁延性肺炎或慢性肺炎,对小儿危害较大。

  患病时一般都有高热,体温39-40℃,持续数天不退。咳嗽重,开始为频繁干咳,无痰,3-6天后痰多。由于肺部大片炎变,呼吸面积减少,因而呼吸困难,缺氧严重,全身中毒症状也重。患儿于起病3-4天后出现精神萎靡、不进饮食、面色苍白发灰、四肢冰凉、腹胀,有时呕吐、腹泻。重症多合并心力衰竭,心音减弱,心跳快,肝脏增大。病情危重可并发中毒性脑病,表现为嗜睡、惊厥、昏迷。危重情况可持续10天-3周。死亡率较高,尤其在患其他病的恢复期中,又交叉感染了本病,更是危险。有的病儿还可发展成为慢性肺炎。
