对60例婴幼儿支气管肺炎患儿,经雾化吸入、拍背后,采取经口腔与鼻腔吸痰,于雾化前及吸痰后分别经皮测血氧饱和度,其结果表明:经口腔与鼻腔吸痰后的血氧饱和度比雾化前均有明显升高;且经口腔吸痰比经鼻腔吸痰损伤明显减少.因此,经口腔吸痰效果好,损伤轻.“,”In 60 infants with bronchopneumonia, the blood oxygen saturation was subcutaneously determined by using the method of aspiration through oral and nasal cavity before aerosolization and after aspiration following the pattingback after the aerosolization aspiration. The results demonstrated that after the aspiration through oral and nasal cavity the blood oxygen saturation was obviously increased. And the damage by aspiration through oral cavity was significantly less than through nasal cavity. So it was concluded that the effectiveness was satisfactory and the damage was less by aspiration through oral cavity.
