16例婴幼儿肺炎合并呼吸衰竭患儿使用高频喷射通气,频率范围从110～160次/分,驱动氧压从0.8～0.5kg/cm~2。通气期间我们监测了病儿的心率、血压和血气分析,有13例PaO_2升高,PaCO_2下降并存活。3例死亡,其中1例在通气24小时后发生气道梗阻,可能与湿化不足有关。作者认为:高频通气对婴幼儿肺炎是有效的,但长期使用可能带来气道梗阻或损伤的危险。 16 cases of infantile pneumonia with respiratory failure using high-frequency jet ventilation, the frequency range from 110 to 160 beats / min, the driving oxygen pressure from 0.8 to 0.5kg / cm ~ 2. During the ventilation, we monitored the heart rate, blood pressure and blood gas analysis of sick children, 13 cases of PaO 2 increased, PaCO 2 decreased and survived. 3 died, of which 1 case of airway obstruction occurred 24 hours after ventilation, may be related to inadequate hygroscopy. The authors believe that: high-frequency ventilation is effective for infant pneumonia, but long-term use may lead to airway obstruction or injury risk.
