Arterial blood gases, pulmonary mechanics, lung volume measurements and clinical profiles were determined pre and postextubation in 19 infants recovering from respiratory disease. This study evaluated clinical and physiological factors which may be valuable in predicting successful extubation in neonates. Of the 19 patients, 4 required reintubation within 72 h. In this group of patients, the combined profile of low birth weight (1050 g), low gestational age (31 weeks), and high pulmonary resistance (inspiratory 278 cm H2O/L X sec, expiratory 309 cm H2O/L X sec) was significantly different from the 15 patients who were successfully extubated. In addition, lower pHa after extubation was also characteristic of those infants requiring reintubation.
对19名从呼吸道疾病中康复的婴儿在拔管前后进行了动脉血气、肺力学、肺容积测量和临床特征评估。本研究评估了可能对预测新生儿拔管成功有价值的临床和生理因素。19名患者中，4名在72小时内需要重新插管。在这组患者中，低出生体重（1050克）、低胎龄（31周）和高肺阻力（吸气时278厘米水柱/升×秒，呼气时309厘米水柱/升×秒）的综合特征与15名成功拔管的患者有显著差异。此外，拔管后较低的动脉血pH值也是那些需要重新插管婴儿的特征。
