目的 探讨仰、俯卧位对足月新生儿肺炎患儿肺功能的影响 ,寻求足月新生儿肺炎患儿的合理体位。方法 应用美国BicoreCP 10 0新生儿肺功能仪分别检测 30例新生儿肺炎患儿仰、俯卧位时的呼吸频率、潮气量、每分通气量、气道阻力、动态肺顺应性和呼吸功。结果 俯卧位呼吸频率和气道阻力明显低于仰卧位 [(4 4 .3±9.2bpm min)vs (4 8.0± 10 .6bpm min) ;(15 3.1± 5 0 .4 )cmH2 O (L .sec)vs (2 11.9± 6 3.1)cmH2 O (L .sec) ,差异有极显著性意义 ,P <0 .0 1];俯卧位潮气量、每分通气量、动态肺顺应性和呼吸功明显高于仰卧位 [(2 .2 9±0 .4 6ml kg)vs (1.6 5± 0 .5 0ml kg) ;(0 .0 95± 0 .0 2 4 )L (min .kg)vs (0 .0 75± 0 .0 2 2 )L (min .kg) ;(0 .6 2 1±0 .2 14 )ml (cmH2 O .kg)vs (0 .389± 0 .115 )ml (cmH2 O .kg) ;(8.9± 3.5 )gm (cm .kg)vs (5 .9± 2 .7)gm (cm .kg) ,差异有极显著性意义 ,P <0 .0 1]。结论 俯卧位可改善新生儿肺炎患儿潮气量、每分通气量和动态肺顺应性 ,降低呼吸频率和气道阻力 ,提示俯卧位是改善新生儿肺炎患儿肺功能的适宜体位。
Objective To investigate the effect of supine and prone position on pulmonary function in full-term neonates with pneumonia and to seek a reasonable position for full-term neonates with pneumonia. Methods The respiratory rate, tidal volume, ventilation per minute, airway resistance, dynamic lung compliance and respiration were detected in 30 children with neonatal pneumonia by using the American BicoreCP10 neonatal pulmonary function instrument. Results The prone-position respiration frequency and airway resistance were significantly lower than those in supine position [(44.3 ± 9.2bpm min vs vs 8.0 ± 10.6bpm min); (15 3.1 ± 5.04cmH 2 O ) vs (2 11.9 ± 6 3.1) cmH 2 O (L · sec), the difference was significant (P <0.01); prone position tidal volume, ventilation per minute, dynamic lung compliance and significant respiratory work Was significantly higher than that in supine position [(2.29 ± 0.46 ml) vs (1.6 ± 0.50 ml kg); (0.95 ± 0.024) L .0 75 ± 0 .0 2 2) L (min. Kg); (0.62 ± 0.224) ml (cmH2O. Kg) vs (0.389 ± 0.115) ml (8.9 ± 3.5) gm (cm · kg) vs (5.9 ± 2.7) gm (cm · kg), respectively. There was a significant difference between the two groups (P <0.01). Conclusion The prone position can improve the tidal volume, minute ventilation and dynamic lung compliance, reduce the respiratory rate and airway resistance in children with neonatal pneumonia, suggesting prone position is an appropriate position to improve pulmonary function in neonates with pneumonia.
