摘　　要：目的　探讨仰俯卧位对早产儿肺功能的影响。方法　应用美国Ｂｉｃｏｒｅ 公司的ＣＰ１００新生儿肺功能监护仪，分别测定３０ 例健康早产儿［（ 胎龄３４．５±０．３）周，体重（１ ９０５±５２） ｇ］ 仰、俯卧位时肺功能。结果　俯卧位潮气量为（５．４００ ±０．２００）ｍｌｋｇ，明显高于仰卧位时的（４．７００ ±０．２００）ｍｌｋｇ（Ｐ＜ ０．０１）；俯卧位气道阻力为（３３．７５０ ±３．０００） ｍｍＨｇ（Ｌ·ｓ） ，明显低于仰卧位时的（４３．０００ ±４．０００）（Ｌ·ｓ）（ Ｐ＜ ０．０１） ；俯卧位动态肺顺应性为（３．３８０ ±０．１６０） ｍｌ（ｍｍＨｇ·ｋｇ） ，明显高于仰卧位时的（２．３８０±０．１１０） ｍｌ（ｍｍＨｇ·ｋｇ）（ Ｐ＜０．０１） ；仰俯卧位时呼吸频率、每分通气量、时间常数及呼吸功差异均无显著意义。结论　俯卧位可改善早产儿的潮气量和动态肺顺应性，降低气道阻力。提示俯卧位可能是改善早产儿肺功能的适宜体位。Objective To study the effects of prone and supine positions on pulmonary function in preterm neonates Methods Pulmonary functions in prone and supine positions were investigated by Biocore CP 100 neonatal pulmonary monitor in 30 preterm neonates Their gestational age was (34 5±0 3) weeks, and birth weight was (1 905± 52) grams Results Tidal volume and dynamic lung compliance in prone were significantly higher than those in supine position (5 400±0 200) ml/kg vs (4 700±0 200) ml/kg and (3 380±0 160) ml/[(mmHg·kg)(1 mmHg=0 133 kPa)] vs (2 380±0 110) ml/(mmHg·kg) ( P <0 01) Airway resistance in prone was lower than that in supine (33 750±3 000) mmHg/(L·sec) vs (43 000±4 000) mmHg/(L·sec) ( P < 0 01) There were no significant differences in respiratory rate, minute ventilation, time constant and work of breathing between the two positions Conclusion Pulmonary function of preterm neonates could be improved in prone position which might be a better rest position
