超声流量计在新生儿潮气呼吸肺功能中应用 　　[摘要] 目的 运用超声流量法对新生儿进行潮气呼吸肺功能检测，探讨其在新生儿潮气呼吸肺功能中的应用，以建立不同体重新生儿潮气呼吸肺功能的参考值。 方法 选取深圳市儿童医院2010年7月～2013年12月住院并符合纳入标准的160例新生儿进行肺功能检测，按检测时体重分为极低体重组、低体重组、正常体重组、巨大儿组，对各组新生儿肺功能参数值进行统计学分析，计算其95%CI。 结果 新生儿体重越低，FRC、TV、TPEF/Te、VPEF/Ve、TEF75、TEF50、TEF25越低，RR则越高，各组之间TV/kg、MV差异无统计学意义。体重越低，TBFV环内面积越小，呼气曲线升支越陡峭，降支斜率较大。 结论 各组新生儿所测得肺容量、呼气流速、功能残气量值与目前国内外采用体积描述法研究所报道的数据一致，运用超声流量法检测新生儿肺功能的灵敏度高，所得数据可靠，且操作简便、重复性好，值得在新生儿肺功能检测中广泛应用。 　　[关键词] 超声流量计；新生儿；潮气呼吸肺功能 　　[中图分类号] R722[文献标识码] A[文章编号] 1674-4721（2014）04（c）-0008-04 　　 　　The use of ultrasonic flow meter in tidal breathing lung function test of neonatal 　　ZHANG Wei1,2 LIU Xiao-hong2▲ CAO Heng-heng1,2 LIU Yang1,2 　　1.Zhuhai Campus of Zunyi Medical University,Guangdong Province,Zhuhai 519090,China;2.Shenzhen Children′s Hospital,Shenzhen 518000,China 　　[Abstract] Objective To detection the tidal breathing lung function of neonatal by ultrasonic flow mete,to explore its application in neonatal moisture breathing lung function,in oder to establish the lung function parameters reference ranges of neonatal in different bodyweight. Methods 160 neonates were recruited from Shenzhen Children′s Hospital from July 2010 and December 2013,they were divided into 4 groups of very low body weight group,low body weight group,normal body weight group and giant body weight group according to the actual body weight.Groups of neonatal pulmonary function parameter values were statistical analyzed,the 95% confidence interval (95%CI) of parameters was calculated. Results The lower the birth weight,the FRC,TV,TPEF/Te,VPEF/Ve,TEF75,TEF50,TEF25 was lower,the RR was higher,TV/kg,MV differences between groups had no statistical significance.Within the lower weight,the TBFV loop area was small,exhale curve up the steep,descending slope was bigger. Conclusion The lung capacity,expiratory flow,functional residual capacity value in each group of neonatal and adopt the description method of volume at home and abroad research institute report data is
