摘 要:目的探讨高频振荡通气联合肺表面活性物质(pulmonarysurfactant,PS)治疗新生儿胎粪吸人综合征(meconiumaspirationsyndrome,MAS)的临床疗效。方法回顾性分析2008年6月至2011年6月本院新生儿重症监护病房收治的53例MAS患儿的临床资料,根据治疗措施不同分为常频通气组23例,高频通气组18例,高频通气+PS组12例。方差分析及卡方检验比较3组通气治疗2、12、24、4:8h后肺氧合功能指标和呼吸机参数指标如氧合指数、动脉/肺泡氧分压比值(arterialoxygen/alveolaroxygenratio,a/Ap02)和吸入氧浓度(inspiredoxygenfraction,FiO2)的变化,以及患儿的呼吸机使用时间、住院时间、症状变化及转归情况。结果3组患儿机械通气前氧合指数、a/ApO。和FiO:差异无统计学意义。机械通气治疗2和48h后,常频通气组氧合指数分别为(23.79±7.27)和(15.04±4.76)mmHg;a/ApO2分别为0.11±0.04和0.31±0.07;Fi02分别为0.744-0.16和0.47±0.21。高频通气组氧合指数分别为(21.13±6.29)和(11.73±4.54)mmHg;a/Ap02分别为0.14±0.06和0.35±0.06;Fi02分别为0.68±0.14和0.41±0.11。高频通气4-PS组氧合指数分别为(18.35±5.68)和(7.85±5.06)mmHg;a/Ap02分别为0.17±0.03和0.40±0.02;FiO:分别为0.59±0.13和0.29±0.16。与常频通气组比较,高频通气组治疗后氧合指数、a/ApO:和FiO。有所好转,高频通气+PS组在时限和程度上比高频通气组好转更明显,差异均有统计学意义(P均〈0.05)。常频通气组患儿机械通气时间为(7.2±0.6)d,住院时间为(22.2±4.5)d,氧疗时间为(15.4±2.4)d;高频通气组较之缩短,分别为(4.2±4)、(15.6±3.4)和(11.8±5.3)d;高频通气+PS组最短,分别为(2.9±0.5)、(11.8±4.3)和(7.4±2.2)d,差异均有统计学�Objective To explore the clinical effects of high frequency oscillatory ventilation (HFOV) combined with pulmonary surfactant (PS) on neonatal meconium aspiration syndrome (MAS). Methods Data of 53 newborns with MAS admitted into the Neonatal Intensive Care Unit of Ning Bo Women and Children's Hospital from June 2008 to June 2011 were retrospectively analyzed. According to different therapeutic measures, they were divided into three groups: conventional mechanical ventilation (CMV) group (n=23), HFOV group (n= 18) and HFOV+PS group (n= 12). The oxygen index, arterial oxygen/alveolar oxygen ratio (a/ApO2) and inspired oxygen fraction (FiO2) were monitored at 2, 12, 24 and 48 h after mechanical ventilation. The mechanical ventilation time, duration of hospital stay, change of symptom, complications and clinical outcomes of the three groups were compared by analysis of variance and Chi-square test. Results The parameters of the three groups at 2 and 48 h after mechanical ventilation were as followed: CMV group [oxygen index: (23.792±7.27) and (15.04+_4.76) mm Hg a/ApO2 : 0.11±0.04 and 0.31± 0.07 FiO2 : 0. 74 ± 0.16 and 0.47±0.21], HFOV group [oxygen index: (21.13±6.29) and (11.73±4.54) mm Hg; a/ApO2 : 0.14±0. 06 and 0. 35 ± 0. 06% FiO2: 0.68±0.14 and 0.41±0.11] and HFOV-FPSgroup [oxygen index: (18.35± 5.68) and (7.85± 5.06) mm Hg; a/ApO2: 0.17±0.03 and 0. 40±0. 02; FiO2:0.59±0.13 and0.29±0.16]. Compared withCMVgroup, the parameters of HFOV group and HFOV-FPS group were different at different time points, and the parameters (duration and extent) of HFOV--PS group were better than those of HFOV group (all P〈20.05). The mechanical ventil.ation time was (7.2±0.6) days in CMV group, (4.2±1.4) days in HFOV group and (2.9±0.5) days in HFOV-FPS group; the hospital stay was (22.2±4.5) clays in CMV group, (15.6±3.4) days in HFOV group and (11.8~4.3) days in HFOV-I-PS group; and the ox
