摘  要:目的探讨滴定最佳呼吸系统动态顺应性(Cdyn)设定呼气末正压(PEEP)对急性呼吸窘迫综合征(ARDS)婴幼儿预后的影响。方法将广西壮族自治区妇幼保健院儿童重症监护病房(PICU)收治的30例ARDS婴幼儿按信封法随机分为对照组和治疗组,每组15例,分别使用美国ARDS协作网预先设定好的PEEP/吸入氧浓度(FiO2)对照表和滴定最佳Cdyn的方法设定PEEP,均采用压力控制通气(PCV)模式,小潮气量(7mL/kg)通气策略,监测2组患儿试验前及试验后呼吸力学、血流动力学、炎性因子等指标的变化,比较2组患儿机械通气时间、PICU住院时间及28d病死率。结果1.2组患儿性别、年龄、危重病例评分等一般情况比较差异无统计学意义(P均〉0.05)。2.根据PEEP/FiO2对照表设定的PEEP值明显低于滴定最佳Cdyn方法确定的PEEP值[(6.4±1.4)cmH2O(1cmH,0=0.098kPa)比(9.9±1.6)cmH2O,P〈0.01]。3.2组Cdyn、氧合指数(0I)均有好转,治疗组好转程度较对照组明显[Cdyn试验后2h:(0.39±0.03)mL/(cmH2O·kg)比(0。36±0.03)mL/(cmH2O·kg),P〈0.05;24h:(0.40±0.03)mL/(cmH2O·kg)比(0.38±0.03)mL/(cmH2O·kg),P〈0.05;48h:(0.43±0.02)mL/(cmH2O·kg)比(0.40±0.02)mL/(cmH2O·kg),P〈0.01;OI试验后24h:(20.07±2.12)cmH2O/mmHg(1mmHg=0.133kPa)比(21.94±2.05)cmH2O/mmHg,P〈0.05;48h:(17.51±1.64)cmH2O/mmHg比(19.82±2.07)cmH,O/mmHg,P〈0.01];试验前后2组心率(HR)、平均动脉压(MAP)、心脏指数(CI)等比较差异均无统计学意义(P〉0.05)。4.2组白细胞介素-6(IL-6)均呈进行性降低,治疗组降低程度较对照组更为明显[试验后24h:(84.58±9.11)ng/L比(93.18±9.27)ng/L,P〈0.05;48h:(76.67±9.23)ng/L比(90.10±9.42�Objective To investigate the impact of optimal respiratory system dynamic compliance (Cdyn) strategy for titrating positive endexpiratory pressure(PEEP) on the prognosis of acute respiratory distress syndrome (ARDS) in infants. Methods A total of 30 patients with ARDS admitted in Pediatric Intensive Care Unit ( PICU ) of Guangxi Maternity and Child Health Hospital were divided into 2 groups randomly (n = 15 ). PEEP was set in the control group according to PEEP/FiO2 in American ARDS collaboration while optimal Cdyn was for the treatment group. Pressure control ventilation(PCV) mode and small tidal volume( 7 mL/kg)strategy were taken. Respiratory mechanics, hemodynamies and inflammatory cytokines were monitored in each group before and after experiment. The time of assisted ventilation, and the hospital stay in PICU and 28 - day mortality were compared. Results ( 1 ) There was no significant differences in gender, age and severity of disease between the 2 groups ( all P 〉 0.05 ). (2) The optimal PEEP of the control group was significant lower than that of the treatment group[ (6.4 ± 1.4) cmH2O vs (9.9 ± 1.6) cmH20, P 〈 0.01 ]. (3)Cdyn and oxygenation index(OI) in 2 groups were all improved, and the degree of improvement in the treatment group was significantly better than that of the control group [ Cdyn after the experiment at 2 h : (0.39 ±0.03 ) mL/(cmH2O·kg) vs (0.36 ±0.03) mL/(cmH2O·kg),P 〈0.05; 24 h:(0.40±0.03) mL/(cmH2O·kg) vs (0.38±0. 03) mL/(cmH2O·kg), P 〈0. 05; 48 h: (0. 43 ±0. 02) mL/(cmH2O·kg) vs (0. 40 ± 0.02 ) mL/( cmH2O·kg), P 〈 0.01 ; OI after the experiment at 24 h : ( 20.07 ± 2.12 ) cmH20/mmHg vs ( 21.94 ± 2.05 ), P 〈 0.05 ; 48 h : ( 17.51± 1.64) cmH20/mmHgvs ( 19.82 ± 2.07 ) cmH2O/mmHg, P 〈 0.01 ] ; There were no significant differences in heart rate (HR), mean aterial pressure (MAP), cardiac index(CI) before and after the ex
