【摘要】 目的:分析同步间歇性指令性通气(SIMV)叠加压力支持(PSV)治疗早产儿呼吸窘迫综合征的效果,为临床治疗提供参考。方法:选取笔者所在医院NICU收治早产儿呼吸窘迫综合征(NRDS)100例为研究对象,依照住院号单双号随机分为观察组和对照组,对照组给予SIMV治疗,观察组给予SIMV+PSV治疗。观察机械通气前后心率、动脉血压、氧合指数等变化,记录两组患者总通气时间、拔管时间。结果:相同时间点观察组患儿RR、PEEP、MAP值均显著低于对照组(P<0.05)。观察组设置呼吸频率值要明显低于对照组(P<0.05)。观察组患儿机械通气持续时间、拔管时间、脱机龄显著优于对照组(P<0.05),观察组并发症发生率明显少于对照组(P<0.05)。结论:SIMV+PSV治疗NRDS效果良好,能够缩短机械通气时间,具有应用价值。

【Abstract】 Objective:To analyze the efficacy of simultaneous indirect mandatory ventilation(SIMV) and superimposed pressure support(PSV) in the treatment of respiratory distress syndrome(RDS) in premature infants,so as to provide reference for clinical treatment.Method:100 cases of premature infants with respiratory distress syndrome(NRDS) were treated by NICU in our hospital.All premature infants were randomly divided into the observation group and the control group according to the number of hospitalization.The control group was treated with SIMV and the observation group was treated with SIMV+PSV.The changes of heart rate,arterial blood pressure and oxygenation index before and after mechanical ventilation were observed,and the total ventilation time and extubation time were recorded.Result:RR,PEEP and MAP in the observation group were significantly lower than those in the control group at the same time point(P<0.05).Set breathing frequency in the observation group was significantly lower than that in the control group(P<0.05).The duration of mechanical ventilation,extubation time and off-line age in the observation group were significantly better than those in the control group(P<0.05),and the incidence of complications in the observation group was significantly lower than that in the control group(P<0.05).Conclusion:SIMV+PSV is effective in the treatment of NRDS,and can shorten the mechanical ventilation time,which has application value.

NRDS多见于早产儿,胎龄越小,NRDS发生率越高[1]。NRDS病情危重,病死率极高[2],在当前治疗中,机械通气是抢救的重要治疗手段[3]。随着医疗技术的进步,应用于NRDS的机械通气治疗方法不断出现[4]。为提高NRDS早产儿生存率,笔者所在医院针对NRDS患儿实施两种不同的机械通气方法,评价SIMV+PSV模式疗效,现整理报告如下。
1 资料与方法
1.1 一般资料
选择笔者所在医院NICU的行机械通气的NRDS患儿100例为研究对象,入选标准:(1)出生胎龄≤36+6周,日龄≤1 d,临床诊断符合《实用新生儿学》第4版NRDS诊断标准;(2)持续气道正压(CPAP)失败[PEEP≥7 cm H2O,吸入氧浓度(FiO2)>60%,血氧分压(PaO2)<50 mm Hg];(3)严重呼吸暂停;(4)动脉血二氧化碳分压(PaCO2)>60 mm Hg,合并pH<7.25。排除标准:(1)重度窒息(5 min Apgar 评分<4分,或脐血pH<7.0);(2)严重畸形(严重先天性心脏病、膈疝、腭裂、先天性遗传代谢类疾病等);(3)严重感染;(4)宫腔感染肺炎;(5)出现肺出血或者持续肺动脉高压;(6)休克、多器官衰竭;(7)无自主呼吸;(8)机械通气不足24 h或放弃治疗。
根据入院时住院号(单、双号)进行随机分成观察组和对照组,观察组男27例,女23例,胎龄(30.26±1.26)周,出生体重(1 625.32±264.53)g,固尔苏(猪肺磷脂注射液)剂量(131.6±16.5)mg/kg。对照组男25例,女25例,胎龄(31.63±1.69)周,出生体重(1 596.34±247.61)g,固尔苏(猪肺磷脂注射液)剂量(125.6±14.7)mg/kg,两组一般资料差异无统计学意义(P>0.05),具有可比性。患儿家属均知情同意。
1.2 方法
两组基础治疗相同,包括保温、维持内环境稳定、营养支持、防治感染,部分应用多巴胺等心血管活性药物保证心血管功能稳定。所有……
