JOP:比较经喉罩与气管插管给药治疗早产儿的疗效

2023-05-21 小文子 MedSci原创 发表于海南省

经LMA给予表面活性剂治疗不劣于ETT给药,它减少了早期治疗失败,可能是通过避免给药前、喉镜检查和插管的不良反应。

早期表面活性剂治疗对呼吸窘迫综合征(RDS)婴儿有益,并可显著降低不良的肺部后果和死亡率。THE JOURNAL OF PEDIATRICS杂志发表了一项研究,评价经喉罩(LMA)和气管插管(ETT)给药在避免呼吸窘迫综合征(RDS)早产儿机械通气方面可能的非劣效性。

这项随机对照研究纳入妊娠27~36周出生的婴儿,出生体重>800g,诊断为RDS,需要无创呼吸支持,吸氧分数0.30~0.60,持续2h以上,以维持出生48h内血氧饱和度>88%。

婴儿被随机分配通过LMA或ETT接受表面活性剂治疗,ETT组婴儿在插管前接受0.01mg/kg阿托品和2mg/kg瑞芬太尼的术前用药,LMA组婴儿在插入1号LMA Unique(北美LMA)之前接受了阿托品的术前用药。主要结局是表面活性剂治疗失败,需要机械通气,即超过2剂表面活性剂治疗,持续需要FiO2 >0.60以维持目标氧饱和度,或第1次给药后8小时内再次给药。

结果纳入93例患者,随机分配51例LMA组和42例ETT组。两组的基线特征相似,出生体重810~3560g之间。

对主要结局(即表面活性剂治疗失败)的意向治疗分析显示,LMA组的失败率为20%,而ETT组为29%,RR=0.69(95%CI,0.33-1.43;P=0.314)。通过意向治疗进一步检查了失败时间,研究发现LMA组只有1名婴儿(2%)在表面活性剂给药1小时内需要机械通气,而ETT组有5名婴儿(12%)经历了早期治疗失败,具有统计学意义(P=0.044)。

LMA表面活性剂治疗不劣于ETT给药;失败风险差异为9.0%(CI,–∞~5.7%)。各组在减少吸氧量、表面活性剂剂量、停止呼吸支持时间、不良事件发生率以及包括肺气肿和支气管肺发育不良(BPD)诊断在内的结局方面的疗效没有差异。

结果表明,经LMA给予表面活性剂治疗不劣于ETT给药,它减少了早期治疗失败,可能是通过避免给药前、喉镜检查和插管的不良反应。这些特性使LMA成为表面活性剂给药的理想导管。
