摘要 目的探讨小潮气量通气(LTVV)在新生儿胎粪吸入综合征(MAS)所致呼吸衰竭治疗中的效果。方法回顾性分析新生儿重症监护室收治MAS所致呼吸衰竭患儿62例临床资料。比较小潮气量通气组(LTVV组,n=32)和传统机械通气组(CMV组,n=30)机械通气血气分析(pH、PaO2、PaCO2、SaO2)结果,治疗前后各时点氧合指数(OI)、动脉/肺泡氧分压比值(a/APO2)的变化,治疗过程中并发症[肺气漏、支气管肺发育不良(BPD)、脑出血]发生率及病死率,氧暴露及机械通气时间。结果两组机械通气24及48 h OI和a/APO2比较差异有统计学意义(P<0.05)。24 h时间位点血气分析结果:LTVV组pH低于CMV组,差异有统计学意义(P<0.01);LTVV组血PaCO2高于CMV组,差异有统计学意义(P<0.01);两组PaO2及SaO2差异无统计学意义(P>0.05)。LTVV组肺气漏、BPD等并发症发生率明显低于CMV组,差异有统计学意义(P<0.01);脑出血发生率差异无统计学意义(P>0.05)。LTVV组氧暴露及机械通气时间明显短于CMV组,差异有统计学意义(P<0.01),LTVV组病死率明显低于CMV组,差异有统计学意义(P<0.01)。结论 LTVV可显著改善患儿肺部氧合功能,降低机械通气肺气漏、BPD等并发症的发生率和机械通气时间及病死率。
