Abstract

目的 整理和评估国际临床实践指南(international clinical practice guidelines,CPG)以明确当前产房中早产儿呼吸支持的氧气管理的建议。 方法 使用临床实践指南、早产、氧气和复苏等关键词在公共数据库中检索文献,直接与共识制定组、复苏专家委员会和临床医生询问作为补充。采用的数据包括以下三个标准:数据来源国、胎龄和生后10分钟内起始FiO2和目标SpO2。 结果 总共有45个CPG纳入研究:36个设定有具体的胎龄(<28至<37周),其他8个只是区别了早产和足月。最常推荐初始FiO2供给在0.21~0.3之间(n=17)。大多数国家建议调整FiO2满足专家委员会推荐的目标SpO2,不过五分钟目标SpO2指南间差异达到了20%(70%~90%)。5个国家没有确定目标SpO2。 结论 CPG推荐的产房中早产儿氧气治疗差异较大,这些差异特别体现在对不同的胎龄、起始FiO2和目标SpO2,并且大多数意见缺乏有力的证据。需要大规模的精心设计的随机研究为这一重要临床需要提供支持。
