机械通气早产儿二氧化碳分压的无创监测
在机械通气的早产儿中,监测二氧化碳分压 (pCO2) 值的能力是必不可少的。 pCO2 测量的金标准来自动脉血样 (paCO2)。 这有两个缺点:首先,它需要一条动脉管路,其次,它不能为临床医生提供连续测量。 目前,新生儿重症监护医学领域有两种可供选择的 pCO2 监测系统:呼气末二氧化碳 (etCO2) 二氧化碳图和经皮二氧化碳 (tcCO2) 测量。 这两种方法都有缺点,包括潜在的技术错误以及可能降低作为血气分析 (BGA) 替代品的可靠性的病理学。 特别是,传统的侧流 etCO2 二氧化碳图在存在管泄漏的情况下低估了 pCO2,这在仅使用没有袖带的管的通气早产儿中很常见。 通过双腔气管插管的远端 etCO2 (detCO2) 可以解决存在管泄漏时 etCO2 值不可靠的问题。
本研究的目的是比较 Kugelman 等人描述的远端 etCO2 测量技术的一致性、精确性和可重复性。关于机械通气早产儿的 paCO2 和 tcCO2。 由于不同中心的通气策略和 pCO2 限值可能不同,本研究有助于确定哪种无创 CO2 监测系统(detCO2 或 tcO2)在我们新生儿重症监护病房的早产儿的适用性和可靠性方面更合适。

详细说明
背景:在机械通气的早产儿中,监测二氧化碳分压 (pCO2) 值的能力是必不可少的。 pCO2 测量的金标准来自动脉血样 (paCO2)。 这有两个缺点:首先,它需要一条动脉管路,其次,它不能为临床医生提供连续测量。 目前,新生儿重症监护医学领域有两种可供选择的 pCO2 监测系统:呼气末二氧化碳 (etCO2) 二氧化碳图和经皮二氧化碳 (tcCO2) 测量。 这两种方法都有缺点,包括潜在的技术错误以及可能降低作为血气分析 (BGA) 替代品的可靠性的病理学。 特别是,传统的侧流 etCO2 二氧化碳图在存在管泄漏的情况下低估了 pCO2,这在仅使用没有袖带的管的通气早产儿中很常见。 通过双腔气管插管的远端 etCO2 (detCO2) 可以解决存在管泄漏时 etCO2 值不可靠的问题。
几项研究同时比较了 etCO2 和 tcCO2 与 paCO2。 在一组重症儿童中进行的 etCO2 和 tcCO2 比较研究未显示在没有严重肺实质疾病的情况下存在显着差异。 Tobias 等人比较了 etCO2 和 tcCO2 在呼吸衰竭儿科重症监护患者队列中的应用,发现 tcCO2 测量值更准确。 在一组通气新生儿中,在新生儿转运过程中,tcCO2 监测通常比 etCO2 更精确以监测通气。 在最近的一项仅限于一组没有肺部疾病的术后新生儿的研究中,etCO2 比 tcCO2 低估了 paCO2,但提供了比 paCO2 更高的精度,但是在较小的潮气量下它不太准确。 这些研究的共同点是 pCO2 分析仪的适配器在线连接并靠近气管插管。
研究目的:本研究的目的是比较 Kugelman 等人描述的远端 etCO2 测量技术的一致性、精确性和可重复性。关于机械通气早产儿的 paCO2 和 tcCO2。 由于不同中心的通气策略和 pCO2 限值可能不同,本研究有助于确定哪种无创 CO2 监测系统(detCO2 或 tcO2)在我们新生儿重症监护病房的早产儿的适用性和可靠性方面更合适。
