支持重症监护床旁快速测量的血气分析仪

By LabMedica International staff writers
Posted on 30 Oct 2014
一种病人专用的新型内联式微型血气分析仪实现了近乎实时的测量,且能达到实验室分析仪的准确度,从而改进了重症监护。

英国剑桥市Sphere医疗用品公司生产创新性的重症监护和诊断设备,该公司在2014年9月17-19日于英国哈罗盖特举行的大不列颠与爱尔兰麻醉医师协会(AAGBI) 2014年度大会上发布了最新型的Proxima分析仪。Proxima微型血气分析仪在病人床旁快速、频繁地给出结果,实现了快速响应,改善了病人的预后,并降低了总体护理成本。

获得CE标志的Proxima系统是为重症监护环境设计的,它包括一台专用的床旁监护仪和联入病人动脉导管的Proxima传感器。这样可以在床旁直接测量血液参数,无需离开病人或操控样本和样本盒,从而减轻了一线护理人员的工作负担。结果的准确度可媲美实验室分析仪,结果很快显示在床旁监护仪上,并能以电子格式传输,以做永久记录。

Proxima使用简单,实现了封闭的血液采样,通过其床旁监护仪的触摸屏界面操作。当需要做血气分析时,从病人体内直接把血抽进Proxima传感器,无需打开导管、取样然后走开去分析。分析一完成,所有血液返回病人体内,因而保证保全血液,降低医院获得性贫血和之后输血的可能性。Proxima传感器是一种可抛型换能器,可用于监测72小时内的血气和电解质,并可根据要求监测任意多次。该系统还执行传统血气分析仪上所进行的全部质控检验,确保检验结果的有效性。

伯明翰大学医院的Tom Clutton-Brock大夫说:“在病人护理领域,数据的快速返回和对变化血气的快速响应与血压的连续测量同等重要。快速反馈和响应对高效地稳定患者或中断患者的机械通气有切实的影响。”Sphere医疗用品公司CEO Wolfgang Rencken说:“频繁测量动脉血样本是有效管理重症监护病人的要素,尤其是那些状况不稳定的患者。我们已经开发和发布了Proxima,使医务人员可以守在病人旁边,并保全血液,快速返回血气结果,辅助早期决策,更密切地控制危重症患者的治疗,上述所有方面将最终改善病人预后。”

Sphere医疗用品公司在AAGBI 2014上还赞助了一场行业讲座,由Clutton-Brock大夫作了题为“真实护理点检验”的报告,探讨重症监护室控制病人生理状态的困难,重点是动脉血样检验的理想频度以及相应的限制,如所需的人员时间、成本和血液保全。他还考虑了如果消除这些限制,情况将如何变化。
