CHEST:使用比色二氧化碳测量仪进行张力性气胸空针减压

2017-06-02 xiangting MedSci原创

使用比色二氧化碳仪进行空针减压可以快速,有效,高精度地消除张力性气胸减压操作者偏倚。

张力性气胸空针减压的成功率是不稳定的,没有客观的措施评估减压的有效性。比色二氧化碳测量仪可以检测胸腔内二氧化碳,可用作评估空针减压有效性的简单测试。

30只猪由创伤引发张力性气胸(n = 15接受标准治疗,n = 15接受空针二氧化碳测量仪)。标准治疗胸廓开口术使用8cm血管导管进行(n = 15)。类似地,通过加入比色二氧化碳仪进行减压。记录减压的主观操作者评估,并将两种技术与可视胸腔镜真正的减压进行比较。计算受试者工作曲线下的面积,并用成对比较评估统计学显著性(p <0.05)。

与胸腔镜评估(真正减压)相比,空针比色二氧化碳检查减压检测被发现为100%准确(15/15次尝试)。此外,在100%(10/10次尝试)的情况下,它准确检测到气胸张力不足,无病理/空间占位病变。操作者9/15次试验(60%)检测到标准空针减压,在3/10次(30%)时检测到不存在张力气胸。使用比色法15/15(100%),使用标准治疗12/15(80%)次有真正的减压。操作者曲线下面积标准治疗为0.65,空针二氧化碳仪为1.0(p = 0.002)

使用比色二氧化碳仪进行空针减压可以快速,有效,高精度地消除张力性气胸减压操作者偏倚。这会改善这种威胁生命疾病的治疗质量。
