简介:瞄准:在二个不同耐心的位置调查在食道的测压法和pH加速方法之间的协议。方法:十八个题目在学习被包括。首先,到更低的食道的括约肌(LES)的近似边阶的从鼻子的距离被测量压力计的联盟者。然后一个不同调查者,被使看不见第一研究的结果,用pH加速方法测量了一样的距离,与病人在一起正直并且背卧位。对在二种技术之间的同意的一个评价被执行。结果:在背卧位,仅仅一个题目的测量在为正确的放接受的范围(对LES3厘米远侧或近似的<=)外面。在正直的位置,在测量的错误在五个题目被认出。Bland-Altman阴谋表明在大小之间的好同意获得了压力计的联盟者并且由在与在背卧位的病人一起的方法上面的pH步。结论:在情况中非压力计的察觉设备的可获得性,pH加速方法能便于放在背卧位与病人一起监视导管的24hpH。如果我们的结果被进一步的研究支持,这应该与怀疑的胃的食道的倒流疾病为题目在临床的实践增加pH-metry的使用。
