Cerebrospinal fluid (CSF) pressure measurement is routinely performed via a conventional water column manometer. There is increasing interest in using a digital manometer in measuring CSF pressures. The aim of this study is to compare column and digital manometers, in addition to measuring time to acquire the pressure readings.
This prospective study included 27 patients who were referred for a fluoroscopically guided lumbar puncture. Opening pressure and closing pressure measurements were done with a digital manometer and then a traditional water column manometer. The time to obtain each pressure measurement was also recorded and compared.
Mean time to obtain pressure reading was significantly lower in the digital manometer group when compared to the water column manometer group (8.1 seconds vs. 42.2 seconds, P<0.05 for opening pressure and 8.92 seconds vs. 45.15 seconds, P<0.05 for closing pressure). Correlation between the opening pressure measurements (Pearson coefficient r= 0.98) and closing pressure (Pearson coefficient r= 0.89) was strong. However, the digital manometer reading consistently read higher.
Digital manometry during an LP yielded is faster however there might be a clinical difference between the devices. Clinicians must be careful in using the device across all cases.
脑脊液（CSF）压力测量通常通过传统的水柱压力计进行。使用数字压力计测量脑脊液压力的兴趣日益增加。本研究的目的是比较水柱压力计和数字压力计，同时测量获取压力读数的时间。
这项前瞻性研究纳入了27例因荧光镜引导下腰椎穿刺而转诊的患者。使用数字压力计测量初压和终压，然后再使用传统的水柱压力计进行测量。还记录并比较了获取每个压力测量值的时间。
与水柱压力计组相比，数字压力计组获取压力读数的平均时间显著更短（初压分别为8.1秒和42.2秒，P<0.05；终压分别为8.92秒和45.15秒，P<0.05）。初压测量值之间（Pearson系数r = 0.98）和终压测量值之间（Pearson系数r = 0.89）的相关性很强。然而，数字压力计的读数始终更高。
腰椎穿刺期间使用数字测压法速度更快，但两种设备之间可能存在临床差异。临床医生在所有病例中使用该设备时必须谨慎。
