<p>Comparison Of Digital Manometer And Water Column Manometer Pressures Measurements During Lumbar Puncture</p>

Abstract

BackgroundCerebrospinal 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.Research design and methodsThis 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.ResultsMean 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.ConclusionDigital 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.

Digital manometry to measure cerebrospinal fluid pressure during lumbar puncture

“…Further, the design employed a single provider who performed all LPs in order to maintain procedural consistency and limit confounding due to variation in technique. While the exact amount of time saved per case may vary among practitioners and institutions due to differences in procedural technique, the approximately fiveto sixfold comparative time savings of the digital device found in our investigation are similar to that found by Sekrhi et al 11 However, unlike Sekrhi et al's findings, we did not find that the digital manometer consistently produced a higher pressure measurement than the analog device.…”

“…A single preliminary study of 27 patients has been previously published. 11 Our study substantially contributes to the literature as it represents the largest investigation of this type to date. Further, the design employed a single provider who performed all LPs in order to maintain procedural consistency and limit confounding due to variation in technique.…”

Comparison of the Kron technique and digital manometry for measuring intra-abdominal pressure in emergency department patients diagnosed with ileus

“…Results from these devices correlate well with classical methods. [ 8 , 9 ] In our study, we used a digital manometer for IAP measurement, demonstrating a strong correlation with the gold standard method, significantly shorter measurement times, and reduced consumable use.…”

“…Fundus examination is noninvasive and may also be useful in this case but fundus changes occur several days after intracranial hypertension. Invasive methods of measuring intracranial pressure are less indicated in this case but can be done by lumbar manometer 6,9 .…”
