Abstract

Purpose

To evaluate the in vivo accuracy of the new Pressio® device for intraparenchymal monitoring of intracranial pressure (ICP) versus the Codman® device and intraventricular measurement external ventricular drainage (EVD).

Methods

Data were collected retrospectively for 30 consecutive patients admitted into a 25-bed neurosurgical intensive care unit of a university hospital between January and December 2009. Patients received both intraventricular and intraparenchymal ICP monitoring with Pressio® (n = 15) or Codman® (n = 15).

Results

We obtained 3,089 data points from the 30 patients. Mean difference between intraparenchymal and EVD pressure (bias) was −0.6 mmHg, and limits of agreement (1.96 SD of the bias) were −8.1 to 6.9 mmHg with Pressio® and 0.3 mmHg with limits of agreement of −6.7 to 7.1 mmHg with Codman® (NS). The temporal difference was −0.7 ± 1.6 mmHg/100 h of monitoring with Pressio® and 0.1 ± 1.6 mmHg/100 h of monitoring with Codman® over the study period (NS).

Conclusions

Intraparenchymal pressure measured with both transducers approximates intraventricular cerebrospinal fluid pressure with an accuracy of ±7 mmHg.
