EpiLong VPC

Visual Pressure Control Device for Identification of the Epidural Space

The new “Visual Pressure Control” (VPC) by Pajunk developed in collaboration with Prof. Dr. med. Dietmar Enk and Dr. med. Günter Michaelis, offers a visual indication of the Loss of Resistance during epidural procedures. The VPC is a reliable alternative to the conventional Loss of Resistance technique, by visually indicating even the smallest pressure change. As a result, a more objective needle tip placement and increased patient safety are allowed.

EpiLong VPC Overview

EpiLong VPC: How it works

The VPC follows the principle of Boyle’s Law that states that the product of pressure and volume are constant. The VPC has a special plunger that comes with a built in capillary and integrated magnifier. Pressure builds up a column in this capillary, which is visible in the magnifier.

Preparing the VPC

VPC is delivered filled with 2ml of air

Drawing of 8ml of NaCl solution (0.9%)

Venting

Procedure

The VPC is pressurised by pushing the plunger forward. The pressure column (magnifying glass) rises.

The pressure column remains visible as long as tissue pressure remains at the tip of the needle.

When the epidural space is reached, the characteristic loss of resistance becomes visible by a clearly recognisable drop of the pressure column in the magnifying glass of the capillary.

Comparison

Bimanual needle guidance facilitates application, the piston can be released. The pressure column shows the slightest pressure differences and enables a reliable position control of the needle tip.

Reaching the epidural space (loss of resistance) is visualised, independent of tactile assessment. Only small amounts of liquid are injected.
