The new 'Visual Pressure Control' (VPC) syringe by Pajunk offers a visual indication of the Loss of Resistance (LOR) during epidural procedures. This innovative VPC system serves as a dependable alternative to traditional LOR techniques, offering visual detection of even the most subtle pressure variations.
The result is a more objective needle tip placement and increased patient safety.
Simple and fast application without technique changes, independent of the tactile assessment
Simplifies epidural needle placement training and supervision process
Dependable position control of the cannula tip in epidural space
Even the smallest pressure differences are recognizable
Minimal amounts of saline injected into epidural space
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. A pressure column builds up in this capillary, which is visible in the magnifier. If, after the skin puncture, the VPC is connected to the epidural cannula and put under pressure by advancing the cannula, the pressure column in the magnifier rises. As long as a tissue pressure exists at the cannula tip, the pressure column in the capillary of the VPC is visible.
Once the surrounding pressure drops, indicating the epidural space has been reached, the pressure column in the display window will drop instantly, which is clearly visible in the magnifier of the capillary. The pressure drop can be easily replicated to confirm the correct cannula tip placement in the epidural space.
