Injection pressure limiter

Avoiding nerve damage during peripheral nerve blocks
Ultrasound-guided localisation of peripheral nerves provide crucial benefits in regional anaesthesia.1) Nonetheless, it is clear that this does not reduce the incidence of permanent nerve damage.2) Even in combination with nerve stimulation, intrafascicular injections cannot be ruled out.1)3)4)5) With the automatic injection pressure limiter NerveGuard, PAJUNK® addresses the preventive position control to avert following damages.
