Regional anaesthesia procedures typically require two operators – an anaesthetist who holds an ultrasound scanner and peripheral nerve block needle, using the ultrasound to  guide the needle tip placement. A second operator is then required to inject the anaesthetic solution.

It has been reported that anaesthetic solutions are often injected at high pressure.

High pressure can cause damage to nerve fascicles, with serious nerve damage occurring in up to 1% of procedures and transient nerve damage in up to 8% of cases [1,2].

The SAFIRA® system enables a single operator, an anaesthesia clinician, to conduct the whole regional block process at safer pressures.

A choice of two operators – a foot pedal or a palm operator – enables the clinician to control both infusion and aspiration themselves. The system facilitates consistent and controlled delivery of local anaesthetic.

A built-in safety mechanism automatically stops injection at a specified pressure threshold, helping to reduce the risk of nerve injury. Available with both Luer and NRFit connections.

The SAFIRA® system: Award winning technology

SAFIRA® was awarded ‘Patient Safety Innovation of the Year’ at the HSJ Patient Safety Awards 2021

The judges felt SAFIRA® was an outstanding example of healthcare innovation which clearly improved safety for patients and clearly demonstrated a reduction in a known risk, enhancing patient care.
