  "abstract": "Background and Aims Peripheral nerve injury from regional anaesthesia is rare but can have significant consequences. We audited the use of SAFIRA®, a novel device enabling single-operator peripheral nerve blockade (PNB). SAFIRA® automates injection of local anaesthetic (LA), stopping at a pre-set pressure to reduce the risk of nerve injury.Methods Twelve anaesthetists with varying experience trialled SAFIRA®. A target of 30 feedback responses was set. Users completed subjective evaluations after each use via virtual forms linked to QR codes on equipment.Results Of the blocks performed, 53% were by consultants, 24% by senior trainees, and 23% by junior trainees. 80% were upper limb blocks and 20% lower limb; no fascial plane blocks were recorded. All participants agreed that minimising nerve injury was extremely important. However, only 3% and 7% were extremely confident in their assistant’s delivery of correct LA volume and safe injection pressure, respectively. Over 80% used the foot pedal, the rest used the palm operator. 27% found SAFIRA® very easy to use; 63% said it became easier with practice. One anaesthetist found it difficult. 97% used the same or less LA volume than in two-person techniques, and 70% were highly confident in the device’s pressure control. 60% saw SAFIRA® as useful for training. Common criticisms included the need for extension tubing, device repositioning, and the lack of audible alerts.Abstract P122 Figure 1Type of block performedAbstract P122 Figure 2Volume of LA used with SAFIRA® compared to a standard two person techniqueAbstract P122 Figure 3Participant’s confidence in pressure at which LA is delivered when using SAFIRA®Conclusions SAFIRA® was well received, with usability improving over time. Suggested improvements include better ergonomic design and audio alerts to enhance user experience.",
