Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial with medical device is to learn if the Smart Needle Monitoring System works to maintain a safe low injection pressure during a type of regional anaesthetic (Peripheral Nerve Block (PNB)) in patients due to undergo surgery below the elbow . It will also learn about the safety of the device and patients' perception of the quality of anesthesia.

Participants will:

* be operated locally according to standard clinical practice
* undergo post-anesthesia recovery and any neurologic symptoms or signs assessment on postoperative days 1 and 7

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Smart Needle displaying

The Smart Needle Monitoring System is used to perform the ultrasound-guided axillary block. The monitor connected to the Smart Needle will display real-time and record the injection pressure profile during the entire PNB procedure.

The anesthesiologist will use the real-time visual feedback to maintain a low injection pressure profile (i.e., not higher than 15 psi) and avoid pressure peaks. The anesthesiologist can immediately stop the injection if there is a sudden increase in pressure, reposition the needle and start again, while always maintaining a low injection pressure profile

Group Type EXPERIMENTAL

Smart Needle Monitoring System

Intervention Type DEVICE

The Smart Needle Monitoring System is used to perform the ultrasound-guided axillary block. The monitor connected to the Smart Needle will display real-time and record the injection pressure profile during the entire PNB procedure

Smart Needle flipped

The Smart Needle Monitoring System is used to perform the ultrasound-guided axillary block. The monitor connected to the Smart Needle will be flipped allowing the recording of the injection pressure but not the real-time visualization by the anesthesiologist, who will perform the procedure as usual without a pressure visual feedback

Group Type OTHER

Smart Needle Monitoring System

Intervention Type DEVICE

The Smart Needle Monitoring System is used to perform the ultrasound-guided axillary block. The monitor connected to the Smart Needle will display real-time and record the injection pressure profile during the entire PNB procedure
