Block performance indices of perivascular and perineural techniques of ultrasound-guided axillary block in upper limb surgeries: A comparative study

Conclusion: The PV and PN techniques were comparable in terms of their success rates and total anesthesia-related times. The PN technique had higher success rate and faster block onset, but the PV provided a quicker performance time and fewer needle passes. Hence, PV technique may be preferable to PN for high-volume surgical units.
