Background: Axillary brachial plexus block is widely used regional anesthesia technique for surgical procedure involving upper limbs. Ultrasound-guided Axillary Brachial Plexus Block (ABPB) provided the same fate and complication rates like nerve
stimulation option. Aim of the study: To compare the two techniques of double perivascular injection with the perineural method for axillary brachial plexus block, all guided by ultrasound using compare performance time, number of needle passes, complications, onset time, and success rate. Patient and method: A randomized clinical trial study conducted in the Orthopedics operating for a period of six months from July 2020 to June 2021. It included 60 adult patients scheduled for hand or wrist surgery with axillary brachial plexus block and randomly managed by either perineural or double perivascular infiltration techniques. Result: In this study, no difference among success rate duration of action and induction time were significantly longer in perineural group than that in double perivascular group. Proportion of patients that blocked by perineural procedure was significantly higher than double perivascular procedure. Conclusion: Both double perivascular and perineural ultrasound-guided ABPB are approximately having the same success rate. Double perivascular is less time consuming than perineural that may make it as alternative method.
