ReviewOutpatient regional anesthesia for upper extremity surgery update (2005 to present) distal to shoulder.
Multiple different approaches to the brachial plexus are available for the regional anesthesiologist to provide successful anesthesia and analgesia for ambulatory surgery of the upper extremity. Although supraclavicular and infraclavicular blocks are faster to perform than axillary blocks, the operator needs to keep in mind that blocks performed around the clavicle carry the risk for specific side effects and complications, no matter whether ultrasound or nerve stimulation is the chosen modality for neurolocation. ⋯ Smaller interventions such as carpal tunnel release or trigger finger release can be performed under elbow, wrist, or digital blocks. The regional anesthesiologist should strive to develop a tailored plan for each individual case to provide the most effective and safest nerve block technique for their patients.

ReviewRegional anesthesia procedures for shoulder and upper arm surgery upper extremity update--2005 to present.
This review of the literature since 2005 assesses developments of RA techniques commonly used for shoulder surgery, and their effectiveness for postoperative analgesia. Advantages of regional techniques include site-specific anesthesia and decreased postoperative opioid use. For shoulder surgeries, the ISB provides effective analgesia with minimal complications, whereas the impacts of IA single-injections remain unclear. ⋯ Since 2005, perineural catheters have been an analgesic option that offers improved pain relief among other benefits, and are now being used at home. It is clear that patients benefit greatly from a single injection and continuous nerve block for postoperative pain management,but the financial and logistical aspects need to be resolved, not to mention the phrenic hemiparesis coin toss. Whether combined perineural analgesic adjuvants prolong low-concentration LA nerve blocks sufficiently to render brachial plexus catheters as unnecessary would certainly represent another quantum leap.
