RESUMO
BACKGROUND: Interscalene brachial plexus block is frequently utilized to provide perioperative analgesia to patients undergoing shoulder surgery to optimize recovery, minimize opioid consumption, and decrease overall hospital length of stay. The use of an indwelling perineural interscalene catheter provides extended analgesia and is efficacious in managing severe postoperative pain following major shoulder surgery. Currently, the only alternative to perineural catheters for extended analgesia with interscalene block involves the perineural infiltration of liposomal bupivacaine. However, there is limited published data regarding the overall analgesic effectiveness of using interscalene liposomal bupivacaine in the setting of shoulder surgery. METHODS: We performed a retrospective review of 43 patients in the acute trauma setting who underwent major shoulder surgery and received extended analgesia via perioperative interscalene brachial plexus block with either an indwelling continuous catheter or single-dose liposomal bupivacaine to determine if comparable analgesia can be achieved. The primary outcomes of interest were postoperative pain scores and opioid consumption. Due to the ability to titrate and bolus local anesthetic infusions to a desired clinical effect, we hypothesized that opioid consumption and pain scores would be lower when using the continuous catheter technique. RESULTS: After statistical analysis, our results demonstrated no significant difference between the two techniques in regards to opioid consumption as well as numeric pain scores during the 48-hour postoperative period, but did note a higher rate of complications with patients who received perineural interscalene continuous catheters. Secondary outcomes showed an increase in time required to complete the regional block procedure with the use of indwelling catheters. CONCLUSION: Interscalene brachial plexus block with liposomal bupivacaine may be a viable alternative to indwelling continuous catheters for providing extended analgesia in patients undergoing major shoulder surgery.
RESUMO
Surgeries and chronic pain states of the upper extremity are quite common and pose unique challenges for the clinical anesthesiology and pain specialists. Most innervation of the upper extremity involves the brachial plexus. The four most common brachial plexus blocks performed in clinical setting include the interscalene, supraclavicular, infraclavicular, and axillary brachial plexus blocks. These blocks are most commonly performed with the use of ultrasound-guided techniques, whereby analgesia is achieved by anesthetizing the brachial plexus at different levels such as the roots, divisions, cords, and branches. Additional regional anesthetic techniques for upper extremity surgery include wrist, intercostobrachial, and digital nerve blocks, which are most frequently performed using landmark anatomical techniques. This review provides a comprehensive summary of each of these blocks including anatomy, best practice techniques, and potential complications.

Hidradenitis suppurativa (HS) is a chronic inflammatory disease of the terminal hair follicle of the apocrine gland-bearing skin, presenting with inflamed nodules, abscesses, and sinus tracts. Autoimmune, genetic, and infectious factors have been implicated in its pathogenesis. HS can be managed medically using topical and systemic antibiotics and with tumor necrosis factor antibody therapy in severe cases. Surgical treatment can range from local excision, deroofing or excision of sinus tracts, or wide radical excision of severe lesions. Lesions can be severely painful on their own or following surgical resection. Patients may require opioid therapy due to pain from the lesions themselves or following painful surgical resection. Erector spinae block (ESB) is a recently developed plane block used for the management of pain located in the chest wall or the abdominal wall. Ultrasound guidance is used to guide placement of the needle tip between the transverse process at the desired dermatomal level and the erector spinae muscle group. Traditional descriptions of the ESB have been at the level of the fifth transverse process to treat chest wall pain; in this case report, we describe a novel use of ESB at the level of the second transverse process to treat axillary pain after surgical debridement of axillary HS.
