ReviewImpact of Regional Anesthesia on Recurrence, Metastasis, and Immune Response in Breast Cancer Surgery: A Systematic Review of the Literature.
The perioperative period is critical in the long-term prognosis of breast cancer patients. The use of regional anesthesia, such as paravertebral block (PVB), could be associated with improvements in long-term survival after breast cancer surgery by modulating the inflammatory and immune response associated with the surgical trauma, reducing opioid and general anesthetic consumption, and promoting cancer cells death by a direct effect of local anesthetics. ⋯ Our study indicates that there are no data to support or refute the use of PVB for reduction of cancer recurrence or improvement in cancer-related survival. However, PVB use is associated with lower levels of inflammation and a better immune response in comparison with general anesthesia and opioid-based analgesia.

ReviewAnesthesia and Analgesia Practice Pathway Options for Total Knee Arthroplasty: An Evidence-Based Review by the American and European Societies of Regional Anesthesia and Pain Medicine.
In 2014, the American Society of Regional Anesthesia and Pain Medicine in collaboration with the European Society of Regional Anaesthesia and Pain Therapy convened a group of experts to compare pathways for anesthetic and analgesic management for patients undergoing total knee arthroplasty in North America and Europe and to develop a practice pathway. This review is intended to be an analysis of the current literature to assist individuals and institutions in designing a pathway for total knee arthroplasty that is based on existing evidence and expert recommendation and may be customized according to individual settings.

ReviewChronic Poststernotomy Pain: Incidence, Risk Factors, Treatment, Prevention, and the Anesthesiologist's Role.
Chronic pain following median sternotomy is common after cardiac surgery. If left untreated, chronic sternal pain can reduce quality of life, affecting sleep, mood, activity level, and overall satisfaction. This has a significant societal effect given the large number of cardiac surgeries annually. ⋯ Moreover, the treatment of chronic poststernotomy pain is often inadequate, relying on opioids and other medications that provide minimal benefit to the patient and have significant adverse effects. Indeed, little is known regarding the prevention of chronic pain development following sternotomy. This review aims to present the current, limited data regarding the incidence, risk factors, treatment, and prevention of chronic poststernotomy pain and to identify areas of future research to improve management of this common complaint following cardiac surgery.

ReviewCadaveric Study of the Articular Branches of the Shoulder Joint.
This cadaveric study investigated the anatomic relationships of the articular branches of the suprascapular (SN), axillary (AN), and lateral pectoral nerves (LPN), which are potential targets for shoulder analgesia. ⋯ Articular branches from the SN, AN, and LPN were identified. Articular branches of the SN and AN insert into the capsule overlying the glenohumeral joint posteriorly. Articular branches of the LPN exist and innervate a portion of the anterior shoulder joint.

ReviewFocused Cardiac Ultrasound for the Regional Anesthesiologist and Pain Specialist.
This article in our point-of-care ultrasound (PoCUS) series discusses the benefits of focused cardiac ultrasound (FoCUS) for the regional anesthesiologist and pain specialist. Focused cardiac US is an important tool for all anesthesiologists assessing patients with critical conditions such as shock and cardiac arrest. However, given that ultrasound-guided regional anesthesia is emerging as the new standard of care, there is an expanding role for ultrasound in the perioperative setting for regional anesthesiologists to help improve patient assessment and management. ⋯ Postoperatively, FoCUS can help diagnose and manage common yet life-threatening complications such as pulmonary embolism or derangements in volume status. In this article, we introduce to the regional anesthesiologist interested in learning FoCUS the basic views (subcostal 4-chamber, subcostal inferior vena cava, parasternal short axis, parasternal long axis, and apical 4-chamber), as well as the relevant sonoanatomy. We will also use the I-AIM (Indication, Acquisition, Interpretation, and Medical decision making) framework to describe the clinical circumstances where FoCUS can help identify and manage obvious pathology relevant to the regional anesthesiologist and pain specialist, specifically severe aortic stenosis, hypovolemia, local anesthetic systemic toxicity, and massive pulmonary embolism.
