ReviewAdjuvants in clinical regional anesthesia practice: A comprehensive review.
Adjuvants are medications that work synergistically with local anesthetics to help enhance the duration and quality of analgesia in regional techniques. Regional anesthesia has become more prevalent as evidence continues to show efficacy, enhancement of patient care, increased patient satisfaction, and improved patient safety. Practitioners in the perioperative setting need to not only be familiar with regional techniques but also the medications used for them. ⋯ The aim of the present investigation, therefore, is to provide a comprehensive review of the most commonly used non-opioid adjuvants in clinical practice today. Regional adjuvants can improve patient safety, increase patient satisfaction, and enhance clinical efficacy. Future studies and best practice techniques can facilitate standardization of regional anesthesia adjuvant dosing when providing nerve blocks in clinical practice.

ReviewNovel utilization of fascial layer blocks in hip and knee procedures.
of review: Novel motor-sparing peripheral nerve blocks in hip and knee procedures are desirable. ⋯ Recent advancements in US have transformed the clinical performance of fascial layer blocks, evidenced in their novel indications in hip, knee, and spine analgesia. The combination of various motor-sparing fascial plane blocks providing different areas of innervation is particularly useful in fast-track hip and knee surgeries.

Opioid-free anesthesia (OFA) is emerging as a new stimulating research perspective. The rationale to propose OFA is based on the aim to avoid the negative impact of intraoperative opioid on a patient's postoperative outcomes and also on the physiology of pathways involved in intraoperative nociception. ⋯ OFA has been shown to be feasible but the literature is still scarce on the clinically meaningful benefits for patients as well as on the side effects and/or complications that might be associated with it. This review focused first on the physiology of nociception, the reasons for using or not using opioids during anesthesia, and then on the literature reporting evidence-based proofs of benefits/risks associated with OFA.

ReviewPostoperative pain management in the era of ERAS: An overview.
Enhanced recovery after surgery (ERAS) programmes are increasingly becoming standard of care for several surgical procedures. However, compliance with ERAS protocols including pain management protocols remains poor. ⋯ This approach should facilitate incorporation of pain management recommendations in an ERAS protocol and improve compliance with the protocols. This article presents an improved approach to developing pain management guidelines as well as a pragmatic approach to procedure-specific perioperative pain management that could be incorporated in an ERAS pathway.

ReviewPostoperative acute pain challenges in patients with cancer.
It is expected that the number of surgical procedures to diagnose, treat, and palliate cancers will increase in the near future. While many of those interventions can be performed with minimally invasive techniques, others require surgical large incisions and in some instances, they involve multiple areas of the body (i.e., tumor resections with flap reconstructions). Pain after major oncological procedures can be severe and many times difficult to treat as patients can present to the operating room with several conditions including preoperative pain (i.e., rapidly growing tumors and painful neuropathies), opioid tolerance, and contraindications to nonopioid analgesics or regional anesthesia. ⋯ Furthermore, it has been theorized that poorly treated pain is associated with cancer recurrence and a reduced survival. Lastly, recent research questions the oncological safety of robotic surgery in gynecological procedures and indicates the need of open surgeries, which will be associated with an increased risk in moderate-to-severe postoperative pain. In conclusion, the management of acute postoperative pain in patients with cancer can be challenging.
