Trauma remains one of the largest problems that the global healthcare system faces today. In the United States it remains the leading cause of death for young and middle-aged patients, and its economic burden in direct cost and loss of productivity is tremendous. ⋯ The purpose of this review is to summarize the current state of pain control and opioid use in acute orthopaedic injury and provide an understanding of the role of PNB to improve pain management. Finally, this review provides a specific diagnosis-based treatment guideline for the use of PNB in acute orthopaedic injury.

ReviewRegional Anesthesia in Cardiac Surgery: An Overview of Fascial Plane Chest Wall Blocks.
Optimal analgesia is an integral part of enhanced recovery after surgery (ERAS) programs designed to improve patients' perioperative experience and outcomes. Regional anesthetic techniques in a form of various fascial plane chest wall blocks are an important adjunct to the optimal postoperative analgesia in cardiac surgery. The most common application of fascial plane chest wall blocks has been for minimally invasive cardiac surgical procedures. ⋯ Specifically, we focus on relevant anatomic considerations and technical descriptions including pectoralis I and II, serratus anterior, pectointercostal fascial, transverse thoracic muscle, and erector spine plane blocks. In addition, we provide a summary of reported local anesthetic doses used for these blocks and a current state of the literature investigating their efficacy, duration, and comparisons with standard practices. Finally, we hope to stimulate further research with a focus on delineating mechanisms of action of novel emerging blocks, appropriate dosing regimens, and subsequent analysis of their effect on patient outcomes.

ReviewAnaesthesia/analgesia for manual removal of retained placenta.
As a retained placenta is a potential life-threatening obstetrical complication, effective and timely management is important. The estimated mortality rates from a retained placenta in developing countries range from 3% to 9%. One possible factor contributing to the high mortality rates is a delay in initiating manual removal of the placenta. Effective anaesthesia or analgesia during this procedure will provide adequate uterine relaxation and pain control, enabling it to be carried out effectively. ⋯ There is insufficient evidence from one small study to evaluate the effectiveness and safety of anaesthesia or analgesia during the manual removal of a retained placenta. The quality of the available evidence was very low. We downgraded based on issues of limitations in study design (risk of bias) and imprecision (single study with small sample size, few or no events, and wide confidence intervals). There is a need for well-designed, multi-centre, randomised, controlled trials to evaluate the effectiveness and safety of different types of anaesthesia and analgesia during manual removal of a retained placenta. These studies could report on the important outcomes outlined in this review.

ReviewA Comprehensive Review of the Celiac Plexus Block for the Management of Chronic Abdominal Pain.
Chronic abdominal pain (CAP) is a significant health problem that can dramatically affect quality of life and survival. Pancreatic cancer is recognized as one of the most painful malignancies with 70-80% suffering from substantial pain, often unresponsive to typical medical management. Celiac plexus neurolysis and celiac plexus block (CPB) can be performed to mitigate pain through direct destruction or blockade of visceral afferent nerves. The objective of this manuscript is to provide a comprehensive review of the CPB as it pertains to CAP with a focus on the associated anatomy, indications, techniques, neurolysis/blocking agents, and complications observed in patients who undergo CPB for the treatment of CAP. ⋯ The CAP is difficult to manage due to lack of precision in diagnosis and limited evidence from available treatments. CAP can arise from both benign and malignant causes. Treatment options include pharmacologic, interventional, and biopsychosocial treatments. Opioid therapy is typically utilized for the treatment of CAP; however, opioid therapy is associated with multiple complications. CPB has successfully been used to treat a variety of conditions resulting in CAP. The majority of the literature specifically related to CPB is surrounding chronic pain associated with pancreatic cancer. The literature shows emerging evidence in managing CAP with CPB, specifically in pancreatic cancer. This review provides multiple aspects of CAP and CPB, including anatomy, medical necessity, indications, technical considerations, available evidence, and finally complications related to the management.

The objective of this review is to identify the potential of peripheral nerve blocks established over the last years for perioperative pain management in breast surgery. These new blocks will be discussed with respect to their clinical effect and necessity. ⋯ Taking the pain levels after breast surgery into account, the request of additional nerve blocks has to be pondered against the potential risks and resource requirement. To reduce or avoid intraoperative or postoperative opioids, an ultrasound-guided Pecs II block proves to be the best option for perioperative pain relief.
