RESUMO
Training and expertise in regional anaesthesia have increased significantly in tandem with increased interest over the past two decades. This review outlines the most recent advances in regional anaesthesia and focuses on novel areas of interest including fascial plane blocks. Pharmacological advances in the form of the prolongation of drug duration with liposomal bupivacaine are considered. Neuromodulation in the context of regional anaesthesia is outlined as a potential future direction. The growing use of regional anaesthesia outside of the theatre environment and current thinking on managing the rebound plane after regional block regression are also discussed. Recent relevant evidence is summarised, unanswered questions are outlined, and priorities for ongoing investigation are suggested.

INTRODUCTION: With the emergence of the 2019 novel coronavirus and its resulting pandemic status in March 2020 all routine elective orthopaedic surgery was cancelled in our institution. The developing picture in Italy, of acute hospitals becoming overwhelmed with treating patients suffering with severe and life-threatening symptoms from the disease, prompted the orthopaedic surgeons to formulate a plan to transfer trauma patients requiring surgery to the elective hospital to unburden the acute hospital system. METHODS: Under the threat of this pandemic; protocols and algorithms were established for referral, acceptance and care of trauma patients from acute hospitals in the region. Each day, as new guidance on COVID-19 emerged, our process and algorithms were adjusted to reflect pertinent change. RESULTS: The screening of all patients referred, worked well in keeping our hospital "COVID-free" with respect to patients undergoing operations. An upward trend in cases referred reflected the decreased capacity in the acute hospitals due to rising cases of COVID-19 within the hospital network. During the first 7 weeks of the pandemic 308 operations were performed, (31.1% upper limb, 33.4% lower limb, 4.1% spine, 14.1% urgent elective, 17.4% plastic surgery cases). Regular review and audit of the activity in the hospital as well as communication with the referring teams enabled appropriate planning to accommodate the increase in case-mix as the need arose. DISCUSSION: This paper details the steps that were taken in planning for such a change in management specific to the orthopaedic surgery setting and the lessons learnt during this process. The success of the development of this pathway was facilitated by clear communication channels, flexibility to adapt to changing process and feedback from all stakeholders. The implementation of this pathway allowed the unburdening of acute hospitals dealing with the pandemic that was steadily reducing access to operating theatres and anaesthetic resources.

Adults aged ≥60 years now represent the majority of patients presenting with major trauma. Falls are the most common cause of injury, accounting for nearly three-quarters of all traumas in this population. Trauma to the thorax represents the second most common site of injury in this population, and is often associated with other serious injuries. Mortality rates are 2-5 times higher in older adults compared to their younger counterparts, often despite equivalent injury severity scores. Risk scoring systems have been developed to identify rib fracture patients at high risk of deterioration. Overall mortality from rib fractures is high, at approximately 10% for all ages. Mortality and morbidity from rib fractures primarily derive from pain-induced hypoventilation, pneumonia and respiratory failure. The main goal of care is therefore to provide sufficient analgesia to allow respiratory rehabilitation and prevent pulmonary complications. The provision of analgesia has evolved to incorporate novel regional anaesthesia techniques into conventional multimodal analgesia. Analgesia algorithms may aid early aggressive management and escalation of pain control. The current role for surgical fixation of rib fractures remains unclear for older adults who have been underrepresented in the research literature. Older adults with rib fractures often have multi-morbidity and frailty which complicate their injuries. Trauma services are evolving, and increasingly geriatricians will be embedded into trauma services to deliver comprehensive geriatric assessment. This review aims to provide an evidence-based overview of the management of rib fractures for the physician treating older patients who have sustained trauma.

BACKGROUND: The flexor sheath digital block allows effective analgesia and anesthesia for finger pain control. To date, only blind techniques are described in the literature in patients with finger fractures, supposedly due to the superficial position of the structures used as landmarks. We describe an ultrasound-guided technique with a definite endpoint to achieve this block. To our knowledge, this is the first clinical application of this procedure. METHODS: We performed a preoperative ultrasound-guided flexor sheath digital block on a young patient with a proximal phalanx fracture, undergoing an osteotomy with plate placement. After performing the block, opioid-free general anesthesia was performed. A "hockey-stick" ultrasound probe and 1.5 mL of 0.5% levobupivacaine were used to infiltrate the flexor sheath. The "horseshoe sign" was our visual endpoint for successful block performance. RESULTS: At the time of surgical incision, there was no hemodynamic response. No opioids were administered during the case or in the recovery room, and the patient's pain scores in recovery and at discharge were 0/10 on the Numerical Rating Scale. No complications were observed or reported. CONCLUSIONS: The ultrasound-guided flexor digital sheath block is a valid alternative to the blind technique, allowing direct visualization and, thereby, confirming transthecal injection of the local anesthetic. The continuously increasing availability of ultrasound machines in emergency departments and operating theaters may encourage the spread of this technique.

The development of Prothrombin Complex Concentrates (PCCs) has led to better outcomes in patients receiving emergency reversal of warfarin. However, most published data describes the use of PCCs in the setting of major bleeding or emergent major surgery, with little information on neuraxial blockade. We describe a case of rapid warfarin reversal using PCC and subsequent surgery under spinal anaesthesia in an 87-year-old lady, for whom general anaesthesia was deemed high risk. Her international normalised ratio (INR) on the morning of surgery was 1.8, precluding neuraxial blockade; however, it was felt that given, the need for imminent surgery, immediate reversal of the warfarin was indicated. We administered a single dose of 23 units/kg PCC and 5 mg vitamin K. Her INR 1 hour following PCC was 1.2, and spinal anesthetic was administered. The patient then underwent excision of melanoma deposits from her leg and groin dissection. There were no complications, the patient recovered satisfactorily, and there were no thrombotic or hemorrhagic events at 30 days postoperatively. This case study demonstrates a novel use of PCCs; in certain patients, PCCs may be safely used for immediate reversal of warfarin to allow for neuraxial blockade, safer anaesthesia, and better outcomes.
